Maintenance: Check Top Bearing
This task should only be done by a qualified
service technician
The bearing in the breaker should be checked at
least two times per year.
Check the bearing by:
1. Removing the bail clamp and ice chute cover
2. Unscrewing the ice sweep
3. Removing the water shed & unscrewing the
breaker cover (left hand threads).
Inspect the top of the bearing. When new the
grease is white, over time some gray will appear
over the rollers, that is normal. Add grease to
replace the gray grease or if gaps between rollers
are visible. If grease is watery, all gray or rust is
visible, have the bearing replaced. See the next
page for more information.
Note: When checking the top bearing, always
inspect the drip pan for water seal leaks. If water is
present in the drip pan, service the water seal and
check the gear reducer's lubricant. See the next
page.
