coolant stops, install drain plug.
7.
Slowly fill radiator with a 50/50 mixture of water
and permanent ethylene glycol anti-freeze. Install

Adjusting Belts (Fig. 45–46)
Check condition and tension of all belts after first day
of operation and every 200 operating hours thereafter.
Raise bed (if so equipped) and place safety support on
extended lift cylinder to hold up bed.
Alternator Belt (Fig. 45)
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. 46)
1.
Check tension by depressing belt at mid span of
fan and drive shaft pulleys with 10 Kg (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.
2.
To adjust belt tension, loosen idler pulley
mounting nut, move pulley to increase tension
and tighten nut.
