SERVICE
MAIN DRIVE SHAFT BEARINGS
Main drive shaft bearings are greased by 2 of the remote zerks in grease bank under the step by the
mill cover. For bearing replacement, follow steps 1-5 from the previous
Belt Replacement section in this
chapter. Then:
1. Disengage PTO, shut-off tractor and remove key.
2 Remove the hydraulic pump belt shield.
3. Release the spring tension on the hydraulic pump drive belt.
4. Remove the hydraulic drive pulley on the end of the main shaft.
5. Remove the drive chain to the transfer shaft.
6. Remove the PTO.
7. Remove the flywheel and flywheel clutch.
8. Remove the back left flywheel shield.
9. Remove remote grease lines from bearing blocks.
10. Remove main driveshaft cover with shaft and bearings.
11. Remove shaft and bearings from cover.
12. Loosen set screws and remove bearings.
13. Install new bearings and tighten set screws.
14. Reinstall components in reverse order.
15. The bolt securing the PTO to the shaft should be tightened to seat
the bearings. Then back the bolt out and tighten to 6-10 inch lbs.
of torque. Secure the bolt with wire to PTO yoke.
MILL THROAT PLATE
The mill throat plate must be properly adjusted to hold the screen in place when the mill screen cover is
closed and latched. Adjust the throat plate position with the two bolts on each side of the mill housing. To
adjust the throat plate:
1. Disengage PTO, shut-off tractor and remove key.
2. Open the mill screen cover and install a screen into the
screen support.
3. Loosen, but do not remove the four adjustment bolts
and position the throat plate toward the bottoms of their
mounting slots, then partially tighten the bolts.
4. Close the mill screen cover while forcing the screen
against the throat plate.
5. Before latching the cover, tightly secure the four
adjustment bolts to lock the throat plate position.
NOTE:
The throat plate position should be adjusted regularly to maintain proper mill/screen operation and
cover latching, and to prevent material from dropping out the bottom of the mill.
