Injector Pump replacement

[Florida9]

I took all the lines off and the 3 screws for the injection pump for my 85 m1008 and it does not want to slide out i was thinking there might be a screw behind the water pump just wanted to make sure before i take it off

Pull the oil fill tube, and remove the bolts in the hole.

Why not read the Tech Manual?

The drive gear sits behind the front cover you have to pull the oil fill tube like Eric said to unbolt it.

 

[Barrman]

The crank shaft will have to be turned from the bottom with a large breaker bar, a mirror really helps to see the three bolts you need to remove and if you have a magnetic socket. Now is the time to use it.

Dont drop the bolts in the timing cover or your screwed, stick a rag in the hole and use a magnetic socket or dip your socket in axle greese to hold the bolts! Turn the motor over slow to get to all the bolts. Make sure you hook all the lines back up the same way they came off or your going to have a real headache. Scribe the pump and block with a line so you know where your timing is!!

I completed this a few weeks back. I have several pics in my picture album that may help.

I don't think the Humvee motor is any different in this regard. You need to slowly turn the crankshaft with a breaker bar as someone else mentioned until the bolts get to a point where you can get on them with a socket and ratchet and remove them. Once you get one off, you move the crank with your breaker bar again to get the next bolt and repeat for the 3rd bolt.

Get a 5 pound sledge hammer and a crowbar, insert the crowbar between the IP flange and the housing, then pry and hammer until the pump comes free.


































or you can look at these pics and do it the right way. remove the 3 bolts and the pump will come right out, as mentioned, you will need to rotate the crank to move the bolts on the IP to access all 3

[Florida9]

Just take your time. Use a mirror it helps. I did mine a few weeks ago. The hardest part for me was getting the intake manifold off. I don't know what they used to put it on with but I had to use my engine hoist and had the front wheels off the groung before it finally broke loose
