It provides all the critical sealing components needed to properly reseal the upper gear housing after service, inspection, or bearing replacement. Using the complete kit rather than replacing individual seals individually reduces the risk of a repeat repair caused by a seal or O-ring that was left in service.\u003c\/p\u003e\n\n\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eVolvo Penta SX-A\u003c\/li\u003e\n\u003cli\u003eVolvo Penta DPS-A\u003c\/li\u003e\n\u003cli\u003eVolvo Penta DPS-B\u003c\/li\u003e\n\u003cli\u003eVolvo Penta DPS-B1\u003c\/li\u003e\n\u003cli\u003eVolvo Penta FWD (selected configurations)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFitment is by drive family and serial number.

Inspect all sealing faces, bores, and adjacent hardware before assembly. Replace the full kit during any upper housing service rather than reusing individual seals that have been disturbed — the labor cost of reopening the upper unit to address a weeping O-ring far exceeds the cost of the kit. Tighten all fasteners to Volvo Penta service specifications for the upper gear housing assembly.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical FAQ\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does 3888917 replace 876392?\u003c\/strong\u003e\u003cbr\u003eA: Yes.

Upper gear housing bearings are separate items and should be confirmed from the drive-specific parts diagram.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Should I replace all seals in the kit even if some look fine?\u003c\/strong\u003e\u003cbr\u003eA: Yes. Once the upper housing has been disassembled, replacing the complete kit is best practice. Reusing seals that have been disturbed and compressed risks a fresh leak from a component that appeared serviceable during inspection.\u003c\/p\u003e\n\n\u003ch3\u003eAlternate Part Numbers\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eVolvo Penta 3888917\u003c\/li\u003e\n\u003cli\u003e876392 (superseded)\u003c\/li\u003e\n\u003cli\u003eOrbitrade 23021\u003c\/li\u003e\n\u003cli\u003eSierra 18-2726\u003c\/li\u003e\n\u003cli\u003eRecmar REC3888917 \/ REC23021\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\n\u003cp\u003eThis kit comes up most often when the upper gear housing is opened for a bearing replacement or when a gear-oil leak has been traced to the upper unit. The most common mistake is replacing only the obviously failed seal and leaving the remaining original O-rings in place. On a drive that has been in the water for years, the other seals are typically the same age and will fail shortly after — the full kit is worth it every time the housing is apart. The other common issue is ordering without confirming the drive serial number, since the upper housing configuration can differ between SX-A and DPS revisions.\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43564037767204,"sku":"3888917","price":212.0,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/49e60249-0531-4a19-b487-38ec8a84a9f5.png?v=1776399646","url":"https:\/\/marisolmarine.com\/products\/volvo-penta-upper-gear-housing-gasket-kit-3888917","provider":"Marisol Marine Company","version":"1.0","type":"link"}
