The Story
SKF 9663 Power Steering Pump Shaft Seal
The SKF 9663 power steering pump shaft seal is built for steering systems that need a precise sealing surface and stable fit. With a nitrile sealing surface, 0.969 shaft diameter, 1.690 outside diameter, and 0.313 width, it is sized for specific power steering pump shaft applications in classic Buick, Oldsmobile, and Pontiac vehicles.
Key Features
- Power steering pump shaft seal for steering system service
- Nitrile sealing surface type for fluid sealing applications
- 0.969 shaft diameter, 1.690 outside diameter, and 0.313 width
- Fits 1956-1957 Buick Century and Buick Roadmaster
- Fits 1956-1957 Oldsmobile 88 and 1957 Pontiac Bonneville and 1956-1957 Pontiac Catalina
- SKF part number 9663 for direct catalog lookup
Detailed Description
SKF has a long history in seal engineering, and the 9663 reflects that focus on precise design and material selection. This power steering pump shaft seal is made for applications where keeping power steering fluid contained and contaminants out is critical to steering performance. It is a direct-fit style service part for 1956-1957 Buick Century, 1956-1957 Buick Roadmaster, 1956-1957 Oldsmobile 88, 1957 Pontiac Bonneville, and 1956-1957 Pontiac Catalina. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
What It Helps Fix
- Power steering fluid leakage at the pump shaft
- Contamination entering the steering pump area
- Loss of hydraulic pressure from worn sealing surfaces
- Steering pump service issues caused by aged or hardened seals
- Fluid seepage that can leave residue around the pump housing
Installation Notes and Tips
Confirm shaft diameter, outside diameter, and seal width before installation to match the pump specification. Inspect the pump shaft and sealing bore for wear, scoring, or corrosion, since surface damage can shorten seal life. Clean the sealing area thoroughly and install the seal squarely to avoid distortion. Verify the application against your vehicle and pump configuration before ordering, especially on classic Buick, Oldsmobile, and Pontiac steering systems.
Quality Assurance
SKF manufactures seals to specific designs using premium materials and controlled production standards. The brand’s seal engineering heritage dates back to the first integrated shaft seal in 1928, and SKF seals have been used for decades in applications that require reliable fluid retention and contamination control.
