Modular hydraulic motors MS08 - MSE08 POCLAIN HYDRAULICS
INTRODUCTION
Given their optimized and modular design capable of delivering high performance, motors from the MS Classic range have established
themselves as a benchmark on the hydraulic motor market.
MS Classic range can be characterize by:
•Compacity
•Optimized cost
•Power density
The MS HighFlow™ motor range has all the qualities that have made the MS Classic range such a success: they are modular and robust, offering
performance advantages (speed and power) at the same time.
MS HighFlow™ motor range is different by:
•Integrated exchange valve
•New ports geometry
•New valving

The service life of the components is influenced by the pressure.You must check
that the combination of forces applied (Axial load / Radial load) is compatible with
the permissible loads for the components, and that the resulting service lives of
these components complies with the application's specifications. For an
accurate calculation, consult your Poclain Hydraulics application engineer.

The service life of the components is influenced by the pressure.You must check
that the combination of forces applied (Axial load / Radial load) is compatible with
the permissible loads for the components, and that the resulting service lives of
these components complies with the application's specifications. For an

To find the connections’ tightening torques, see the brochure
“Installation guide” N° B61352L.
Do not put either a check valve or a poppet valve on the pilot lines
(parking brake and displacement change) between the charge pump and
the pilot valve. Do not use a piloting valve with integrated check valve.

BRAKES
Rear brake
Do not run-in the multidisc brakes.
A functional check of the parking brake must be carried out each time it is used as an auxiliary brake
(or emergency brake). For all vehicles capable of speeds over 25 km/h, please contact your
Poclain Hydraulics application engineer.

Brake principle
This is a multidisc brake which is activated by a lack of pressure. The spring exerts a force on the piston, which presses on the fixed and
mobile discs, and immobilizes the shaft. The braking torque decreases in linear proportion to the brake release pressure.

3 - Brake environmental cover without plug
No plug or hole in the cover.
5 - Drainage
Fit an additional drain on the valving cover.
6 - Industrial support
Reduction of around 50% from the rated value in the bearings' preload value.
7 - Diamond™
Special treatment of the motor core which considerably increases its strength, making the motor much more tolerant to temporary instances of the
operating conditions being exceeded.
A - Hollow shaft

B - Drain on the bearing support
C - Abrasive environments (mechanical seal)
Certain environments can be very harmful. The mirror seal gives reinforced motor sealing.
E - Reinforced sealing
Requires reinforcement of shaft bearings.
G - Special wheel rim mounting
Enables certain combinations different from the standard mountings defined on pages 11 and 13.
H - High efficiency
Reinforced piston sealing to improve volumetric efficiency.
