Looked at a White 2-135 4wd series 2 that the owner says has a broken crank, it started making a knocking noise so he stopped, towed it back to the shop. Diesel mechanic came
over, owner started it up but mechanic said shut it down immediately. They pulled the engine, valve covers and the pan, checked everything over and found there was a few thou
play between the crank from one side of one bearing to the other when worked back and forth. Rods all were tight. No signs of hot bearings. Engine had been rebuilt by reputable
shop 800-1000 hours before this.
Its been sitting inside for 5 year, I went up and looked at it (pan is back on) and the crank smoothly turns by hand back and forth until compression builds, I didn't bump it over as
the injector lines are still on it.
I found a new mil surplus crank for 200$ but it seems really odd to break a crank. The owner openly says he's selling based on the engine being a core for rebuild. I see the
military had some trouble with the cast cranks and my understanding is the tractors all had cast cranks. Anyone run into this before?
