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.
1. EXPANSION VALVE 2. EVAPORATOR 3. COMPRESSOR 4. CONDENSER 5. RECEIVER-DRIER
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.

Adjust Backlash and Bearing
Preload
STEP 175
Place a dial indicator right-angled at the outer diameter of the tooth flank (ring gear).
Adjust the pinion to ring gear backlash to the low side of specifications (see value etched on the outer diameter of the ring gear) by alternately turning each of the adjusting nuts to move the ring gear closer to or further away from the pinion. Backlash is checked using a dial indicator against a tooth on the ring gear.
NOTE: Rotate the differential several times and recheck the backlash.
STEP 176
Go to the adjusting nut opposite the ring gear and loosen the nut approximately one turn to release pressure on the bearing. It should be very noticeable that pressure is released on the bearing, as the adjusting nut will turn much easier.
STEP 177
Tighten the adjusting nut slowly until firm contact is made with the bearing.
NOTE: As the adjusting nut makes firm contact with the bearing, the adjusting nut will immediately begin
to turn much harder.
STEP 178
To adjust the bearing preload, note the position of the adjusting nut. Now tighten the nut two additional
notches.
STEP 179
As the bearing preload is adjusted as described in steps 176, 177 and 178, pinion to ring gear backlash may increase slightly. Check pinion backlash to confirm that it is within specifications. If backlash is
outside of specified range, repeat step 175 through 179 again.
STEP 180
A8
Coat several teeth on the ring gear with marking ink and roll the ring gear in both directions over the drive pinion.
Compare the obtained tooth contact pattern with the examples on page 4 and 5.
ATTENTION: If the tooth contact pattern differs, there has been a measuring error at determination of the shim. This must be corrected.
STEP 181
Install both adjusting nuts with the slotted pins on the differential carrier.
STEP 182
BD01F099
Install the CAS2846 pinon lifting bail onto the pinion shaft and insert the differential carrier into the axle casing.
