davehummell Posted January 24, 2017 Share Posted January 24, 2017 I was offered an ape used pump to me for 1,000.00 I think the guy is to high , I am sending mine to be tested and I am told there is no repair parts for them. I may need it but I don't want to overpay. It is for a end 673. Thanks Dave Quote Link to comment https://www.bigmacktrucks.com/topic/48495-injection-pump/ Share on other sites More sharing options...

The existing parts for your pump can be rebuilt and repaired if you can find a talented guy whom takes pride in their work. It is true there are no plungers and barrels left in regular inventory but like my V8 pump, they can be rebuilt. I used a company in Mexico and they did a wonderful job on building up the plungers and barrels. I made about half of the gaskets for the pump and sourced the seals locally by size and rebuilt it myself. I then sent the reassembled pump into a calibration shop and had it calibrated for timing and fuel delivery. It cost $125.00 plus shipping to have each plunger and barrel hard chromed and lapped to correct sizing and all other parts were reused except the pins and bushings in the governor. I had the pins made from W1 steel and ground to proper size and had a custom reamer sized for the bushings. The truck, (water wagon) runs like a "scalded dog" when you get into it as it should. I have less than $1250.00 in everything all inclusive. Relatively cheap for something long obsolete. If I were looking at a pump core I'd look to give no more than $250.00 for it if it turned and didn't have plungers stuck. 1 Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

davehummell Posted February 6, 2017 Author Share Posted February 6, 2017 Thank you for the offers. I got a good pump and with the deal I got an air compressor that has the hydro pump mount and the pump and remote tank and a power steering box that was on a b model. I am really happy I found all these parts Quote Link to comment https://www.bigmacktrucks.com/topic/48495-injection-pump/#findComment-360874 Share on other sites More sharing options...
