Place a 25.4 mm (1.00 in) ball of putty (or similar material) on the front of the frame stops.2. Start the engine and raise an empty bucket approximately 305 mm (1 ft) off the ground. Disengage the parking brake.3. Place the engine at high idle and steer rapidly into both stops.4. Steer the machine into the straight ahead position and engage the parking brake. Stop the engine.5. Measure the thickness of the putty. The putty must be pressed to 19 3 mm (.75 .12 in).6. If necessary, adjust the strikers until this dimension is correct.Supplemental Steering Diverter Valve
