7.4.3 Removal of gearbox
Removing the gearbox can be made easier with the surfacing arm removed (see
section 7.4.2) but it is not essential to the operation
To remove:
1. Observe all Warnings and Cautions; refer to sections 3.1 and 7.4.
2. Push both selectors on the gearbox fully in i.e. the direction selector to the
'OUT' position and the feed selector to the
‘N’ position (see Fig. 9).
3. Remove the surfacing arm. This may be left in position but removal will make
the task easier.
4. Remove 4 off M10 cap head screws from gearbox housing.
5. Firmly grip the gearbox in your right hand, ensuring the keeper plate is secured
into the gearbox as this prevents the output shaft from pulling out of the
gearbox as it is eased away from the hub. Do not allow the traverse direction
selector to pull out of its position or this may result in the spring loaded drive
key being lost or displaced.
6. Draw the gearbox assembly off the location dowels and clear of the input and
output support bushes.
7. Place in a clean safe location.
8. If the drive key becomes displaced it will be necessary to remove the selector
shaft and gears. To do this remove the black anodised handle and securing
nuts, remove the keeper plate and securing screw before withdrawing the shaft
from the gearbox (consult the gearbox drawing in parts list) and locate the drive
key. Inspect the springs and replace if any damage is visible.
To refit
To refit follow the removal procedure above in reverse. Do not forget the gear
selector shaft stop sleeve. When inserting the sub-assembly into the gearbox
rotate the gears on the shaft to allow them to mesh more easily. Refit the keeper
plate and securing screw.
7.4.4 Replacement of shear pins
To replace either shear pin follow the procedure:
1. Remove the gearbox as described in section 7.4.3. The shear pins will be
found in the worm shaft and in the output shaft.
2. To replace a broken shear pin in the worm shaft unscrew the three retaining
screws and remove the bearing cap.
3. Withdraw the worm shaft, drift out the broken pin and refit a new shear pin.
Ensure the broken sections of the original shear pin are removed from the
gearbox and check grease for contamination and foreign elements.
