This guide shows how to replace the rotor inside a Clarke Floor Buffer 01278A 2016.
You can use regular hand tools for removing fasteners, but using an impact driver will make the procedure easier.

-
-
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.
-
-
-
Use a 3/16" hex key or driver bit to remove the four 18.6 mm-long screws securing the shield brush to the bottom of the floor buffer.
-
-
-
Pull the shield brush straight off the bottom of the floor buffer.
-
-
-
-
Remove the eight 23.1 mm-long Phillips #3 screws securing the gear unit assembly and rotor to the floor buffer's housing.
-
-
-
Remove the gear unit assembly and rotor from the floor buffer's housing.
use 1/4-20 bolts at the 3 and 8 o'clock position to pull the gear unit off. Alternate tightening the bolts and unit will come right off.
-
-
-
Rest the center threaded bolt of a gear puller on the center of the rotor's driveshaft.
-
Attach the legs of the gear puller to the outer bottom edges of the bearing, and tighten the bolt by hand until the gear puller is snug on the bearing.
-
-
-
Use a wrench to tighten the gear puller until the bearing comes loose.
-
Remove the bearing.
-
-
-
Use two pry bars and place the ends between the rotor and gear unit assembly as far toward the center as possible.
-
Apply force to both pry bars in opposite directions to disconnect the rotor from the gear unit assembly.
-
Remove the rotor from the gear unit assembly.
-
To reassemble your device, follow these instructions in reverse order.

gotta love it when the bearing stays stuck in the top of the floor maintainer housing and you have to work it out somehow.
there’s an excessive grinding noise, does anyone what could be it and what might be a remedy? thanks in advance
Did you figure it out mine is doing the same
James -
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
Very good illustrations.
What could my problem be when my maintainer runs slowly? and then trips the 20amp breaker.
having the same problem as Terry , any advice would be helpful.
Verify the integrity of the power supply circuit and switches, check for shorts. Check or replace the capacitor. If that does not and it probably won't. remove the rotor. Look for arc damage. If there is evident indicators of electro arc damage to the rotor you will need a new motor assembly, which includes the rotor. I also advise replacing the relay assembly if the motor requires replacement as it has likely drawn far above it's intended amperage and due to the resulting heat it may have suffered damage that could compromise future performance, even if it appears to be in good condition at the moment.
MARK -
I just did this replacement plus replaced the coil above the rotor, and now my machine is tripping breakers after running for a few seconds, does anyone know why this could be?
James, Sounds like you have bad bearings. They are not hard to change. Just take it easy the first time you do any and you should makeit through fine.
