Hey everyone I was working on my recent purchase of a M7950dt loader tractor. I bought it not running which i dont know if it was the best move pretty sure I bumped my head. I checked the engine oil and changed the filter. I skipped the sediment bowl and the main fuel tank. I ran a new line from the diesel can to the primer bulb. I changed the fuel filter and I got the fuel filter and injection pump bled and primed. I have fuel at the injectors bled the air to that point. Tractor to my knowledge has sat alittle while. New battery and new battery wires both (2/0).
It just cranks Does not fire. Gave it a small wiff of ether very small and nothing. Took glowplugs out and tested them they are bad. Tip to tip and nothing happens on my meter.
Does the tractor really need the glow plugs that much to start??? Am I to think the engine is really that worn out to start?? 6k hrs on it.
Injection pump CAV looks to be new. Its nicely painted up with green dots like it was checked off at assembly.
I did a test with the glowplugs out. Checked the very first cylinder for compression closest to the rad. This was a dry test I got 220. Next one in I got 150. The last 2 I have not checked yet. A friend of mine thinks the rings could be stuck from sitting I put some trans fluid down in the glowplugs holes to get the rings to let go. A couple days of that im going to slowly bump start that fluid out of the holes and do a wet compression test with the gauge again.
What do you guys think so far???
