Velvet Drive 71C / 72C Gasket & Oil Seal Kit A4867HA
Part Number: A4867HA (Velvet Drive / Borg-Warner)
The Velvet Drive A4867HA is a comprehensive oil seal, sealing-ring, O-ring, and gasket service kit for 71C and 72C marine transmissions. It supplies the primary sealing components needed for a complete transmission reseal or overhaul, including input and output oil seals, clutch sealing rings, O-rings, pump gasket, and a full service-gasket set. Components for both direct-drive and reduction-gear configurations are included in the kit.
Compatible Transmissions
- Velvet Drive 71C
- Velvet Drive 72C
- Borg-Warner / Velvet Drive 10-17 (direct and reduction)
- Borg-Warner / Velvet Drive 10-18 (direct and reduction)
The kit contains some components specific to reduction-unit configurations — not every seal or gasket will be used on every transmission. Confirm your exact model before disassembly.

Fitment Notice
Confirm the transmission identification plate before ordering. Match:
- 71C or 72C designation
- Transmission model number (10-17 or 10-18)
- Direct-drive or reduction-gear configuration
- Existing seal and gasket arrangement
Certain gaskets differ between the 10-17 and 10-18 models. Both sets are included in this kit, but using the wrong gasket during reassembly can cause sealing failures.

When This Kit Is Needed
- Transmission oil leaking from input or output shaft seals
- Leaks at housing joints or mating surfaces
- Transmission is being disassembled for overhaul or clutch service
- Pump or valve-body components are being removed
- Housing sections are being separated
- Existing seals have hardened from heat and age
- Full transmission reseal is being performed
Installation Notes
- Identify the exact 71C or 72C model and configuration from the identification plate before disassembly
- Keep components organized by transmission section throughout the overhaul
- Replace all disturbed paper gaskets — do not reuse them
- Lubricate new oil seals and O-rings with the specified transmission fluid during assembly
- Inspect input and output shaft surfaces where lip seals contact for wear or scoring
- Inspect clutch sealing-ring grooves for wear before installing new rings
- Use the model-specific 71-147 or 72-147 bearing-retainer gasket as appropriate for your model
- Use reduction-unit components (10-00-044-017 oil seal, L4-145/L4-147 gaskets) only on reduction-equipped transmissions
- Follow Velvet Drive torque, end-play, and clutch-clearance specifications during reassembly

Parts Desk Insights
The A4867HA is the right kit when the job calls for a full 71C or 72C reseal rather than a single shaft-seal replacement. It covers all the major oil seals, O-rings, clutch sealing rings, and gaskets needed across the 71/72 family, including model-specific pieces for 10-17, 10-18, and reduction configurations — everything typically disturbed during a complete overhaul.
The most common issue is customers confusing the 10-17 and 10-18 bearing-retainer gaskets during reassembly — both are in the kit, but they are not interchangeable. Pull the identification plate number before starting and set the correct gasket aside before closing up. Also note that the 10-00-044-017 reduction oil seal should only be installed on transmissions with a reduction-gear unit; installing it on a direct-drive model is a common mistake during bench assembly.
