Aluminum Flywheel

[jrvariel48]

I'm installing an aluminum flywheel and I wanted to know if the original spacer between the crank and the flywheel should be reinstalled.
Thank you, Joe

No spacer. Shield maybe. not a spacer

[jrvariel48]

Thanks Tinker!

Curious what spacer? flywheel to crank? I learn something everyday.

Hi Joe, wasn't sure what "plate" you meant, there's generally none between the crank and the wheel, but there is a dowel pin retainer plate goes on after the wheel.

It keeps the locating pins in place in the event they ever come lose. I have a bunch of these plates here!

Thanks, Gary in N.Y.

P.S. Here's a shot of one, also will get back later today on the pressure plate bolts, I believe have some at the shop, will be getting them here later today!

Yes it should and it goes between the bolts and flywheel and NOT between the crank and flywheel.

Make sure your flywheel bolts are long enough to catch ALL of the crankshaft flange threads. Aluminum flywheels can have a thicker bolt flange - making the actual original bolts too short.

I always buy new ARP bolts, I do use the above plate and I always use Red Loctite on the threads.

The only thing to ponder is many of these plates are really scared up - so using hardened steel flat washers under the flywheel bolts is another way to do it. I've never seen the locating pins be loose, but Gary does have a good point on that aspect of using the full plate.

Curious about using washers versus a plate?

Guys Joe is asking about a spacer plate between the crank and flywheel. Hes not asking about a plate between the flywheel and mounting bolts. Joe since there is a difference between early and late Flathead flywheels which causes the ring gear heights at times to not be the same and rear flywheel surface interference a spacer between the crankshaft and flywheel is used at times if a late flywheel is being used on the early crank or if the early flywheel is being used on a late crank. The exact offset difference is not a lot but at times will create two possible problems one with the starter bendix and two some interference with the oil pump idler gear drive cover to the rear of certain flywheels.

That's correct Ronnie! What's the best way to check this before the motor is installed??!! I was planning on using a Powermaster starter and was wondering how to get the correct backspacing. I see they make one for the French block which I was told is the one to use.
Anybody have this set-up?
Thank you!

Joe when i use the Powermaster starter or any other brand I always measure how far the gear will come out from the starter surface that sits on the oil pan i use a simple steel 6 inch ruler that has a T slide. The T slide is placed on the back of the gear {the back being the farthest in towards the transmission} when the gear is fully pulled out of the starter. Next i simply place the ruler on the starter surface of the oil pan and now see how far into the ring gear the starter gear will engage. The same measuring can be done with a dial or digital vernier.
When i make the flywheels for my race car I always have to measure the gear engagement If I find its not what I want I machine the starters mounting surface so i get as much gear engagement as possible.

Be very careful, of any spacer that you put between the crank and flywheel.

It needs to be perfectly flat. Not just "look" flat but, measured. Just a burr or .001 variation, will put your flywheel, out of spec for axial run out at the outer diameter.

Thank you everyone! Great advice as usual!

While on the topic of the flywheel, can someone point me in the right direction for the correct bolts for an 8BA and the correct pilot bearing/bushing.
Thank you, Joe

Here's some flywheel bolts.

Here's a bearing like the one I used.

Joe the pilot bearing you need is simply a 203 bearing its very common used for lots of applications you should be able to find them for way less than $10.00

Thanks 19, but I'm looking for the flywheel to crank bolts.

Thanks Ronnie! I don't know if this makes a difference or not, but this would be for a Ram aluminum flywheel. I have a pilot bearing from Speedway and it's a loose fit. I would think the hole size is the same, but I could be wrong.

[jrvariel48]

Also wanted to mention it's a T5
Thanks

Will these work? I recall that in 1970 when I installed a WEBER aluminum flywheel in my 8BA I used the stock flywheel bolts.
