Hi,

My name is Josh and i am currently taking an Engine srv. class at my high school in south western pennsylvnia. Our teacher has brought in an old, what we beileve to be a 1941 Cletrac.Its is a crawler and we think the engine(4 Cyl.) was made by hercules. Me and a few other students are in charge of the engine and we were wondering if there is any diagrams ou there that have all the parts, gaskets, assembly order, etc. out there to make this project easier. The tractor is in bad shape and any links, stores in the pittsburgh area, pictures or any help of that sort whould be very appriciated.

Thanks
Josh

Josh 33,
Those shims are for shimming up the correct bearing clearances.
They will be the same shape as the con rod and big end cap faces (plus most of the bearing thickness) and will originally come as a basic 'shim pack' of a certain thickness containing several different thickness shims).  Shims are removed as bearings become worn (or at least as clearances increase, but journals/crankpins still remaining within ovality specs), or maybe added for clearance when new bearings were scraped in.
Hope this helps.  You will, of course, know that these old engines did not just have thin walled bearing shells fitted as do modern engines.  They were built to run slow and be very tolerant of misuse/abuse, and bearing technology, although good, was of using much more bearing material than the bare minimum (cost) as they do these days.
Regards, RAB
