GM Saginaw Power Steering Pump Double-Groove Aluminum Pulley - Black

• Supports steady hydraulic assist in compatible GM Saginaw-style steering systems.

• Designed to maintain consistent fluid pressure for smooth steering response.

• Durable pump construction helps support long-term steering system reliability.

• Compatible with GM Saginaw-style power steering pump applications.

This black aluminum double-groove pulley is built for GM Saginaw-style power steering pumps using a 5/8" keyway shaft. It bolts onto the pump's keyed shaft and provides two V-belt grooves, so it can drive the power steering pump and one additional accessory — such as an alternator — off a single belt run.

This pulley is a keyway-attachment part only. It is not compatible with press-on/press-fit pump shafts found on later Saginaw pumps. Confirm your pump has a keyed shaft (common on Saginaw P-series pumps from roughly 1964–1974) before ordering, since the two shaft styles are not interchangeable.

Hardware is not included and the pulley is sold individually. Outside diameter is 5.750", with a standard V-belt profile designed to match factory and aftermarket keyway-shaft Saginaw pump applications.

Applications
Fits GM Saginaw-style power steering pumps with a 5/8" keyway shaft, commonly found on GM vehicles from roughly 1964–1974, including Camaro, Chevelle, Nova, C10, and GMC C/K trucks equipped with this pump style.

Installation
Slides onto the pump's keyed shaft and is secured with a retaining nut (hardware not included). Confirm pulley offset and belt alignment against your accessory drive setup before installation, since bracket and pump spacing vary by application.

Shaft Compatibility
Keyway attachment only. Press-on/press-fit shaft pumps (common from the mid-1970s onward) require a press-on pulley and are not compatible with this part.

Will this pulley fit my power steering pump?
This pulley fits power steering pumps with a 5/8-inch keyway shaft. It is not compatible with pumps that use a press-on or press-fit shaft.

How do I tell if my pump has a keyway or press-on shaft?
A keyway-shaft pump has a visible keyway slot machined into the exposed shaft and is commonly found on Saginaw power steering pumps used through the mid-1970s. Press-on shaft pumps have a smooth shaft with no visible keyway and require a press-fit pulley.

Can this pulley drive two accessories off one belt?
Yes. This double-groove pulley is designed to drive the power steering pump and one additional accessory, such as an alternator, using two V-belts.

Does this pulley include mounting hardware?
No. The retaining nut and mounting hardware are not included and must be obtained separately.

Will this work with an underdrive or overdrive pulley setup?
No. This pulley is designed with a standard drive ratio and is not intended for underdrive or overdrive pulley systems.

Is this pulley steel or aluminum?
This pulley is manufactured from lightweight aluminum and features a satin finish. Compared to a traditional steel pulley, aluminum helps reduce rotating weight while providing corrosion resistance.
