4. MAINTENANCE
2. Using two open-end wrenches, loosen fuel line
connection at injection nozzle.
3. Crank engine over with starting motor, (but do
not start engine), until fuel free from air bubbles
flows out of loosened connection. Retighten
connection to 27 Nm (20 lb-ft.).
4. Repeat procedure for remaining injection nozzles
(if necessary) until all air has been removed from
fuel system.
If engine still will not start, see your authorized
servicing dealer or engine distributor.
4.11 FAN/ALTERNATOR BELT
Low belt tension causes slippage resulting in excessive
cover wear, burn spots, overheating, or “slip and grab”
causing belt breakage.
High belt tension causes belt heating and excessive
stretch, as well as damage to drive components such as
pulleys and shafts. V-belts should ride on the sides of
standard pulleys not on the bottom of the groove.
Standard V-belt tension can be checked with JDG529
Tension Gauge (arrow) or equivalent gauge.
1. Inspect belts for cracks, fraying, or stretched out
areas. Replace if necessary.
2. Using either JDG529 Tension Gauge or belt
tension tester and straightedge, check tension of
warm belts.
– For standard V-belt, an 89 N (20 lb. force)
applied halfway between pulleys should
deflect belt by 19 mm (3/4 in.).
3. If adjustment is necessary, loosen alternator bracket
cap screw and nut on mounting bolt. Pull
alternator frame outward until belts are correctly
tensioned.
IMPORTANT: Do not pry against the alternator rear
frame. Do not tighten or loosen belts while they are
hot.
4. Tighten alternator bracket cap screw and nut
firmly.
5. After a new or used belt has run for 10 minutes
recheck belt tension.

BATTERY GAS CAN EXPLODE. KEEP SPARKS
AND FLAMES AWAY FROM BATTERIES. USE A
FLASHLIGHT TO CHECK BATTERY
ELECTROLYTE LEVEL.
NEVER CHECK BATTERY CHARGE BY
PLACING A METAL OBJECT ACROSS THE
POSTS. USE A VOLTMETER OR HYDROMETER.
ALWAYS REMOVE GROUNDED NEGATIVE (-)
BATTERY CLAMP FIRST AND REPLACE IT
LAST.
1. On regular batteries, check electrolyte level. Fill
each cell to bottom of filler neck with distilled
water.
2. Keep batteries clean by wiping them with a damp
cloth. Keep all connections clean and tight.
