Step By Step Instructions

1
Before you replace a time shaft bearing retainer on your tiller make sure the engine has cooled and the on-off switch is in the “off” position.
2
We recommend performing this procedure with little or no fuel in the tank.

Now tip the tiller forward so it rests on the fuel tank and tine guard.
4
Note the orientation of the tines then remove the retaining pins and pull off both tine assemblies.
5
Next, use an adjustable wrench to rotate the tine drive shaft counter-clockwise to unthread it.
6
You can use a hammer to help fully remove the drive shaft along with the left side retainer, seal and bearing.
7
If you need to replace the retainer on the right side of the housing, use a phillips-head screwdriver to unthread the screws securing the cover then pull it off.
8
Lift out the worm gear.
9
Now insert the tine drive shaft in the reverse position and strike it with a hammer to knock out the retainer, seal and bearing.
10
Replace the bearing by fully seating it in the transmission housing.
11
The bearing should be recessed approximately a quarter-inch.
12
Replace the seal.
13
Install the new tine shaft bearing retainer by aligning it on the shaft then fully seat it in the housing.
14
Now reposition the worm gear and add some additional grease if necessary.
