Anti-seize on bolts under truck?

[MoGas]

<<<<<<<<<<<<HIJACK IN PROGRESS>>>>>>>>>>>>

How many of us here are aircraft mechanics? RavenTai, IBCRUSN, Myself (MoGas), Any others? What are your fields? I got my A&P while in the Navy. I was a Flight Deck Troubleshooter with EA-6B's. Used it at a little FBO for a while until the guy started bouncing our paychecks (while buying a King Air B90), but I love Flagstaff so I found another place that can use my skills.

Darwood, I did the same, the torque spec for the flange bolts must be close to yield of the studs, I had some rust on the drive flange hardware, I was not thinking and heavily greased on reassembly in an attempt to stop the corrosion (grease is the worst) , most of the studs on the first wheel could not make torque either shearing or stripping , got new studs and nuts at the dealer cleaned everything with solvent and not a single problem on that same wheel, nor on the other side with old hardware, painted them after assembly to control corrosion,


-B- not all of those 3k posts are correct, there are quite a few fliers out there please nail away when you find one :whoops:

I did not know there were that many of us here,

Instigator is also an A&P, leaned on my tool box most of today

have a good buddy that was on the Carl Vincent worked on F-14s IIRC, drives a Heep CJ-7 that he built most of, I have to admit it is nice,

I went to A&P school after high school, worked at a small repair station working mainly heavy checks on Cargo DC-8s, after 9 months got on with a major airline, Jan 12 will be 8 years now, started in overhaul on 727s ( I miss that aircraft) working mostly engines, AC, elevator and rudder and a little structure, currently work short checks and non-routine on all of our current fleet (737, 757, 767, 777, MD88/MD90 ) and also contract work on other carriers aircraft C-40, MD11 (POS) , so far I have survived 3 rounds of layoffs and 2 pay cuts the next will likely catch up to my seniority level. will hopefully give me an opportunity too move up to something else like you did, it is a cyclical trade, and defiantly in a slump right now, I am not sure if it will ever fully recover though.

I just put grease or Breakfree on mine...

break free CLP? your other hobby is creaping in, I have wondered abotu using break free a few times. it is good stuff.

yup, read some extensive tests on corrosion using many of both usual lubes and specialized antirust agents. Breakfree CLP came out way on top. Exceptional product IMHO...

I believe John Davies is also an aircraft mechanic or he was in a prior life.

Yep I was

I worked as a General Aviation A&P for about 18 years before giving up due to health concerns - it was giving me ulsers. I worked on helicopters and fixed wing stuff up through Lear 35 and Citation II class jets, with a few small Falcons now and then. Mostly King Air turboprops and Citation I jets. I don't miss working on those POS Cessnas, but I always liked wrenching the Beech products - they are, for the most part, fine aircraft. I also enjoyed the turbine engine work a lot - its very technical and precise, and there is no bull sh*tting allowed.

I miss some of the work... the stress and bizarre working hours I do NOT miss. I am presently a stay at home dad raising my two kids.

This is kind of a hijack but oh, well.

I started at the airlines, saw a guy almost get killed because he was following the "normal" procedures. Quit there and worked light corporate stuff (single pistons up to Citations and Falcon 20's) for a few years. That slowed down prior to 9/11, quit my job finished my B.S. Went to work in QA for Garrett in NY on stuff from Lear 35's up to my product line, Gulfstreams and Falcons. Garrett (Landmark) closed the facility, recently moved to South Jersey for Raytheon as the chief inspector. I must be nuts, I have had several chances to get out of this biz and still come back for more punishment. You really have to love aviation to stick with it. Oh well, I'm still young there is hope for me.....some day.

 

[brianinaustin]

Ah well... hijack away. The sliders are on now anyway. I did not use any anti-seize, but I didn't clean the lube off the threads either. Without any torque spec, I just went with pdt. Thanks for the education... Brian

To the A&P guys, thanks! I'm an industrial machine designer and builder these days, probably will get back to aviating in the Fall. What about threadlocker? I usually use copper anti-sieze in high-temp applications, and zinc anti-sieze anywhere else on my vehicles to combat corrosion. I've had good luck with moly grease from Mr Moly, it seems to cling better than most. I've started using medium-strength threadlocker in the engine bay, it seems to seal and protect the threads, as well as prevent loosening. On aluminum parts there's less tendency to over torque and strip threads when I'm using threadlocker. I'm not sure if it seals and protects the threads as well as anti-sieze, but I know it dries and stays put while anti-sieze could wash out a bit. I've thought about using low-strength LocTite instead of anti-sieze on the chassis, what say the experts?

 

[sdbrassfield]

I think scottm has got it. Anti-sieze It is designed to be used for hi-temp applications and applications involving aluminum or aluminum parts with steel bolts.....

 

[CruisinGA]

I was under the impression to never use any form of threadlocker with aluminum threads? Quite possibly an incorrect assumption..

[IBCRUSN]

Anti-seize can be used on anything that you want to take apart in the future. I don't use the AL stuff except as a last resort, the copper stuff seems to work much better.

As far as thread lock in aluminum components; I have never seen it used or a call out for it in aviation (fixed wing). Rotorcraft may be different as their whole purpose in life is to shake apart. I used to use thread lock on my gas R/C cars/trucks because they vibrate like mad.

 

[scottm]

I just checked the Permatex site, no mention of aluminum with threadlocker, I think they'd mention it if it was a problem. I've seen it specified for aluminum parts, and I've specified it in my machines, hopefully it's ok. I know it's not good for my son's snowboard binding screws, the solvent can dissolve the plastic around the thread inserts. I have threadlocker drying on some screws right now, it should be safe once dry.

 

[RavenTai]

I do not use thread locker much at work. All fasteners are required to have a secondary method of anti-rotation besides the torque applied to it, such as cotter pins, safety wire, and on smaller fasteners pinched oval bored nuts, large bolts often get a small bolt run through the nut and bolt like a sold cotter pin. Thread locker does not qualify AFAIK.

I have seen it around, I think the arts and crafts crew in the cabin use it.

I wish they would, I've taken to carrying all the tools I can get away with, and duct tape and superglue. There's almost always some knob or trim piece about to fall off in the cockpit. Passengers really enjoy watching me tape an oxygen panel back up or put an armrest back on. The machines I design also get secondary keepers, but sometimes there's no way, or I'm working with an old design or customers design.

What do you use on water pump and intake manifold screws? Gotta use medium-strength threadlocker there. I'm sold on the stuff for my cars.

I'll bet you get some funny looks from the pax , I dont think our pilots would be willing to do that, not in thier contract. I think many of our pilots would refuse the aircraft if a mask door was down. a mechanic would be called to tape it up. would be propperly fixed that night by a line guy.

so far I have not had a problem with anything backing out on my cruiser, I have only used thead locker on the rear locker shift fork as it was called for there.

I have used antiseize in a few spots, generally only where corosion was found. generally dont fund much on the engine.

 

[Tools R Us]

I use red loc-tite all the time on air tools, steel bolts into aluminum with no issues, impacts and grinders whole purpose in life is to shake apart. A little heat from a torch and they back right out.

 

[scottm]

Yeah, I won't touch it at the gate, but there have been times we delayed takeoff for a quick-fix out on the taxiway. Of course I've always got masks hanging after my landings, darn those flimsy mask doors

 

[RavenTai]

LOL, yea blame the mask doors, you must be ex-navy looking for that three wire


but seriously those things are f-ing flimsy with chincy plasic latches, much of the interor is junk.

You know, I can usually tell if a pilot was Navy or Air Farce by the landing. The Navy one is always right on the numbers, a little harder and shorter and hard on the binders and sometimes you can catch alot of power fluctuations on glide slope.

Air Farce pilots seem to land it smooth as a Prom Queen's thighs and use the whole runway for rollout and sometimes you can get a Mr. Fancypants that aerobrakes it. Smooth.

Personally, I like a smooth landing better but, if I am flying in weather, I am far more comfortable with a Naval Pilot.
