Product Overview: Genie Joystick Boot Kit (Part #139598 / 139598GT)

Genie Controller Joystick Boot 139598 139598GT for Genie Boom lift parts

The Genie Joystick Boot Replacement (Part #s 139598 and 139598GT) is a maintenance and repair kit designed to protect the sensitive joystick mechanisms on Genie boom lifts and telehandlers. This boot is a flexible, protective cover that seals the base of the joystick controller, preventing contaminants from entering and causing damage.

The "GT" suffix in 139598GT typically indicates a "Genie True" part, meaning it is a genuine OEM (Original Equipment Manufacturer) part guaranteed to meet Genie's specifications.

Key Features & Benefits

• Environmental Protection: The primary function of the boot is to create a seal against dirt, dust, grime, moisture, and weather elements. This is crucial for preventing premature wear and failure of the internal potentiometers or switches.

• Durability: Made from high-quality, flexible elastomer or rubber material designed to withstand extreme temperatures, UV exposure, oils, and repetitive motion without cracking or tearing.

• Improved Safety: A torn or missing boot can allow debris to jam the joystick, potentially leading to uncontrolled platform movement. Replacing it restores safe and predictable control operation.

• Cost-Effective Maintenance: This is a low-cost part that protects much more expensive components like the entire joystick controller or valve manifold. Regular inspection and replacement of worn boots is a key preventative maintenance practice.

• Easy Installation: The boot is designed for simple replacement without requiring special tools or major disassembly of the control box.

Function & Application

This part is applied in the following scenarios:

1. Preventative Maintenance: Routinely replacing boots during service intervals before they fail.

2. Repair: Addressing specific problems caused by a damaged boot, such as:

   • Erratic Joystick Behavior: The machine moves on its own or doesn't respond correctly to input.

   • Sticky or Hard-to-Move Joystick: Debris has entered the housing and impeded movement.

   • Visible Damage: The boot is cracked, torn, or completely missing.

Compatibility

• Machine Type: This part is used on Genie Boom Lifts (Z-Boom/Aerial Work Platforms) and Telehandlers.

• Specific Models: It is compatible with a wide range of Genie models. Always confirm compatibility using your serial number, but it commonly fits:

  • Genie Z-30/20N, Z-34/22, Z-45/25J

  • Genie S-40, S-40 Trax, S-45, S-60, S-65, S-80, S-85, S-105, S-125

  • Genie GTH-5519, GTH-1056 Telehandlers

  • ...and many other models with similar joystick designs.

• Controller Type: This boot fits over the individual joystick lever itself, not the entire control box. A single control box may require multiple boots (e.g., one for the drive joystick and one for the boom functions joystick).
