Ok was playing yesterday I was wot when my truck stalled and turned off. Went to start it and the shaft seemed jammed. Took the glow plug out still nothing. I thought maybe the one way bearing was gummed up. I removed the backplate only to find this. What do ya guys think? Would I be better of just replacing the motor or should I repair it. The crank case looks good. For sure I would need sleeve and piston. I haven't removed the crank yet to check it or to see if any damage was done to that area of the crank case. TIA.
