  8. CAUTION: Wheel assemblies are heavy, awkward to handle, and difficult to control due to extreme offset of tire and rim. Two people are required for wheel removal.

    When removing outer wheel, keep holding inner wheel, avoiding unexpected movements.

    IMPORTANT: For S660 and S670 machines the four wheels on the front axle are the same, but for S660 rice machines the four wheels are not the same.

    While supporting outer wheel assembly, remove wheel bolts, washers, spacers, and front wheels. Move wheel assemblies away from machine.

    NOTE: Machine can be transported with inner wheels left in-place. Likewise, outer wheels can be serviced off machine while leaving inner wheels undisturbed.

    Follow same steps to remove inner wheels:

  • Loosen wheel bolts one full turn.
  • Support wheel assembly.
  • Remove wheel bolts, washers, spacer ring, and inner wheel.
