MOTOR GP-HYD 10R5466 - Caterpillar

Tracks
Adjust
The sag in the track is measured between the sprocket and carrier roller (1) and between the carrier roller and front idler (2). Correct adjustment for XL machines gives a dimension (3) of 25 6 mm (1.0 .25 in). Correct adjustment for low ground pressure (LGP) machines gives a dimension (3) of 35 6 mm (1.3 .25 in). If the track is too loose:
Do not attempt to tighten track when dimension (3) is 100 mm (3.9 in) or more. Contact your Caterpillar dealer for track service or instructions.
1. Remove the adjusting valve cover plate. 2. Add grease (MPGM) through adjusting valve (4) until dimension (3) is correct.3. Operate the machine back and forth to equalize the pressure. Allow the machine to coast to a stop. Do not use the brakes.4. Remeasure dimension (3). If track is too tight:1. Loosen relief valve (5) one turn only and allow grease to escape.2. Close the relief valve.3. Add grease (MPGM) through adjusting valve (4) until dimension (3) is correct.4. Install the valve cover plate.5. Repeat procedure on the other track.Track Shoe Bolt Torque
The torque requirement for track shoe bolts is 170 40 N m (120 30 lb ft) plus an extra 1/3 turn (120 degrees). For split master link bolts, torque to 170 40 N m (120 30 lb ft) plus an extra 1/2 turn (180 degrees).Fan Drive Bearing
Open the engine access cover (if equipped) on the left side of the machine. Lubricate one fitting.Air Conditioner (If Equipped)
Test Operation - Adjust Belt
1. Start the engine. Operate the engine at HIGH IDLE. 2. Set the air conditioner control for MAXIMUM cooling, and fan control on MEDIUM.3. Allow two minutes for the air conditioning system to stabilize. 4. Check for refrigerant in the system as follows: Feel suction line (1) and discharge line (2).If the system contains refrigerant, the discharge line is warmer than the suction line.Poor cooling results if the system does not contain, or is very low on refrigerant.5. Stop the engine to inspect the compressor belt. 6. Inspect the condition and the adjustment of the compressor belt. The belt
