1556907 Gasket | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta gasket is a formed OEM sealing component used in the engine gasketed joint. It is manufactured to the original Volvo Penta dimensions and interface requirements so the mating joint retains its intended fluid, gas or contamination barrier. Maintains the revised OEM service configuration. In service, it seals the specified mating faces and maintains separation between fluid or gas passages. Fitment is controlled by the exact engine or product configuration and serialised parts list; confirm OEM number 1556907 against the installed assembly before ordering.

🔌 Function

The gasket forms a compressible seal between two mating engine surfaces, preventing the escape of fluids, gases or pressure at the joint. It compensates for minor surface irregularities to keep the connection tight throughout normal engine operation.

⚠️ Common Signs of Failure

• Visible fluid seepage, weeping or staining around the sealed joint
• Loss of pressure or a drop in system performance traceable to the joint
• Hardened, brittle, cracked or flattened gasket material on inspection
• Repeated need to retighten fasteners at the joint to stop leaks
• Corrosion or deposit build-up on the mating faces around the gasket

🛠️ Service Notes

• Fit a new gasket every time the joint is disturbed — a gasket takes a permanent set once it has been torqued and will not seal reliably a second time
• Scrape both faces back to clean bare metal, keeping the blade at a shallow angle so it lifts the old material without gouging the surface, and use a plastic scraper on aluminium castings
• Check the faces for flatness, cracks and corrosion pitting, and make sure no old gasket, carbon or hardened sealant is left in the corners or around the bolt holes
• Fit the gasket dry unless the workshop manual for your engine calls for a sealant, and then only the type it specifies — surplus sealant squeezes out into oil, coolant and fuel passages
• Draw the fasteners down progressively in the sequence and to the torque given in the manual for your engine, and recheck after the first heat cycle where the manual asks for it
