Sir Tools HO50-2 50mm Hex Head Armature for Honda Acura Crank Pulley Counter Holder

The Sir Tools HO50-2 is a 50mm hex head armature designed for use with the Sir Tools HO50 Pulley Counter Holder system. This precision-machined component is an essential part of the crankshaft pulley holding process, allowing technicians to properly secure the crankshaft pulley and harmonic balancer from rotating during removal and installation of the crank bolt.

The HO50-2 armature is engineered with a slim, low-profile hex head that slips past tight engine bay spaces and seats directly into the center slot of the crankshaft pulley. Once seated, a securing bar (sold separately, Sir Tools HO50-1 Extension Bar) slides onto the receiving end of the armature and is locked into position, providing the counter-torque leverage needed to break loose or properly torque the crank bolt.

Key Features:

• 50mm hex head designed to engage Honda and Acura crankshaft pulleys
• Slim profile seats easily into tight spaces and the center pulley slot
• Works in conjunction with the Sir Tools HO50-1 Extension Bar and HO50 Pulley Counter Holder Kit
• Prevents crankshaft and pulley rotation during crank bolt R&R
• Compatible with Honda and Acura 4-cylinder and 6-cylinder engines, 1990 and newer
• Professional-grade construction for shop use

The HO50-2 is a component replacement part for the Sir Tools HO50 and HO70 pulley counter holder systems. It is also available as part of the complete Sir Tools HO50 Pulley Counter Holder Kit for technicians who need the full system. Ideal for timing belt service, harmonic balancer replacement, and any procedure requiring secure crankshaft pulley immobilization.
