181538 Ball Bearing | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta ball bearing is a precision rolling-element or raceway component used in the legacy Volvo Penta ball-bearing position. It is manufactured to the original Volvo dimensional, material and interface requirements so the serviced assembly retains its designed alignment, sealing, load capacity and operating reliability. Inventory cross-reference associates this service number with standard 6210 bearing geometry; verify clearance, shielding and lubrication specification before substitution. In service, it supports a rotating shaft with low friction while controlling radial load and limited axial load. Selection must be confirmed by OEM part number 181538, the exact engine/product model, serial number and installed configuration.

🔌 Function

Supports a rotating shaft with low friction while controlling radial load and limited axial load. Measure shaft and housing fits, renew contaminated lubricant and related seals, and install using force only through the race being fitted. Set preload or end float to the applicable Volvo Penta specification.

⚠️ Common Signs of Failure

• Rumbling or growling that follows shaft speed
• Play or run-out at the shaft
• Roughness or catching when turned by hand
• Bearing housing hot to the touch after running
• Metallic debris in the oil

🛠️ Service Notes

• Work clean — leave the bearing in its wrapping until the moment it goes in, and do not wash the preservative out or blow it dry with compressed air
• Apply the fitting force only to the ring being fitted, through a tube or drift that bears on that ring alone; force pushed through the balls from one ring to the other dents the raceways and the bearing will be noisy and short-lived from the first run
• Where the fit calls for it, expand the inner ring with even, controlled heat rather than driving it on, and never heat a bearing with a flame or beyond the temperature given in the workshop manual for your engine
• Check the shaft and housing seats before fitting — scoring, burrs, corrosion or a worn seat will ruin a new bearing, and fretting marks mean the seat itself needs attention
• Fit the bearing square and fully home against its shoulder, note which way round any sealed, shielded or marked face must go, and lubricate with the grease or oil specified for the application before it is turned under load
