HYDRAULIC DRIVE SYSTEM Speed Setting Procedure Reduce Pivot Radius Tracking Procedure *Goal is to match the Forward speed of 10 MPH and reverse speed of RH control. Set Engine RPM to 3600 RPM. Adjust RH control rod to ensure forward ground speed of 10 MPH. • Hub RPM = 175 RPM • RH turn of control rod to reduce speed • LH turn of control rod to increase speed Move RH control to Forward position and record ground speed. Figure 28 Move RH control to Reverse position and record ground speed.
HYDRAULIC DRIVE SYSTEM If the right hand transmission has been replaced, repeat tracking procedure of a new machine. 1. Set forward speed on right transmission to 175 RPM, record value. (LOCK CONTROL ROD WITH JAM NUT, NO FURTHER ADJUSTMENTS ARE MADE TO THIS SIDE) 2. Move right control to reverse, record value. 3. Move left hand control to forward, record value. 4. Move left hand control to reverse, record value. 5. Use tracking program and tool to determine how to adjust control rod and pivot radius.
HYDRAULIC DRIVE SYSTEM Bleeding the Hydraulic System The traction system is self-bleeding, however, it may be necessary to bleed the system if fluid is changed or after work is performed on the system. 1. Disengage the PTO and set the parking brake. 2. Stop the engine and wait for all moving parts to stop before leaving the operating position. 3. Raise the rear of the machine onto jack stands high enough to raise the drive wheels off the ground. 4.
