Product Details

SKF 37825 is engineered as a rear crankshaft seal for Porsche 924 models from 1977 through 1982. SKF has a long history in seal design and manufacturing, and this seal follows that approach with premium materials selected for the demands of engine sealing. The listed dimensions help ensure the seal seats correctly, maintains contact at the shaft, and supports reliable oil control at the rear of the crankshaft. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Rear main seal oil leakage
• Oil seepage around the crankshaft area
• Contamination entering the engine sealing zone
• Seal wear from age and heat exposure
• Loss of proper crankcase oil retention

Installation Notes and Tips

Confirm the shaft diameter, outside diameter, and width against the original seal before installation. Inspect the crankshaft sealing surface for grooves, scoring, or contamination, and clean the housing thoroughly before fitting the new seal. For Porsche 924 rear crankshaft seal service, correct orientation and careful seating are important to avoid premature leakage. SKF 37825 should be installed only after verifying the vehicle application and seal dimensions.

Quality Assurance

SKF manufactures seals to defined specifications using materials selected for the operating environment. The brand’s seal engineering background and long production history support consistent fit and sealing performance for engine applications such as the Porsche 924 rear crankshaft seal.
