To Reassemble the Mow-Ball
™
Support Assembly
WARNING: Before performing any maintenance procedures, the engine should be stopped
and the spark plug wire disconnected.
Caution: An improper installation may cause
damage to the bearings. Please follow these
directions carefully.
Tool Needed:
• Phillips head screwdriver
Note: If you removed and are reinstalling the
Wagner Anti-Wrap Device, be sure the
bracket is flush with or slightly above the
bottom edge of the bearing housing shaft—
not below it.
1. Reassemble the components in the order
shown in Figure 29.
• Be sure bearing shield washer is beveled
side up.
• Be sure to align the notches in the cutting
height disks and the Mow-Ball
™
Support
before completing assembly.
• Check the head of the Mow-Ball
™
Support bolt. It should sit in the groove
(square washer) at the bottom of the Mow-
Ball
™
Support.
2. Hold the Mow-Ball
™
bolt head in place
with one finger and turn the Mow-Ball
™
Support assembly clockwise until it's
finger tight. Holding the bolt in place
prevents it from turning in the groove and
digging into the Mow-Ball
™
Support.
3. Spin the Mow-Ball
™
Support to be sure
the anti-wrap device does not hit the
trimmer head plate. There should be about
1/16" to 1/8" of clearance. There will be some resistance as you turn the trimmer head because
of the belt and pulley.
4. IMPORTANT! Return the orange vinyl plug to the bearing housing. This will keep out
dirt and debris and ensure the long life of the bearings. Do not put oil or grease in the hole.
