1660115 Ball Bearing | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta ball bearing is a precision rolling-element support component used in the fan-console and fan-bearing assembly. 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. In service, it supports the fan shaft in the fan-console assembly and permits low-friction rotation under belt and fan load. Selection must be confirmed by OEM part number 1660115, the exact engine/product model, serial number and the installed assembly configuration.

🚤 Compatibility

• Engine Family: TWD, TID, TAMD, D, TD, TAD, MD

🔌 Function

The ball bearing locates and supports a rotating shaft in the engine cooling circuit, allowing it to turn freely while carrying radial and axial loads. Correct bearing condition keeps the shaft running true so coolant flow and drive alignment are maintained.

⚠️ Common Signs of Failure

• Growling, rumbling or whining noise that changes with engine speed
• Detectable radial or axial play, or wobble, in the supported shaft
• Rough, gritty or binding rotation when turned by hand
• Coolant seepage or seal weeping caused by shaft movement from a worn bearing
• Discoloured, rusted or heat-marked bearing races indicating loss of lubrication

🛠️ 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
