Borg Warner Alternator Gasket & Seal Kit – A4867HA / 23801B
A direct-replacement gasket and seal kit for Borg Warner alternator service on compatible marine inboard engines. This kit provides the sealing components needed when removing, servicing, or reinstalling the alternator — restoring a proper seal at the alternator mounting area and preventing oil or moisture ingress after reassembly. Replace this kit any time the alternator is removed or when existing gaskets show cracking, compression set, or leaking.

Parts Desk Insights
The best time to replace this gasket and seal kit is while the alternator is already off the engine — the labour to remove and reinstall the alternator far exceeds the cost of the kit, so reusing old seals to save a few dollars is a false economy that often leads to a repeat job. The most common issue is customers ordering based on part number alone without confirming which alternator model is fitted to their engine; Borg Warner supplied alternators across a range of marine inboard applications, and the mounting and sealing configuration can vary. Always cross-reference A4867HA or 23801B against your engine’s parts diagram and confirm the alternator model number on the unit itself before ordering.
