Replacing the Mow-Ball

or Line Plates

Tools and Supplies Needed:



Phillips head Screwdriver with at least a 6" shank



Gloves

2. Align the hole in the Anti Wrap Canister with the hole in the internal housing

at the location shown (Figure 30).

3. Insert a Philips Head Screwdriver into the hole in the Anti Wrap Canister and

the hole in the internal Housing.

4. Rotate the Mow-Ball

Assembly until the Screw Driver slides into a hole in

the shaft, locking it into place.

5. Looking down at the top of the Frame, turn the Mow-Ball

counter clockwise

until it unscrews completely from the Bearing Housing.

Note: If the Mow-Ball

continues to turn, but does not come off, check to be sure

that you locked the Screwdriver into the shaft.

If the Mow-Ball will not turn by hand a 9/16" Socket can be used on the Bolt

(inside the bottom of the Mow-Ball) to loosen it. You may need to clean grass
or debris out of the recess first.

6. Slide the Line Plates off the Shaft.

7. Place the Spacer and Anti Wrap Canister (with the lip facing up) onto the

Shaft (Figure 31).

8. Align the flats at the center of the Plates with the flat on the shaft and slide

the Line Plates onto the Shaft. Ensure they are facing top side up as shown.

9. Place the head of the Mow-Ball

Bolt so it is sitting in the hex cavity at the

bottom of the Mow-Ball

10. Looking down at the top of the Frame, hold the Bolt Head in place with your

finger and turn the Mow-Ball

counterclockwise to start the Bolt into the

Shaft. The Bolt has a left hand thread.

11. Tighten the assembly securely by turning the Mow-Ball

clockwise when

looking down on the top of the Frame.

12. Remove the Screwdriver.

Note: When finished there should be no gaps between any of the components.

Improper installation can cause damage to the trimmer bearings. Follow
these directions carefully to protect your machine from damage. Reassemble
the components in the order shown in figure 31.

Always make sure you remove the screwdriver from the head assembly when finished. Failure to remove the screwdriver could
cause injury when the head assembly is engaged.
