Crankshaft Dimensions

[DaveHagen]

Hello all, I'm trying to find the dimensions for the crankshaft in a 276D tractor with a serial number 200107. The engine model is a 3T84H. The Stroke of the engine is 3.375, the connecting rod journals are currently close to 1.848" while the mains are close to 2.360".

I'm wondering if there are undersize bearings available (and what sizes) and what the Standard dimensions for the journals should be.

I can find the diameter to match mine on a different Yanmar engine for the rods, but not the mains. I guess what I'm really asking is, Does anyone have the engine sevice manual for this engine.

Thanks for reading, think green! /forums/images/graemlins/smile.gif
