plate to the trailer.
5b. locate the two 5/16" x 3" bolts and 5/16" flange
nuts located on the side of the chipper between the
trailer and the engine plate (Figure 5.3).
5c. Tighten both 5/16" bolts equally to move the
engine away from the chipper housing until the
belt deflection is 7/16" when a 20 lb. load is placed
against the belt (Figure 5.4).
5d. Tighten the four carriage bolts securing the engine
plate to the trailer.
5e. Tighten both 5/16" flange nuts to ensure the proper
