Save time and frustration when servicing Honda crank pulleys with the Powerbuilt 50 MM Crank Pulley Holder. This tool is designed to fit and hold most Honda and Acura engines with a 50mm diameter and hexagonal crankshaft pulley. Place the pulley holder in the center hole of the crankshaft pulley, use a 1/2-inch drive extension and breaker bar to hold the pulley preventing the engine from turning.

The Powerbuilt Honda 50 MM Crank Pulley Holder is made of tough chrome molybdenum with a manganese phosphate coating for strength and durability.
