SPT343 Truck Mounted Pumper Caterpillar

There may be several ways to stop the engine. Ensure that the stopping procedure is understood. Use the following guidelines for stopping the engine.

1. Disengage the driven equipment. Unload the triplex pump. Refer to the "OEM Operation Manual" for additional information.

2. Adjust the "DECK RPM CONTROL" switch that is located on the Universal Remote Control Console to low idle. Refer to this Operation and Maintenance Manual, "Universal Remote Control Console" for additional information.

3. Set the gear selector to the NEUTRAL position.

4. Increase the speed of the deck engine. The speed must be between 1000 and 1200 rpm. Run the engine at no load for 5 to 10 minutes. This will allow the following situations to occur:
   • The lubricating oil will carry the heat away from the turbochargers. This will prevent premature bearing failure.

   • The engine coolant will distribute heat from the engine evenly through the cooling system. This will prevent cracks in the cylinder heads.

5. Decrease the speed of the deck engine to low idle.

6. Permit the deck engine to idle for at least one minute.
