1546480 Sealing Ring | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta sealing ring is an engine-lubrication sealing component used in the front timing-cover crankshaft sealing. It is manufactured to the original Volvo Penta dimensions and interface requirements so engine oil is retained at the specified joint or rotating surface. Front crankshaft/timing-cover oil seal; approximately 43.68 mm ID × 62.23 mm OD × 8.12 mm wide. In service, it seals the crankshaft where it passes through the front timing cover to retain engine oil and exclude contamination. Fitment is controlled by the exact engine or product configuration and serialised parts list; confirm OEM number 1546480 against the installed assembly before ordering.

🔌 Function

Seals the crankshaft where it passes through the front timing cover to retain engine oil and exclude contamination. Inspect the shaft and housing for grooves, scoring or run-out, install the seal squarely at the specified depth and verify the joint after the engine reaches operating temperature.

⚠️ Common Signs of Failure

• Visible weeping, seepage or drips around the sealed joint
• Loss of system pressure or unexplained fluid level drop
• Hardened, cracked, flattened or distorted ring on inspection
• Staining or residue tracking below the connection point
• Repeated need to retighten the fitting to stop a leak

🛠️ Service Notes

• Always fit a new sealing ring rather than reusing the old one — a ring that has been compressed once has taken a set and will not seal reliably a second time
• Clean the groove or seat and check it for scoring, corrosion and old sealant before fitting; a mark across the sealing face will leak however good the ring is
• Ease the ring into place without stretching, twisting or dragging it over sharp edges or threads, and check it is seated squarely all the way round before closing the joint
• Do not add sealant or jointing compound unless the workshop manual for your engine calls for it, and tighten the joint or union to the figure given in that manual
• Check the joint for weeping once the engine has been run up to temperature and allowed to cool, as many sealing rings only show a leak after a heat cycle
