1660609 Ball Bearing | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta ball bearing is a precision rolling-element support component used in the engine overhaul 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. In service, it supports the designated rotating shaft during engine operation and controls radial movement at the overhaul position. Selection must be confirmed by OEM part number 1660609, the exact engine/product model, serial number and the installed assembly configuration.

🚤 Compatibility

• Engine Family: D, TD, AQD, TMD, MD, TAMD, AD, AQAD, TWD, TID, THAMD, HS, TAD, KAD, KAMD

🔌 Function

The ball bearing supports a rotating shaft, carrying radial and light axial loads while allowing it to turn with minimal friction. Correct bearing condition maintains shaft alignment and prevents play in the assembly it supports.

⚠️ Common Signs of Failure

• Rumbling, growling or grinding noise that changes with engine or shaft speed
• Excessive radial or axial play felt when the shaft is moved by hand
• Rough or notchy rotation instead of smooth free spinning
• Localised overheating or discoloured grease around the bearing housing
• Visible pitting, brinelling or spalling on the races and balls, or a damaged cage or seal

🛠️ 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
