OEMTOOLS 25557 Flywheel Locking Tool

The OEMTOOLS Flywheel Locking Tool locks the flywheel in place when removing harmonic balancer on 6.6L Duramax engines with Allison Automatic Transmissions. Using this tool will save you time by securing the flywheel at the transmission as an alternative to having to remove the starter for water pump replacement. The 36 mm 12-Point Socket with 3/4 square drive should be used to remove harmonic balancer bolt and retorque on installation. The toothed pieces with screws are compatible with Duramax 4500 / 5500 trucks.
