DEALER SERVICE
The information in this section is written for dealer
service personnel. The repair described here requires
special skills and tools. If your shop is not properly
equipped or your mechanics are not properly trained
in this type of repair, you may be time and money
ahead to replace complete assemblies
Always wear relatively tight and belted cloth-
ing to avoid entanglement in moving parts. Wear

equipment for eyes, hair, hands, hearing, and
head.

tem failures, or mechanical component failures.

Spindle Repair Tips
• As a reference point, the top of the spindle hous-
ing is the short portion.
• To minimize wear, bearing cups, cones and
sleeves are press-fit to the shaft and will require a
press or similar device for removal.
• When disassembling, support the housing casting
to prevent damage.
• Remove bearing cups by placing a punch in the
housing slots and driving cup out. Alternate punch
positions from side to side. Use care to prevent hous-
ing damage.
