Dr:Torque control stroke (A): Without torque control spring capsule 1. Adjustment procedures (1)Procedure is the same as that for the RFD (former type), except that the positive torque control stroke must be determined at the full lever setting. 2. Procedures for adjustment (1)Remove the torque control spring capsule. (2)Operate the pump at approximately N1. (End of idling spring operation < N1.) (3)Tilt the lever to the full side. (4)Set so that R = RF. (5)Increase the speed by pushing in the screw (attached to the bracket on the rear of the tension lever) through the adjusting window. (6)Adjust so that the torque control stroke Dr1 can be obtained. (7)Align N2 and N3 with the torque control spring capsule. 3. Final confirmation (1)After final confirmation, temporarily set the load lever to N = N1, R = idling position. (2)From this condition, increase speed to N = N4. (3)Confirm that positive torque control stroke is Dr2.

Information:

Altitude Operation
The fuel system settings and altitude limits are stamped on the engine information plate. When an engine is moved to a higher altitude, these settings must be changed by your Caterpillar dealer in order to prevent damaging the turbocharger, and to provide maximum engine efficiency. If the engine is moved to a lower altitude than that which is stamped on the engine information plate, the engine can be operated safely; however, it will deliver less than rated horsepower, and the fuel settings should be changed by your Caterpillar dealer to obtain rated horsepower.Stopping
1. Flywheel clutch operation: Quickly pull the clutch lever to the released position. For electric set operation, see the GENERATOR SET OPERATION instructions. For Woodward Governor operation, see the topic, WOODWARD GOVERNORS, Stopping the Engine. 2. Reduce engine speed to half speed. Run for 5 minutes to cool engine.3. Reduce engine speed to low idle.4. Observe the crankcase oil level while the engine is idling. Maintain the oil level between the ADD and FULL marks on the side of the dipstick stamped, CHECK WITH ENGINE RUNNING. See the LUBRICATION AND MAINTENANCE SECTION.5. Stop the engine. After Stopping Checks And Procedures
1. Fill the fuel tank. See the LUBRICATION AND MAINTENANCE SECTION: Fuel Tank Maintenance.2. Drain the raw water system if below freezing temperatures are expected; see: Draining Raw Water System.3. If below freezing temperatures are expected, allow the engine jacket water expansion tank to cool; then check the coolant for proper antifreeze protection. Add permanent-type antifreeze, if required.4. Repair any leaks, make major adjustments, tighten loose bolts, etc.5. Observe the Service Meter reading. Perform the periodic maintenance as instructed in the LUBRICATION AND MAINTENANCE CHART.
