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.
For greaseable spindles ; 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.
For maintenance free spindles ; rotate the housing six revolutions by hand to check for
free movement. The assembly is now ready for installation into the mower deck.
The procedure is now complete.
*- For maintenance-free spindle bearings, both top & bottom bearings are the same.
Shield / seal orientation is the same on both sides of these bearings.
