KIT-METERING PUMP 3282073 - Caterpillar

Sudden movement or accidental starting of the machine can cause personal injury or death to persons on or near the machine.To prevent personal injury or death, perform the following:Park the machine on a smooth, level surface.Lower the work tool to the ground and engage the parking brake.Stop the engine and remove the key.Block the wheels and install the steering frame lock.
The implement cycle time can be checked in order to verify a complaint about slow implement speed. This test will also help to determine whether all functions are slow or only one function is slow.Note: For all cycle time tests, the work tool must be empty.Machine Preparation
Perform the torque converter stall test in order to verify that the engine is developing adequate power. For more information about performing the torque converter stall test, refer to the Service Manual module Testing and Adjusting, "Torque Converter Stall - Test" for the power train on the machine that is being serviced.
Perform the calibration of the main control valve in order to ensure that the solenoid valves are functioning properly. For more information about performing the calibration, refer to the Service Manual module Testing and Adjusting, "Main Control Valve (Electronic Technician) - Calibrate" or Testing and Adjusting, "Main Control Valve (Operator Monitor) - Calibrate" for the machine that is being serviced.
Move the machine to an open area so that the work tool can be fully raised.
Shift the transmission to the NEUTRAL position.
Warm the hydraulic oil to normal operating temperature. The hydraulic oil must be at a temperature of 68° 14°C (154° 25°F) in order to obtain accurate results.
In order to receive an accurate cycle time, the implement hydraulics must be placed in the service mode. In the service mode, the lift, tilt, and auxiliary functions will operate. Most of the control features will be disabled. Note: Float control will not be disabled.Reference: For more information about initiating the implement hydraulic service mode, refer to the Service Manual module Testing and Adjusting, "Implement Hydraulic Service Mode" for the machine that is being serviced.Cycle Time Check

Raise Lower Float Tilt Back Dump
8.5 0.5 4.4 0.4 4.1 0.4 4.1 0.4 3.3 0.4 RAISE
Move the work tool to the full TILT BACK position.
Lower the work tool completely.
Increase the engine RPM to high idle.
Move the lift control lever to the RAISE position. Hold the lift control lever in this position until the lift cylinder reaches the end of travel. Record the amount of time that is required for the work tool to travel from the ground to the full RAISE position. Refer to Table 1 for the correct cycle time for the machine that is being serviced.LOWER
Position the work tool so that the work tool is flat on the ground.
Raise the work tool to the maximum height.
Increase the engine RPM to high idle.
Move the lift control lever to the full LOWER position and hold. Note: Ensure that the lift control lever is NOT in the FLOAT
