Introduction

You can use regular hand tools for removing fasteners, but using an impact driver will make the procedure easier.

What you need

Step 1

              Preparation

Before you begin, make sure the floor buffer is turned off and unplugged.
Brace the back of the floor buffer with your foot near the wheel axle and grasp the handle with both hands.
Slowly tilt the floor buffer back until the handle rests on your work surface.

Step 5

Remove the gear unit assembly and rotor from the floor buffer’s housing.
The gear unit assembly is fitted tightly into the housing. You will need to wiggle the assembly back and forth with a good amount of pressure to knock it loose.
The gear unit assembly and rotor are very heavy, so it may help to support the assembly from the bottom as you remove it.
Re-assembly tip: When installing the new gear unit assembly, make sure the screw holes line up with the housing’s screw holes.

gotta love it when the bearing stays stuck in the top of the floor maintainer housing and you have to work it out somehow.

AYANGA - Oct 29, 2020

in step five if you look where you removed phillips screw there are two threaded holes.if you use screws in those holes and tighten it acts like a gear puller
