• Designed to reduce premature wear on the repaired surface
• Part number: SR3568

Product Details

The FAG SR3568 crankshaft repair sleeve is engineered to create a new sealing surface where the original shaft has been grooved, worn, or otherwise compromised. Its stainless steel construction and precise dimensions support a clean seal at the rear of the shaft, making it a direct repair option for vehicles such as the Chevrolet Silverado 1500, GMC Sierra 1500, Toyota Tundra, and Lexus GX470. This part cross-references SKF 99364 and Timken KWK99364 for the same application.

Measured specifications include a shaft diameter of 3.743 in. (95.072 mm), flange diameter of 4.035 in. (102.489 mm), width of 0.594 in. (15.088 mm), width on shaft of 0.469 in. (11.913 mm), and installation depth of 1.8 in. (45.72 mm). These dimensions help ensure the sleeve seats correctly and provides the sealing surface needed for repair.

Common Problems This Sleeve Can Address

• Oil leakage from a worn rear shaft sealing surface
• Grooves or scoring on the crankshaft or shaft journal
• Premature seal wear caused by surface damage
• Need for a repair without removing or machining the shaft
• Costly component replacement when the shaft itself is still serviceable

Installation Notes and Tips

Clean the shaft thoroughly before installation and inspect the sealing area for wear patterns, burrs, or contamination. Verify the sleeve dimensions against the shaft diameter and installation depth before pressing it into place. For best results, pair the sleeve with a seal that matches the vehicle application and confirm rear-position fitment for the specific year, make, and model.
