Traction Reverse The traction circuit operates essentially the same in re- verse as it does in forward. However, there are a few dif- ferences in operation. When the traction pedal is pressed to the reverse posi- tion, the linkage from the pedal positions the swash plate in the traction pump so oil flows out of port A.

Page 115 6. Inspect manifold (22) for cracks, surface scoring, peening, chipping. Replace manifold if any of these conditions exist. A polished pattern on the ground sur- face from commutator or rotor rotation is normal. NOTE: The rotor set consists of the rotor (19), vanes (20), and stator (21).
Page 116: Assembly
14. If the housing (3) has passed inspection to this point, inspect outer bearing (2), inner bearing (10), thrust washers (8), and thrust bearing (9). Bearing roll- ers must be firmly retained in the bearing cages but must rotate and orbit freely. All rollers and thrust washers must be free of peening and corrosion.
Page 117 6. Apply masking tape around splines or keyway on coupling shaft (11) to prevent damage to seal. IMPORTANT: The outer bearing (2) is not lubricated by the system’s hydraulic fluid. Make sure it is thor- oughly packed with Mobil Mobilith SHC R 460 grease.
Page 118 NOTE: The rotor set consists of the rotor (19), vanes (20), and stator (21). Rotor set components may be- come disassembled during service procedures. Do not service separately.

Multimeter The meter can test electrical components and circuits for current, resistance, or voltage. NOTE: Toro recommends the use of a DIGITAL Volt– Ohm–Amp multimeter when testing electrical circuits. The high impedance (internal resistance) of a digital me- ter in the voltage mode will make sure that excess cur- rent is not allowed through the meter.
Page 133: Troubleshooting
Troubleshooting For effective troubleshooting and repairs, you must have a good understanding of the electrical circuits and CAUTION components used on this machine (see Wiring Sche- matics section of this chapter). Remove all jewelry, especially rings and If the machine has any interlock switches by–passed, watches, before doing any electrical trouble- shooting or testing.
Page 134: General Run & Transport Problems
Starting Problems (continued) Problem Possible Causes Engine cranks, but does not start. Wiring to start circuitry (see Wiring Schematics) is loose, corroded, or damaged. 10 ampere fuse is missing or open (SP 5020). Ignition switch is faulty. Fuel solenoid is faulty. Spark plugs are faulty.
