[Farmall] Looking for some help with a 1928 Regular.

[Justin Weber]

The bearings are bronze.  The front will be held in by bolts thru a 
flange, and the next two will be held in by bolts  that keep the bearing 
from rotating.   I may have a NOS front and center cam bearing, but the 
rear seems to be the one I seldom see.   These engines run at such a 
slow speed, that the cam bearings are in good shape most of the time.

One of the things that went with the deal was a rusty old 1928 Farmall that had belonged to what had been the farm back when. Best we could research it had been parked sometime in the 50's. How it got inside the warehouse we don't know, but there it was on steel.

That might have been a soft headed decision on our part but over the past year the teardown has proceeded on the engine and it has been fun. Mag was trashed, governor possibly (another task) but amazingly the block and head seem solid (so far) and most of the pieces seem to be ther in some sort of condition. We did pick up a 1930 Regular as a parts tractor just in case.
