Hello! Let's see if we can work together and come to a satisfactory conclusion!

Jumped timing, as in injection pump timing? This model would have a keyed drive shaft for the injection pump, and unless the key sheared, would not get out of time. What is happening with tractor? Won't start? I there smoke from exhaust when cranking?

Customer: replied 1 month ago.
Won't start. Turns over good. Timing marks crankshaft gears don't line up.

Gear train timing has not changed. You just have to make multiple turns until all the marks will align. How does tractor kill? With key or with pull cable?

Don't charge me anything. You did nothing.

If you loosen the high pressure fuel lines at the cylinder head and crank, do you get any fuel spraying? No just dribbling?

Did you find engine out of time?
