I just put the flywheel back on my '71 350ci. I torqued the bolts to 60 lbs as the Haynes manual suggested, using a cross pattern.

I'm now wondering if that's good enough, or should I have used some high-strength thread locker for extra measure? I've still got the trans out, but the bellhousing is already in place.

I've got visions of the flywheel coming loose and cutting my legs off!!!

Are you guys doing anything extra when re-installing flywheels?

Thanks...

HI, You dont' need any thread locking compound on the bolts, If they are torqued as yoy say they are fine.

You don't need thread-locker. They weren't installed that way at the factory. But I always put locker on the flywheel and clutch bolts since it's not something I want to have to think about. Yes, if you properly torque the bolts, they'll stretch properly and be secure...probably forever. But a couple drops of thread-locker makes me sleep better.

While it is not required and the bolts come with lock washers I always use loctite the same as gerry72

I have to admit I've gotten into the habit of using thread locker whenever I can. With the exception of head bolts and water passage bolts I use it on everything. Had a bad experience with a caliper coming loose on my 78 when I first got it back in 95. Really chewed up my wheel and scared the you know what out of me.

ive yet to see a lock washer on any flywheel bolt any where, on any car. i use the blue loctite on smaller fasteners and things that may need to be removed. red is for larger and more permanent fasteners. i use the blue on almost everything i service. probably unessasary and ****.

Thats funny, I have yet to see any without. Vettes, GM trucks, Jeeps, Camaros.... They have all had the star style lock washers on them.

I just bought a flywheel bolt set two weeks ago...came with star washers

My ARP flywheel bolts came without lock (star) washers and had a note saying not to use lock washers.

Carguy4sure - whose bolt set did you buy that came with washers?

b71vette

at least on the SBC-LT1 for 1971. I installed new ARP bolts and they did not come with or require the washers. I did use blue loctite though.

I recently removed the flywheel from my 72 LT1. It had star lock washers. I bought replacement bolts from Zip and they came with the star lock washers. I put them on; should I remove them?

I use blue on most everything I don't want to take a chance on coming loose. I am also a firm beliver on using anti-seeze most other places.

No thread lock, used ARP moly lube, no problems yet.

pauvil

Yes, from the factory they are and any engine book will say the same.

Never use green . I used blue on my flex plate just to be safe.

redc3

sorry, ive yet to see any style lock washer on a flywheel bolt. as a matter of fact, we just put a center force in my buds 97 cobra and guess what? no washers. how would you get correct torque set on this kinda important fastener with a crushable star washer under it? id guess if youve found washers, they have been installed by others over the years. just my .02

How permanent is the red thread locker? Norval and others seem to be using the blue. Is red a bad idea if those bolts might need to come out someday?

LiveandLetDrive

There's no reason you shouldn't be able to break it down with heat but I still play it and safe use blue on small fasteners. Don't need to be breaking things off.

Does anybody have experience with the glue-stick type Locktite? I have some but haven't really used it yet. I hate the liquid type dripping off everywhere...
