This sleeve bearing is a crucial wear component within the engine's rotating assembly, designed to reduce friction between moving parts like crankshafts and connecting rods. Manufactured to meet OEM quality, it provides a durable bearing surface that prevents premature wear on more expensive components, unlike a worn bearing which can lead to excessive play and oil pressure loss. Operators may notice increased engine noise, particularly knocking sounds, and a drop in oil pressure when a sleeve bearing fails.
Always verify with serial number before ordering.

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The first indication of a failing sleeve bearing is often an increase in engine noise, such as a distinct knocking sound from the bottom end. If ignored, this can progress to significant crankshaft and connecting rod journal damage due to metal-on-metal contact. Continued operation risks severe engine damage and costly repairs.
Ensure the crankshaft journals and bearing surfaces are meticulously clean and free of any debris before installation. Do not use abrasive materials to clean the bearing surfaces, as this can damage their precision finish.
Inspect the crankshaft journals for scoring or wear when replacing sleeve bearings, as damage to the shaft will necessitate its replacement or machining.
