I agree Roger,
I will go thru the manual again and copy the check pages and some of the
other stuff. I find it useful to collect data from various sources on this
engine. I must have a library about a foot thick just on this engine. It's a
far cry from the info I collected on the Lycs or Continental engines where it
was generally available in one complete book and easy to find. As an
example find the torque for the exhaust nut that attaches to the stud at the
exhaust flange on the cylinder head. Now I know with your experience you will
probably know where to find it. I looked thru all the manuals and finally ended
up calling Dean at Lockwood and he looked it up on his computer. This is
just an example. I had to remove an exhaust pipe on a Paradise LSA in order to
remove the oil filter for an oil change. (there was no other way) I wish
there was a COMPLETE torque table in one location. I know if all else fails
you can go by the fastener size(or the "elbow" torque wrench) but certain
applications differ and I want to do things correctly. That is why I will pay
big bucks for the 17 mm coolant hoses for my engine that I have been unable to
find except at the Rotax distributor.

Dick, The complete torque table you seek is in the Illustrated Parts

Hi Dick and all,
This sounds just like a Rotax test question. The answer Dick is in the Parts manual
pg. 24-6 item 38 of the May 2009 edition. Or page 166 from the very front
page.
Several torques are located in the Parts Manual for specialized areas. An exhaust
stud/nut won't get the same torque as another nut and bolt the same size because
of it's special duty area i.e. the very hot and
expanding & cooling exhaust flange area.
Common everyday maint torques are usually in the Line Maint manual, when it gets
a little more toward the Heavy maint items then it is there and special torques
are in the Parts Catalog.

Hi Dick,
I have been unable to contact anyone at Rotax to confirm this but I
believe the new manual has at least one important typo or translation
error. On page 32 of the last chapter, there is the basic throttle
setting procedure. At step 5 it says :-
"Pull out feeler gauge and then turn each idle speed adjustment screw 1.5 turns
_counter clockwise_."
This does not make much sense and is contrary to the instructions in the Rotax
video and the earlier yellow manual which clearly say "turn each idle speed adjustment
screw 1.5 turns _clockwise_." Perhaps someone else knows how to get
this corrected by Rotax.

Went to Office Depot and gave them the URL for the new manual and they were
able to print it , bind it with wire coil and covers for $17. That was good
for me as the thing is almost 1/2 inch thick printed both sides.
I read it last night and it is a much better manual than the old one even
though the English is much the same as the English found in the instructions
for a Harbor Freight tool ! But then I can't speak German so what the heck.

| Subject: | New Rotax Maint Manual Changes |
Hi All,
Just thought I would do a little reflecting on just a couple of the new Rotax "Line
Maint Manual" changes.
I don't think they are all good for us, but that's my personal opinion and may
not reflect your perspective..
1. Compression test is every 200 hrs. which is the same as the old manual, but
the change is you can use a test pressure of 80-87 psi.
87 psi was the old standard test pressure. 80 psi test pressure was for A&P's that
didn't know better, now they will at least look like they knew. I always do
a compression test at every 100 hrs. or annual for my clients. It only takes
a few minutes and might point to a problem much earlier.
2. The gearbox check was moved from 800 hrs to 1000 hrs. for those that use 91
oct. unleaded. For those that use 100LL more than 30% of the time then a gearbox
check is due at 600 hours. That usually means those that are using a lot of
100LL will need to have the overload clutch sent in a cleaned of all the lead
deposits. Only a couple of places in the US does this. You can't do it yourself
very well because you need a jig, a special tool and a lot of force. CPS does
this cleaning.
3, To me this next one isn't such a good idea. They did this many years ago and
had some issues then.
Only check, clean and gap the plugs at 100 hrs. and replace at 200 hrs. If you
have seen many plugs with those time intervals and flown some of those engine
with 100 plus hours with 100LL then this is still a bad idea today.
The plug gap recommendation has changed a little. It is still within the older
specs, but is slightly different from the old manual. New gap recommendation is
.023-.027. Most everyone I knew used to gap at .028 for warmer weather from
April -Nov. They used to say you could gap as low as .019 for really cold weather.
Doesn't say anything about the lower gaps in the new manual. Good question
when I go back in Feb. for my Rotax update class.
4. Here is one I really lift an eyebrow about.
Looks like they went to 50 hrs. on the oil and oil filter change for 100LL and
100 hrs. if you use 91 octane unleaded.
If they were so adamant before about sooner oil and oil filter changes being detrimental
to the engine all these years, what happened to change that? If the
100LL made such a mess and it did if you ever saw and engine apart why has that
changed?
The oil is the blood of your engine and you just got a TBO extension, why play
with the success that got that extension in the first place. Personally 50 hr.
oil changes still work for me, but it's up to each owner. I would highly recommend,
plus your supposed to do oil analysis to be compliant with the new TBO
and it should be done anyway. Cost is a whopping total of $19.95. The kit can
be ordered from Lockwood and postage is all prepaid. You get the results online.
Once every 100 hrs. should be good.
5. This is just a reminder on this item. Your gearbox friction test results should
be between 264-531 in/lbs. The higher the better especially for cold weather
starting. If you are in the mid to upper 400's then great. If you are in the
low 300's you may need a shim or spring washer change sooner than later.
