Engine belts

Fan and alternator belt

The belt- (1) that drives the cooling fan and alternator is

located at the front of the engine.

When 5 kg (11 lb) of pressure is applied midway between

the belt pulleys, a correctly tightened belt will deflect 5 mm

(0.2 in) .at point (A).

If the fan belt is slipping, fan efficiency is lowered, resulting

in the engine running too hot. or the alternator not charging

If the belt is too tight, the life of the alternator bearing will

be shortened. If the fan belt shows signs of cracking or

fraying, install a new one.

NHIL13CT01234AA

To adjust fan and alternator belt tension:

1. Loosen the two bolts (2) on the alternator , using a

prybar, pull the alternator away from the engine to

apply tension to belt.

2. When proper belt tension is achieved, tighten the

two alternator bolts.

Air pump belt

The belt (3) that drives the engine air pump is located at

the front of the engine.

When 5 kg (11 lb) of pressure is applied midway between

the belt pulleys, a correctly tightened belt will deflect

10 mm (0.4 in) .at point (B).

NHIL13CT01234AA

To adjust air pump belt tension:

1. Loosen air pump mounting bolt (4).

2. Rotate adjustment bolt (5) clockwise to tighten or

counterclockwise to loosen the belt tension.

7 - MAINTENANCE

Roll Over Protective Structure (ROPS) frame - Replace - Possible

damage

If the unit has rolled over or the ROPS has been in some

other type of accident (such as hitting an overhead object

during transport), the ROPS must be replaced to retain the

best protection.

Following an accident, check the ROPS, the operator's

seat, and the seat belt and seat belt mountings for pos-

sible damage. Before operating the machine, replace all

damaged parts.

NOTICE: Do not attempt to weld or straighten the ROPS.

Battery

The tractor is equipped with a BCI group 34, 12 V battery

with a minimum cold cranking ability of 660 A at -18 °C

(0 °F).

Make sure the battery connections are tight and free of cor-

rosion. A solution of baking soda and water may be used

to wash the outside surface and terminals of the battery

when necessary. However, make sure the solution does

not get inside the battery. After cleaning, wash the battery

with clean water, then apply a small amount of petroleum

jelly to the terminals to prevent corrosion.

In freezing temperatures, a good battery charge must be

maintained. If the battery becomes discharged or run

down, the electrolyte becomes weak and may freeze,

causing damage to the case.

NHIL13CT01160AA

7-37

7 - MAINTENANCE

Alternator

The tractor's 85 A alternator is belt-driven from the engine

crankshaft pulley. It is important that belt slippage does not

occur, or the charging system will be affected. To adjust the

belt, see 7-36.

Other than belt adjustment, the only alternator mainte-

nance required is to periodically inspect the terminals to

ensure they are clean and tight. The alternator cooling fan

should also be cleaned periodically.

When working on or checking the alternator, adhere to fol-

lowing precautions or alternator damage may occur:

• Do not UNDER ANY CIRCUMSTANCES short the

field terminal of the alternator to ground.

• Do not disconnect the alternator output lead or bat-

NHIL13CT01039AA

tery cables while the alternator is operating.

• Do not remove the alternator from the tractor with-

out first disconnecting the negative (-) battery cable.

When removing the battery, disconnect the negative

(-) cable first.

• To install a battery, MAKE SURE that the positive

(+) cable is connected first and that the negative ter-

minal is connected to ground. Reverse polarity will

destroy the rectifier diodes in the alternator.

If the battery charge warning light illuminates, indicating

that the alternator is not charging the battery, check the

fan belt and the wiring connections. If these items are in

satisfactory condition and the warning light continues to

indicate no charge, consult your New Holland Dealer.

necessary to prevent rust.

2. Check the tractor for worn or damaged parts. Install

new parts as required.

3. Raise the lift arms hydraulically to their fullest raised

position so that the lift piston is in a fully extended po-

sition. This fills the cylinder with oil and protects the

cylinder wall surfaces from corrosion.

4. Lubricate the tractor.

5. Fill the fuel tank with No. 1 diesel fuel.

NOTICE: Do not use No. 2 diesel fuel for winter storage

because of wax separation and setting at low temperature.

6. Open the drain valve of the radiator and engine block.

Flush the system, close the drain valves, and fill with a

50/50 solution of permanent antifreeze and clear water.

7. Remove the battery and clean it thoroughly. Be sure

that it is fully charged and that the electrolyte is at the

proper level. Store the battery in a cool, dry place

above freezing temperature, and charge it periodically

during storage.
