Fitment and application details

This SKF timing cover seal 11636 is engineered for vehicles that need a precise sealing interface to retain engine oil and keep contaminants out of the timing cover area. The LongLife sealing surface type and SKF’s premium-material construction support consistent sealing where shaft diameter, outside diameter, and width must match the application exactly. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What this seal helps address

• Oil seepage at the timing cover area
• Contamination entering the sealed engine compartment
• Wear-related sealing loss at the shaft interface
• Improper seal fit from incorrect dimensions
• Service issues on Subaru Impreza, Subaru Legacy, and Porsche 911 timing cover applications

Installation notes and tips

Verify shaft diameter, outside diameter, and width before installation to confirm the seal matches the engine application. Inspect the sealing surface and surrounding components for wear, scoring, or debris before fitting SKF 11636. Clean the mating surfaces thoroughly and install the seal squarely to help maintain proper contact at the timing cover.
