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 (as per
diagram) set hub, bearing end
down, onto 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 remaining bearing with
shield side up, open side on first, onto 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 spindle, torque left hand nut to 60 ft-
lbs. and then tighten set screws in pulley. Once the assembly is complete, fill
with quality grease until it can be seen exiting 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.
