Capen" Subject: LycomingEngines-List: Oil filler tube loosening Engine-gurus..... Is there a way to keep the Oil filler tube from loosening? I tighten it... I safety wire it... I fly it a couple of times...and it's loose again! My thinking is that when I check the oil(cold-ish), it's turning a little tighter. It's not leaking that I can detect - but I'm worried about wearing out the safety-wire hole on the plastic. Any suggestions as to how to cure this? Does anyone know the proper torque value for the tube (and what reference document)? I can get a torque wrench on it - but can't find the value. Would it make a difference to torque it with the engine hot? I have a replacement gasket and some fuel-lube for sealant - I would love to get this one right! Thanks, Ralph Capen ________________________________ Message 2 _____________________________________ Time: 07:13:21 AM PST US Subject: Re: LycomingEngines-List: Oil filler tube loosening From: FLYaDIVE Ralph: Here are a few tricks: 1 - Clean the threads - both of them with MEK as well as the gasket. And re-install... YES, with the Safety Wire - BUT! It MUST PULL - Not just look good. 2 - REPLACE the gasket. If old it will be squashed down and loose its push-back abilities. 3 - Do #1, ;-) And then put a lite coat of High Temp RTV on the Base of the threads of the tube and then put on the Gasket and then another lite coat over the top of the Gasket. SNUG down - REMEMBER the oil fill tube is ONLY PLASTIC. Then install the Safety Wire - Once again... The wire MUST pull on the tube, not just sit there. START the Safety Wire FROM the tube and make sure it pulls from at least 180 degrees away from the anchor point on the engine. Wrap Around. 4 - I was recently informed about a very good gasket -"supposedly"! That eliminates your issue. I have never used it as yet, but I do plan on doing it. The gasket is offered by a company know as Mr. Gasket. I tried to find the site but could not get to a point where a single gasket that fit out tube could be found.

Capen" Subject: Re: LycomingEngines-List: Oil filler tube loosening OK - I've received a number of good suggestions...: Clean the threads Use a new gasket Use a different type of gasket Use RTV Safety wire pulling tight in both directions wrapped around the tube. Don't tighten the dipstick too tight when checking the oil. I'll be using most of these this weekend. I'm still looking for the torque value for the tube...

S afety wire should always "pull" to the "tight" position per the FAA's AC-43 "Standard Practices" manual (see the section on safety wiring). Other than that, all the suggestions appear reasonable to this former Army Helicopter maintenance test pilot and technical inspector (who only knows a very little bit about Grummans).
