It's standard practice to replace the lip seal any time the intermediate housing is opened, regardless of visible wear, since reinstalling an old seal into a freshly serviced housing is a common source of repeat failures.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCommon Issues:\u003c\/strong\u003e The most frequent ordering mistake with this part is confusing it with other seals in the IPS assembly — there are several sealing components in close proximity, and they are not interchangeable. Matching by IPS generation and exploded-diagram position is the most reliable method. If you're unsure which seal you need, send us your IPS drive model and the diagram position reference and we'll confirm before you order.\u003c\/p\u003e\n\n\u003ch3\u003eWhen to Replace\u003c\/h3\u003e\n\u003cp\u003eReplace this lip seal when there is evidence of water intrusion into the intermediate housing, visible deterioration or damage to the sealing lip, or any time the intermediate housing is disassembled for bearing or drive component service. Inspect the mating sealing surface and nearby O-rings at the same time and replace as needed.\u003c\/p\u003e\n\n\u003ch3\u003eService Interval\u003c\/h3\u003e\n\u003cp\u003eThis seal is not a scheduled replacement item under normal operating conditions. However, it should be inspected and replaced whenever the IPS intermediate housing is disassembled. Volvo Penta recommends IPS drive service at regular intervals — refer to your drive's service manual for the applicable schedule.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical FAQ\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How do I confirm this is the correct seal for my IPS drive?\u003c\/strong\u003e\u003cbr\u003eA: Cross-reference your IPS drive generation (IPS-A through IPS-F or IPS10-A) against the Volvo Penta parts diagram for the intermediate housing assembly. The diagram position number is the most reliable confirmation. Contact us with your drive model if you need help identifying the correct part.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: My old part number is 21452859 — is 21535352 a direct replacement?\u003c\/strong\u003e\u003cbr\u003eA: Yes. 21535352 is the current OEM part number that supersedes 21452859. It is the correct replacement for that earlier reference.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Should I replace other seals and O-rings at the same time?\u003c\/strong\u003e\u003cbr\u003eA: Yes — whenever the intermediate housing is open, it's best practice to replace all seals and O-rings in the assembly. This avoids having to re-open the drive shortly after for a seal that was borderline at the time of service.\u003c\/p\u003e\n\n\u003ch3\u003eRelated Parts\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/volvo-penta-ips10-a-propulsion-oil-filter-23935461\"\u003eVolvo Penta IPS10-A Propulsion Oil Filter 23935461\u003c\/a\u003e — service alongside during IPS maintenance\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/volvo-penta-ips-shift-control-solenoid-valve-11418522\"\u003eVolvo Penta IPS Shift Control Solenoid Valve 11418522\u003c\/a\u003e — related IPS drive component\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/volvo-penta-dpi-service-kit-23538670\"\u003eVolvo Penta DPI Service Kit 23538670\u003c\/a\u003e — comprehensive IPS\/DPI drive service kit\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/volvo-penta-sealing-ring-1546221\"\u003eVolvo Penta Sealing Ring 1546221\u003c\/a\u003e — related sealing component\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/volvo-penta-gasket-kit-3812357\"\u003eVolvo Penta Gasket Kit 3812357\u003c\/a\u003e — gasket kit for drive service\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43563988254756,"sku":"21535352","price":529.0,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/c3e9832e-ebe1-4562-81c2-f35e66e05dae.png?v=1787352133","url":"https:\/\/marisolmarine.com\/products\/volvo-penta-lip-seal-21535352","provider":"Marisol Marine Company","version":"1.0","type":"link"}
