Engine Rear Main Bearing Seal Set

The Fel-Pro BS40433 kit provides the seals required to service the rear main bearing journal on compatible engines. It is intended for technicians and DIY mechanics performing a rear main seal replacement during engine rebuilds or transmission removal jobs.

Seal Replacement Constraints

Successful installation depends on correct crankshaft surface condition and alignment during assembly. The transparent colour allows visual inspection of the sealing lip before fitment. No installation tool or alignment sleeve is included in the package.

Upgrade From Worn Original Seals

This set replaces factory seals that have hardened, leaked or been damaged during prior service. The jump is justified when the engine is already disassembled for clutch, transmission or crankshaft work and the original seal shows any sign of weeping.
