STANDARD HYDRAULIC SYSTEMS ON THE DOMESTIC SERIES 7000: ORIENTATION NOTE: Subsections 1 and 2 of the Domestic Series 7000 Hydraulics portion of this manual provide a basic orientation to the system. Subsection 3 and those that follow it contain specific test procedures. The hydrostatic drive is a Sauer model BDU15.
www.mymowerparts.com Domestic Series 7000 Hydraulics 1.7. 1.11. The hydraulic fluid flow is as follows: The steering pump, located in the dash pedestal contains it’s own back-up gerotor charge pump that will enable steering control when the engine is not running. See Figure 1.7. 1.12. Through the pick-up tube from the transmission sump and filter, to the auxiliary pump. See Figure 1.12. Auxiliary pump Steering pump Flow Filter Figure 1.7 Figure 1.12 1.8.
www.mymowerparts.com Domestic Series 7000 Hydraulics 1.14. The steering unit distributes pressure to the steering cylinder according to the position of the steering wheel. On Sauer pumps this involves the ports labeled “L” and “R”. See Figure 1.12. 1.16. The power steering unit is first in line, and has priority over the rest of the system. From the steering unit, the fluid may follow one of two return paths: 1.17.
www.mymowerparts.com Domestic Series 7000 Hydraulics 1.19. If the fluid is required by the lift cylinder, it will go to the bottom port of the lift valve instead of the return manifold. 1.20. The lift valve sends fluid to the single-acting lift cylinder when operator demand and the feedback rod direct it to do so. See Figure 1.20. 2. HYDROSTATIC DRIVE: BASIC OPERATION 2.1. The input shaft to the D15U turns a shaft that passes completely through the housing of the hydro.
www.mymowerparts.com Domestic Series 7000 Hydraulics 2.4. The lower part of the pump contains a fixed displacement axial piston hydraulic motor. The motor is driven by the output of the variable displacement pump. 2.5. The hydro. control arm (scissors bracket) moves a swash plate that controls the output of the pump: tilting the swash plate in one way causes the variable displacement pump to drive fluid through the fixed displacement pump in one direction. See Figure 2.5. Variable displacement pump 2.6.
www.mymowerparts.com Domestic Series 7000 Hydraulics 3. 3.3. EXTERNAL CHECKS NOTE: Linkage adjustment procedures are covered in the 2003 Cub Cadet Technical Handbook, pages 6-129 through 6-131. 3.1. If the brake and drive pedals “fight” with each other, the drive control linkage is out of adjustment. See Figure 3.3. Brake shaft assembly Remove the fender cover using a phillips head screwdriver and a 1/2” wrench. See Figure 3.1.
www.mymowerparts.com Domestic Series 7000 Hydraulics 3.5. If there is no drive at all, confirm whether the problem lies in the hydro or elsewhere. • With the engine running, confirm that the PTO operates when it is turned-on. This confims that the input shaft is turning. • On smooth, firm, level ground, with the engine turned-off and the parking brake released: • Place the gear selector in high range and attempt to push the tractor. It should not roll.
www.mymowerparts.com Domestic Series 7000 Hydraulics 4. BEST PRACTICES: HYDRAULIC SYSTEMS NOTE: TESTS All hydraulic tests should be done with the fluid at normal operating temperature, and the engine at normal operating speed. In practical terms, normal operating temperature means that the tractor should be operated (if not disabled) for about 5 minutes before testing in normal temperate climates. This should achieve a fluid temperature of 180 deg. f. (82 deg. c.
www.mymowerparts.com Domestic Series 7000 Hydraulics 5.4. The charge pump should generate between 70 and 150 PSI (4.8 to 10.3 Bars) @ 1,200 RPM. See Figure 5.4. 5.7. Assuming the supply to the pump is good, low pressure or a complete lack of pressure at this port indicates a charge pump that is not working. 5.8. The charge pump could be disabled by a sticking charge pump relief valve. See Figure 5.8. Figure 5.4 5.5. Figure 5.
www.mymowerparts.com Domestic Series 7000 Hydraulics 5.9. 5.11. When removed, each charge relief valve comes out as a cartridge. See Figure 5.11. If the charge pump is working, but drive has been lost in one direction only, one of the charge check valves may not be working. See Figure 5.9. Charge check valves Figure 5.11 Figure 5.9 • There is a charge relief valve located in each circuit: one for forward, one for reverse.
www.mymowerparts.com Domestic Series 7000 Hydraulics 6. AUXILIARY PUMPS 6.1. The standard auxiliary pump provides pressure for the hydrostatic power steering unit and the lift cylinder attached to the three-point hitch. 6.2. Domestic Series 7000 tractors produced before the 2004 season came with a single auxiliary pump. See Figure 6.2. Auxiliary pump to drive steering and lift cylinder Hydraulic pressure to steering unit 6.5.
www.mymowerparts.com Domestic Series 7000 Hydraulics 6.7. 6.11. The rear fenders must be removed to access the auxiliary pump itself. Fender removal is detailed in the 2003 Cub Cadet Technical Handbook on pages 6-21 through 6-27. If the tractor has a speed sensor mounted in the transmission cover, it is a hall effect device that employs the auxiliary pump drive gear as a tonering to generate a tachometer signal. This was done on early (2003 production) tractors. See Figure 6.7. 6.12.
www.mymowerparts.com Domestic Series 7000 Hydraulics 6.16. Disconnect the output line from the top of the pump using a 3/4” wrench and a 9/16” wrench. • 6.17. Install the gauge set in-line between the auxiliary pump and the steering pump. The pressure gauge should be near the auxiliary pump, and the flow meter should be near the steering unit. Set the throttle to maintain an engine speed in this range, and note the reading on the flow meter. 6.21.
www.mymowerparts.com Domestic Series 7000 Hydraulics 7. STEERING PUMP AND CYLINDER • 7.1. Two steering units have been used in domestic Series 7000 production: one produced by Sauer/ Danfoss, and one produced by Ross (ParkerHannifin). Cause 1: The auxiliary pump is not supplying sufficient fluid to the steering unit. Confirm by testing auxiliary pump out-put. Solution 1: Correct the problem with the auxiliary pump.
www.mymowerparts.com Domestic Series 7000 Hydraulics • • Shimmy: Cause 1: Air in steering system. The Steering Wheel Does Not Return to Center: Cause 1: There is a mechanical bind in the steering column. Solution 1: Repair any leaks in the hydraulic system. Be aware that a leak on the suction side of the auxiliary pump would entrain air into the hydraulic fluid, but may not display significant fluid loss. Solution 1: Repair or adjust the steering column (steering shaft) to eliminate the bind.
www.mymowerparts.com Domestic Series 7000 Hydraulics 7.6. 7.11. Disconnect the hydraulic line between the steering unit and the steering cylinder using a 5/8” wrench and a 3/4” wrench. See Figure 7.11. Engine-off test: With the engine turned-off so that no pressure is supplied by the auxiliary pump, the pump within the steering unit should work well enough in manual mode to turn the front wheels from one steering stop to the other (full travel) with roughly 2.75 turns of the steering wheel.
www.mymowerparts.com Domestic Series 7000 Hydraulics 7.15. Have an assistant slowly turn the steering wheel until the steering linkage hits the end of its travel. Applying pressure to the steering wheel while the linkage is at full lock will build pressure in the system. 7.16. Observe the pressure reading on the test kit, at full-lock. The pressure should be in the range of 1,087 to 1,160 PSI (75 to 80 Bars) for the Sauer unit, and 1,450 PSI (100 Bars) for the Ross unit. See Figure 7.16.
www.mymowerparts.com Domestic Series 7000 Hydraulics 8. HYDRAULIC LIFT CYLINDER AND CONTROL VALVE 8.1. If the hydraulic lift cylinder does not work or is low on power, begin by making a visual inspection of the cylinder, linkage, and feedback rod. See Figure 8.1. 8.3. Orientation of the valve: See Figure 8.3.
www.mymowerparts.com Domestic Series 7000 Hydraulics 8.5. Control Linkage Description: • The feedback rod and link assembly governs the motion of the lift arms. It transmits motion from the lift arms back to the pin that provides the fulcrum point that the bottom end of the feedback link pivots on. • A pin on the operator controlled linkage engages the top end of the feedback link. • The valve link is connected to the center point of the feedback link.
www.mymowerparts.com Domestic Series 7000 Hydraulics 8.21. Carefully close the valve on the test kit. Do not close the valve all the way. It is not necessary to move the lift cylinder to generate pressure. See Figure 8.21. 8.16. Install the test kit with the flexible line connected to the pressure gauge end of the kit, and the control valve connected to the flow meter end of the kit. See Figure 8.16. Test kit connection to lift control valve Figure 8.16 Figure 8.21 8.17.
www.mymowerparts.com Domestic Series 7000 Hydraulics 8.26. Set the parking brake, place the gear selector in neutral, open the flow valve on the gauge set all the way, and confirm that no unsafe conditions will be created by starting the tractor engine. 8.30. The pressure should approach but not exceed 1,500 PSI (103 Bars). 8.31.
www.mymowerparts.com Domestic Series 7000 Hydraulics 9.5. 9. TANDEM PUMP 9.1. Attachments are covered in a separate section. This section covers the portions of the hydraulic system that remain permanently attached to the tractor. NOTE: Unless stated otherwise, it is not necessary to remove the fenders to perform the tests described in this section. Some of the figures in this section show the fenders removed. This was done for photographic purposes, not for mechanical purposes. 9.2.
www.mymowerparts.com Domestic Series 7000 Hydraulics 9.10. Observe the flow rate. It should be in the 6.5 GPM (25 L/m) range. See Figure 9.10. 25 L/m flow Flow valve open No pressure • System pressure is regulated by a relief valve in the loader valve. • In this test, we have effectively disabled that relief valve. Use caution not to overload the system by closing the valve farther or longer than necessary to test pump performance. 9.13.
www.mymowerparts.com Domestic Series 7000 Hydraulics 10. 10.5. With the test kit installed as shown, pushing the loader valve forward to the detent will generate a reading on the flow meter of about 6.6 GPM (25 L/m) when the test kit flow valve is open. Pressure will be zero. See Figure 10.5. LOADER VALVE 10.1. the simplest way to check pressure to the attachment is by connecting the test kit to the Quick Disconnect ports. See Figure 10.1.
www.mymowerparts.com Domestic Series 7000 Hydraulics 10.7. While holding the loader valve lever forward, close the flow valve on the test kit. Because there is a pressure relief feature in the loader valve, the pressure should rise to 1,500 PSI (103 Bars) and hold steady. See Figure 10.7. 10.10. It is necessary to unbolt the pivot bracket assembly from the loader valve in order to get a wrench on the relief valve adjustment screw. The pivot bracket can be unbolted using a 3/8” wrench. See Figure 10.10.
www.mymowerparts.com Domestic Series 7000 Hydraulics 11. 10.13. Loosen the jam nut using a 7/8” wrench and turn the adjuster screw using a 7/16” wrench. See Figure 10.13. COMPONENT BREAKDOWN: AUXILIARY PUMP (TANDEM PUMP SIMILAR) NOTE: The auxiliary pump is to be replaced as a unit if it fails. Dissassembling it will VOID the warrantee. The pump has been disassembled here to illustrate how it works. NOTE: Individual pump components will not be available through Cub Cadet. 11.1.
www.mymowerparts.com Domestic Series 7000 Hydraulics 11.2. The back cover can be removed from the pump by removing the four socket head cap screws. See Figure 11.2. 11.7. There is a cartridge that slides into the pump body. See Figure 11.7. Second pump gear Pump with back cover removed Splined shaft Shaft with pump gear Bearing cartridge Figure 11.7 Figure 11.2 11.3.
www.mymowerparts.com Domestic Series 7000 Hydraulics 12. 12.2. With the fittings removed, the three sections of the steering unit can be separated. See Figure 12.2. COMPONENT BREAKDOWN: STEERING UNIT NOTE: The steering unit is to be replaced as a unit if it fails. Dissassembling it will VOID the warrantee. The steering unit has been disassembled here to illustrate how it works. NOTE: Individual components of the steering unit are not available through Cub Cadet. 12.1.
www.mymowerparts.com Domestic Series 7000 Hydraulics 12.6. The spool and sleeve can be easily tapped-out of the housing. A thrust bearing assembly fits between the spool and sleeve assembly and the housing. See Figure 12.6. 12.4. The cardan shaft transfers motion from the steering wheel, through the body of the steering unit, to the pump. See Figure 12.4. Figure 12.4 Figure 12.6 12.5. The relief valve ball and retaianer live in one of the fittinig bores.
www.mymowerparts.com Domestic Series 7000 Hydraulics 12.10. There are two types of leaf spring: flat and bowed. A pair of each goes together, back-toback. See Figure 12.10. 12.8. A dowell pin connects the spool and sleeve axially, and transmits steering force to the sleeve from the cardan shaft. See Figure 12.8. Figure 12.10 Figure 12.8 12.9. Removing the dowel pin allows the spool to separate from the sleeve. See Figure 12.9. Figure 12.
www.mymowerparts.com Domestic Series 7000 MFD Domestic Series 7000 MFD ABOUT THIS SECTION: 1. TO IDENTIFY THEM MFD: Early (2002 and 2003) production of the domestic Series 7000 four wheel drive tractors used an MFD (Mechanical Front Drive) sourced from another manufacturer. Beginning with serial number 1B014G20001 (February 1st, 2004) domestic Series 7000 tractors were built using an MFD assembled in Cub Cadet’s transmission plant in Leitchfield, KY.
www.mymowerparts.com Domestic Series 7000 MFD 1.4. The MFD manufactured by Cub Cadet is mounted to two one-piece brackets. See Figure 1.4. 1.7. To visually distinguish the Series 5000 MFD from the Series 7000 MFD: the Series 5000 unit has four tapped holes or wheel studs on the axle flanges, while the Series 7000 has five tapped bolt holes on the axle flanges. 1.8. The Series 5000 MFD is wider than the Series 7000 MFD.
www.mymowerparts.com Domestic Series 7000 MFD 2. 1.10. The difference in widths is accounted for by the fact that axle flanges protrude visibly further out of the housing on the 618-0428 (5000 MFD) than they do on the 618-0484 (7000 MFD). NOTE: This procedure can be done on tractors that are equipped with cutting decks, front-end loaders, and other attachments. It is not necessary to remove the attachments in order to remove and replace the MFD. 1.11.
www.mymowerparts.com Domestic Series 7000 MFD 3.5. 3. REMOVAL 3.1. Loosen the set screw that secures the back end of the 4 W.D. drive shaft to the splined output shaft on the front of the transmission. See Figure 3.1. 4 W.D.

www.mymowerparts.com Domestic Compact Electrical Systems Domestic Compact Electrical Systems About this section: 1.8. This part of the manual provides verbal descriptions of the function of each electrical component in the system. It is best used to compliment the Cub Cadet Wiring Schematics found on disc 772-9085A-CD, available through Cub Cadet. Gasoline engines will have a magneto ground and after-boom solenoid power-off to turn-off the engine. 1.9.
www.mymowerparts.com Domestic Compact Electrical Systems 1.14. As with all electrical systems, do not neglect the basics: clean connections and good ground paths. See Figure 1.14. 1.11. The gasoline engines use flywheel mounted rotors and engine mounted stators to generate A.C. current. The current is processed through regulator-rectifier modules before being passed to the main harness of the tractor. See Figure 1.11. Regulator / rectifier Mag.
www.mymowerparts.com Domestic Compact Electrical Systems 2.2. Behind the access panel is a fuse center. See Figure 2.2. 2.4. Diesel powered tractors will have the following components at the right rear corner of the engine bay: • A single relay to power the glow-plug circuit. (P/N: 725-04164) • A glow-plug timer that supplies power to the windings of the glow plug relay during the prestart cycle. Caterpillar and Briggs & Stratton Daihatsu each use different glow-plug timers.
www.mymowerparts.com Domestic Compact Electrical Systems 2.6. 2.7. Kohler powered tractors use a similar engine kill relay arrangement. See Figure 2.6. Kill relay Located on the dash panel are the hazard flasher switch, light switch, PTO switch, Key switch, and instrument panel. See Figure 2.7. Lights Hazard PTO Charge relay Kohler-powered tractor Main fuse Key switch Figure 2.6 Figure 2.7 • Engine kill relay has red, green, and black wires.
