How do I prime a diesel tractor engine, after changing the filter?

Mechanic's Assistant: Sometimes things that you think will be really complicated end up being easy to fix. The Heavy Equipment Mechanic I'm going to connect you with knows all the tricks and shortcuts.

This is a utility tractor, not a truck for clarity..

Mechanic's Assistant: Are you fixing this yourself? What have you tried so far?

Had a fuel chock down on engine, so cleaned fuel filter and bowl and made sure fuel lines were clear.. Reassembled and now need to reprime sytem

Hi, let's see if we can work together to get to the root of your problem! will try my best to help!

Make and model?

You open bleed screw past the filter and use the hand pump to pump all the air out. With all the air out, the tractor should start and run.

Make - John Deere 850.
guide me here - hand pump is on the side, a grey hard bubble with a set screw above it in the body. There are two bolts at 1 oclock to this grey bubble - are these the set screws orisjust one?
Mechanic: Curtis B., Technician replied 4 years ago

Go to the injection pump, and on the inlet line, there is a bleed screw, # 3 in the diagram below. loosen this bleeder and pump the hand primer until you have all the air out, Then close the bleed screw and tractor should start and run.
