Specs At A Glance

Good To Know

Q: Does this sleeve replace my original crankshaft output? A: Yes, it is made to take the place of the original sleeve at the crankshaft output and carries the OEM cross-reference 420947573 for easy matching.

Q: Should I replace other crank parts at the same time? A: Since the driveline is already open for this sleeve, inspect bearings and seals nearby and replace anything worn so the repair holds up.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
