ASSEMBLY OF SPINDLE:
Only use a press that has the ram and bed 100% square to each other. If bearings
are not square in housing, bearings will wear out prematurely. Press on outer
race when inserting into hub and press on inner race when installing on spindle.
If bearings are being changed,
be sure to check bearing spacer
for wear. If wear is noticed,
insert new spacer. This is
critical because if spacer is
short by only .010”, the top
bearing will start to bind and
will result in premature failure.
Bearing with seal and shield
combination will be pressed
into the blade side of the hub
first with the seal side facing
out. Next; set spindle on press
bed
.
Install dirt shield and shim first
(see sketch above), set hub,
bearing end down, on to
spindle. You must use a tube
(Note: both ends must be
square) which will slide over
spindle and press on inner race
of bearing, until seated against shim.
Insert bearing spacer tube with hole end up. Set the remaining bearing, with
shield side up, open side on first, on to spindle. Press on inner race (this bearing
will be a loose fit in the hub so it will seat itself properly).
When all parts have been installed on the spindle, torque left hand nut to
(60) ft·lbs, and then tighten set screws in pulley. Once the assembly is complete,
fill the spindle with quality grease until it exits the top bearing. Rotate the housing
six revolutions by hand so the bearings will have the grease worked into them, and
at the same time, check for free movement. The assembly is now ready for
installation into the mower deck.
