Timken 712010 Engine Crankshaft Seal - Front or Rear

Timken 712010 Engine Crankshaft Seal

Timken 712010 is an engine crankshaft seal built for controlled lubrication and contamination control at the sealing surface. It is a direct-fit option for select Mazda applications, including Mazda RX-7 rear differential use and front-position Mazda B2000 and Mazda 626 applications.

Key Features

• Vent holes promote lubricant flow around the seal lip to reduce heat build-up
• Precision sealing design helps retain oil and grease while blocking contaminants
• Reinforced outer case resists installation damage and adds durability
• Ribbed rubber inner diameter helps seal minor spindle imperfections and supports positive seating
• Internal contamination exclusion system helps keep debris out of the sealing area

Detailed Description

Timken 712010 is engineered for applications that need stable sealing performance under heat, rotation, and exposure to road contamination. The vented design helps move lubricant around the lip area, while the reinforced case and ribbed inner diameter support a secure fit on the shaft or spindle surface. For buyers searching for a Mazda RX-7 rear seal or a front seal for Mazda B2000 and Mazda 626, this part number provides a focused replacement option. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Oil seepage at the crankshaft or seal interface
• Grease loss from a worn sealing surface
• Contamination entering the sealing area
• Heat-related seal wear from poor lubricant circulation
• Leakage caused by minor shaft or spindle imperfections

Installation Notes and Tips

Verify the seal position before installation: Fits 1987-1991 Mazda RX-7, rear, non locking differential; Fits 1980-1984 Mazda B2000, front; Fits 1980-1982 Mazda 626, front. Inspect the shaft or spindle for scoring, corrosion, or burrs before pressing the seal into place. Clean the sealing surface thoroughly and seat the seal evenly to avoid case distortion. Use the correct installation method for the application so the lip is not rolled or damaged during assembly.

Quality Assurance

Timken oil and grease seals use precision sealing geometry, a reinforced outer case, and contamination exclusion features to support consistent service performance in the listed Mazda applications.
