    Subject: Magnetos
    I do not know the DZ5 magnetos. I suspect they are same as the M9-35 mags that are used on the AI14 Engine. The Housai engine is identical to the AI14 engine. Probably originally license built. The Kamov helicopter engines all had the M9-35 and many of the M14P engines we supplied had the M9-35 magneto. The basic difference to the airplane is the starting system is different as it uses a =9Cvibrator=9D style of start instead of the high voltage =9Cshower of Sparks=9D. We often use the =9CSlick Start=9D for these mags. The other difference as [pointed out is the initial timing is different to accommodate the centrifugal advance system.

To the best of my knowledge there are only four versions of this magneto: 1. The basic M9 of which the DZ5 is a license built copy (though, I guess we could call that 2 versions), 2. The M9-25M, 3. The M9-35M and 4. The M9F. Versions 1 & 2 are auto advance type with a range of 23 to 27 degs. Version 3 is also auto advance but with an extended range of 23 to 37 degs. and version 4 which is a fixed spark magneto with no auto advance mechanism. The basic M9 (DZ5) to the best of my knowledge is the standard magneto on various engines with a maximum RPM of less than 2400. The M9-25M and the M9-35M are approved alternates for the M14P and the M9-35M is the standard magneto for the M14PF. Much of this is my observation and not necessarily fully accurate. Since the M14P and, presumably, the M14PF engines have a much higher maximum RPM than the earlier versions I suspect that the M25M and the M35M (in addition to the extended range of the latter) have a different advance mechanism than the basic M9 (DZ5). I expect there are different counter weights and/or return spring tensions involved. Am I right or wrong? If wrong what is the actual difference between the M9 and the M9-25M? Have at it guys!!

    We have disassembled an HS6 engine and compared it to an AI 14, and were very surprised by the large number of detail differences in most parts of the engines.

    From: doug sapp <dougsappllc@gmail.com>
    Keith, If the air line restrictors, my part number H2-5500-02 have the proper hole size and are in the correct places the gear should not slam up OR down. I have the blank restrictors in stock if you need them. See vol #1 of the parts books, fig 6-1 (Page 292 and on). Look for the word "DAMPER" in the Nomenclature section. You will notice that some of the dampers have different dash numbers, this is because they have differing hole sizes in them. Gear transition speeds can to a degree be altered/changed by increasing or decreasing the size of hole in the restrictor.

    Subject: Re: CK gear checks
    Question Doug, Does both the main AND emergency side of the pneumatic system associated with the gear actuators have the restrictors in both sides (main and emergency) or just the main side have them? In the Yak 52, it is only the main side. When activating the emergency side gear extension test in the 52, the gear WILL come down pretty hard. Thus the reason for doing the gear retraction/extension test as I suggested. Dennis A.

    From: "Bitterlich, Mark G CIV NAVAIR, WD" <mark.bitterlich@navy.mil>
    Doug, does the CJ-6 have flow restrictors in both the normal *AND* the emergency hoses going to the actuators? I really do not know. On the YAK aircraft, the Emergency Side hoses do *NOT* have any flow restrictors, (on the 50 anyway) and with good purpose. If you have a blown chevron seal, restricting air flow in any way can mean the gear will not come down and lock. The idea (from the Russians) is that if you have a real emergency with the gear, you want all the flow the system can generate, and who cares if they "slam" or not, thus no flow restrictors on the emergency side and thus why you have to be careful when actuating emergency gear valve while on jacks. This is how it was explained to me by two Russian Mechs anyway, so take it with a grain of salt. Glad to know about you have the blank restrictors! I very carefully trimmed my holes to allow the gear to go up and down almost perfectly in sync. Why this mattered to me I have no idea, as it really doesn't make much difference. :-) Mark p.s. I just see Dennis asked the same thing! -----Original Message----- From: owner-yak-list-server@matronics.com [mailto:owner-yak-list-server@matronics.com] On Behalf Of doug sapp Sent: Monday, July 01, 2013 12:48 Subject: Re: Yak-List: Re: CK gear checks Keith, If the air line restrictors, my part number H2-5500-02 have the proper hole size and are in the correct places the gear should not slam up OR down.

    What I normally do is to remove top and lower cowls, get ALL the oil off the engine and firewall, start it up and have a guy with a ladder behind the prop to very carefully inspect the engine when it is running. Yes, it is dangerous.. but..... I recently had an oil leak that for all the world looked like it was the rear supercharger seal. I was crushed. That seal can only be replaced by yanking the engine and taking a lot of stuff apart. Guess what? Turns out it was the freaking lower GENERATOR adapter plate that was leaking. Why? Because even with the standard "bend up and lock" Russian nut locks, all four nuts had come loose on the generator studs, allowing the oil to leak out of the lower generator adapter plate. I replaced the seals, and put the nuts back on the studs with split ring lock wasters and also thread sealer and am keeping a close eye on them. Thinking about drilling some nuts so I can safety wire those suckers. Otherwise normal oil leaks are from the valve rocker covers, the valve rocker shaft crush washers, etc. Bottom line, the only way I've ever found to find the leaks is to have the engine totally clean and then run it on the desk with a guy that has good eyes looking at it. Oil leaks can be insidious.

    Guys, I would think you are correct and my better judgement tells me that restrictors on the down side of the emergency system would not be a good idea.

    I don't know what aircraft you are speaking of but if it has a vent line in the oil tank like the CJ, any time the aircraft is less than 1G a little oil gets in that vent tube a coats the belly when the G comes back on. Until I put an air/oil separator on my CJ you can't imagine how much a tiny amount of oil seems to look like quarts when is gets on the belly.

    Back seal on sump Seal on base of tach drive Sump drain Super charger seal Nose case seal Seals on push rod tubes Cylinder base O ring Valve cover seal Push rod tube at rocker box Every dead gummed seal on the accessory case Every danged one of the oil line fittings To name a few places I have seen. Permabond anaerobic gasket sealant works great on those pesky flawed seals. N ice part is it comes apart with a little pressure and a few taps on the case with a rubber sand hammer.

You should receive the first email within a few minutes of your request. The second conformation will arrive in less than 24 hours. You cannot post until you receive the second conformation email message. ***************************** *** How to Post a Message *** ***************************** Send an email message to: yak-list@matronics.com Your message will be redistributed to everyone currently subscribed to the List. ***************************************************** *** SPAM Fighter - You Must be Subscribed to Post *** ***************************************************** When a new post is received by the system, the From: line of the message is checked and compared against the current subscription list. If the email address is found, the message is passed on to the List Processor. If the email address isn't found in the current list of subscribers, it is dumped. This serves to very effectively thwart 99% of the SPAM that gets posted to the Lists. Remember, however, that the syntax of your email address is very important with regard to the configuration of your email application such as Outlook or Eudora. For example, the following two email addresses may be functionally equivalent, but only one would pass the Matronics Email SPAM test depending on which was syntax was subscribed to the given List: smith@machine.domain.com smith@domain.com Either email address syntax is alright, just be sure that you configure your email application to match *exactly* the address you've subscibed to the List. ************************************** *** Enclosure Support on the Lists *** ************************************** Limited posting of enclosures such as pictures, documents, and spreadsheets is supported on the Lists. There are a number of restrictions, and these are detailed below. Please abide by the rules put forth regarding the content of enclosures. These are some of the features and limits of enclosures on the Matronics Lists: 1) Enclosures will only be posted to the Real Time version of the Lists. 2) Enclosures will NOT be included in the Daily Digest version of the Lists. 3) Enclosures WILL BE forwarded on to the BBS Forum Web site. 4) Enclosures will NOT be appended to the Archives. 5) Enclosures will NOT be available in the List Browse feature. 6) Only the following file types and extensions will be allowed: bmp doc dwg dxf gif jpg pdf png txt xls All other enclosures types will be rejected and email returned to sender. The enclosure types listed above are relatively safe from a virus standpoint and don't pose a particularly large security risk. 7) !! All incoming enclosures will be scanned for viruses prior to posting to the List. This is done in real time and will not slow down the process of posting the message !! Here are some rules for posting enclosures. Failure to abide by these rules could result in the removal of a subscriber's email address from the Lists. 1) Pay attention to what you are posting!! Make sure that the files you are enclosing aren't HUGE (greater that 1MB). Remember that there are still people checking they're email via dial up modem. If you post 30MB worth of pictures, you are placing an unnecessary burden on these folks and the rest of us, for that matter. 2) SCALE YOUR PICTURES DOWN!!! I don't want to see huge 3000 x 2000 pictures getting posted that are 3 or 4MB each. This is just unacceptable. Use a program such as Photoshop to scale the picture down to something on the order of 800 x 600 and try to keep the file size to less-than 200KB, preferably much less. Microsoft has a really awesome utility available for free that allows you to Right-Click on a picture in Explorer and automatically scale it down and resave it. This is a great utility - get it, use it! http://www.microsoft.com/windowsxp/downloads/powertoys/xppowertoys.mspx Look for the link "Image Resizer" 3) !! This would seem to go without saying, but I'll say it anyway. Do not post anything that would be considered offensive by your grandmother. And you know what I'm saying; I don't want to see anything even questionable. !! 4) REMEMBER THIS: If you post a 1MB enclosure to a List with 1000 members subscribed, your 1MB enclosure must be resent 1000 times amounting to 1MB X 1000 = 1 Gigabyte of network traffic!! BE CAREFUL and BE COURTEOUS! Also see the section below on the Matronics Photo and File Share where you can have your files and photos posted on the Matronics web server for long time viewing and availability. ******************* *** Digest Mode *** ******************* Each day, starting at 12 midnight PST US, a new 'digest' will be started. This digest will contain the same information that is currently appended to the archive file. It has all of the headers except for the "From:" and "Subject:" lines removed, and includes a message separator consisting of a line of underscores. Each day at 23:55 PST US, the day's messages as described above will be combined and sent as a single message to everyone on the digest email list. To subscribe to the digest list, use the same subscription web form described above, and just select the Digest version of the List. http://www.matronics.com/subscribe Note that you *can* be subscribed to both the realtime and digest versions of the List at the same time. This is perfectly acceptable. Now some caveats: * Messages sent to "yak-list-digest" will be forwarded to the standard email list. In other words, you cannot post messages only to the digest List. * If you are subscribed to both the regular List and the digest List, you will receive the realtime postings as well as the digest at the end of the day. * If you reply to the digest email, your message will be forwarded to the normal list associated with the digest. Important Note: Please change the subject line to reflect the topic of your response! Also, please *do not include all or most of the digest in your reply*. **************************** *** List Digest Browser *** **************************** An archive of all the List Digests can be found online in either plain text or HTML format. These archives contain the exact Digest that was posted to the Digest email list on the given day. The Digest Archives can be found at the following location: http://www.matronics.com/digest ***************************************** *** The "DO NOT ARCHIVE" Message Flag *** ***************************************** At times, your message may concern something that is revelent only to a very small number of persons or to a limited area, and you may not wish to archive it. In such a case, simply put the following phrase anywhere in the message: do not archive Your message will not be appended to the archive, but will be sent to List email distribution as normal. ********************************************** ***** READ THIS - Automatic Unsubscribes ***** ********************************************** Note that if your email address begins to cause problems such as bounced email, mailbox is filled, or any other errors, your address will be promptly removed from the List. If you discover that you are no longer receiving messages from the Yak-List, go to the following Web page, and look for your email address and a possible reason for your removal. The Matronics Email List uses utility called the "Email Weasel" that automatically looks though the day's bounced email for addresses that caused problems due to common things like "user is unknown", "mailbox full", etc. If the Email Weasel removes your email address from the Lists you will find record of it at the following URL: http://www.matronics.com/unsubscribed If the problem listed on the web site above has been resolved, please feel free to resubscribe to the Lists of your choice. ******************************* *** List Member Information *** ******************************* If you have not done so already, please email me your phone numbers and paper mail address in the following format: smith@somehost.com Joe Smith 123 Airport Lane Tower, CA 91234-1234 098-765-1234 w 123-456-7890 h Please forward this information to the following email address: requests@matronics.com I have a file of such things, that I typically use to contact you when there are problems with your email address.

You will also need to Subscribe to the respective Email List as described above to receive the Email Distribution of the List, however. The Matroincs Email List Web BBS Forums can be found at the following URL: http://forums.matronics.com ********************************* *** Matronics Email List Wiki *** ********************************* In an attempt to make it easy to store and find structured and often accessed information, Matronics has installed a Wiki at: http://wiki.matronics.com The Wiki allows individuals to create web pages to contain useful information for other users of the mailing lists and web site. Unlike an ordinary web page where the content needs to be submitted to Matronics for inclusion, the Wiki permits the users to construct their own pages and have them visible immediately. While constructing pages for the Wiki is not difficult, some may not be comfortable building pages. In that case, simply prepare the text and any images and email it to: wiki-support@matronics.com One of the volunteers on that list will take your submission and construct a Wiki page for you. Often someone produces a particularly useful posting in email one one of the Lists that would be of general interest. In that case Matronics may take that post and convert it into a Wiki page. ********************* *** List Archives *** ********************* A file containing of all of the previous postings to the Yak-List is available on line. The archive file information is available via the Web and FTP in a number of forms. Each are briefly described below: * Yak-List.FAQ - Latest version of the Yak-List Frequently Asked Question page (this document). * Yak-Archive.digest.complete - Complete file with most of the email header info removed and page breaks inserted between messages. * Yak-Archive.digest.vol-?? - Same as the file above, but broken up into small sections that can more easily handled. * Yak-Archive.digest.complete.zip - Same as the Yak-Archive.digest.complete file above, but in PKZIP format.

You won't find any PopUpAds, flashing Banner ads, or any other form of annoying commercialism on either the Email Messages or the List web pages associated with the Matronics Email Lists. Every year during November I run a low-key, low-pressure "Fund Raiser" where, throughout the month, I ask List members to make a Contribution in any amount with which they are comfortable. I will often offer free gifts with certain contribution levels during the Fund Raiser to increase the participation. The gifts are usually donated by companies that are themselves List members. Your Contributions go directly to supporting the operation of the Lists including the high-speed, business-class Internet connection, server system hardware and software upgrades, and to partially offset the many many hours I spend running, maintaining, upgrading, and developing the variety of services found here. Generally Contributions range from $20 to $100 and are completely voluntary and non-compulsory. I ask only that if person enjoys the Lists and obtains value from them, that they make a Contribution of equal magnitude. Contributions are accepted throughout the year, and if you've just subscribed, feel free to make a Contribution when you've settled in. The website for making SSL Secure Contributions is listed below. There are a variety of payment methods including Visa and MasterCard, PayPal, and sending a personal check. If you enjoy and value the List, won't you make a Contribution today to support its continued operation? http://www.matronics.com/contributions Thank you!

You are encouraged to read it carefully, and to abide by the rules therein. Failure to use the Yak-List in the manner described below may result in the removal of the subscribers from the List. Yak-List Policy Statement The purpose of the Yak-List is to provide a forum of discussion for things related to this particular discussion group. The List's goals are to serve as an information resource to its members; to deliver high-quality content; to provide moral support; to foster camaraderie among its members; and to support safe operation. Reaching these goals requires the participation and cooperation of each and every member of the List. To this end, the following guidelines have been established: - Please keep all posts related to the List at some level. Do not submit posts concerning computer viruses, urban legends, random humor, long lost buddies' phone numbers, etc. etc. - THINK carefully before you write. Ask yourself if your post will be relevant to everyone. If you have to wonder about that, DON'T send it. - Remember that your post will be included for posterity in an archive that is growing in size at an extraordinary rate. Try to be concise and terse in your posts. Avoid overly wordy and lengthy posts and responses. - Keep your signature brief. Please include your name, email address, aircraft type/tail number, and geographic location. A short line about where you are in the building process is also nice. Avoid bulky signatures with character graphics; they consume unnecessary space in the archive. - DON'T post requests to the List for information when that info is easily obtainable from other widely available sources. Consult the web page or FAQ first. - If you want to respond to a post, DO keep the "Subject:" line of your response the same as that of the original post. This makes it easy to find threads in the archive. - When responding, NEVER quote the *entire* original post in your response. DO use lines from the original post to help "tune in" the reader to the topic at hand, but be selective. The impact that quoting the entire original post has on the size of the archive can not be overstated! - When the poster asks you to respond to him/her personally, DO NOT then go ahead and reply to the List. Be aware that clicking the "reply" button on your mail package does not necessarily send your response to the original poster. You might have to actively address your response with the original poster's email address. - DO NOT use the List to respond to a post unless you have something to add that is relevant and has a broad appeal. "Way to go!", "I agree", and "Congratulations" are all responses that are better sent to the original poster directly, rather than to the List at large. - When responding to others' posts, avoid the feeling that you need to comment on every last point in their posts, unless you can truly contribute something valuable. - Feel free to disagree with other viewpoints, BUT keep your tone polite and respectful. Don't make snide comments, personally attack other listers, or take the moral high ground on an obviously controversial issue. This will only cause a pointless debate that will hurt feelings, waste bandwidth and resolve nothing. - Occasional posts by vendors or individuals who are regularly subscribed to a given List are considered acceptable. Posts by List members promoting their respective products or items for sale should be of a friendly, informal nature, and should not resemble a typical SPAM message. The List isn't about commercialism, but is about sharing information and knowledge. This applies to everyone, including those who provide products to the entire community. Informal presentation and moderation should be the operatives with respect to advertising on the Lists. ------- [This is an automated posting.] do not archive
