The retainer seal you had difficulty with we were able to get on fairly easily using outside snap ring pliers. We also placed the governor in a block of wood with a hole cut into it that we clamped down to hold the part in place while we worked on it.
I’m buying a 6.9 IDI and this video is a great help. Gives me an idea of what I’m getting into to rebuild the pump. Thanks!
Great to hear!
Great video! We're glad our kit helped with your rebuild. Be sure to let us know if we can help with any future projects.
Awesome! You guys were a big help for sure!

I see you've rebuild your pump too. I'm of the same mindset: I'd rather take the chance and try to fix it myself than pay huge money for someone else to take a crack at it. Worst case scenario, I mess it up but those mistakes are still cheaper than just forking over big wads of cash.
I figured worse case I would give it a shot!! Turned out OK
You can get the timing 180 off, but the timing lines in the window are to set your timing advance. The mounti g holes are slotted to facilitate a few degrees of advance and tdc offset
I opened UA-cam and this was the video I needed.
Great video, thanks for posting it! I’ve watched a few of these, and another builder warned not to press the head in too far into the body when you’re assembling it. He said you’d pinch the head seal 90% of the time, which might be what happened to you.
Yeah that thing was a bear. Best thing I did was figure out the size and order a 50 pack from McMaster Carr for $8
Great video! Like your attitude toward getting into the rebuild project. yes proof is if it work on the Chase.
Can't wait to see it run.
They do quality work. And they do it right they don't do it wrong because that's bad for their company I've used them many times and I thank God they can do it faster than I can with the last mistakes
Where at i need one rebuild what is the cost to rebuild one thanks?
Thank you for sharing, good teacher, i learn a lot 👍👍👍👍
I know you already know by now but as long as your pump shaft dot lines up with your dot inside of pump behind the brass bushing you should be in time.
next time I'll rebuild it thank you for you're video
Does the angled allen wrench bolt and the other one adjust fuel? Having a tough time knowing which one is which or if that's even what they do? 🤔
Quiero ver el desarmar la bomba de inyección del 310 D de Jhon Deere si posible
I don’t have access to one ☹️
All things considering you did well..👍
NECESITO UNA BOMBA DCMFC629-2LQ ROOSE MASTER..
Hey, how does the shutoff work on that injection pump? It doesn’t seem to have the internal solenoid found in the DB2 pumps on 6.2/6.5 and 6.9/7.3 diesels. Is it a mechanical shutoff?
It has a manual cable shutoff that pulls the metering valve back via the cam/lever
@@dieseJL would that top cover fit on a pickup DB2?
I rebuild my 3 time and it still leaking fuel in my crankcase. Let me know if you have that same problem just trying to find out with I'm doing wrong
No ours doesn’t leak like that. You’re probably messing up the umbrella seals or you didn’t replace the bushing. Did you watch the video where we got the dozer running and installed the pump? I covered a little of it on there. Pretty simple just gotta get the seals on that driveshaft right!!
Did the Loctite 648 work good for holding the pilot bushing in ?
It worked great! Work time is pretty short but it's definitely the right tool for the job.
I think you could also use 638.
Excellent ☘️🇮🇪👌
Enjoyed your video
Salvage workshop rebuilt an identical one a on his channel.
Nah he botched it I only works for the tyme being. But yea he had 1 apart.
I have one on a John Deere 2840 tractor waiting to add a little more horsepower by more fuel. Don’t see that there is anyway to do that!
Screw in the screw on the leaf spring to increase the plunger travel distance
@@dieseJL don’t see leaf spring anywhere?
if you do not tie the lever back the weights will fall in the pump an shaft will not go in
Weird, seems to run just fine 🤷🏻♂️
Where did you find the manual?
I think I just googled it. It should be linked in the description. Let me know if you cannot find it.
Why did you not show how the clip is attached to the throttle shaft and the o ring replacement? Mine is leaking and I am not sure how that clip is attached. Especially when trying to replace that seal while the pump is still connected to the motor
It’s really not hard, it’s kind of like an external snap ring. You just either grab it with pliers and pull up or push the long side off with a little pry bar
as to be put on a spec mechine
inj pump place needs to rebuild thay have to time the pump
