Your cart is empty. Nice Locking tool:
Lock flywheel in place when removing harmonic balancer on 6.6l duramax engines with Allison automatic transmissions.
Superior material:
Made of CRV steel, which is heavy duty and is able to anti-rust and resist corrosion, ensure an unparalleled long term trouble-free service.
Easier work:
This tool slips into place under an easily removable inspection plate. Worked great at holding the engine solid while loosened (and tightened) the crank pulley on duramax（nearly 300 ft-lbs tight.）
How to use:
Toothed pieces only----Work with Duramax 2500 / 3500 pickups .Remove metal spring-loaded inspection plate on the bottom of the transmission. Tool should slide into opening toward engine with the top of the tool engaging the teeth of the flywheel.
Toothed pieces with screws---- Work with Duramax 4500 / 5500 trucks.Remove the rubber inspection cap on the bottom of the transmission.Insert the tool at the front of the opening to engage the flywheel and hand tighten bolt to hold tool in place.
Forged 36mm socket----- Remove harmonic balancer bolt and re-torque on installation. 36mm 12 point socket can also be used on axle.

Came earlier then anticipated, seems to be of high quality, I'll update when I get my water pump installed and let you know how it worked, but from all the reviews I don't expect any issues with it! Would highly recommend! Best wishes to all that need or use this product! Thanks. Update, July 23 2024, Worked as it should did the job; to bad I put the harmonic balancer on backwards, so it did it twice!!! YEESH!!!!

This a must have for a LLY duramax, make sure you have a 3/4” prybar for the 36mm you will need it!

Tool worked perfectly for my water pump replacement. I was surprised the socket didn’t explode on how tight the crank bolt was.
