My Dad was a pumpman for twenty some years before he died. I too worked pumps with him as a kid and then fulltime for twelve years until I went fulltime Active Guard and Reserve in 1983. We sold Meyers and Jacuzzi pumps and tried to keep spare parts on hand. For quickest turn times for dairies and feedlots, retaurants, etc we would even rob new pumps of their cases if need be. Much cheaper than another new pump and was the preferred method. Try your dealer for this option. We used to save many cases though as the others have said by drilling and tapping the ends of the crack(s) for a quarter inch bolt, inserting the bolts, grinding down heads and veeing the crack out. Preheat the casting, flux well and braze with brass rod. Depending on your particular pump and the location of the crack it is probably better to dis-assemble the casing. Disa-assembly allows better access and handling and it also prevents melting the common plastic and rubber parts in newer pumps. Obviously due to some breaks extending through machined mating surfaces, some cracks were beyond repair. We also sometimes used the same preparation with a two part epoxy then known as Cold Weld or Epcoweld. It was similar to some of the epoxys currently available. PS Remember to clean any corrosion or other foreign matter from the case and fittings or you may have problems with FOD plugging your injector's venturi nozzle.

But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
