So when it's bogging down, is it still running because the running gear is turning via the clutch engagement. If you were to push in the clutch , would the engine recover or fall flat?
Yes, either the switch is good or it's bad.My thought is if it's a fuel shut off solenoid-it wouldn't slowly die. Normally when the
solenoid take a dump-it's engine off right now. I've had those were I just cut the rod off and screw it back in to get it to the shop.
I will also run my fuel pressure gauge up where I can see it while driving.
It does have an air to air after cooler. Good suggestion about the intake hose, I had to go and look! It's a plastic molded tube from the air cleaner to the turbo inlet, doesn't look like anything that could collapse under vacuum. I'm not very savvy on how the governor or fuel rack operates so forgive me if you would. The rack is always trying to add more fuel, and the governor pushes back against it to limit fuel depending on rpm/load?
The governor can be disassembled on the truck to inspect the weights and washers but it is easier on the bench. The trick is to find someone who has had one apart then it’s not really a big deal.
Isn't there a Cat tool group for this pump?
Nothing special is required for the governor end of the pump.
