Rear Main Seal Set BS40183
This Fel-Pro rear main seal set is designed for engine rebuilds where the crankshaft rear seal must be replaced. It suits professional technicians and experienced DIY mechanics performing bottom-end work on compatible applications. The transparent colour helps confirm correct seating during installation.
Verify crankshaft rear seal dimensions before
Confirm that the engine block and crankshaft journal match the seal profile required for this BS40183 kit. Check for existing wear or groove damage on the sealing surface that could prevent a proper fit. Ensure the correct installation tool is available to avoid distorting the new seal.
Performs under continuous engine heat and vibration
The seal maintains its integrity through repeated thermal cycles and sustained crankshaft rotation. It resists extrusion and hardening during extended operation at normal operating temperatures. Durability is consistent across long service intervals rather than only during initial break-in.
