View ResourcesOne of the most common Edwards RV vacuum pump repair issues is an oil leak from the motor side, coupling side, or rear shaft seal area. On Edwards RV3, RV5, RV8, and RV12 pumps, this is often caused by a worn shaft seal, a grooved shaft sleeve, or excess crankcase pressure.
The good news: in many cases, the Edwards RV shaft seal can be replaced without a complete pump teardown. This repair is usually performed from the external motor/coupling end of the pump, without removing the rotor, stator, or pumping stages.

Yes. On most Edwards RV pumps, the shaft seal repair can usually be completed as an external-end service. Typical steps include draining the oil, removing the coupling and motor-side components, removing the seal carrier or bearing housing, replacing the shaft seal, replacing the shaft sleeve if needed, and refilling the pump with fresh oil.
A complete rebuild may be recommended if the pump also has bearing noise, poor ultimate vacuum, overheating, damaged vanes, contaminated oil, or excessive internal wear.
