Bzcovac Transaxle Seal Service Kit for Hydro-Gear ZT-2800 ZT-3100 ZT-3200 ZT-3400 — 30-Piece Rebuild Seal & Hardware Set

The Bzcovac 72994 Transaxle Seal Service Kit is a 30-piece replacement set designed to rebuild and reseal Hydro-Gear ZT-2800, ZT-3100, ZT-3200, and ZT-3400 transaxles, restoring hydraulic sealing and preventing leaks.

If you maintain commercial mowers, garden tractors, or any equipment using Hydro-Gear ZT series transaxles, clean seals and correct fittings matter. This kit collects the common sealing parts—gaskets, dust seals, seal lips, plugs, bolts, washers, rings, and pins—so you can perform a thorough transaxle or charge pump gerotor service without sourcing each component separately. Components are built from durable materials intended to resist wear, heat, and contaminants encountered in hydraulic systems.

What components are included and why do they matter?

The kit contains 30 pieces that address every typical sealing point during a rebuild. Replacing worn seals and hardware helps maintain hydraulic pressure, keeps fluid in the pump, and keeps dirt out of sensitive areas.

• Seal lips and dust seals to stop fluid leakage and block contaminants
• Gaskets to restore mating-surface sealing and prevent external leaks
• Seal plugs and rings for internal ports and clearances
• Bolts, washers, and pins to replace corroded or stretched fasteners

Which Hydro-Gear transaxle models does this kit fit?

This service kit is engineered for broad compatibility across ZT-series Hydro-Gear transaxles. It covers many ZH, ZJ, ZK, ZL, and ZM variants used in ZT-2800, ZT-3100, ZT-3200, and ZT-3400 units, making it suitable for full rebuilds and partial repairs.

• Works with Hydro-Gear ZT-2800 transaxles (ZH, ZJ, ZK, ZL, ZM)
• Compatible with ZT-3100, ZT-3200, and ZT-3400 (common ZJ/ZL/ZM variants)
• Ideal for both charge pump gerotor and general transaxle sealing points

How do the materials and design improve performance and longevity?

Parts in the 72994 kit are manufactured from high-strength, tear-resistant materials selected for sealing under thermal and mechanical stress. Proper material selection helps maintain pressure, resist abrasion, and tolerate typical operating temperatures, limiting premature failure.

• Tear-resistant seal compounds to withstand shaft movement and pressure
• Temperature-compatible gaskets that maintain shape and compression
• Corrosion-resistant hardware for long-term mechanical integrity

Can I do the rebuild myself and what else should I prepare?

Experienced DIY mechanics and professional technicians can use this kit for routine transaxle overhaul work. For best results, pair the kit with new fluid, clean housings, and the correct torque specs from the service manual.

• Inspect housings and shafts for wear before installing new seals
• Replace fluid and clean all mating surfaces to prevent contamination
• Use proper tools and follow Hydro-Gear torque and assembly procedures

Who is this for: The Bzcovac 72994 Transaxle Seal Service Kit is aimed at landscapers, groundskeeping shops, fleet maintenance technicians, and experienced DIYers who service Hydro-Gear ZT series transaxles. If you perform regular maintenance, do partial repairs, or rebuild charge pump gerotors, this complete 30-piece kit saves time by supplying the essential seals and hardware needed to restore reliable hydraulic sealing and reduce downtime.
