Z place the sealing lip towards the fluid. In case of a
hydrodynamic lip, consider the shaft rotation direc-
tion and orient grooves in order that they deviate
the fluid towards the inner side of the seal;
Z coat the sealing lip with a thin layer of lubricant (oil
rather than grease) and fill with grease the gap be-
tween the sealing lip and the dust lip of double lip
seals;
Z 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;
Z take care to insert the seal perpendicularly to its
seat while you are pressing it. Once the seal is set-
tled, ensure that it contacts the thrust element if re-
quired;
Z to prevent damaging the sealing lip against the
shaft, place a suitable protection during installa-
tion.
O-RINGS
Lubricate the O-rings before inserting them into their
seats. This will prevent the O-rings from rolling over
and twisting during mounting which will jeopardize
sealing.
BEARINGS
It is advisable to heat the bearings to 80 to 90 °C be-
fore mounting them on their shafts and cool them
down before inserting them into their seats with ex-
ternal 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 in-
stallation.
HARDWARE TORQUE VALUES
Check the tightness of hardware periodically. Use
the following charts to determine the correct torque
when checking, adjusting or replacing hardware on
the Backhoe loader.
IMPORTANT: Torque values listed are for general
use only. Make sure fastener threads are clean and
not damaged.
NOTE: a torque wrench is necessary to properly
torque hardware.
SECTION 01 - MAINTENANCE
NOTES FOR SPARE PARTS
Only genuine parts guarantee same quality, life,
safety as original components as they are the same
as mounted in production. Only the genuine spare
parts can offer this guarantee.
All spare parts orders should be complete with the
following data:
Z machine model (commercial name) and chassis
number;
Z engine type and number;
Z part number of the ordered part, which can be
found on the "Spare Parts Catalogue", which is the
base for order processing.
NOTES FOR EQUIPMENT
Equipment which proposes and shows in this man-
ual are as follows:
Z studied and designed expressly for use on compa-
ny machines;
Z necessary to make a reliable repair;
Z accurately built and strictly tested to offer efficient
and long-lasting working means.
We also remind the repair personnel that having
these equipment means:
Z work in optimal technical conditions;
Z obtain best results;
Z save time and effort;
Z work more safely.
CAUTION
Wear limits indicated for some details should be in-
tended as advised, but not binding values. The
words "front", "rear", "right hand", and "left hand" re-
ferred to the different parts should be intended as
seen from the operator's seat oriented to the normal
sense of movement of the machine.
HOW TO MOVE THE MACHINE WITH THE
BATTERY REMOVED
Cables from the external power supply should be
connected exclusively to the respective terminals of
the Machine positive and negative cables using pli-
ers in good condition which allow proper and steady
contact.
Disconnect all services (lights, wind-shield wipers,
etc.) before starting the Machine.
If it is necessary to check the machine electrical sys-
tem, check it only with the power supply connected.
At check end, disconnect all services and switch the
power supply off before disconnecting the cables.
