Product Overview

Preventing oil leakage around the rotating crankshaft depends on the correct seal dimensions, lip orientation, and installation position. For technicians sourcing a replacement for Cummins QSK23 diesel engines, this Crankshaft Oil Seal can be matched by engine reference and part number before shipment.

When replacing this component, matching the application is more important than relying on appearance alone. Where a confirmed reference is available, the supplied part number can be used together with the engine information to check compatibility before shipment.

Why This Part Matters

This sealing component forms a barrier between the rotating crankshaft and the surrounding engine housing. Correct inside diameter, outside diameter, width, and installation direction are important because a seal that does not match the crankshaft or housing can lead to poor seating or oil leakage.

During engine repair, the crankshaft sealing surface should also be inspected for wear or damage. Some applications use different front and rear seal designs even within the same engine family, so the part number and installation position should be confirmed before purchase.
