Volvo Penta Lower Gearcase Gasket Kit 3888822 | DPS-A DPS-B

Volvo Penta Lower Gearcase Gasket Kit Part No. 3888822

This is the OEM lower gearcase gasket and seal kit for selected Volvo Penta DPS sterndrive lower-unit service. Rather than sourcing each seal individually, 3888822 packages the principal gaskets, O-rings, and sealing rings required for the lower gear-housing service operation. It is identified as the Repair Kit, Lower (Key 3) in documented DPS repair-kit diagrams.

Drive & Serial Number Fitment Notice

Match this kit by the exact drive model and serial number not by engine model alone. Volvo Penta uses several related lower-unit gasket kits in the same repair-kit family (including 3888821 and 22612828) with different seal combinations. The correct kit depends on the specific drive configuration and repair-kit diagram position.

When to Use This Kit

Use a fresh gasket and seal kit whenever:

• Opening the lower gear housing for any service operation
• Rebuilding the lower unit
• Replacing internal bearings or shafts that require disturbing the seals
• Correcting gear-oil leakage or water intrusion into the drive oil
• Existing O-rings or sealing rings are flattened, hardened, cut, or damaged during disassembly

Seals disturbed during disassembly should be replaced rather than reused.

Installation Notes

Before assembly, clean all gasket and O-ring grooves and inspect mating surfaces for corrosion or damage. Lubricate seals only as specified in the Volvo Penta service procedure, confirm sealing-ring orientation, and replace any damaged drain-plug or housing seals at the same time. Pressure- and vacuum-test the gearcase after assembly before returning the drive to service. Use the Volvo Penta workshop procedure for correct torque values and seal installation depth.

Parts Desk Insights

Best use: Order 3888822 when your DPS-A or DPS-B lower-unit repair-kit diagram confirms this as the correct lower kit (Key 3) for the service being performed. Using a complete kit ensures all sealing components are renewed in one step, reducing the risk of a secondary leak from a missed or reused seal.

Common customer issue: Because Volvo Penta lists several visually similar lower-gearcase kits (3888821, 3888822, 22612828) in the same repair-kit family, ordering by part description rather than the diagram position and drive serial number is the most common mis-order. Always match the kit to the exact repair-kit diagram key and drive serial number before purchasing.
