8.4 GEAR REPLACEMENT
SEE FIGURE 23 ON THE FOLLOWING PAGE.
1. Remove the drain plug (A) from the head casting and allow the fluid to drain.
2. Remove the motor from the head.
3. Remove the four bolts (E) from the bearing retainer (F).
4. Remove the worm shaft assembly (J). The worm shaft has a 10mm threaded hole in the end of it for
a slide hammer. This is the preferred method of removing the shaft. If you do not have a slide
hammer, the shaft can be removed by driving it out with a brass drift pin.
5. Inspect the worm shaft, drive gear and bearings for wear.
6. After the worm shaft has been removed, remove the three bolts (M) from the bearing housing (O).
7. Remove the spindle shaft (N) with a slide hammer. This shaft can also be removed by driving it out of
the head casting with a brass drift pin.
8. Remove the snap ring (R).
9. The brass worm gear (Q) can now be pressed off of the shaft.
10. Check the condition of the bearings and the seals before re-assembling the head.
11. Check the condition of the key (P) and the key-way in the gear and the spindle shaft before pressing
the new gear onto the shaft.
