Here are some responses to your questions: 1) How was installation and removal of the front glow plug? What did you have to remove from the fuel system? I assume you mean cylinder 1 (at front of tractor). This is the only one I have not changed yet. Looks like I'd need to remove the holder...

I bought a new-to-me Kubota M4500DT. The intention of this post is to show pictures (because most like to see pictures) and some insight where to source difficult to find parts for this model. I wanted to get everything working again (lights, gauges, etc.) but I wasn’t going to spend a fortune...

Where was your fluid circuit interrupted?

So when I originally tried the auxiliary hydraulics, there was some pressure there as when I bumped the lever, a stream squirted out of the faulty coupler. Since then, I drained all the hyd/tran oil and replaced with Kubota Super UDT2. I installed a brand new hyd filter screen and cleaned off...

I recently picked up a M4500DT. The 3-pt lift arms do not go up. The auxiliary hydraulics have pressure though so I suspect the hydraulic pump works. When I dropped the hydraulic filter, I did find this piece looking like a gear tooth in the bottom (see attached). I put a glow plug in the...

Thanks for the feedback. I checked the resistance on all 6 glow plugs. Only 1 was high (about 6-7 Ohms). I replaced that one and still didn't help the starting issue. Then I ended up replacing 4 more (I'll have to get to the one above the injection pump later when I remove the holder and...

Yes, I have the WSM.

Thanks for the information. On the air cock vent valve on the side of the injection pump, mine has a slow drip leak- looks like it's coming from valve to pump interface. Can I unthread this from the pump and I assume there are some copper washer seals in there?

Thanks for the information. On the air bleed valve, which way is open? Counter clockwise or clockwise? Screwed all the way in or out? Also, any idea what the normal resistance should be on one of these glow plugs?

I'm sure this topic of replacing the injection pump has already been discussed but I could not find a thread that answered all of my questions. My M4500DT is hard to start when sitting for a few days. It blows a lot of white smoke until I can get it started. I found out that 1 glow plug has a...
