WARNING
All maintenance and repair work described in
this manual must be performed exclusively by
NEW HOLLAND service technicians in strict
accordance with the instructions given and
using any specific tools necessary.
WARNING
Anyone who performs the operations described
herein without strictly following the instructions
is personally responsible for resulting injury or
damage to property.
WARNING
The Manufacturer and all organizations belong-
ing to the Manufacturer’s distribution network,
including but not restricted to national, regional
or local distributors, will accept no responsibility
for personal injury or damage to property caused
by abnormal function of parts and/or compo-
nents not approved by the Manufacturer,
including those used for maintenance and/or
repair of the product manufactured or marketed
by the Manufacturer. In any case, the product
manufactured or marketed by the Manufacturer
is covered by no guarantee of any kind against
personal injury or damage to property caused by
abnormal function of parts and/or components
not approved by the Manufacturer.

GENERAL INSTRUCTIONS
IMPORTANT NOTICE
All maintenance and repair operations described in
this manual should be carried out exclusively by the
authorized workshops. All instructions detailed
should be carefully observed and special equipment
indicated should be used if necessary.
Everyone who carries out service operations
described without carefully observing these prescrip-
tions will be directly responsible of deriving
damages.
SHIMMING
At each adjustment, select adjusting shims, measure
them individually using a micrometer and then sum
up recorded values. Do not rely on measuring the
whole shimming set, which may be incorrect, or on
the rated value indicated for each shim.
ROTATING SHAFT SEALS
To correctly install rotating shaft seals, observe the
following instructions:
• Let the seal soak into the same oil as it will seal
for at least half an hour before mounting;
• Thoroughly clean the shaft and ensure that the
shaft working surface is not damaged;
• Place the sealing lip towards the fluid. In case of
a hydrodynamic lip, consider the shaft rotation
direction and orient grooves in order that they
deviate the fluid towards the inner side of the
seal;
• Coat the sealing lip with a thin layer of lubricant
(oil rather than grease) and fill the gap between
the sealing lip and the dust lip of double lip seals
with grease;
• Insert the seal into its seat and press it down
using a flat punch. Do not tap the seal with a
hammer or a drift;
• Take care to insert the seal perpendicularly to its
seat while you are pressing it. Once the seal is
settled, ensure that it contacts the thrust element,
if required;
• To prevent damaging the sealing lip against the
shaft, place a suitable protection during
installation.
O RINGS
Lubricate the O rings before inserting them into their
seats. This will prevent the O rings from roll over and
twisting during mounting, which will jeopardize
sealing.
SEALERS
Apply silicone/gasket eliminator over the mating
surfaces marked with an X.
Before applying the sealer, prepare the surface as
follows:
• remove possible scales using a metal brush;
• thoroughly degrease the surfaces using one of
the following cleaning agents: trichlorethylene,
diesel fuel or a water and soda solution.
BEARINGS
It is advisable to heat the bearings to 80° to 90°C
(176° to 194°F) before mounting them on their shafts
and cool them down before inserting them into their
seats with external tapping.
SPRING PINS
When mounting split socket spring pins, ensure that
the pin notch is oriented in the direction of the effort
to stress the pin.
Spiral spring pins should not be oriented during
installation.
