Well it's time to bring it to the professionals or dump the dang thing. Glow plugs are ok. Re-examined internals of IP. Everything slides back and forth appropriately. Cracked line at cylinder head nearest the firewall. No luck. I just can't get a good flow. No pressure. Really not much coming out only little spurts now and then.
So guess it's time to replace the IP which may be out of my comfort zone. My question is: I know I am going to pay a $1000 dollars or so, but am I putting in another pump that might go in 225hrs (the same amount of hours on tractor now)?
Wondering if I should just sell this thing as is and put a down payment on something else....(bit frustrated).
Thanks for all your help so far.
Econ: reviewing the bidding (correct me if I'm wrong)
1. You verified voltage at the glow plugs with ignition switch both in run and cranking positions.
2. With oil fill flange removed you visually confirmed that the IP rack pin moves from a left/aft position to a right/forward position resting against the governor lever when key is switched from off to run/glow.
3. You removed the delivery valves and confirmed the internal springs and other internal parts were intact.
If all this checked out I'm stumped except there must be an internal IP problem of some sort (fuel goes in but not pumped out). It may be time to check compression for a possible non-fuel problem. Parting thoughts: check IP prices at a Bobcat dealer and save the old IP for parts. Good luck
