Overview

The Bigfoot M26855 retrofit kit equips your Bigfoot hydraulic tongue jack with a hex key manual override. If you lose 12-volt power, blow a fuse, or experience a controller fault, this upgrade lets you safely actuate the jack using a standard hex/Allen tool—no disassembly or risky “cracking lines” required.

Key Benefits

• Fail-Safe Operation: Raise or lower the jack without 12V power.
• Tool-Driven Control: Hex interface provides positive, non-slip engagement.
• Clean Retrofit: Designed as a service upgrade for Bigfoot hydraulic tongue jack assemblies.
• Field-Friendly: No need to open hydraulic lines or bleed the system for routine use.

What’s Included

• Manual override drive assembly with hex interface (M26855)
• Mounting hardware (as supplied)
• Basic installation/operation sheet

Installation (Summary)

1. Park on level ground, chock wheels, support tongue as needed.
2. Disconnect 12V power at the battery or switch.
3. Access the jack head; remove fasteners per the instruction sheet.
4. Install the M26855 override assembly; torque hardware to spec.
5. Restore power, test powered and manual operation end-to-end.
