No difficulty should be experienced in
reassembling the gearbox, the procedure, in general,
being the reverse to that employed in dismantling it.
The following points should, however, be noted:
DRIFT FOR DRIVING GEAR
BEARING
Fig. 88.
(a) When assembling the layshaft gears on the
shaft, make sure that they are in the correct order.
Note that the layshaft small gear (18 teeth) is
wider than the layshaft third gear (21 teeth) and
that the splines at one end of the layshaft are
correspondingly longer. The layshaft second gear
(27 teeth) is fitted next to the small gear and the
first gear (32 teeth) next to the third gear pinion.
(b) Assemble the layshaft and gears, camshaft
with operating forks and mainshaft sliding gear in
a cluster before assembling these into the
gearbox. When doing this note that, if the layshaft
small gear is to the left, the pinion on the end of
the camshaft must be to the right and the small
end of the mainshaft sliding gear must also be to
the right. The small operating fork engages with
the mainshaft sliding gear, the larger one with the
layshaft clutch.
