Section Drawing and Integral Valves
NOTE: The steering control valve housing (7) Fig. 2 has internally two anti-cavitation valves (EE) and one check valve (CC). Before removing these valves, verify their positions.
17. To disassemble these valves, insert soda straws (3) in each end of the threaded holes, refer to Figure 3. Remove the steering control valve housing from the vise and tilt it until the port face (4) is upward. Continue turning until the roll pins (2) and ball checks (1) slide through the straws (3).

Inspection
1. Clean all parts in cleaning solvent and air dry on paper towels. Do not use cloths to wipe parts dry, as it may leave lint on the parts.
2. Check all machined surfaces for wear or damage. If there are rough places on the ends of the gerotor star or gerotor (4), steering control valve housing (7), end cap (2), or spacer plate (5), use 600 grit emery cloth to smooth the surfaces, refer to Figure 2. Place the emery cloth on a flat surface. If the emery cloth is new, rub a piece of steel across the emery cloth six times to remove the sharp pieces of grit. Make sure that the part is held flat on the emery cloth. Rub each part across the cloth six times. Check to see if the rough places are removed. Use this method until all rough places are removed. Clean the parts in cleaning solvent to remove any grit.
3. If the spool (9) and sleeve (8) or the bore in the housing of the steering control valve (7) is damaged or worn, use a new steering control valve.
4. Inspect the cap screws (1), pin (11), backup washer (15), seal ring (16), O-ring (17), needle thrust bearing (13) and bearing race (14). Use new parts as required.
5. If your steering control valve has anti-cavitation and check valves, inspect the balls checks (20), (23) and roll pins(21), (22) for damage or wear. Use new parts as required.

OPERATION
The refrigerant circuit of the air conditioning system contains five major components: compressor, condenser, receiver-drier, expansion valve and evaporator. These components are connected by tubes and hoses and operate as a closed system.
The air conditioner system is charged with HFC-134a refrigerant.
The compressor receives the refrigerant as a low pressure gas. The compressor then compresses the refrigerant and sends it in the form of a high pressure gas to the condenser. The air flow through the condenser then removes the heat f rom the refrigerant. As the heat is removed the refrigerant changes to a high pressure liquid.
The high pressure refrigerant liquid then flows from the condenser to the receiver-drier. The receiver-drier is a container filled with moisture removing material, which removes any moisture that may have entered the air conditioner system in order to prevent corrosion of the internal components of the air conditioner system.
The refrigerant, still in a high pressure liquid form, then flows from the receiver-drier to the expansion valve. The expansion valve then causes a restriction in flow of refrigerant to the evaporator core. The evaporator meters refrigerant flow based on evaporator heat load.
As the refrigerant flows through the evaporator core, the refrigerant is heated by the air around and flowing through the evaporator fins. The combination of increased heat and decreased pressure causes the air flow through the evaporator fins to become very cool and the liquid refrigerant to become a low pressure gas. The cooled air then passes from the evaporator to the cab for the operator’s comfort.
The electrical circuit of the air conditioning system consists of a fan speed control, temperature control, one (1) relay, a blower motor, blower resistor, A.C. compressor clutch, A.C. low pressure switch, A.C. high pressure switch, and A.C. warning light.

TROUBLESHOOTING
Perform a visual inspection of the machine. Check the following and correct as necessary:
1. – Obtain service history if possible.
2. – Is compressor drive belt in place and tensioned?
3. – Are grille screens, fan blades, condenser, air filter, and evaporator unobstructed?
4. – Are there any sharp bends or kinks in the hoses?
5. – Are there heavy accumulations of oil, or oily dust around the fittings, indicating refrigerant
leakage?
6. – Are air ducts undamaged, sealed properly and in position?
7. – Condensate drain hoses and check valves present and unobstructed?
Problem: No Cooling

Transmission Clutch Calibration
The Transmission ECM has the capability to find the optimal adjustment of the clutch filling parameters for each individual transmission, providing the ability to individually adjust the optimum fill time for the individual transmission in the machine. Clutch Filling Parameter Calibration is performed on each machine at the plant and should be repeated at the first 250 hours of use and every 1000 hours thereafter.
Before doing the following transmission clutch calibration procedures make sure of the following:
1. The machine is running and the transmission oil is warm.
2. Engine low idle speed is correct.
3. The transmission is in neutral.
4. The park brake is applied.
5. If steps 1 through 4 have been accomplished, calibrate the transmission clutches as follows:
A. Press and hold the enter key for 2 to 3 seconds and the monitor will change to SELECT.
B. Use the down arrow and high light “CONFIG”, press the enter key.
C. Press the down arrow and high light “CALIB G/B”, press the enter key.
D. Monitor will state “CALIB G/B” “CONFIRM PLEASE”, press the enter key.
E. If the conditions are not correct for clutch calibration the monitor will display the problem that needs to be corrected.
F. Clutch calibration status will be displayed on the monitor, “ADJUST K1, K2, K3, K4, KV, KR”.
G.After completing the Clutch Calibration procedure, turn the machine OFF for 15 seconds. This sets the calibration in the controller.
Gear Selections
The transmission provides 4 forward and 3 reverse gear selections. The transmission ratios were designed to give optimized speed and torque for each gear selection. The torque converter is a single stage torque converter (one locking unit in the torque converter).
Automatic/Manual Modes
The automatic/manual switch is located on the right control panel. The transmission is in automatic mode when the top of the automatic/manual switch is depressed. The Transmission Display Center indicates when the machine is in the automatic mode.
Upshifting in Automatic Mode
Upshifting is determined by machine speed and the torque on the transmission.
The transmission will shift from first or second gear up to the highest gear selected as the accelerator is depressed, machine speed increases, and required torque is reduced.
If the machine speed is increasing, but the operator
is not depressing the accelerator (such as when going down a hill), the transmission will not upshift.
As the operator depresses the accelerator and the torque on the transmission is lowered, the transmission will upshift.
Downshifting in Automatic Mode
Downshifting is determined directly by machine speed and transmission torque. The transmission will downshift to first or second gear as machine speed decreases and transmission torque increases. For example, if the unit begins to climb a hill in forth gear and the machine speed decreases, as the torque requirement increases, the transmission will downshift into third, then second, and down to first gear, if necessary.
Upshifting in Manual Mode
In the manual mode, the transmission starts out in the selected gear and stays in that gear until the operator selects another gear or direction. The transmission can be upshifted without reducing engine speed or machine speed.
If the gear selected is two or more gears higher than the present gear, the transmission will shift up through the gears at 2.5 second intervals until the selected gear has been reached.
