It is not absolutely necessary for the removal of the surfacing arm to take the
gearbox off the hub; however removal will make the task in hand much simpler to
do.
Removal of gearbox
1. Push both the selectors on the gearbox fully in i.e. the traverse direction
selector to the 'OUT' position and the feed rate selector to the N position.
2. Remove the 4 M10 capscrews from the gearbox housing.
3. Firmly grip the gearbox in your right hand and with your left hand hold the
gearbox output gear. 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.
4. Draw the gearbox assembly off the location dowels and clear of the input and
output support bushes. Place in a clean safe place.
5. 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.
Refit of gearbox
To reassemble, build the selector shaft up as a complete sub-assembly with the
selector shaft fully in (the 'OUT' position). 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.
7.4.2 Replacement of gearbox
1. Ensure that no contamination has entered the gearbox.
2. Place some grease around the worm and gear and replace the gearbox.
Secure with the screws.
3. Check operation of direction selector.
