Not to jump on anyone’s toes, but here’s how mine connects.

🍿 You got this!

Let us know if the seal kit works. I kept my Kubota OEM controller and thought about fixing it and selling it.

I just replaced mine with Prince MB21BB5C1 Directional Control Valve, Monoblock, Cast Iron, 2 Spool, 4 Ways, 3 Positions, Double Acting Cylinder Spool, Spring Center, Straight. It’s rated at 8 gpm and included the power beyond plug adapter. On Amazon for $175 with shipping. Make sure you get...

I recently replaced my stock control valve with an aftermarket unit. The stock unit functioned, but leaked. I am thinking about rebuilding it and selling it. Is there a market for this OEM unit?

Here’s how I tackled my injection pump…. Laminated and studied a copy of the injection pump parts schematic before hand. I snapped lots of before, during and after photos. I counted the number of threads needed to remove everything related to the pump assembly. Thoroughly cleaned the area...

I will get that posted this week.

I agree, it’s not just “let's take it apart and toss it backtogether kinda of thing”. That would be foolish. As I said, I was extremely anal about the process. I don’t have the equipment to accurately measure the flow rates, but a pre and post fountain test shows vast improvements. Before...

If my tractor was used to make $$, I would definitely let the pros handle. When I owned my business, I never touched any of the vehicles…they all went to the shop.

A microscope…now that’s getting detailed!

“It takes half your life before you discover life is a do-it-yourself project” a quote by Napoleon Hill. No offense intended, but why are so many fearful of taking a 750D injection pump apart? It’s not rocket science; understand your limitations. You need to be careful, meticulous, take...

$850 is for a rebuild with calibration, kinda worst case $$. I stopped the leaking by cleaning the parts in my ultrasonic cleaner and installing new gaskets and o rings. It fountains better now too. Before disassembly, each valve would discharge less than an inch high, now they squirt about 5...

Thank you for your reply and no offense taken. Every situation and the decision to DIY or let the pros handle it is different. In this case, I have the time, the tractor isn’t used for income purposes and having it function immediately isn’t necessary. I spoke to my local shop. They would...

Thank you for the reply. I found some great videos and the pump is working now. It wasn’t very difficult getting it to function. And you’re correct about other parts needing attention. I ordered a few parts that should arrive this weekend 🤞. I will let you know if I need to talk parts.

THANKS!

Thank you for the reply! I need to slow down and read my WSM in detail!

Thank you for the reply. Sounds like I need to pull the head shim. Stupid mistake by me. I got in a hurry and looked at the WSM pictures and skipped the text. I tried to follow the EOIC valve adjustment method. When the exhaust is starting to open, set the intake. I think this exhaust...

Thank you for the reply. I'll check the oil for fuel. Hopefully, what little amount of times I cranked it, it will be obvious. Aside from the injection pump, the valve train is the only assembly that I adjusted. Any comments on how I adjusted the valves? Or the missing head shim? I'm just...

Thank you for your reply. You're right about "should be worked on by pump shops". But when shops don't answer the phone or respond, it's not an option. For what it's worth, I was very methodical when removing and replacing the injection pump assembly. I even torqued the barrels to the...

Thank you for your reply. Yes, each valve had a shim and I reinstalled them exactly as I found them. I removed the new gasket. That appeared to help the fountain height. I also reinstalled them to the same torque as when I removed them. But it's certainly something I can adjust.
