We had to take my pump out of service to replace a few things: differential cylinder rod packings and wiper seals, rock valve slewing cylinder packings and wiper, a couple boom pins and bushings, material cylinders and piston cups etc. Then we discovered that the rock slewing cyl piston/rod was shot... i wonder what else we are going to find :/

yes that is brundage orange hiding under our green! we bought this pump reconditioned in '05 from them and it was a beauty! unfortunately for me my predecessor didn't do it or me any favours by maintaining it or even cleaning it before i was hired to replace him in '08.
