Injector pump

[Mike_Pop]

Has anyone taken apart their injector pump to clean it? Is it worth doing? I had rust in mine when I pulled the top off. I just pulled the pump and found a mangled O-ring on the drive shaft. Can anyone tell me where the O-ring is supposed to go? It's on a 1984 M1009.

Thanks,

Mike, any idea how many miles are on the engine (IP)? It might be worth just getting it rebuilt. They suggest doing it every 100k or so. I think that alot of CUCV IP's are due for replacement just because of age.

Mike,

I'm trying to sell this truck. I don't want to put any more money into it than I have to. My time is limited also.

I think the pump is fine since it was working well last summer. The truck only has 49K on it.

In that case... get a brand new pump for your truck, and swap yours onto it

I need inexpensive solutions, not costly ones. I want this truck to be gone in two weeks without costing me anymore time or money.

Mike Pop,
How much moola are you asking for the 1009? Eureka is not too far from here....

 

[Mike_Pop]

Sorry...the CUCV is in NJ. But I have a bunch of trailers in Eurek that I want to sell. It's only a five hour ride from SLC. And...I will give you a place to stay and a meal. How's that for hospitality? Screw it, don't bother buying a trailer, just come out for a visit!

Do you like Moab, Mike? I plan on making a trip next spring. It would be a hoot to have you and your Mog along.

I just sold my Mog a month ago.

But, I did manage to purchase a Mighty Mite! That might be good at Moab!!! I've never wheeled there, just camped along the Colorado near Fisher Towers a few times.

Hmmm. A Mighty Mite. I have no experience with these, so bring it!

Well, I removed my injection pump and during the process, I found a bad O-ring on the driveshaft to the pump. After replacing it and reinstalling the pump, the truck fired right up and ran just fine. Unfortunately, I was lazy and didn't feel like getting a gasket for the pump to the engine block and now it is leaking. I though the old one would suffice.

In order to replace the gasket, I will have to pull the intake manifold and the injection pump off again. Oh well. Live and learn.

Photo attaced of O-ring that went bad. Since it was bad, I gave it a good scolding!
