1.3.1 Spare parts
If it is necessary to replace a part, ask for and make sure that you use original spare parts only
Using non-original spare parts will void the warranty.
Always provide the following information when ordering spare parts:
- Tractor model and commercial name;
- Chassis number;
- Order code of required part (this can be found in the Spare Parts Catalogue).
1.3.2 Specific tools
The tools and equipment specified and illustrated in this manual have been developed specifically by the
manufacturer to make working on the tractor quicker, simpler and more effective.
These tools and equipment will ensure the best results possible with minimum operator strain, and let you
avoid any operations which could compromise the successful outcome of the job.
Note
The wear limits indicated are recommended only and not mandatory. The indications "front", "rear",
"right" and "left" are with respect to the operator facing towards the front of the vehicle and seated in
the drive seat.
1.3.3 Oil seals for rotating shafts
Observe the following precautions and instructions to ensure that oil seals are installed correctly:
- Clean the shaft thoroughly and check that the contact surfaces of the shaft itself are undamaged.
- Fit with the seal lip facing towards the fluid; when fitting hydrodynamic lip seals, the grooves must
be oriented correctly in relation to the direction of rotation of the shaft so that they will carry fluid
towards the interior of the seal.
- Spread a film of lubricant (preferably use oil and not grease) on the seal lip and, with double lip seals,
fill the gap between the oil seal lip and the dust seal lip with grease;
- Install the oil seal in its seat with a flat tipped punch; never hit the seal directly with a hammer.
- While installing the seal, make sure that the oil seal remains perpendicular relative to its seat. Once
the seal is installed, where applicable, check that it fits completely against the relative shoulder.
- To prevent the shaft from damaging the seal lip, place suitable protection between the two parts
during assembly.
1.3.4 Adjuster shims
Each time an adjustment with shims is necessary, measure each adjuster shim with a micrometer and
assemble a pack of the required thickness on the basis of the values measured.
Note
Do not rely on the measurement of the assembled pack and do not base your calculations on the
measurements indicated on each shim, as they may be incorrect.
