Update! No rust under the bolt. All three injectors where pop tested, no issues found. Pop pressure correct and no leakage when closed. I didn't have a chance to dry all of the fuel lines and pumps with brake cleaner to check for leaks, hopefully, I will do that in the next couple of...

Thank you for the advice! I will try that today or tomorrow. Then I was bleeding the system initially, the bleed screw on the injection pump was REALLY tight. I wonder if there is rust under it which does not let the copper washer to seal...

***UPDATE*** The hard starting issue was caused by the glowplugs! When I measured the voltage on each one of them I discovered that #3 had 10.2 volts as it should and then #1 and #2 had around 6 volts. Turns out there was a bad connection at the #3 glowplug which did not supply enough current...

I do have the loader blocked up when I work on it. Injector lines where bled MULTIPLE TIMES and all of the cylinders are firing properly. The engine changes the sound exactly the same when I loosen any one of the injection lines. The smoke clears completely once the engine is warm, it is...

No difference at all. Smokes just as bad since the governor holds the fuel rack in the open position. Tried starting it at idle, there is less smoke, but it takes quite a bit more cranking.

I will check the resistance tomorrow and report back. I did visual check the glowplugs while they were in the cylinder head when I removed the injectors. They were clearly visible through the injector ports. It took them about 20-25 seconds to get bright red (with the ignition key in the...

Here is a video of it starting up. I never knew that the glow plugs are also on while the ignition switch is in the crank position! I will check that out tomorrow! https://www.youtube.com/watch?v=kiPZv-TrgV4

I have removed the cover from the side of the injection pump, and the fuel rack is moving freely without binding. The only thing that I noticed is that when I rapidly push on the throttle lever (from slow idle to full with the engine shut off), the governor does not move the fuel rack very...

Yes, it always started very well. Unfurtunently, I don't have a diesel compression tester, but I doubt that its an issue since in the fall when it was warm, it would start even without glowplugs. Yes, there is a removable cover on the side of the block where the injection pump mounts. I will...

Hello everyone, I am new to this forum! Back in September, I purchased an early Kubota B7100 (manual-shift) tractor with a couple of issues. Unfortunately, it does not have an hour meter and it does look like the machine was well used judging by the original front AG tires which have about...
