It seals the inspection-cover opening in the crankcase, preventing oil seepage and contamination around the access-cover joint. The inspection cover provides access to the cylinder block interior for service and inspection — any time it is removed, this gasket should be replaced.\u003c\/p\u003e\n\n\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eVolvo Penta TAMD60A \/ TAMD60B \/ TAMD60C\u003c\/li\u003e\n\u003cli\u003eVolvo Penta TAMD61A \/ TAMD62A\u003c\/li\u003e\n\u003cli\u003eVolvo Penta TAMD63L-A \/ TAMD63P-A\u003c\/li\u003e\n\u003cli\u003eVolvo Penta TAMD70B \/ TAMD70C \/ TAMD70D \/ TAMD70E\u003c\/li\u003e\n\u003cli\u003eVolvo Penta TAMD71A \/ TAMD71B\u003c\/li\u003e\n\u003cli\u003eVolvo Penta TAMD72A \/ TAMD72P-A \/ TAMD72WJ-A\u003c\/li\u003e\n\u003cli\u003eVolvo Penta TAMD73P-A \/ TAMD73WJ-A\u003c\/li\u003e\n\u003cli\u003eVolvo Penta TAMD74A \/ TAMD74C \/ TAMD74L \/ TAMD74P\u003c\/li\u003e\n\u003cli\u003eVolvo Penta TAMD75P-A\u003c\/li\u003e\n\u003cli\u003eVolvo Penta TD610 \/ TD630 \/ TD640\u003c\/li\u003e\n\u003cli\u003eVolvo Penta TD70 \/ TD71 \/ TD730\u003c\/li\u003e\n\u003cli\u003eVolvo Penta TWD610 \/ TWD630 \/ TWD710 \/ TWD731 \/ TWD740\u003c\/li\u003e\n\u003cli\u003eRelated D5 \/ D6 \/ D7-family industrial applications using the same inspection-cover gasket architecture\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eConfirm the exact engine model and serial number using the Volvo Penta cylinder-block parts diagram before ordering.

If both inspection covers are being removed during the same service, order the full quantity shown in the parts diagram — many applications require two gaskets.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical FAQ\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does 20591544 replace 421121?\u003c\/strong\u003e\u003cbr\u003eA: Yes.

The key detail to get right is the quantity — if both inspection covers are coming off, order two gaskets before starting the job so you’re not waiting on a single gasket to finish the work. At this price point, ordering an extra gasket when you’re already in the area is cheap insurance against reopening the crankcase later.\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43563977670692,"sku":"20591544","price":17.7,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/images_adf98074-e82e-4f57-93a5-a066b5d91e8b.jpg?v=1788734144","url":"https:\/\/marisolmarine.com\/products\/volvo-penta-inspection-cover-gasket-20591544","provider":"Marisol Marine Company","version":"1.0","type":"link"}
