Edwards RV Shaft Seal Replacement
Oil leaking near the motor side, coupling side, or rear shaft seal area is one of the most common Edwards RV pump service issues. In many cases, the shaft seal can be replaced without a full pump teardown.
If the shaft sleeve is grooved, polished, scored, or worn, replacing only the shaft seal may not stop the leak. For best results, inspect and replace the shaft sleeve during the repair.
