Form No. 3382-509 Rev A Wheel Motor Kit Reelmaster® 5410/5510/5610 and Groundsmaster® 4300-D Traction Unit Model No. 125-8785 Installation Instructions WARNING CALIFORNIA Proposition 65 Warning This product contains a chemical or chemicals known to the State of California to cause cancer, birth defects, or reproductive harm. Important: The Wheel Motor Kit Installation Instructions cover the removal and installation of new wheel motors, wheel motor components and hydraulic filters.

Inspecting the Wheel Motors Special Tools Required 1. Park the machine on a level surface, engage the parking brake, lower the cutting units and stop the engine. Remove the key from the ignition switch. Note: The following special tools (or equivalent) will be required to diagnose and repair affected units: 2. Refer to Toro Service Bulletins LR08–35 and R08–41 for the list of machines with affected motors.

Remove the smaller charge hydraulic filter head assembly and install a 500 psi pressure gauge in-line with the charge supply tube as shown in Figure 5. If the pressure gauge is part of a flow meter assembly, ensure the flow meter is unrestricted before performing the following tests.

With the flow meter unrestricted there should be very little load on the hydrostat. Record the gallons per minute being pumped from the hydrostat, record the pressure on the traction loop flow meter and record the charge pressure. Perform the following tests and record the results in the blank fields on this form.
PAGE 6
The hydrostat output is ________ GPM at 1000 psi and charge pressure is ______ psi. 3. With the wheels of the machine off the ground, start the engine and increase the engine RPM to full throttle. 9. Continue to restrict the flow meter in the traction loop until the gauge on the flow meter reads 2000 psi. Record the output of the hydrostat and charge pressure. 4. Slowly depress the traction pedal until fully depressed. Slowly close the flow meter until the pressure gauge reads 1000 psi.

9. Support each wheel motor to prevent them from falling. 5. Thoroughly clean the hydraulic line ends and fittings on the wheel motor to prevent contaminating the hydraulic system. 10. Remove the (4) locknuts securing the brake adapter, wheel motor and spring clip to the frame. 6. Label the hydraulic connections at the wheel motor for assembly purposes. 11. Remove the brake adapter, wheel motor and brake spring bracket from the machine. 7.
PAGE 8
Installing the New Components 10. Install the brake drum, front wheel and extension spring to the machine. Torque the lug nuts to 95 to 122 N-m (70 to 90 ft-lb). 11. Repeat the procedure on the opposite wheel motor. 1. Lubricate and install the new O-rings onto the fittings previously removed from the wheel motors. Updating the Components 2. Install the fittings into the wheel motor ports, orientating them as noted in the removal process. (as required) • Rebuild the Hydrostat.

3. Recheck the hydraulic system oil level and replenish as needed. 4. Install the wheels. 5. Remove the jack stands and test drive the machine to check performance. Submitting Information Via PER case, submit the following items • Model and serial number • Legible, clear photos of the previously removed wheel motor serial tags • All hydraulic pressure and flow measurements logged in steps 7 through 13 in Testing the Machine.
