BOOM ASSEMBLY
STEP 3
NOTE: If only the boom pivot shaft is to be replaced, it will not be necessary to disconnect any hydraulic lines or lift cylinders from the boom. Connect an overhead lifting device to the rear of the boom. Use the lifting device to take up the weight of the boom from the pivot shaft. Remove the pivot shaft retainer bolt from the end of the shaft. Use a large brass drift and heavy sledge hammer or a hydraulic ram pusher arrangement to drive the shaft approximately half way out. Lubricate the new pivot shaft with antisieze grease. Install the new shaft into place. Using the old pivot shaft as a pilot, install the retainer bolt and nut. G0605057
