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 #8 (Refer to the parts manual when ordering parts.)
Cutter housing assemblies use sealed bearings and are maintenance free.
NOTE
WHEN PRESSING A BEARING IN OR OUT OF A CUTTER HOUSING APPLY CONSTANT PRESSURE TO THE RACE OR RACES THAT HAVE AN INTERFERENCE FIT. NEVER BEAT A BEARING IN OR OUT.
