“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.

Thank you for your reply. Yes, each valve had a shim and I reinstalled them exactly as I found them. I originally did put a gasket on, but later removed it.

Long story short, I replaced my clutch. While apart, I pulled the motor and installed a few gaskets, removed carbon on valves & cylinder tops, replaced valve seals, and set valve clearance 0.008”. I also ended up dis-assembling the injection pump and running parts through my ultrasonic...

I came across your post a while ago, after my pressure plate lost a "finger". Glad to hear your tractor is running! The finger seized EVERYTHING up instantly...it was lodged between the "bellhousing" and flywheel. This was my first time working on a tractor. I ended up removing the engine...

Well it’s definitely corroded inside the injection pump body, just enough to stick two delivery valves and the control rack. I got everything apart without damages and they are going into my sonic parts cleaner. Might need input on how to orient plungers/delivery valves vs the control rack...

Thank you for your reply. I cranked it for a while, about 10-15 seconds several times over. Continued this after one delivery valve had some fuel bubbling out. Nothing ever flowed out of the other two delivery valves. I removed the pump body this evening. I found the two dry delivery valve...

Absolutely zero fuel is discharging from the rear most two injection pump delivery valves. The forward-most valve just kinda bubbles out. Is valve clearance related to the injection pump? Maybe I errored when I adjusted the valves. When an exhaust valve pushrod started to raise, I set the...

I finally got back working on this. I pulled the motor and the head and looked everything over. Sleeves and pistons look great. My gasket kit came with valve stem seals, so I will check if the valves need lapped (NOT with a drill). I will set the valve clearance at 0.008" as you said. The...

I have the clutch housing exposed and clean. How are the throw out bearing, holder and input shaft removed? I removed the a pin at the other end of the shaft, but now what? I plan on replacing the front seals too.

I was trying to find out why my 750d engine seized. In the process, I removed the head cover, push rods, rockers, and head. Everything was fine. The weather was turning bad so I quickly put the head and cover on, finger tight, but not the push rods or rocker. Next day, I split the tractor...

Thx! And I split it without removing the loader. I lowered the bucket and placed jack stands under the loader frame (near the foot pads). Removed the required stuff, slid a floor jack under the rear “cross member”, removed the frame bolts, and pushed/wiggled the rear half backwards….took...
