Hey, John- - - - -do you remember that brake lining riveter that followed me home awhile back? It's getting repurposed. Without compromising its original job of installing riveted brake linings, I'm making a new set of dies that can punch out brass shim stock for stovebolt connecting rod and main bearing adjusting shims. I might even make a few from our favorite shim stock material- - - - -beer cans!

Jerry -- That's cool! Charlie (who gave it to me with the truck) would be pleased. We do, of course, need pictures of this ...

Since those factory made shims are getting as scarce as a chicken with lips or an honest politician, it makes sense to be able to make accurate replicas from a sheet of brass shim stock. I've ordered some oil-hardening tool steel to make a set of punch dies to make accurate holes, and the outside shape can be trimmed out with a pair of heavy duty scissors or tin snips.

Did all years of Stovebolts utilize these main/rod bearing shims? I had in my head this was just on the Babbit engines.

The early 235 and 261 full pressure engines (1954-early 55) with the upper main bearing shells positioned by a dowel used shimmed main bearings. Rod shims were only used on Babbit rods, but I build one of those engines on occasion. Even the upgraded spray-oiler rods with insert bearings can have the oil clearance shim adjusted.

Reason I ask: Rock Auto’s listings for later year main bearings says something like “must be used with shim kit part # xxxxx”

Rock Auto needs to come talk to my garden- - - -I'll save a fortune on fertilizer. If the upper main bearing shells have a locator tab at the block parting line instead of a dowel, they don't need shims. That change was made in mid-year 1955.
