Given the cost of Cat rebuild kits, it isn't worth the labor time to rebuild one. We bought an
Emperor several years ago to replace one of a long line of problematic Cats (Thanks again Larry Cobb!) and ran it on one of our commercial trucks for a year. Having had no problems and having heard of no problems from others using the pump, we started specifying them for all new purchases and used them to replace any failed pump. To date we have not had to repair a single one, and don't have to special order them anymore as they are now standard equipment on the
CDS.
