The GM Duramax Flywheel Lock (69250) from SP Tools was designed to hold the flywheel stationary when removing or replacing the crankshaft bolt on the 6.6L Duramax diesel engines.

The crankshaft bolt is extremely tight and without a holding tool, removing the crankshaft bolt is very difficult.

The removal and replacement of the crankshaft bolt is accomplished without removing the starter motor.

The tool is simple to use: remove the inspection window cover on the transmission, slide the flywheel lock tool through the inspection window until it engages the flywheel and turn the flywheel lock tool handle to lock the tool in place.

The crankshaft bolt is now ready for removal. Works on 2001 and later 6.6L Duramax diesel trucks.
