    4020 PTO Countershaft idler pin snapped

    What should I look for on the countershaft itself, as far as damages? It has some wear in the end from the pin rubbing into it, but everything else seems OK from what I can tell. I'm hoping I don't have to replace it too.

    4020 PTO Countershaft idler pin snapped

    That's bad news. Suppose I will have to look for a used clutch housing. So the pin ordinarily doesn't contact the countershaft? Wondering if it will be OK as it is..

    4020 Diesel Not Firing

    Lower ring in timing window is turning while cranking. The upper ring doesn't seem to have a line or anything to mark the timing which seems odd. Pulled the back cover part of the pump off, and it seems like things are moving in there. Will try to start with throttle all the way open when...
