Procedure to identify a
part
General
The modular design of Series 90 units results in a simplied service parts list and part
number identication procedure.
The same item numbers are used for same part names on all units within a product type.
(Example: The lip seal - Item L40 has the same item number on all pumps.)
A part number that has another number following it in parentheses is done to make this
a world wide manual. The rst number is sold in Germany. The number in parentheses
is sold in the United States. (Example: 001149 (9004201-6200), customers would order
9004201-6200 if ordering the part in the United States.)
Example of a Part Identification
The nameplate on a Series 90 pump has an Order Code of 90L180 MA 1 CD 80 S 3 F1 H 03
NNN 35 35 24. Use the following procedures to determine the part number of the drive
shaft used on this pump.
1) Referring to the input shaft module in the Order Code (see page 7), the input shaft
option for this pump is identied by the code “F1. (90L180 MA 1 CD 80 S 3 F1 H 03 NNN 35
35 24)
2) Referring to the Service Parts List, nd the shaft group. Next nd the order code that
relates to this unit, which is “F1”. The shaft is found to be item L100 and part number
11004306.

To improve eciency and reliability, the number of charge pump parts in the Series 90
180cc pump is being reduced. The charge pump design is being changed to make the
outer port plate an intergal part of the charge pump cover and to eliminate the distance
plates.
For auxiliary pad options, the new charge pump cover is rotation dependent. The cover will
be marked either left hand (L) or right hand (R). The non-auxiliary pad cover is not rotation
dependent.
The complete charge pump assembly can be interchanged with corresponding hardware.
However, piece parts are not interchangeable.

Side cover design change
As a product improvement, Sauer-Sundstrand is changing the side cover and swashplate
leveler (T-Bar) guide post design.
The new design side cover will have two hardened inserts in the machined slot which
serves as a guide for the swashplate leveler, and modied guide posts. The swashplate
leveler does not change.
Old guide posts will remain available for service requirements of pumps with the old design
side cover.
The old style side cover will be obsoleted and no longer available as a service part. A service
kit has been created for replacing the old design side cover. The kit includes the new side
cover, guide posts and inserts. Piece parts are not interchangeable..

Description
Series 90 75, 100, 130, 180, and 250cc variable displacement pumps
Hydraulic displacement control gasket and swashplate bearing locator pin retention
The Series 90 75cc, 100cc, 130cc, 180cc, and 250cc variable displacement pumps utilize
a common gasket to seal the joint between the displacement control housing and main
pump housing.
In November 1998, Sauer-Danfoss introduced a new gasket design for Hydraulic
Displacement Controls (HDC - all options), version 2 Electrical Displacement Controls
(EDC2 - options EE and EN), and two amp current control (options PA and PB) equipped
pumps (see SB-1998-038). The purpose of this gasket is primarily to seal the joint and
aid in the retention of the bearing cage locator pin in the main pump housing. SauerDanfoss has identied that the new gasket may not adequately aid in the retention of this
pin in 75cc pump sizes due to casting and machining tolerances. Installations which are
particularly sensitive to pin retention include those oriented with the control on the side
or on the bottom when the pump is installed. In these types of installations, it is possible
for the pin to come out of its position in the pump housing. This will result in a loss of
alignment between the swashplate and swashplate bearing assembly and the potential
for erratic pump control and/or system performance.
To address this situation, Sauer-Danfoss has introduced a design modication to the
control gasket. The modication will insure that the cage locator pin is retained in 75cc
pumps in all circumstances, while still maintaining the desired gasket clamp load to avoid
leaks.
Models affected
Serial numbers
The new gasket is completely interchangeable with the previous gasket. Sauer-Danfoss
recommends that the previous control gasket be replaced immediately on 75cc pump
assemblies, with controls noted above, in which the control is on the side or on the
bottom of the pump. The pump serial numbers involved are A-98-41-xxxxx through
A-99-49-xxxxx. It is not required to replace the gasket in pumps with the control in the up
position, until the initial servicing of the pump assembly.
The 100cc, 130cc, 180cc, and 250cc pumps are not dependent upon the gasket to
maintain retention of the bearing cage locator pin and are not aected by the information
above.
The new gasket has replaced the previous gasket in all new pump assemblies with
Hydraulic Displacement Control (HDC), version 2 Electrical Displacement Control (EDC2
- EE and EN), and two amp current (PA and PB) controls. The new gasket has also been
placed in all appropriate control kits and overhaul seal kits. Page 3 of this bulletin will
assist you in identifying the new gasket from the previous gasket.

992xxxx variable displacement pumps equipped with hydraulic displacement controls
and specic option electronic displacement control. (EE, EN, PA, PB)
As a product improvement, Sauer-Danfoss has changed the charge pump drive shaft.
This change will incorporate two drain holes in the shaft. These drain holes will prevent
pressure build up at the end of the pump input shaft. Relieving this pressure reduces the
axial load on the shaft and increases the life of the front roller bearing. The old charge
pump shaft part number will become obsolete and not available for service. The new
shaft is a direct replacement and can be used in older 180cc pumps.

Series 90 42, 130, 180 and 250cc variable pumps
SAE A auxiliary mounting ange, O-ring seal
Sauer-Danfoss is pleased to announce a design improvement on the SAE A auxiliary
mounting ange adapter on its series 90 pumps. The frame sizes aected by this change
are 42, 130, 180 and 250cc. All manufacturing locations producing these pumps will be
changed to this conguration.
The improvement comes in the form of a more robust sealing geometry with a larger
cross-section O-ring. The O-ring groove in the ange will now be sized to mate with a
2.62mm [0.103”] cross-section O-ring rather than the old 1.78mm [0.070”] cross-section
O-ring. The Sauer-Danfoss part number for the new O-ring is 9004104-1520 (2.62mm
[0.070”] x 82.22mm [3.237”]). The larger cross-section sealing geometry allows for the
use of a donut style A pad seal and a new at cover for improved assembly. This new
conguration is qualied as a running cover. When installing an auxiliary pump, the
donut style A pad seal must be discarded and the part number 9004104-1520 O-ring
used.
The pumps will now be supplied with the donut style seal and new at cover, instead of
the small O-ring and stepped cover plate (shown in the drawing below).

SAE C auxiliary mounting ange, O-ring seal
Sauer-Danfoss is pleased to announce a design improvement on the SAE C auxiliary
mounting ange adapter on its series 90 pumps. The frame sizes aected by this change are
130, 180 and 250cc. All manufacturing locations producing these pumps will be changed to
this conguration.
The improvement comes in the form of a more robust sealing geometry with a larger crosssection O-ring. The O-ring groove in the ange will now be sized to mate with a 2.62mm
[0.103”] cross-section O-ring rather than the old 1.78mm [0.070”] cross-section O-ring.
The Sauer-Danfoss part number for the new O-ring is 9004104-1580 (2.62mm [0.070”] x
120.32mm [4.737”]). The larger cross-section sealing geometry allows for the use of a donut
style C pad seal and a new at cover for improved assembly. This new conguration is
qualied as a running cover. When installing an auxiliary pump, the donut style C pad seal
must be discarded and the part number 9004104-1580 O-ring used.
The pumps will now be supplied with the donut style seal and new at cover, instead of the
small O-ring and stepped cover plate (shown in the drawing below).

Series 90 180cc variable pumps
Pump redesign
As a global improvement, the series 90 180/250cc pumps have redesigned the following
components: servo arm, servo arm screw, swashplate guide and pump housing. This is a
non-interchangeable change. Model numbers and order codes will not be changed.
A “one piece” servo arm is introduced. The pin that engages the servo piston is now
machined as part of the servo arm instead of pressed in. The old servo arm will remain
available as a service part for a period of time.
One of the two screws that hold the servo arm to the swashplate has changed from a M12
external hex to a M8 internal hex screw. The old screw will remain available as a service
part for a period of time.
The swashplate position is now guided by the t between the servo arm and the pump
housing. A “shelf” on the servo arm ts under a boss in the housing to provide a xed
clearance. The swashplate was previously held down with a spring and bracket, which was
riveted to the servo arm. The servo arm to housing clearance now limits lateral movement
of the swashplate. The swashplate guide that was bolted to the bottom of the swashplate
has been removed. The old swashplate guide will remain available as a service part for a
period of time.
The housing is modied internally to provide the servo arm pivot. The old housing will
remain available as a service part for a period of time.

Shaft seal change
A supplier change for the shaft seal used in Series 90 180 and 250cc pumps has been
made as part of globalization of the entire Sauer-Danfoss product line. The new lip seal
has a smaller O.D., and the I.D. of the seal carrier changed accordingly. The old lip seal and
seal carrier will become obsolete and not available for service.
The seal carrier assembly part number has changed to better track this change. The new
seal carrier assembly is interchangeable, but the piece parts are not.

Gerotor pin change
As an assembly aid, some of the charge pump gerotor pins used in 130, 180 and 250cc
pumps are being changed from one to two pins. This change is being made to reduce
the chance of mis-locating the pin in the end cap or gerotor cover during the assembly
process.
There will be three new lengths of pins used in these pumps. The new pin lengths will
be 16, 20 and 26mm. To aid in the identication of the new pins, the 20mm pins will be
yellow/gold in color.
