Date Code

The date code is defined as the year and week of manufacture. The same reference number may list more than onepart number. This indicates that there is more than one configuration for that reference number. You will see that thereare different date codes for the different part numbers. Find the date code of your unit via the nameplate to determinewhich service part number you need to order.

EXAMPLE: The service part desired is Item G302.

Order Date Code Qty. perCode Item Begin → End Part Number Description Model

2 G302 89-46 → 8200212 End cap gasket (SB-9203) 1“ 87-02 → 89-45 8200043 End cap gasket (SB-8923) 1

All units using this module group with a date code of 87-02 and up to and including 89-45 must use part number“8200043”. All units with a date code of 89-46 and up must use part number “8200212”.

Service Bulletins

A Service Bulletin Number (SB- _ _ _ _) may follow the “Description” of the part you desire. You must read thatService Bulletin prior to ordering that part. A copy of each of these Service Bulletins, as of the print date of thisbulletin, are included at the end of this manual. Service Bulletins contain more detailed information such asinterchangeability, what additional parts are involved, etc. It is suggested that you add additional Service Bulletinsto this manual as you receive them.

Procedure to Identify a Given Part/Part Number

GeneralThe modular design of Series 90 units results in a simplified Service Parts List and Part Identification Procedure.

The same item numbers are used for same part description on all units within a product type. (Example: The shaft seal- Item Number L40 has the same item number on all variable displacement pumps.)

All Item Numbers begin with a letter. The letter identifies a particular module. (Example: any items beginning with “K”relate to the charge relief valve; items beginning with “L” relate to the drive shaft components, etc.)

Example of a Part Identification

The nameplate on a Series 90 pump has an Order Code of 90L100 EP 1 V 6 P 3 S4 E 05 NNN 38 38 20. Use thefollowing procedures to determine the part number of the filtration kit used on this pump.

1) Referring to the filtration module in the Model Code (see page 5), the filtration option for this unit is identified bythe code “P” (90L100 EP 1 V 6 P 3 S4 E 05 NNN 38 38 20)2) Referring to the Service Parts List, find the filtration group. Next find the order code that relates to this unit, whichis “P”. The filtration kit is found to be item N00M and part number 8002N00M-A. Also note that the saleable partsincluded in this kit are indented, which indicates the filter is not included in the kit.

To improve efficiency and reliability, the number of parts in Series 90 pumps

is being reduced. The charge pump design on 55cc thru 130cc frame sizes

is being changed so that the outer port plate is an integral part of the charge

pump cover and distance plates are eliminated. The change is taking effect

at the following manufacturing dates:

55cc: 93-10 75cc: 93-10 100cc: 93-15 130cc: 93-34

For auxiliary pad options, the new charge pump cover is rotation dependent.

The cover will be marked as either left hand (L) or right hand (R). The non-

axiliary pad cover is not rotation dependent.

The charge pump shaft also changes and must be replaced when using the

new style hardware. The complete charge assembly can be interchanged

with corresponding hardware from 89-17 and beyond. However, piece

parts are not interchangeable. For units prior to 89-17, consult Sauer-

Sundstrand.

The old design charge pump hardware is obsolete and is no longer available.

Refer to the chart on the reverse side of this page to determine the

replacement kit.

DESCRIPTION:

PRODUCTS AFFECTED: Series 90 PumpsSUBJECT: Servo Arm Change

As a product improvement, Sauer-Sundstrand has changed the Series 90 Pump servo armand swashplate (items D10 and D50). The old style servo arm and swashplate will becomeobsolete. Because this change creates non-interchangeability between new and oldswashplates, servo arms, and possibly servo pistons (item S10) and slider blocks (itemF20), separate servo arms and swashplates will no longer be sold as spare parts.

Also, the new servo arm is actually a press fit into a groove in the new swashplate. Thissituation requires special tooling for assembly, therefore, pre-assembled kits will be createdfor 55, 75, and 100 cc pumps. The kits will work in any vintage pump.

The kit for 55 cc pumps will include all the items in the figure, except item S10.

The kit for 75 cc pumps will include all the items in the figure.

The kit for 100 cc pumps will include all the items in the figure, except items S10 and F20.

NOTE: The slider block (item F20) in 55 cc pumps and the slider block and the servo piston(item S10) in 75 cc pumps had to be changed slightly to allow clearance for the newservo arm. The new part number servo piston and slider blocks will work in anyvintage pump.

PRODUCTS AFFECTED: Series 90 PumpsSUBJECT: Change in Fixed Slipper Hold Down

As a product improvement, Sauer-Sundstrand has simplified the design of the Series 90 Pumpslipper hold-down mechanism. The hold-down changes from spring loaded with a fixedmaximum clearance to a fixed clearance design.

The leaf spring (item C60) and spring aligner (item C66) will be eliminated and will not beavailable as spare parts.

The spacer (item C50), bearing (item C40), and washer (item C65) will change and the old partnumbers will not be available as spare parts.

The swashplate (item D50), pistons (item C20), slipper retainer (item C30), and screws (itemC70) will remain the same.

If any of the affected parts (items C66, C60, C65, C50, or C40) require replacement duringrepair of older style pumps, discard these parts and rebuild using new style parts (items C40,C50, and C65). As before, the screws (item C70) which are coated with locking compoundMUST always be replaced after removal.

Service Bulletin SB-8823PRODUCTS AFFECTED: Series 90 Pumps and MotorsSUBJECT: Piston Improvement

DESCRIPTION:

Product Information Bulletin PIB-8801 (March, 1988) announced the incorporation offabricated (welded) piston assemblies, replacing non-fabricated (hollow) piston assemblies,in the cylinder blocks of all Series 90 pumps and motors. This change increases the overallefficiency of the Series 90 product line.

To simplify service parts inventory for all Series 90 units, only individual welded pistonassemblies will be available as service parts. The hollow pistons will be obsoleted. Partnumbers for INDIVIDUAL welded piston assembies are listed on the back side of thisbulletin.

Since all Series 90 pumps and motors have nine (9) pistons, welded pistons being used toreplace hollow pistons during repair MUST be installed in the cylinder block symmetrically,in multiples of three (3).

Welded PistonAssembly

Hollow PistonAssembly

When replacing hollow pistons with welded pistons, it is mandatory that the weldedpistons be incorporated symmetrically in multiples of three (3).

NOTICE

The initial issue of this bulletin (dated 12/19/88) did not include an incorporation date. This revisionis being distributed to inform all users of the exact incorporation date. You may remove the initialissue of this bulletin from your files.

DESCRIPTIONThe configuration of the Remote Pressure Filtration Adapter, available as an option on Sauer-Sundstrand Series 90 Variable Pumps (55, 75, and 100 cc) is changing. This improved designadapter incorporates a charge pressure test port. In addition, the remote filter connections havebeen relocated to improve the customer interface and the routing for filter plumbing on mostapplications. Port sizes did not change. (A version of the improved design adapter is already beingused on Series 90 42 cc Variable Pumps.)This change does not affect the pump end cap, and either design filtration adapter can be used onany vintage pump. Only the new style adapter will be available as spare parts or on new productionpumps.The outline dimensional differences between the new and old adapters are shown below.

Adjusting Charge Relief Valve Charge Relief Valve Assembly

As a product improvement, Sauer-Sundstrand is incorporating an externally adjustable chargerelief valve on all Series 90 variable displacement pumps. This design replaces the previous shimadjustable charge relief valve. The new design valve provides a range of pressure adjustmentwhich covers the available charge pressure options of 290, 348, and 406 psi (20, 24, and 28 bar).

NOTE This improvement changes the design of the charge relief valve poppet and plug. The newstyle charge relief valve may protrude from the pump end cap approximately 0.27 in. (6.9mm) farther than the shim adjustable design.

To adjust the new design valve, first install gauges to measure charge pressure and case pressureas described in the Series 90 Service Manual. Loosen the adjustment lock nut with a 1-1/16 in. hexwrench. Operate the pump at an input speed of 1700 to 2000 rpm and turn the adjustment nut witha large screwdriver while observing the charge pressure and case pressure. Clockwise (CW)rotation of the plug increases the setting, while counterclockwise (CCW) rotation decreases thesetting (at a rate of approximately 50 psi [3.4 bar] per turn). Charge pressure settings arereferenced to case pressure. Once the desired setting is achieved, torque the lock nut to 34 to 41lbsf•ft (46 to 55 Nm) and remove the gauges.

Sauer-Sundstrand will offer an adjustable charge relief valve kit for sale as a spare part. This kitcan be used to service any vintage Series 90 variable pump. Since the new and old style chargerelief valves are interchangeable as an assembly, the old style parts will be made obsolete and willno longer be available as spare parts.

DESCRIPTION:

PRODUCTS AFFECTED: Series 90 PumpsSUBJECT: Swashplate Leveler Spring Seat Change

and Servo Pressure Relief Valves

As a product improvement, Sauer-Sundstrand is adding hardened shims between theswashplate leveler springs and the end cap in Series 90 variable displacement pumps. Inaddition, the leveler spring seats have been hardened, and are now separate pieces fromthe leveler. Previously, the seats were peened to the leveler.

These improvements requier some minor changes in the repair procedures for the Series90 pumps. When installing the leveler springs (item E80), take care that the spring seats(item E22) are in position on the swashplate leveler. Before installing the end cap, assemblethe hardened shims (item E24) into their poskets in the end cap and retain with petroleumjelly.

The swashplate leveler, plus the separate spring seats, is directly interchangeable with theold design part. When performing major repairs on any Series 90 pump, the hardened shimsshould be installed between the leveler springs and the end cap.

In an unrelated change, the servo pressure check (relief) valves (item P70) installed in thepump end cap (or rotation valve housing) were replaced by standard internal hex, straightthread O-ring plugs in some pumps. The servo pressure check (relief) valves MUST beinstalled in pumps equipped with pressure limiters in order to provide maximum end capgasket life.

DESCRIPTION:

The original design Series 90 charge pump assembly included two (2) port plates, one (1)on each side of the gerotor. If the charge pump displacement was less than the maximumavailable for the pump’s frame size, the inside port plate was thicker than the 0.050 in. (1.27mm) outside port plate.

The new design charge pump will always have two (2) 0.050 in. (1.27 mm) thickness portplates, one (1) on each side of the gerotor. Additionally, if the charge pump displacementis less than the maximum available for the pump’s frame size, one (1) or two (2) spacerswill be installed between the outside port plate and the charge pump cover.

In addition, the location of the keyway in the charge pump shaft has also been changed toensure full engagement of the drive key in the gerotor. The new charge pump shaft usedin 75 cc and 100 cc frame size pumps has two (2) keyways. The rear keyway (farthest fromthe end cap and splined end of the shaft) is used for 75 cc pumps, while the front keyway(closest to the end cap and splined end of the shaft) is used for 100 cc pumps. The new stylecharge pump shafts for 55, 75, and 100 cc pumps also changed from having a beveled endto a square end on the end of the shaft closest to the pump end cap.

DESCRIPTION:

Series 90 Pumps - 55cc thru 100cc

Charge Pump Design Change

The serial numbers mentioned on the reverse side of this page apply only to Amesproduction units. Neumunster will incorporate the change in July or August of thisyear. A service bulletin will follow when the exact dates are known.

To improve efficiency and reliability, the number of parts in Series 90 charge pumps is beingreduced. The charge pump design on 55cc thru 100cc frame sizes is being changed suchthat the outer port plate (H30) is an integral part of the charge pump cover (J15) and distanceplates are eliminated.

For auxiliary pad options, the new charge pump cover is rotation dependent. The cover willbe marked either left hand (L) or right hand (R). The non-auxiliary pad cover is not rotationdependent.

The charge pump shaft also changes and must be replaced when using the new stylehardware. The complete charge pump assembly can be interchanged with correspondinghardware from89-17 and beyond. However, piece parts are not interchangeable . For units prior to 89-17, consult Sauer-Sundstrand.

PRODUCTS AFFECTED: Series 90: 55,75,100, 130 cc PumpsSUBJECT: Block Point Change: Components Redesign

DESCRIPTION:

As part of our overall Series 90 product improvement program, numerous compo-nents are being redesigned. This redesign is referred to as a “blockpoint” change. Theobjective of the blockpoint change is to minimize the number of times we change the unitswhile we convert to high volume tooling at various plant sites. These design improvementswill provide increased reliability and more application flexibility. The nature of these changesmakes customer requalification unnecessary. Old style (pre-block point) variable housingsand end caps will no longer be available as spare parts.

NOTE: This Service Bulletin revision adds the 042 cc Frame Size and the incorpora-tion date of the 055 through 100 cc.

A potential interference problem has been identified in Series 90 042, 055, 075, and 100frame size pumps built since early 1992. Interference may occur between the swashplatehold down bracket on the servo arm and the speed sensor ring, which may be installed onthe cylinder block as an option.

A new hold down bracket has been designed to provide clearance for the speed sensor ring.

If a cylinder block with speed sensor ring must be installed in one of the subject pumps, aservo arm assembly with the new style hold down will also be required.

Sometime during the first quarter of 1994, all 055, 075 and 100 cc pumps will be equippedwith the new design hold down bracket. The 042 cc pumps will implement the new designhold down bracket in the second quarter of 1994. A revision to this bulletin will be issuedwhen exact incorporation date is known.

Silver Pulse Pick-up Body

A small number of pulse pick-ups used on pumps and motors between June 1992 and April1994 have been found to be defective due to corrosion of internal circuitry.

The corrosion of the internal circuitry may cause intermittent operation or partial loss ofsignal and eventual failure.

A typical installation of a pulse pick-up is pictured below. Note the "silver" color of thepotentially defective pulse pick-up body. This should be replaced with a pulse pick-up bodythat is "black" in color.

NOTE: If your speed sensor is in an electrical closed loop feedback circuit, possibly usedwith a microprocessor, the silver colored speed sensor must be changed regardless of thespecial hardware features code.

Series 90 Pumps - All Frame Sizes

Manual Displacement Control (MDC) with DC Electric Solenoid Override

In order to accomodate our European customers, the manifold which attaches to the frontof the manual displacement control (MDC) housing is being changed.

The European solenoid valve requires a thicker manifold to provide clearance betweenthe solenoid and the front of the MDC housing. The revised manifold will protrude closerto the mounting flange of the pump, reducing dimension "A" shown in the accompanyingdrawing by approximately 5 mm [0.2 in]. Please see chart below for specific clearances.

The thicker manifold requires longer screws and may be used with either the U.S. orEuropean sourced solenoid.

This change will become effective during March of 1995. The old manifold will beobsoleted and no longer available as a service part.
