________________________________________ Replacement of wear parts 11. Remove the four (4) 1” bolts, flat washers, lock washers, and nuts from each of the headshaft bearings. Note that there may be bearing shims under the bearing. If shims are present, make note of their thickness, quantity and location. 12. Attach an appropriate lifting device to the headshaft and slide out towards the rear of the frame. WARNING! You could be seriously injured or even killed by falling loads. Observe the safe working load limits of lifting or blocking devices and keep a safe distance from suspended loads. How to install the headshaft To install the headshaft assembly proceed as follows (Fig. 78): 1. Attach an appropriate lifting device to the head shaft and slide in the slots located at the end of the feeder breaker. The gear reducer may be installed on shaft if desired. 2. Reinstall bearing shims, if applicable, back into the same location as they were removed from. Make sure to install the shims of the same thickness and quantity. 3. Align the head shaft bearings with the mounting holes in frame and secure each with the four (4) 1” bolts, nuts, and lock washers. Torque bolts to 645 ft-lbs. NOTICE! After tightening the four (4) 1” bolts and nuts and before installing the gear reducer, ensure that the headshaft can turn freeely by hand. If it cannot, loosen the nuts and bolts and add or remove shims between the frame and the piloow block base as required. WARNING! The headshaft must turn freely by hand or the bearings will fail prematurely. 4. Install the left and right sprocket guards, head shaft filler plates, tailpiece hoppers, amd tailpiece tilt cylinders (see Tailpiece installation procedure). 5. Connect the central lubrication hoses on both head shaft bearings. 6. Install the hydraulic motor onto the input shaft of the gear reducer. a.
