Check Points and Transmission Auxiliary System

43- Circle guides Check and adjust

The circle and circle guides must be kept clean to prevent caking. If the circle guides are excessively loose, the gear teeth will wear, causing the circle turn to function erratically.

WEAR PLATE ADJUSTMENT

Proceed as follows:

The first adjustment is to eliminate play between the upper wear plates and the upper circle guides (vertical clearance).

To make this adjustment, shims between wear plates and the upper circle surface must be removed.

NOTE: Do not throw-away the shims that were removed. They can be used again in other new adjustment.

Make sure that the maximum clearance does not exceed 1.52 mm (0.6 in). This adjustment must be completed on each of the four (4) guides, one at a time, beginning with one closest to the circle turn motor pinion gear.

After vertical adjustment rotate the circle 3600 to be sure that the circle turns freely.

Next, adjust the clearance between the wear plates and the inner circle guides (radial clearance), proceeding as follows: Circle turn clearances With the vertical clearance already adjusted, loosen the circle guide nuts and the jam nuts of radial clearance adjusting screws. Position the circle turn motor pinion in such a way that the tooth engagement is as shown below. Make sure that the center of the circle turn motor pinion, center line of the engaged tooth and the front guide center locknut are aligned.

Put one flank of the pinion tooth in contact with one circle tooth. Turn adjusting screws of front guide as necessary to provide 0.76 mm (0.3 in) between the opposite flanks of the circle and pinion tooth.

After adjustment of the front guide radial play, tighten lock nuts and perform rear guides radial adjustment to a maximum clearance 0.76 mm (0.3 in) between the inner circle guides and the curved circle guide wear plates using the adjusting screws. Tighten the adjusting screw jam nuts and circle guide lock nuts. Rotate the circle 3600. to be sure it turns freely. Should the circle not turn freely, perform the adjustment again, increasing clearance between tooth flanks. Do not exceed the upper limit.

44- Drawbar ball nut torque Check

Check drawbar ball nut. Torque should be 75 to 91 kgm (540 to 660 ft. lbs.). 46- CHECK POINTS AND TRANSMISSION AUXILIARY SYSTEM Check

45- Batteries Replace Operator's console 1,2,3,4- COME-HOME SWITCH

This switch is located in the lower part of the right console and is used to move the machine in the event of a transmission electronic control unit problem. The switch has three positions: Forward, Neutral and Reverse. The switch must be in the Neutral position with parking brake "on" to start the machine.

The batteries are "Maintenance Free" type and electrolyte level check is not required. Do not leave lamps switched on for long intervals of time with the engine stopped or idling. Keep batteries clean, specially on its top surface.

Make sure of that cable terminals are correctly connected to the batteries poles. Always disconnect master switch before serviceing batteries. To use the system, stop the engine, apply the parking brake and set the switch on Neutral position.
