Timken 222450 Power Steering Pump Shaft Seal

Timken 222450 Power Steering Pump Shaft Seal

The Timken 222450 power steering pump shaft seal is built for steering systems that need a precise seal at the pump shaft. It is a direct-fit sealing component for select Toyota applications, including Toyota 4Runner, Toyota Van, Toyota Pickup, and Toyota Land Cruiser models.

Key Features

• S-Nitrile material for oil and grease sealing performance
• Reinforced outer case helps resist installation damage
• Ribbed rubber inner diameter supports sealing on minor spindle imperfections
• Internal contamination exclusion system helps block debris that can lead to leakage
• Vent holes promote lubricant flow around the seal lip to reduce heat build-up
• Outside diameter: 1.702 in. / 43.23 mm
• Shaft diameter: 0.945 in. / 24.00 mm
• Housing bore: 1.693 in. / 43.00 mm
• Width: 0.315 in. / 8.00 mm

Detailed Description

Timken 222450 is a power steering pump shaft seal engineered to retain lubricant at the shaft interface while helping keep contaminants out of the steering system. The S-Nitrile sealing material is paired with a reinforced outer case and a ribbed inner diameter to improve seating and sealing consistency on the pump shaft. Vent holes help circulate lubricant around the seal lip, which supports cooler operation at the sealing surface. This part cross-references Timken (e.g., 222450) for the same application.

Compatible With Toyota 4Runner, 1985-1989; Toyota Van, 1984-1989; Toyota Pickup, 1980-1988; and Toyota Land Cruiser, 1980-1987. For Toyota 4Runner and Toyota Pickup steering service, the Timken 222450 seal provides the dimensional fit needed for pump shaft sealing in these applications.

What It Helps Address

• Power steering fluid leakage at the pump shaft
• Contamination entering the steering pump sealing area
• Seal wear caused by heat build-up around the lip
• Poor sealing on shafts with minor surface imperfections
• Damage during seal installation

Installation Notes and Tips

Verify shaft diameter, housing bore, outside diameter, and width before installation. Clean the pump bore and shaft thoroughly, and inspect the shaft surface for scoring or wear before pressing in the seal. Install the seal squarely to avoid distortion of the outer case and sealing lip. Confirm the application against the vehicle year and model before service.

Quality Assurance

Timken oil and grease seals are built with precision sealing designs and contamination control features to support reliable steering system service. The Timken 222450 part number is used for the listed Toyota applications and should be matched to the vehicle’s steering pump dimensions during repair.
