  • Precision-engineered steel sleeve for extended service life
  • Thin-wall design preserves the original seal size and lip-seal finish
  • Helps restore a worn crankshaft sealing surface without machining
  • Includes a removable installation flange and installation tool to reduce sleeve distortion during mounting
  • Supports installation without removing the shaft

How It Works

This crankshaft repair sleeve is used to refinish a seal-worn shaft where the front crank seal rides. By creating a smooth sealing surface, Timken 88186 helps address wear that can lead to oil leakage on Pontiac GTO, Firebird, Catalina, LeMans, Grand Prix, and Buick Century or Regal engines. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems It Can Help Solve

  • Front crankshaft oil seepage caused by a grooved seal surface
  • Seal wear from repeated contact on an uneven shaft
  • Need for crankshaft surface restoration without machining
  • Service delays when shaft removal is not practical

Installation Notes

Clean the shaft thoroughly before installation and inspect the sealing area for damage beyond normal wear. Use the supplied installation tool and flange to seat the sleeve evenly and avoid distortion. Confirm the seal lip contacts the new sleeve surface correctly before reassembly.

Quality Assurance

Timken manufactures this Kwik-Sleeve from steel for consistent fit and sealing performance in repair applications. Part number 88186 is built for front crankshaft sealing repairs on the listed Buick, Pontiac, and Oldsmobile vehicles.

This part fits 170 vehicles
