The Stovebolt Site Forums The Shop Area Engine Shop Looking for Flywheel bolt locks for 216

I am looking for a set of flywheel bolt locks for my 216, Anyone know where I could fine a set?

Some reproduction parts vendors sell bolts but they include star washers. Some people have recommended the star lock washers and a Loctite threadlocker.

Try posting a Parts Wanted ad in the Swap Meet.

Maybe someone will post a vendor that sells something like the original plates.

You can always make yourself a new set.

I did not use the factory bolt locks and opted to use blue "Loctite". Have been doing it this way since my first engine rebuild 35 year ago without any failures/issues.

Thanks! I will just pick up some star washers and loctite them in.

Can someone tell me when, in gereral, you would use a star washer as opposed to regular lock washer?

Good question Dennis and I usually ask myself the same question. The answer I gave myself is a star washer when bolting sheet metal and split washer when bolting steel brackets or cast parts. Also, star washers are less susceptible to breaking, so I believe a star washer is a better choice for the flywheel even though it goes against my rules above. Also, the star washer is thinner and for the flywheel this might be important for clearance issues.

With that said, I don't see the need for any type of lock washer if using thread locker.

Dennis,

The main different is appearance is that the star washer is thinner. Maybe this, in combination with the thinner head on the bolt, are desirable in having less "head protrusion" on the surface of the flywheel.

An Internet search finds statements that there is much more "bite" contact area on a serrated/star washer than on the common split/spring lock washer.

I would add that the heads on those flywheel bolts are thin for a reason, probably clearance. A split style lock washer would be thicker than the original flat washer with the bendable corners, possibly causing interference with the clutch assembly.

Thanks for the answers guys. Learn something new every --- once in a while.

George,

That's the ticket.

What words do/did you use in the search on Ebay?

Thanks,

Tim, Found these by going back to sellers that, I previously bought vintage GM NOS parts from.
Seems that the one's that I bought from
before keep finding more nos parts.
This seller has slowed down some in
the last year or so.

If I were to search...I'd search:Flywheel Locks.

The number thats on the box: 136857

If that's a valid GM part #.

Seacoast Chevrolet in Wannamassa, NJ has ( 64 ) of them.
Seacoast is only ( 4 ) miles from me.
There phone # is: 732-918-1100 .

Tim, send them my photo to see if it's the
same part they have in stock.

Let everyone know how you make out.

Wish I had the time and my machines set up. I only made enough
for a few engines when I made these for my 216 rebuild:

Today I installed my flywheel on my (41 Chevy truck AK)216 motor using Chevys of the 40s part # 839756 flywheel bolt kit. It came complete with all grade 8 bolts c/w star washers.( about $10.00 set) I installed using thread locker and was really pleased with the quality.
good luck with your project.
