Transmission Plug and O-Ring Assembly for Spartan HTE/HTJ Hydrostatic Lawn Mower Service SKU: 450-0034-00

Hydrostatic transmission fluid leaks start small but quickly become expensive problems. When service plugs wear out or O-rings harden and crack, hydraulic fluid escapes, leaving your mower's hydro system vulnerable to contamination and pressure loss. This genuine Spartan replacement assembly restores the proper seal your HTE and HTJ transmissions need to maintain hydraulic integrity.

Why This Assembly Matters

• Genuine Spartan design ensures exact fit for HTE and HTJ hydrostatic transmissions
• Quality materials resist hydraulic fluid exposure and repeated service cycles
• Prevents costly fluid loss and contamination that damages hydraulic components
• Complete plug and O-ring combination eliminates guesswork during service

Not compatible with Hydro-Gear or Tuff Torq models - this assembly is specifically engineered for Spartan's HTE and HTJ hydrostatic transmission systems. Clean the port thoroughly before installation and apply transmission fluid to the O-ring for proper sealing. With S&H Parts' 55 years of experience, we'll help you get the right part for your specific mower.
