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 speed tests, the bucket must be empty.
Move the machine to an open area so that the bucket can be fully raised.
Perform the torque converter stall test in order to verify that the engine is developing adequate power.Reference: For more information about performing the torque converter stall test, refer to the Service Manual module Troubleshooting and Testing and Adjusting, "Torque Converter Stall and Implement Pump Double Stall - Test" for the machine that is being serviced.
