Replacement Parts Kit For D/S Pump

The Moroso Replacement Parts Kit for D/S Pump (MPN 97650) is a complete dry sump pump rebuild solution engineered for performance engine builders and race teams who demand precision maintenance. This kit contains all essential internal components—O-rings, bearings, and front seal—required to restore a Moroso-style dry sump pump to like-new condition without full pump replacement.

Dry sump systems operate under extreme pressure and temperature cycling, causing elastomer seals and bearing surfaces to degrade over time. This rebuild kit addresses that wear directly, replacing the specific components most prone to failure: elastomeric O-rings that maintain pressure integrity, precision ball and roller bearings that manage shaft load, and the critical front seal that prevents oil weepage at the pump shaft. By isolating replacement to these high-wear items rather than replacing the entire pump assembly, rebuilders preserve costly pump housings and shafts while ensuring reliable operation in high-horsepower applications.

This kit is essential for serious engine builders maintaining Moroso dry sump systems in road race, circle track, drag racing, and performance street applications. Scheduled pump maintenance using quality rebuild kits extends system longevity and prevents mid-season failures that compromise both performance and safety. The kit's compact profile (5.45 x 7.2 x 1.15 inches) stores easily in the shop and ships quickly for turn-around service.

Moroso has earned its reputation in motorsports by manufacturing dry sump systems and support components to OEM-level tolerances. Using genuine Moroso replacement kits ensures compatibility and performance consistency across rebuild cycles, protecting your pump investment and maintaining the reliability your engine demands.
