Introduction
Use of this Manual
S90MVCTCD
S90PVMFCD
This manual includes information for the normal opera-
tion, maintenance, and servicing of the Series 90 family
of hydrostatic pumps and motors.
The manual also includes the description of the units and
their individual components, troubleshooting informa-
tion, adjustment instructions, and minor repair proce-
dures. Unit warranty obligations should not be affected if
maintenance, adjustment, and minor repairs are per-
formed according to the procedures described in this
manual.
Many service and adjustment activities can be performed
without removing the unit from the vehicle or machine.
However, adequate access to the unit must be available,
and the unit must be thoroughly cleaned before beginning
maintenance, adjustment, or repair activities.
Since dirt and contamination are the greatest enemies of
any type of hydraulic equipment, cleanliness require-
ments must be strictly adhered to. This is especially
important when changing the system filter and during
adjustment and repair activities.
For further information refer to Series 90 Technical
Information. For information about fluid requirements
refer to SAUER-SUNDSTRAND BLN 9887 or SDF (Id No.
697581).
A worldwide network of SAUER-SUNDSTRAND Autho-
rized Service Centers is available should repairs be
needed. Contact any SAUER-SUNDSTRAND Autho-
rized Service Center for details. A list of all Service
Centers can be found in bulletin BLN-2-400527, or in
brochure SAW (Ident. No. 698266).
Fluid under High Pressure
Safety Precautions
Observe the following safety precautions when using and servicing hydrostatic products.
Flammable Cleaning Solvents Disable Work Function
Loss of Hydrostatic Braking Ability
WARNING
The loss of hydrostatic drive line power in any
mode of operation (e.g., forward, reverse, or "neu-
tral" mode) may cause the loss of hydrostatic
braking capacity. A braking system, redundant to
the hydrostatic transmission must, therefore, be
provided which is adequate to stop and hold the
system should the condition develop.
S000 001E
WARNING
Use caution when dealing with hydraulic fluid
under pressure. Escaping hydraulic fluid under
pressure can have sufficient force to penetrate
your skin causing serious injury. This fluid may
also be hot enough to burn. Serious infection or
reactions can develop if proper medical treat-
ment is not administered immediately.
S000 003E
WARNING
Some cleaning solvents are flammable. To avoid
possible fire, do not use cleaning solvents in an
area where a source of ignition may be present.
S000 004E
WARNING
Certain service procedures may require the ve-
hicle/machine to be disabled (wheels raised off
the ground, work function disconnected, etc.)
while performing them in order to prevent injury
to the technician and bystanders.
