A. Position the engine base to obtain from 5.34 to
5.46 inches (13.6 to 13.9 cm) between the engine
output shaft and power shaft center lines (Fig. 65).
B. Align machined face of input power and shaft in-
put pulleys to within a maximum of 0.03 inch (0.76
mm) misalignment (Fig. 65).
C. Secure engine base to the front of the frame with
two cap screws and lock washers (Fig. 51).
D. Secure engine base to the back of the frame with
two cap screws and lock washers (Fig. 50).
E. Reinstall idler pulley to the bellcrank assembly
(Fig. 51).
IMPORTANT: Over tightening belts will overload the
bearings and increase wear on the belt.
12. Adjust tensions of differential and both drum drive
belts from 20 to 25 lbs (89 to 111 N) of force. Use a scale
to pull on the idler pulley while securing the idler brack-
ets by tightening both carriage bolts and lock nuts (Fig.
66).

the three cap screws and lock washers (Fig. 50)

socket to tighten the four cap screws and lock washers
to each cover (Fig. 49).
