SPINDLE REASSEMBLY
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 will be pressed into the
blade side of the hub first, orientation
does not matter. 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 on to spindle,
orientation does not matter. 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. The assembly is now ready for installation
into the mower deck.
