I recently brought home a 63 Kenworth W923 that supposedly has a 335 cummins in it. I however, don't have a date plate on the timing cover where it should be. There is a single rivet remaining, but sometime in its life, this engine has forfeited its identity. The engine number stamped on the block is 315623 with the sets of numbers "131600" "40-001", and "8 8 62" casted.
I can post up pictures if required.
Also, it would seem that the crankshaft dampener seems to be a problem item if it is a 335. Is there a way to "check" my dampener to see if the rubber has hardened out of spec, or would I be better off just to search for a replacement just to be safe?
My collection consists of old tractors and pickups, so mechanicing isn't new to me, but some of the intrinsic semi parts are surely new to me.
Thanks for any help/insight!
Video included, if it'll be any help, first engine look shown at 8:45. Unfortunately, I put my inexperience shifting on a 4x4 out there for all to see! Not like shifting a 13, that's for sure.
