extended lift cylinder to hold up bed.
Alternator Belt (Fig. 47)
1.
Check tension by depressing belt at mid span of
crankshaft and alternator pulleys with 30 Nm (22
lbs.) of force. A new belt should deflect 7–12 mm
(0.3–0.5 in). A used belt should deflect 10–14mm
(0.4–0.55 in.). If deflection is incorrect, proceed
to next step. If correct, continue operation.
2.
To adjust belt tension:
Loosen alternator mounting bolts. Using a bar,
rotate alternator until proper belt tension is
attained, then tighten mounting bolts.

Fan Belt (Fig. 48)
1.
Check tension by depressing belt at mid span of
fan and drive shaft pulleys with 30 Nm (22 lbs.)
of force. A new belt should deflect 12–14mm
(0.48–0.58 in.). A used belt should deflect
14–16mm (0.55–0.65 in.). If deflection is
incorrect, proceed to next step. If correct,
continue operation.

(Fig. 49)
1.
Position vehicle on level surface, stop engine and
engage the parking brake.
2.
Adjust ball joint on accelerator cable to allow
2.5–6.3mm (0.100"–0.250") clearance between
accelerator pedal and top of diamond tread floor
plate, when a 11kg (25 lb. force) is applied to
center of pedal. Tighten locknut.
