SECTION 4 -- LUBRICATION AND MAINTENANCE

ACCESS FOR

INSPECTION AND MAINTENANCE

INTRODUCTION

To access the engine components and carry out

inspection, lubrication and maintenance operations,

the bonnet (hood) must be opened.

The following instructions describe the procedure to

be followed.

1

BONNET (HOOD)

1

The bonnet is hinged at the rear to allow easy and

safe access to the various engine components.

One gas strut (1) fig. 2 holds the engine bonnet in

one of the two possible positions.

TRE0046A

2

OPENING THE BONNET (HOOD)

Pull the lever upwards (1) fig. 3, lift from the front, and

allow the bonnet to raise. The gas strut (1) fig. 2 will

1

maintain the bonnet in the raised position.

NOTE: To close the bonnet, simply pull it down and

press the top lightly to ensure it engages.

FLEXIBLE MAINTENANCE

OPERATION 1

1

CLUTCH ADJUSTMENT -- Figs. 1 and 2

If the clutch pedal position is uncomfortable (too

high) or it will not reach its upper rest position (to

prevent the clutch slipping) check that distance A, on

A

clutch pedal (1) fig. 1 is 35--40 mm (1.4--1.6 in) if not,

adjust the pedal as follows:

--

Release lock nuts (1) fig. 2 and turn hexagon

1

sleeve (2) anti--clockwise;

--

Check that distance A corresponds with the

value given above;

--

Tighten lock nuts (1) fig. 2;

--

Re--check that the pedal travel is as specified.

1

2

CAUTION

2

The distance must be measured from the pedal

centre as shown in fig. 1.

OPERATION 2

BRAKE PEDAL ADJUSTMENT -- Fig. 3-- 4

Adjusting height of service brake pedals

--

With the brake pedals connected to their

respective forks and the pedal connecting pin

released, check pedal adjustment.

A

--

Check that pedal free travel (A) is the same for

each pedal and does not exceeds 80 mm.

3

4--7

SECTION 4 -- LUBRICATION AND MAINTENANCE

--

If adjustment is required, fully release the

handbrake (lever down). Slacken the lock nuts

1

(1) and turn the hexagon sleeves (2) until brake

2

pedal free travel is 5 mm. Finally, tighten the lock

nuts (1).

4

OPERATION 3

FAN BELT (ALL VERSIONS WITHOUT

AIR--CONDITIONING) -- Fig. 5

A

Check that tension (A) at the centre of the belt run,

as shown in the figure, is 10--11 mm (0.39--0.43 in)

with

an applied load of

78--98

N

(8--10 kg or 17.7--22.1 lbs).

1

To adjust, slacken screw (1) and reset the tension to

the values indicated above.

NOTE: If the belt is cracked or frequent adjustment

TRE0830A

is necessary, it needs to be replaced.

5

OPERATION 4

COMPRESSOR BELT -- Fig. 6

Check that tension (A) of the belt shown in the figure, is

2

12--13 mm (0.47--0.51 in) with a load of

78--98 N

(8--10 kg or 17.7--22.1 Ibs), measured in the centre of

the belt run, as illustrated in the figure.

To adjust, slacken screw(1) and adjust belt tensioner (2).

NOTE: If the belt is cracked or frequent adjustment

is necessary, it needs to be replaced.

Check if the outlet valve (1) is clogged by squeezing

the rubber end cap to allow accumulated dust to

escape.

WHEN THE WARNING LIGHT IS ON

DRY AIR FILTER MAINTENANCE -- Fig. 8

NOTE: Always take corrective action, as follows in

Operation

6, when the red indicator light

(1)

illuminates, indicating that the airflow through the

filter is restricted.

Replace the external element every year, or when pin

holes appear (visible by placing a light inside). Do not

clean the internal safety element (by blowing or

1

washing) but replace annually or whenever the

TRE0073A

external element is replaced.

8

OPERATION 6

MAIN DRY AIR FILTER CARTRIDGE --

Fig. 9

When the red indicator light in the instrument panel

illuminates, remove the cover, extract the outer

element (1) and clean as follows:

--

with a jet of compressed air at less than 5.9 bar

(6 kg/cm²) (85 Psi), insert the air line nozzle

inside the element and blow dust from the inside

through the element to the outside;

or

--

with water and non--foaming detergent, rinse

with a water jet at less than 2.9 bar (3 kg/cm²)

(42 Psi) and dry with dry air at a temperature of

less than 50_C. Do not re--install the element

unless it is perfectly dry. A damp air cleaner

element will rupture when the engine is started.

Never clean the element by tapping it on a hard

9

surface. Instead, tap it on the palm of your hand.

Clean the whole of the inside of the container

carefully with a damp cloth.

Do not disturb the inner safety element.

--

Place a thermometer next to the vents (arrowed

in the fig. 24) and check that the temperature

measured is around 15^o C less than the external

temperature.

or

--

Check, with the air--conditioning on, that

inspection glass (1) fig. 23, on top of the filter, is

transparent; if white liquid or air bubbles can be

seen, the filter needs to be replaced.

AMBRA AGRIFLU to water

61

Your tractor is supplied with the cooling system filled

with an Ambra Agriflu solution appropriate to your

climatic conditions. This will guarantee the system

down to the temperature shown on the plate attached

to the bonnet.

This mixture will protect the cooling system for a

period of 2 years provided that during this time the

tractor has not been used for more than 1200 hours

in total. Flush the system and replace the anti--freeze

mixture when either of these limits have been

reached.

In emergencies, to prevent overheating, fill the

system by pouring water into the radiator opening (1)

fig. 63.

WARNING

Repair any damage and top up the mixture as soon

GENERAL MAINTENANCE

BLEEDING THE FUEL SYSTEM

Bleeding procedure -- Figs. 68 and 69

During long periods when the tractor is not used,

when the filter and fuel lines are removed or when

there is no fuel in the tractor, air may enter the fuel

system.

The presence of air makes it difficult to start the

engine and it therefore needs to be bled as follows

when the fuel tank is refilled:

1. Unscrew the bleed plug

(1) fig. 68

by

approximately two turns.

68

2. Actuate lever (1) fig. 69 until fuel without air

bubbles spurts from the bleed hole.

3. Tighten plug (1) fig. 68.

4. After tightening the bleed plug (1) fig. 68, actuate

lever (1) fig 69 a few times.

5. Turn the ignition key to position C, as shown in

Section 2, fig.

18, page 2--11. As soon as the

engine starts, release the key.

1

NOTE: Your engine is fitted with a rotary injection

pump, whose internal components must be

protected from rusting if not used for over a month.

23731A

Therefore, before stopping the tractor, mix PROT 10

W/M oil with the fuel in the tank in a proportion of

69

10% and run the engine for approximately half an

hour.

BLEEDING THE HYDRAULIC BRAKE

SYSTEM

Bleeding procedure -- Figs. 70 to 73

Whenever work is carried out on the front brake hy-

draulic system, the air must be bled from the system.

Proceed as follows.

1. Thoroughly clean the external parts of the unit

around the hydraulic fluid tank cap (2) fig. 70 and

the bleed screws (1--2) fig.

71.

2. Make sure that the hydraulic fluid in the tank (1)

70 is maintained up to the full mark both before

and during the bleeding operations.
