STANDARD HYDRAULIC SYSTEMS ON THE DOMESTIC SERIES 5000: ORIENTATION NOTE: Subsections 1 and 2 of the Domestic Series 5000 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 filter (P/N: BS-492932S) is located on the return manifold, atop the transmission.
www.mymowerparts.com Domestic Series 5000 Hydraulics 1.6. The steering and lift cylinder are also powered by the a Sauer-Danfoss SNP 1/2.6 S auxiliary pump. 1.10. The control valve directs fluid pressure to a single-acting hydraulic cylinder that lifts the threepoint lift arms. 1.7. The steering unit, 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. 1.11.
www.mymowerparts.com Domestic Series 5000 Hydraulics 1.22. From the E port, fluid will travel to the lift control valve. See Figure 1.22. 1.17. The process is reversed for right turns. See Figure 1.17. Pressure from L port (left turn) Pressure from R port (right turn) Pressure from E port Steering cylinder Figure 1.17 Figure 1.22 1.18. From the steering system, the fluid may follow one of two return paths: 1.23.
www.mymowerparts.com Domestic Series 5000 Hydraulics 1.26. When the tractor operator moves the control lever forward to lower the three point hitch, the lift control valve allows fluid to escape from the lift cylinder as the cylinder retracts under the weight of any accessories supported by the hitch. 1.27. Increased fluid volume beyond normal return flow rate is generated when the lift arms are lowered.
www.mymowerparts.com Domestic Series 5000 Hydraulics 2.5. : 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. Tilting the swash plate the other way causes the variable displacement pump to drive fluid through the fixed displacement pump in the opposite direction. See Figure 2.6.
www.mymowerparts.com Domestic Series 5000 Hydraulics 3.4. 3. EXTERNAL CHECKS 3.1. If the transmission creeps, check the neutral control adjustment. See Figure 3.1. Neutral return bracket Confirm that full travel is achieved in the reverse direction. See Figure 3.4. Pedal linkage: Reverse Move shoulder bolt in slot to establish neutral Hydro linkage: Reverse Note: gap Brake linkage Figure 3.4 Figure 3.1 3.5.
www.mymowerparts.com Domestic Series 5000 Hydraulics 3.6. If the tractor fails to achieve normal ground speed, and the hydro pump emits an unusual amount of noise, check for brake drag: • Confirm that the neutral return and hydro control linkages are correctly adjusted. • With the tractor on a smooth, firm, level surface, place the gear selector in neutral, release the parking brake, and attempt to push the tractor.
www.mymowerparts.com Domestic Series 5000 Hydraulics 4. 5. 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.
www.mymowerparts.com Domestic Series 5000 Hydraulics 5.8. The charge pressure should read at least 30 PSI (2.07 Bars) @ 1,200 RPM. See Figure 5.8. 200 PSI gauge 5.11. If the charge pressure is good, but drive has been lost in one direction only, the corresponding charge check valve may not be working. High pressure gauge • There is a charge check valve located in each circuit: one for forward, one for reverse.
www.mymowerparts.com Domestic Series 5000 Hydraulics 5.16. With the engine at a minimum speed of 1,200 RPM, fluid flow of roughly 2 GPM (7.60 LPM) should register on the meter. See Figure 5.16. 5.13. When removed, each charge relief valve comes out as a cartridge. The light compression spring provides the check valve function. The heavy compression spring provides system relief. System relief comes into play in the event of a drive system overload. See Figure 5.13.
www.mymowerparts.com Domestic Series 5000 Hydraulics other (T port). If there is pressure to the steering unit, at least one return path will have pressure. 5.21. If any mechanical problem is found with the check valve, it is to be replaced as a unit. Individual service components are not available through Cub Cadet. See Figure 5.21. 5.19. The return circuit check valve maintains a minimum pressure given sufficient flow.
www.mymowerparts.com Domestic Series 5000 Hydraulics 6.5. 6. AUXILIARY PUMP 6.1. The auxiliary pump provides pressure for the hydrostatic power steering unit, the lift cylinder attached to the three-point hitch, and any hydraulic-driven accessories that may be installed on the tractor. 6.2. Series 5000 tractors come with a single auxiliary pump mounted to the right side of the transmission. See Figure 6.2. The filter and suction tubes are easily reached for inspection with little or no disassembly.
www.mymowerparts.com Domestic Series 5000 Hydraulics 6.10. 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. 6.13. Close the flow valve until the pressure gauge reads 1,500 PSI (103 Bar). Note the flow reading. See Figure 6.13. 6.11. Start the engine, allow the engine and hydraulic system to warm-up. See Figure 6.11.
www.mymowerparts.com Domestic Series 5000 Hydraulics 7. STEERING PUMP AND CYLINDER 7.5. The following set of symptoms, causes, and solutions has been adapted from a list compiled by Sauer-Danfoss to aid in the diagnosis of hydrostatic steering issues. Internal steering unit problems are described to aid technicians in distinguishing internal steering unit problems from problems that lie elsewhere in the system. Internal problems dictate replacement of the steering unit.
www.mymowerparts.com Domestic Series 5000 Hydraulics • • Backlash Slow Steering: Cause 1: Wear or play between the steering column and the cardan shaft. Cause 1: Insufficient fluid flow to the steering unit. Confirm by testing the out-put of the auxiliary pump. Solution 1: If the wear is in the steering column, replace the steering column (steering shaft per Cub Cadet IPL). If the wear is in the cardan shaft, this is an internal problem.
www.mymowerparts.com Domestic Series 5000 Hydraulics • 7.10. Install the hydraulic test kit in either one of the two hydraulic lines leading from the steering pump to the steering cylinder. Steering Power Too Low: Cause 1: The relief valve is set too low or malfunctioning. 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. Solution 1: Internal problem; relief valve.
www.mymowerparts.com Domestic Series 5000 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. 7.20. To check for blow-by, turn the steering wheel in whichever direction causes the flow meter on the test kit to rise: NOTE: The wheel can be turned in either direction to get a pressure reading.
www.mymowerparts.com Domestic Series 5000 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 valve, cylinder, linkage, and hydraulic hose. See Figure 8.1. Pressure line from E port Direct return to transmission Line to cylinder 8.4. If the lift cylinder is operable, run it through the full range of travel to confirm that the feedback rod is working correctly.
www.mymowerparts.com Domestic Series 5000 Hydraulics 8.6. Fluid movement: • Fluid is constantly circulating from the auxiliary pump, to the steering unit, through the valve, then to the return manifold. • • 8.7. 8.10. Confirm that the lift cylinder control valve is getting pressure from the steering pump: When the valve is actuated to raise the lift arms, it redirects fluid from this path to the lift cylinder.
www.mymowerparts.com Domestic Series 5000 Hydraulics 8.16. The flow should remain constant, while the pressure climbs to 1,500 PSI (103 Bars). Open the valve a soon as the readings are confirmed. 8.13. The flow meter should rise to 4 GPM (15 LPM) and hold steady at that level. See Figure 8.13. NOTE: Remember, the flow varies with engine RPM, but does not vary with pressure generated unless the auxiliary pump is failing. 8.17. Turn off the engine.
www.mymowerparts.com Domestic Series 5000 Hydraulics 8.22. Disconnect the flexible hydraulic line that leads from the control valve to the lift cylinder using an 11/16” and a 3/4” wrench. See Figure 8.22. 8.27. As the lift arms travel upward, note the reading on the flow meter. It should be in the vicinity of 5 GPM (19 LPM). See Figure 8.27. Disconnect here UP 4 GPM No significant pressure Figure 8.27 Figure 8.22 8.23. Connect the test kit to the 3/8” flare fittings.
www.mymowerparts.com Domestic Series 5000 Hydraulics 8.30. If the pressure delivered to the control valve is sufficient, but the pressure delivered to the cylinder is low, then the problem is likely to be in the control valve. 8.31. If the pressure delivered to the cylinder is sufficient, yet the cylinder does not perform adequately, look for leakage from the cylinder. 9.2.
www.mymowerparts.com Domestic Series 5000 Hydraulics 9.7. Reducing throttle to the 1,200-1,500 RPM range, observe the flow while pushing the loader valve lever forward to the detent. The flow should be around 5.0 GPM (19.0 LPM). 9.11. If the pressure varies slightly in above or below 1,500 PSI (103 Bars), the relief valve can be adjusted. It is located on the top, outboard corner of the loader valve. 9.8.
www.mymowerparts.com Domestic Series 5000 Hydraulics 9.18. Once access is gained to the adjustment screw, index the screw, jam nut, and housing using a marker. 9.16. Unbolting the loader valve bracket from the frame of the tractor will provide additional wrench clearance between the pivot bracket and the fender. This can be done with a 1/2” wrench. See Figure 9.16. 9.19. Loosen the jam nut using a 7/8” wrench and turn the adjuster screw using a 7/16” wrench. See Figure 9.19.
www.mymowerparts.com Domestic Series 5000 Hydraulics 10. COMPONENT BREAKDOWN: AUXILIARY PUMP 10.2. The back cover can be removed from the pump by removing the four socket head cap screws. See Figure 10.2. NOTE: The auxiliary pump is to be replaced as a unit if it fails. Disassembling it will VOID the warranty. The pump has been disassembled here to illustrate how it works. Pump with back cover removed Splined shaft NOTE: Individual pump components will not be available through Cub Cadet. 10.1.
www.mymowerparts.com Domestic Series 5000 Hydraulics 11. 10.7. There is a cartridge that slides into the pump body. See Figure 10.7. COMPONENT BREAKDOWN: STEERING UNIT NOTE: The steering unit is to be replaced as a unit if it fails. Disassembling it will VOID the warranty. The steering unit has been disassembled here to illustrate how it works. Second pump gear Shaft with pump gear NOTE: Individual components of the steering unit are not available through Cub Cadet. 11.1.
www.mymowerparts.com Domestic Series 5000 Hydraulics 11.4. The cardan shaft transfers motion from the steering wheel, through the body of the steering unit, to the pump. See Figure 11.4. 11.2. With the fittings removed, the three sections of the steering unit can be separated. See Figure 11.2. Figure 11.2 Figure 11.4 11.5. The relief valve ball and retainer live in one of the fitting bores. Carefully extract them with a magnet while the steering unit is in the upright position. See Figure 11.5. 11.3.
www.mymowerparts.com Domestic Series 5000 Hydraulics 11.8. A dowel pin connects the spool and sleeve axially, and transmits steering force to the sleeve from the cardan shaft. See Figure 11.8. 11.6. 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 11.6. Figure 11.8 Figure 11.6 11.9. Removing the dowel pin allows the spool to separate from the sleeve. See Figure 11.9. 11.7.
www.mymowerparts.com Domestic Series 5000 Hydraulics 11.10. There are two types of leaf spring: flat and bowed. A pair of each goes together, back-toback. See Figure 11.10. Figure 11.

www.mymowerparts.com Domestic Series 5000 MFD Domestic Series 5000 MFD ABOUT THIS SECTION: 1. TO IDENTIFY THEM MFD: The Cub Cadet Series 5000 MFD (Mechanical Front Drive) axle is visually similar to the MFDs used in the Series 7000 Tractor. The MFDs used in the Series 5000 are functionally different from those used in the Domestic Series 7000, and cannot be inter-changed. The first part of this section describes the characteristics that will enable a technician to identify the three different units. 1.
www.mymowerparts.com Domestic Series 5000 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 5000 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 5000 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. Remove the four bolts holding the steering cylinder bracket to the MFD housing using a 19 mm wrench. See Figure 3.5. Lock washers Steering cylinder mounting bracket S Figure 3.5 Figure 3.1 NOTE: Only the inner two bolts (closer to the axle mounting bracket) have lock washers. 3.2.
www.mymowerparts.com Domestic Series 5000 MFD 3.8. 3.12. Remove the four nuts that secure the front axle bracket to the frame using a pair of 3/4” wrenches. See Figure 3.12.

www.mymowerparts.com Domestic Series 5000 MFD 6. IN FRAME REPAIRS: DROP AXLE COVER 6.1. If there is an obvious problem within the drop axle housing, or for purposes of inspection, the axle cover is easily removed. 6.2. Remove the axle cover bolts using a 13 mm wrench. See Figure 6.2. 6.5. The inner axle bearing is a slip fit on the axle. It can be removed with light pressure on the bearing, or (preferably) by lifting the axle bevel gear. See Figure 6.5.
www.mymowerparts.com Domestic Series 5000 MFD 6.8. After the axle is separated from the bearing and cover, the bearing, and the seal that protects it may be easily removed from the cover. See Figure 6.8. Outer axle bearing: slip fit in bore, stops against shoulder • Use a seal driver to install a new seal in the cover. There is no shoulder for the seal to seat against, so it must be driven far enough that the outer edge of the seal is flush with the outer edge of the machined bore that the seal seats in.
www.mymowerparts.com Domestic Series 5000 MFD 7. IN-FRAME REPAIRS: DROP-AXLE REMOVAL 7.1. The drop axle assembly can also be removed complete. 7.2. If working on the left side drop axle, disconnect the cylinder mounting stud from the steering arm using a 24 mm wrench to hold the bottom nut and a 1 1/16” wrench to turn the top nut. 7.3. 7.5. Sealed bearing Washer Stub shaft Steering arm Remove the nut from the tie rod end, using a 19 mm wrench for the nut and a 17 mm wrench to hold the stud.
