8d-7996 Sleeve Bearing Bushing — Cat 3116 3304

This sleeve bearing bushing is designed to provide a low-friction interface between rotating or sliding engine components, reducing wear and ensuring smooth operation. Manufactured to precise specifications, it offers excellent durability and wear resistance, unlike a worn bushing that can cause excessive play and noise. Operators may notice increased engine noise, particularly knocking or rattling sounds, or a loss of oil pressure if this bushing fails.

Installation & Application Notes

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.

Failure Symptoms

Early signs of bushing wear include increased clearance between moving parts, which can manifest as audible knocking or rattling noises from the engine. If left unaddressed, the wear will accelerate, potentially leading to component seizure or severe damage to the crankshaft or camshaft. Continued operation risks catastrophic internal engine failure and extensive repair costs.

Installation Tip

Ensure the housing bore is clean and free of any burrs or damage before attempting to press in the new bushing. Do not attempt to force the bushing if it does not seat properly; re-check alignment and bore condition.

Service Note

When replacing sleeve bearing bushings, always inspect the corresponding shaft for scoring, wear, or out-of-roundness.
