18499 Bearing | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta bearing is a precision bearing component engineered to support a rotating clutch, shaft or coupling used in the engine clutch and elastic-coupling support. It is manufactured to the original Volvo Penta dimensional, material and interface requirements so the serviced assembly retains its designed alignment, sealing, load capacity and operating reliability. In service, it supports the clutch or elastic-coupling rotating member and controls radial movement between engine and driven equipment. Selection must be confirmed by OEM part number 18499, the exact engine or product model, serial number and installed configuration.

🚤 Compatibility

• Engine Family: TWD, TID, TD, D, TAD

🔌 Function

Supports the clutch or elastic-coupling rotating member and controls radial movement between engine and driven equipment. Inspect the shaft, housing and lubricant supply, then install with the correct tools and specified clearance or preload.

⚠️ Common Signs of Failure

• Rumbling or growling noise under load
• Pitting, flaking or scoring of the running surfaces
• Heat discolouration of the races
• Shaft play, run-out or vibration
• Metal particles in the oil

🛠️ Service Notes

• Keep the bearing wrapped until you fit it and work clean — dirt trapped in at assembly is a leading cause of early failure
• Inspect the shaft and housing seats for wear, scoring and burrs; a new bearing in a worn seat only repeats the failure
• Press or drive squarely on the race being fitted, using a drift or tube that contacts the ring face fully, so the load never passes through the balls, rollers or bearing surface; never strike the bearing itself
• Lubricate with the grade specified for that assembly, and where the bearing takes an adjustable preload or endfloat, set it by the workshop manual procedure rather than by feel
• Renew the adjacent seal whenever a bearing is replaced — access is already open, and a failed seal is often what killed the bearing
