CUTTER HOUSING SPINDLE
ASSEMBLIES
The cutter housing assembly is designed with a
slip fit inner race and pulley. The sole purpose
of the setscrew in the pulley is to hold the
housing assembly together. The setscrew is
not meant to secure the pulley. The pulley is
secured by pinching the pulley to the inner race
of the bearings using the blade bolt and nut.
Tighten the setscrews after you have pinched
the assembly together with the blade bolt and
nut.
Each cutter spindle on 48" Models have a different
stack up of spacers and pulleys, to achieve proper
belt alignment. The left cutter spindle on 48" Models
is the same as 36" Models. See figure 7 (Refer to
the parts manual when ordering parts.)
Cutter housing assemblies use sealed bearings
and are maintenance free.
WHEN PRESSING A BEARING IN OR OUT OF A
CUTTER HOUSING APPLY CONSTANT PRESSURE
TO THE RACE OR RACES THAT HAVE AN
NEVER BEAT A BEARING IN OR OUT.
