Flywheel Shims?

[jack orchard]

I have found .025" and .050" flywheel shims for the 8BA engine. I assume they are used to make up the difference in flywheel height after the wheel is surfaced. Are these commonly used?
If so, how do i measure to determine how much shim i need?
What would be the correct dimension?
Many thanks to all.,...jack

Do not shim the flywheel.
You could shave a lot of flywheel and there would be no functional difference.
I believe that the pieces you have serve as washers for the flywheel bolts.

Have not seen shims but have seen the plate that stops the locating dowels from backing out

I looked at a 1951 Ford F1 239 motor at the Rock Auto web site. They call them shims, and they don't look like the ring that fits under the crank bolts. Could they be made to set the depth of the ring gear for the starter?,...jack

No, don't think so...

Sound like somebody found a solution to a problem that nobody here knew existed.

Flywheel Shim


Part Number : FS-11
Features & Benefits

ATP Flywheel Shims install easily restoring machined manual transmission flywheels back to the proper height. On automatic transmissions the shim takes up excessive clearance caused by engine crankshaft endplay or by installing a rebuilt torque converter or rebuilt front pump.

• Saves money by allowing the re-use of the flywheel
• Easy to install
• For automatic and manual transmissions

I don't under stand, do you mean those shims go between the crank and the flywheel? It don't sound like a good idea to me, the dowels on the crank that line up the wheel don't stick out very far. Walt

If you shim the flywheel (seems odd to me but) would that not also change the starter tooth to flywheel gear pattern?

I don't think there is much good in offsetting gear to gear alignment....

some non adjustable hyd.clutches need them or clutch may not release properly after flywheel grinding.

Techpak Fitsall transmission parts came on the scene to produce some Automatic transmission repair parts in the early 90's They filled a nitch for some needed automatic parts and they produced some other parts that they tried to make you believe you needed such as flywheel shims. (I think they were the first to produce flywheel shims). I have never used flywheel shims and have never seen an automotive flywheel that would need them. I have seen tractors and trucks with ceramic clutches that could potentially use them but if the flywheel is worn that bad it should probably be replaced.

P.S.

On our old Flatheads, any correction to be made for or because of flywheel resurface is done at the clutch linkage, of which there is lots of adjustment.
