240d;

Does anybody know a shop that rebuilds these pumps? Not just a shop that will give it a try, but one with a good rep for doing them correctly? Already have one that was rebuilt at less than 120k and its shot. Of course one wonders why it was rebuilt at such low mileage because we all know how bulletproof these are supposed to be.

I used Southwest Diesel and Electrical in Phoenix for quite a few Cummins engine injection pump rebuilds. Never had a problem. They were pricey but results mattered more to me than cost. I don't remember if I ever had a Mercedes pump rebuilt by them.

Shyte fuel and inadequate filtration are the usual culprits when it comes to injection pump failure. This ULSD we get in AZ is a killer on our older cars.

Well, I brought an injection pump from an OM603 to Southwest Diesel & Electrical in Phoenix and wanted them to hook it up onto their Bosch testing station (which they proudly advertise on their website as being one of the only shops left with the Bosch testing station) for a free diagnostic.

When I returned, the injection pump was in pieces in a box. I asked them why they took it apart, and they said it was bad. I asked them why it was bad, and the person at the counter said, "I don't know, it's just bad. That will be $100."

I asked why it was taken apart when I specifically wanted it put on the Bosch test station. Their answer was, "Oh, we got rid of that equipment a long time ago. We had to take it apart to see if it was good or bad." So, I had to pay $100 for a pump I brought in for someone else because I wanted to have it tested, and it came back totally useless.

Also, I had the injectors in my 300SD rebuilt there. As I recall, three of them leaked between the upper and lower halves, so they had to redo them. Then one of them still leaked and the technician told me that it was my hard lines or the rubber return hoses leaking, which I knew it wasn't.

I had to get pushy in order to get them to fix it. When they split the injector halves, I could see why it was leaking--there was a lot of scale they hadn't cleaned and the technician bead blasted if off. After that, it didn't leak.

I also didn't like the technician saying, "Pop pressures don't really matter on these old injectors." They also wanted about $70 each for heat shields that I can get online for $2 each. So, if you use them, don't let them take you for a sucker.

Well shoot. Scratch off another rebuild shop. It's been quite awhile since I had some work done by them and it sounds as though their personnel and quality of their work has gone by the wayside. Sorry for the bad experience you got from them but thanks for the update.

I think that is the shop that did the rebuild before I purchased the car. Didnt last very long. Poor running and oil migration into the fuel.

Lots of shops around will service injection pumps, cummins, stanadyne, cat etc. I dont really want billy-bob thinking they're all the same and disassembling mine. Prefer a shop that has a history of bosch/mercedes work.

I think Southwest Diesel & Electrical quoted $2,000 to rebuild the six cylinder OM603 injection pump. I know they aren't cheap to rebuild anyway, but that's insane. Might as well send in the pump to Dieselmeken or Myna for that money.

One of the employees did have a nice 190D ponton in their shop, not that it means anything, but it was neat to look at.

These injection pumps should last hundreds of thousands of miles before having problems, so I imagine a failing pump would either be caused by a poor rebuild (maybe someone had it done as preventative maintenance), poor quality fuel (coagulated waste vegetable oil), lack of fuel filtration, or frequently running the tank empty.

What's also interesting is that I brought them in a set of injectors that I had removed from a wrecking yard car, which looked like they had been freshly rebuilt and they even had the little rubber bands with the painted numbers on them. When I had them tested, they said that they were bad. I asked how bad they were, and they just said that they were bad and couldn't tell me any more than that.

Scammers in that situation. Or just brainless. Without the gear it would be impossible to recalibrate it after a rebuild. They would have known this. Why they even took it apart mystifies me.

Mentioned on this thread and something I will think about. Adding lubrication to the fuel is perhaps something we should really think about.

These old inline injection pumps are pretty durable. Unless abused in some way. At least up to the reasonable expected lifespan of these cars. Even then many if not most of these cars are not scrapped. For the pump being bad.

There are two places that should be able to rebuild a Mercedes Bosch M or MW injection pump in the US well.

First choice would be Becs Pacific in Whittier, CA.

Second would be Diesel Injection Systems in Santa Maria, CA.

A passable place, they have all the Bosch test and repair equipements but it's run by a middle aged Woman who's no lady and blows hot or cold from one moment to the next .

They've done some injectors for me after I got worthless ones and the Okey-Doke from a forum member here, they seem O.K. so far .

I also asked them to rebuild my injection pumps because I know for a fact that it had water, rust, fungus and filthy fuels run through it by the DPO of my car, they charged me $500 and said 'it only needed calibration on the machine" ~ I've not yet the heart to install it and see if it's actually any better .

Some place up in San Fransisco is supposed to be really good, they did the I.P. and injectors for my 240D and it runs sweet as can be ~ no smoke ever but the fuel mileage isn't what is used to be and rarely exceeds 25 MPG since the rebuild .

I know of a couple of fellow dieseler's that had their injection pump rebuilt by them and both instances they were not happy with their work. I am not sure about their quality lately as they were highly recommended some time ago.

Another outfit that I heard good reviews is this place up far northern, CA.

I had that place replace the diaphragm on a 200D injection pump and calibrate it, and then rebuild four injectors. The total cost was $171.75 for all the work and I provided new nozzles. It seemed a good job was done.

However, I later sent them five injectors for an OM617 and I think three of them leaked, but they refunded my money without a hassle.

Are you referring to the place in South San Fran or Fuel Injection Center in Shingletown, CA?

I worked there for 6 Months as a Temp Employee while their regular Employee was in the Hospital and recovering.

I only dealt with the Husband (he married into Money as was said his Wife owned the place) and he was OK but I don't think he knew how to do much of the work there.

The other employees were competent. They had at least 4 test stands that could have run a Mercedes type pump on them but that was around 1989.

I was stuck in the area that did the Stanydyne/Roosamaster type Pumps for Ford and Chevy Diesels and did not pay attention to what the one guy they had that did the Inline Fuel Injection Pumps.

That company had been in business since the 1970's. They has a lot of business back then and likely still do.

I want to make a general comment on Fuel Injection Shops and the flexiable term rebuilt.
The small privatly owned shop where if someone said they wanted the Pumpl rebuilt we did not test it but tore it down and inspected the parts. On inline pumps we routinely replaced the tappet roller, the busning, and the Pin. Camshafts had to be really bad for them to be replaced. The Elements (plungers and barrels) would not be rejected unless there was obvious issues. Replacing few parts was done for the customer to keep the cost down.

When the Pump was tested if the Elemets (plungers and barrels) did not pass then they were replaced after the Customer authorized that.

The next shop I worked in aparenlty had a deal with International dealer as we did a lot of their 8 cylinder inline fuel injection Pumps (Bosch). At that shop the pumps always got new Elements (plungers and barrels) and rollers, pins, and bushings and if anything was even slightly questionable it got replaced. But those Fuel Injection Pumps were going to the International Dealer where the Customer would exchange them so they got top dollar and a top warranty.

The other issue is one that is not well known. Very people know how to rebuild inline fuel injection pumps; especially of the various companies and types.

That also applied to myself. I only knew what my Boss taught me and I don't even know if he ever know how to do the complete job. We in fact did not have all of the tools do the job and the (Robert) Bosch instructions on the Film Fisch were extremely sketchy.

When I got to the 2nd Fuel Injection Shop that did stuff in a more professional manner I was at a loss as there was tools and gauges that I was expected to use that I had never scene before.

The only people I met from the other Fuel Injection Shops that knew the complete jobs were from Europe or the UK. In Europe you sort of go through a apprenticeship program.
There is not alot of Eropeans or people from England that immigrate to the US.

Also working in a Fuel Injection Shop does not pay as well as being a regular Diesel Mechanic and as it often is low paid people have low skill levels.

You can go to a Trade School and take Diesel Mechanics but locally there is no place you can go to learn to rebuild all kinds of Fuel Injection Pumps the way the maker wants them rebuilt.

Cool. I heard Jerry was a fair person. Even recommended/farmed out to other shops if he isn't capable of doing the work.
