(28)Track
NOTE: Tracks should be adjusted under the same conditions in which the machine will be used. If packing conditions prevail on the job, the tracks should be adjusted with packing present.
Run the tractor forward at least twice the length of the tractor, then allow tractor to coast to a stop. Do not brake tractor to stop it.
Hydraulic Adjustment
| NOTICE |
|---|
Do not attempt to tighten track when stop on adjusting rod is within .25 inch (6 mm), (A) of stop on roller frame. Contact your AVSpare dealer for track service. |
- 1. Raise inspection plate and add multipurpose-type grease through fill valve until idler moves forward and track is tight.
- 2. Make a mark on the roller frame 1/2 inch (1 cm) behind the idler bearing support.
- 3. Be sure there is space for front idler to retract. Raise inspection plate.
|
Never visually inspect relief valve or fill valve to see if grease is escaping. Always observe the track to see if it has loosened. Open relief valve one turn only. |
|
- 4. Open relief valve and allow the idler to move back. Moving the machine in reverse will help move the idler back.
- 5. Close relief valve.
- 6. Add MPG through fill valve until mark on roller frame is aligned with rear edge of idler bearing support.
NOTE: See your AVSpare dealer if proper adjustment cannot be obtained.
Mechanical Adjustment
NOTE: Track adjustment, with screw-type adjusters, differs from the hydraulic type only in the adjustment mechanism itself.
The track must be adjusted 1/2 inch (1 cm) from fully tight position for proper adjustment.
- 1. Remove guard. Loosen rod clamp nuts.
| NOTICE |
|---|
Do not tighten track when dimension (A) is or will be more than 14.375 inches (365 mm). Damage to screw could result. |
- 2. Turn adjusting nut clockwise to tighten tracks, counterclockwise to loosen to obtain correct adjustment.
- 3. Drive tractor back and forth. Recheck adjustment and dimension (A). Tighten clamp nuts and install guards.
NOTE: See your AVSpare dealer if proper adjustment cannot be obtained.
(29)Air Conditioner
- 1. Start and run engine at high idle. Set air conditioner controls for maximum cold with blower on HIGH. Allow 2 minutes for system to stabilize.
- 2. Observe sight glass. If bubbles are present, turn air conditioner OFF.
- 3. If no bubbles are present in sight glass, feel suction line (A) and discharge line (B). The discharge line should be warmer than the suction line.
- 4. If poor cooling is experienced, turn the air conditioner OFF.
- 5. Stop engine.
- 6. Have your AVSpare dealer service the air conditioner system if necessary.
