Attention: TDR Forum Junkies Hey all,
From the other other head about my injection pump, I looked at my disassembled pump this morning to find out why the shop wanted $1700 to rebuild it. No pictures yet. Keep in mind this is a Cummins reman pump I installed with Daniel Puckett in Oct. 2005. A local shop in Nashville turned up the fuel to make it 10% hot around March 2006.
* (2) rollers were worn (opposite). They explained that at Cummins, or some other time, the rollers had been replaced because they were 2 piece not 3 piece like original rollers. They showed me the difference.
* Cam plate worn from roller wear
* Advance piston stuck in housing
I believe everything else was in good condition, i. e. springs. The housing was in good condition, no major scoring, etc other than the fact that the advance piston was stuck. They believed the piston was stuck from metal from the rollers and the housing and piston would be damaged beyond reuse based on another pump they showed me. However, they did not spend any effort to separate the 2 parts.
I asked them about the delivery valves because #2 was hanging open. They said they took them apart and they slide and work fine but that one of them was hanging from metal but showed fine once disassembled.
Here's the kicker. They asked me if I had turned up the fuel because that was the most likely cause of roller wear. I said the only 2 people to adjust the pump were Cummins and you. They removed the Cummins tamper proof seals and installed their own.
What do you all think???
They planned to order a housing and piston and cam plate among other things. I talked to a shop that has housings from Bosch VE44 pumps used in the logging industry and the local shop cautioned that the piston might be different or may not fit the housing. I am going to talk to the other shop again and possibly one or two shops.
For right now I left the pump at the local shop pending a final decision on a rebuilder.
