Engine/Transmission (1998.5 - 2002) Changing Injector Pump

[KDoerr]

Good Day all. I have to Change the injector Pump in the truck and I'm wondering how hard it is and how long it takes?



Thanks Keith

My first inj pump swap took about 3 hrs. Its not that bad just be sure the keyway is at 12 o'clock on the pump shaft. And i didnt take injector lines #3,5,6 loose at the head you can push them very carefully against the block to get the pump out/in.

I took 2 days to do mine. I removed it on one saturday & then put the new one back in the next. I was not in a rush & spent about 4 hours each day. I spent a lot of time cleaning up oil from the engine compartment/undercairage (that stupid crank case vent, just pukes everywhere).



I then spent another 4 hours on a saturday replacing the front main seal & cleaning all the oil up that spilled out of the seal. Ive got back to the trans, Im gonna clean back to the trans tailshaft this weekend.

I'd say 3 to 4 hours with it being a first time changing one - really not a bad job. Just be careful as to not drop anything, especially the key, down in the gear housing.

The procedures and tools are described in TDR #51, p. 96. It should take several hours if the engine is clean and you have the tools at hand.

Not hard at all. Just take your time and be careful. When i took the lines off, I kept the isolaters on and took them off in pair. #6 line i had a stubby wrench to get it off. This will also help when you bleed the system. It took me 4 hours. Saved alot of money doing it myself. Oo. Good luck, Rick

Not to bad it took me about 3 hours a stubby 3/4 wrench does help

I didn't take 3,5,6 off either, you can push the lines aside enough to get the pump out. The only problem I had was getting the gear off the pump shaft, a little heat did the trick. The pump has an O ring that goes between it and the front cover, I had a hard time trying to push the new pump into position. What I did was used the 4 mounting nuts to walk the pump into place. I tightened each one about a 1/4 of a turn in a criss cross pattern, the book says not to use the nuts to force it in but walking did the trick just go easy.



I do have a question about barring the engine to TDC though. When you bar it over to TDC should the key way on the pump be at the 12 o'clock position? I barred mine over to TDC and my keyway was at 6 o'clock. I got lucky that the key stayed in place.

took me a total of 4-5 hours... it can be difficult to get tools into the 4 mounting bolts, but it can be done. just make sure the keyway is up, i used a mirror while turning the engine by hand.

DO NOT go to TDC the key will be at 6 o'clock. I used a small mirrior to look through the hole the breather bottle hose neck came out of.

Sorry for the delay in replying Work is nuts. Thanks for the good information I will try to get time next weekend to do the pump.



Thanks Keith

The crank turns two revolutions for every one revolution of the injection pump. If you take the injection pump nut off and the key is at 6 o'clock simply put the washer and nut back on, snug down a little (not necessary to torque) bar the engine over one revolution and VOILA! Key is at 12 o'clock.

Godspeed,
