Timken KWK99300 Engine Crankshaft Repair Sleeve - Rear

Timken KWK99300 Crankshaft Repair Sleeve

Timken KWK99300 is a Kwik-Sleeve crankshaft repair sleeve for refinishing a seal-worn shaft without machining. It uses a thin stainless-steel sleeve with a hard-chromed surface to restore a smooth lip-seal contact area on rear shafts used in applications such as Chevrolet Chevette and GMC Safari service work.

Key Features

• Precision-engineered stainless steel sleeve with hard chrome finish for extended service life
• Thin-wall construction preserves the original seal size and seal lip contact geometry
• No expensive shaft preparation or machining required before installation
• Removable installation flange and dedicated installation tool help reduce sleeve distortion
• Allows installation without removing the shaft in many repair scenarios
• Part number KWK99300 for fast identification in crankshaft seal repair applications

Application Details

Use Timken KWK99300 when the sealing surface on a rear shaft is worn, grooved, or polished beyond reliable seal contact. This repair sleeve is listed for rear applications on 1976-1987 Chevrolet Chevette, 1980-1983 Chevrolet Citation, 1984-1985 Chevrolet Citation II, 1981-1982 Pontiac Acadian, 1981 Pontiac T1000, 1985-1990 Chevrolet Astro, and 1985-1990 GMC Safari. The KWK99300 is also a practical service part for manual transmission output shafts and differential pinions in these vehicles.

Common Repair Uses

• Stops seal leakage caused by a worn shaft surface
• Restores a smooth sealing track after groove wear
• Addresses recurring rear seal seepage on manual transmission output shafts
• Helps correct leakage at differential pinion sealing surfaces
• Reduces the need to replace a shaft solely because of seal wear

Installation Notes

Clean the shaft thoroughly before installation and verify the seal contact area is free of debris, burrs, and heavy scoring. The sleeve’s installation flange and tool are used to position the sleeve squarely and help limit distortion during mounting. Confirm the repair sleeve matches the shaft diameter and seal location before assembly. Part number KWK99300 should be matched to the exact rear application and shaft type before service.
