website: http://www.progressiveturfequip.com/service
Spindle repair requires special skills and tools, a shop press is
required. If your shop is not properly equipped or your
mechanics are not properly trained in this type of repair,
complete spindle assemblies are available as service parts.

washer (8) & shim (4) from spindle assembly. The spindle nut
is left-hand thread.
Make sure that the press ram and bed 100% square to each
other. If bearings are not square in housing, bearings will wear
out prematurely.
2) Place assembly in shop press with support under spindle
housing flange and press spindle down through housing.
3) Remove bottom bearing from spindle and top bearing from
housing
IMPORTANT! Removing bearings from spindle / housing
causes permanent damage to the bearings. New bearing
must be used in re-assembling the spindle.
4) Inspect bearing spacer faces for wear. If any wear is present,
replace spacer with new.
IMPORTANT! Failure to replace a worn or damaged spacer
will lead to premature top bearing wear.
5) Place housing in press (upside down).

is not detrimental to the operation of the spindle.

(15), pulley (1) and set screw (14) on to spindle.
