MEP-007B Injector Pump

[Anthill]

Anyone have any experience with replacing an injector pump in a MEP-007B ? It only has 900 hours on it and it looks like the injector pump has been replaced once already. I picked this up from a municipality and they said they thought the injector pump was bad, I was able to get it to start on ether but that was it. I have not been able to find much information on removing these injector pumps. Anyone have any info on these ?

Thanks,

Ant

Is the return line plugged? on my 004 the return was plugged and would only run on starting spray. Just a thought. Have any pictures of the unit?

I will have to check the return line. Where was your line plugged ?
Unfortunately I do not have any pics yet, I will have to take some.

Thanks,

When the return line plugs on a 004, you usually have bigger problems. 99% of the time what plugs it is pieces of the governor weight retainer that is coming apart inside the IP. They will usually run a long time like that but there is a chance of the engine running away if you don't fix it.

As far as the 007, I think it has a Cat engine so it probably doesn't have a Roosa Master/Stanadyne DB pump like the 004 so I don't know.

Yes the 007b has a CAT engine, I believe it's a d3306. I have not been able to locate much info on it though.

About the only people that will service Cat IPs are Cat dealers. You may can find somebody but I know all the local shops around here won't mess with them.

I have a place lined up to rebuild it, my main issue is finding instructions on proper way to remove and replace the injector pump.

The remove and replace procedure should be in the TM. I wouldn't know where to start as I haven't ever pulled a Cat IP.

 

[Anthill]

Unfortunately the TM is not available. It's TM-5-6115-600-34 and it is not even on the pay sites. I was hoping someone had some experience with these or had the TM.

I looked it up, it's a restricted manual.

I did pull up several hits when I googled "Cat 3306 manual" through civilian sources.
