TRACK FRAME ALIGNMENT
51. TRACK FRAME ALIGNMENT (Fig. 14.43)
WARNING! Before working at the machine, be sure that the blade and ripper have
been lowered to the ground, engine is OFF, the drive train control lock lever is in
locked (ON) position and parking brake is set. The starting switch and the electrical
system master switch are turned OFF, keys are removed and the controls are
tagged to prevent inadvertent engine starting.
IMPORTANT: Disconnected hydraulic lines must be properly capped with the correct size plastic
cap. If caps are not available, use tape or rubber stoppers. Openings must never be plugged with
rags. This practice could introduce dirt or lint into critical hydraulic components. Remove all dirt
accumulation from the main frame cover. Tag disconnected lines to facilitate faster and correct
installation
