🔧 Product Description

This genuine Volvo Penta spindle is a precision pivot and locating spindle used in the cooling-water filter bracket spindle. 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 provides the pivot or locating spindle for the cooling-water filter bracket/selector arrangement. Selection must be confirmed by OEM part number 1661686, the exact engine/product model, serial number and the installed assembly configuration.

⚙️ Key Features

• OEM Volvo Penta part number 1661686
• System group: Cooling System
• Net weight: 0.073 kg (approx. 72.6 g)
• Fits D9, D11 and D12 marine diesel engines plus TAD, TAMD, TWD, THD, TID and DH10A series engines
• Supplied as an individual component for cooling system service

🔌 Function

The spindle acts as the pivot shaft for a moving element within the engine's cooling circuit, allowing controlled movement while holding correct alignment. Keeping it in good condition ensures the associated cooling component operates freely and coolant flow is regulated as designed.

⚠️ Common Signs of Failure

• Corrosion, pitting or scale build-up from long-term coolant exposure
• Seizing or stiff movement of the component it supports
• Wear or scoring on the bearing surface causing excessive play
• Coolant weeping or seepage around the spindle location
• Erratic or unstable engine coolant temperature readings

🛠️ Service Notes

• This spindle operates the cooling-water filter bracket/selector, not a pump or drive shaft like most other spindles catalogued under this type — check the selector still turns smoothly through its full range before returning it to service
• At approximately 73 g this is a small component — handle it with the bracket on removal, since a bent spindle will bind the selector
