Required Tools
A Stopwatch or Timer 1 Note: Before you perform this check, refer to Testing and Adjusting, "Machine Preparation for Troubleshooting".Use Table 2 in order to determine the correct cylinder cycle times. Choose the column that has the cycle times for your Motor Grader. Record the actual cycle times in the column that is on the right side of the table. The cycle times that are shown in Table 2 are in seconds. The number of steering wheel rotations from the left stop to the right stop determines the steering check.For most cylinders, a test cycle is the full range of movement. For the following cylinders, a test cycle is movement through a 305 mm (12 inch) distance: blade lift cylinders, ripper cylinder and scarifier cylinder. For the circle, a test cycle is 1/4 of 1 full rotation.All of the checks of the implement cycle times must be performed at high idle. The hydraulic oil must be at normal operating temperature. Ensure that the cylinder bears no additional loads. The following causes will create additional loads: interference from other machine components, contact with foreign objects and contact with the ground.If any test results are unacceptable refer to Testing and Adjusting, "Hydraulic and Steering System Troubleshooting".

(1) Cycle times are for a “running distance” of 305 mm (12 inch).
(2) Cycle time is through full travel.
(3) When you check the cycle times for these cylinders, operate the machine at high idle and place the transmission control (lever) in the FIRST SPEED position. The differential must be unlocked.Procedure To Check Blade Lift Cycle Times, Ripper (If Equipped) Cycle Times and Scarifier (If Equipped) Cycle Times

Raise the implement that needs to be checked to the maximum height.
Place a mark on the rod. Place the mark just below the cylinder head. Use ink in order to create all marks. Do not create marks by scratching or by scoring.
