This is a rear crankshaft seal kit for Cummins 4B, 6B, ISB, and QSB diesel engines.

It includes a wear ring (Speedi-Sleeve) and installation tools to replace a leaking rear main seal without pulling the crankshaft. The kit restores oil-tight sealing, stopping leaks between the engine and transmission. Replace it when oil drips appear at the flywheel housing to prevent damage to the clutch or starter.
