5. Remove the broken head end of the shear bolt if it is still in place.
6. Rotate the PTO shaft by hand to align the sheared bolt in the sprocket plate with
either of the two holes in the inner hub.
7. Once aligned, use a hammer and punch to drive the broken part of the shear bolt
out of the sprocket plate.
8. Insert the new shear bolt from the front of the inner hub and install the nut on the
back.
9. Using the rotor drive belt, rotate the driveline to see that the auger drive turns freely.
Rotating the belt clockwise from behind the machine will rotate the auger in the
normal direction; counterclockwise will reverse the auger which may help to clear
any obstructions.
10. Replace the chain guard and rear upper guard. Close the auger clean-out door.
11. Reconnect the PTO shaft to the tractor.
12. Start the tractor engine. Engage the PTO slowly; be sure that the auger is turning
and allow it to clear all the grain from the GrainVac body.
If the shear bolt breaks again, repeat the above process, being sure to determine the
cause of shear bolt failure.
