21412916 Cover | Genuine Volvo Penta Part

🔧 Product Description

Service cover used over the oil-filter / strainer adapter in Volvo Penta IPS-A through IPS-E drives. It closes the lubrication-system service opening, compresses the specified O-ring and protects the filter and sensor area from external contamination.

⚙️ Key Features

• Genuine Volvo Penta IPS oil-filter cover
• Used with adapter 21412912
• Compatible with IPS-A through IPS-E lubrication assemblies
• Seals with the specified O-ring and three socket screws
• Machined cover for correct oil-system pressure retention
• Engine type: Volvo Penta IPS marine propulsion drive

🔌 Function

Closes and seals the oil-filter adapter opening so the IPS lubrication circuit can retain oil pressure and remain protected from contamination.

⚠️ Common Signs of Failure

• Oil seepage around the cover
• Distorted or corroded sealing surface
• Stripped mounting threads
• Cracked cover from overtightening or impact
• Repeated leakage caused by a damaged O-ring groove

🛠️ Service Notes

• Clean both sealing faces back to clean metal and check the cover for distortion, cracks or pulled bolt holes before refitting — a warped flange will not seal even with a new gasket
• Where the joint uses a gasket, seal or O-ring, always fit a new one and seat it dry unless the workshop manual for your engine specifies a sealant; never try to make a poor joint tight with extra sealant
• Tighten the fasteners progressively and evenly, working out from the centre, to the figure given in the manual for your engine — pressed steel, alloy and plastic covers distort easily if pulled down hard or unevenly
• If the cover carries a shaft seal or bearing, support it square to the shaft as it goes on so the seal lip is not nicked or rolled over
• Check that any breather, drain or oil return passage in the cover is clear before final tightening, and look for leaks once the engine has been run up to temperature
