WarningsBefore Installation
During InstallationInstall the hydraulic system according to the specifications and processes appearing in this document.
After InstallationConsult repair documents for system and component maintenance and repair instructions.
Take all necessary safety precautions (people and machines) and comply with safety regulations in effect.
Confirm that mobile equipment is immobilized.
Confirm that the hydraulic systems energy generator (motor) is stopped and electric power is disconnected.
Lay out a safety perimeter.
Do not perform work on a hydraulic system that is hot or under pressure (discharge the accumulators).
Oil that is hot or under pressure can cause serious burns and infection. Consult a physician in case of accident.
Support the components using a lifting device whose capacity is adequate for attaching the components to the chassis.
During handling protect all sensitive surfaces from shocks (centerings, bolts, connectors, plugs, etc.).
Confirm that the components centering and support surfaces on the chassis are clean (free of paint).
Never heat hydraulic fluid which can ignite at high temperature. Some solvents are also inflammable.
Do not smoke while working on the system.
Do not over-size the safety valves.
Wearing in the motors is not necessary; full performance is reached after a few hours of operation.

Without oil.
Painted with primer.
With protected openings (Plastic/metallic plugs or plates with joints for the flanges, sealing them).
With protected attachment surfaces (these surfaces are never painted), they are covered with a thin film of varnish to limit any oxidation.
If the plugs are to remain in place while the motor is operating, the plastic plugs must be replaced by metal ones.

StorageThe motors are delivered in boxes. If they must be stored, leave them in the boxes.If this is not possible, follow the recommendations below in order to avoid damage to sensitive parts.
Storage IntervalDepending on the interval and storage conditions, it is necessary to protect the internal components of the hydraulic parts. These operations must be performed before storing components or before stopping use of the machine.
Watch out:If a motor falls during handling, it will have to be reconditioned before it is used.
Paint Leave the bearing surfaces unpainted. Use paints compatible with the existing base coat. When applying paint, protect the shafts lip seal. The paint could dry it and cause it to leak. The Poclain Hydraulics components (like any mechanical component) can rust. They must be effectively and regularly protected according
to the environment where they are used. During installation of the motors, any trace of rust must be eliminated before painting the machine.
Primer Specifications
Open air storage areas must not be used. The motors must not be placed directly on the ground.

PRODUCTSFIXATIONS
Attachment to the Chassis
Recommendations
Port 1 (motor case drain) must be located at the highest point when the motor is mounted. If this is not possible, the shape of the hose run must assure the motor case remains full of oil. Care must be used to avoid a siphoning effect if the motor is unused for a long period of time.
Refer to the specifications given in the technical catalog.
Unless absolutely flat, the motor chassis fixations may break.
The motor support surfaces must be clean (free of paint, grease, oxidation, etc.) in order for it to be properly mounted on the vehicle.

Attachments to the Shaft
Motor/Wheel Coupling
BoltsDuring mounting, the bolts must be new to comply with the tightening torques. The bolts must neither be greased nor degreased.
NutsCare must be taken during rim mounting to avoid contact with the bolts since this could damage the threads and which can change the fastener torque condition.
Refer to the specifications given in the technical catalog.
Greasing or degreasing of bolts may affect locking conditions and cause damage.
Take care to use nuts appropriate for the type of contact with the rim in order to obtain a proper mounting and tightening.
Use a torque wrench to comply with the predefined tightening torques.
Check the tightness of the wheel nuts: after 40 km. after 100 km. periodically.
Rubbing the wheel rim on the bolts must absolutely be avoided, since it could damage the threads and that modifies the tightening conditions.

Before engaging the pinion on the shaft, the splines must be checked for damage.
Lubricating the splines before mounting is recommend to make dismounting easier.
