1675920 Shaft | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta shaft is a machined coolant-pump drive shaft used in the engine coolant-pump shaft. 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 transmits drive through the coolant pump and supports the impeller at the specified bearing and seal locations. Selection must be confirmed by OEM part number 1675920, the exact engine/product model, serial number and the installed assembly configuration.

🔌 Function

The shaft carries the water pump impeller and transfers drive rotation to it so coolant is circulated through the engine block, heat exchanger and cooling circuit. Its bearing surfaces and seal journal keep the impeller running true and prevent coolant escaping into the drive end.

⚠️ Common Signs of Failure

• Coolant weeping or dripping from the pump weep hole, indicating seal wear at the shaft journal
• Engine overheating or slow warm-up recovery caused by reduced coolant flow
• Rumbling, grinding or whining noise from the pump area as bearing surfaces wear
• Visible shaft play, wobble or belt misalignment at the pump pulley
• Scoring, pitting or corrosion on the shaft journal found during pump overhaul

🛠️ Service Notes

• Handle and store the shaft so the bearing journals and seal running surfaces stay unmarked — a nick on a seal track will cause a leak that no new seal will cure
• Remove the protective coating and check the shaft for straightness, scoring, pitting and stepped wear at the journals, splines and seal areas before fitting
• Lubricate journals, splines and seal surfaces with clean oil of the grade specified for the assembly as it goes together, and renew the seals and any single-use nuts or locking devices disturbed on removal
• Draw bearings and couplings on square with a press or drawing tool that loads only the correct race — hammering a bearing onto a shaft marks the races and can distort the shaft
• Set end float, backlash and shim thickness to the values in the workshop manual for your unit, then turn the assembly by hand to confirm it is free before applying power
