Note: The weight of the Engine should be enough to tension the Belts properly but
depending on hardware looseness and cleanliness of Engine Mount pivot
area, you may need to push down slightly to aid in proper tension. The Belt
performs best with a slight amount of slack to allow for some slippage when
the Wedge encounters a tough log. Too much tension may stall the engine or
slip the belt on the engine pulley.
6. Install the new Belt and adjust tension as needed (Figure 33).
7. Tighten the two Engine Mount Bolts that are at the center of the machine
(shown) first and then tighten the outer two Bolts (Figure 32).
8. Reinstall the Guard (Figure 31).

Flanges together using two 9/16" Wrenches and remove the left side Guard

3. Remove the four short Flange Bolts and Locknuts that secure the right side
Guard to the Frame using a 9/16" Socket and Ratchet to remove the right
side Guard from the Splitter (Figure 35).
4. Disconnect the Return Springs from the Ram Bearing Hardware (Figure 36)
and pull the Ram out to the Wedge.
5. Center the Rack between the Frame.
