Note—It is advisable not to remove gearbox from frame until the former is dismantled as difficulty may be experienced in holding it.
First remove kick-starter crank by unscrewing nut on kick-starter crank cotter and tapping out same. Then turn kick-starter pedal round twice clockwise (this unwinds spring) and withdraw kick-starter crank. Then withdraw clock spring cover taking care that spring remains in cover, otherwise difficulty may be experienced in rewinding the clock spring.
Should it be necessary to rewind spring, place same on peg in end cover then place crank on kick starter shaft and fully wind by turning crank until spring is fully wound. Tie wire round spring. It may then be re-inserted in box and wire withdrawn.
Remove the brass cap B3 covering the end of the Gear shaft, remove the nut B50 on the end of the gear shaft BK5-3 with a box spanner. Loosen the screws holding the cover plate. The cover plate can then be taken off. It is well to place a tin to catch the oil which will run out unless it has been previously drained off. Remove the driving chain, and withdraw the shaft.The middle gear, the layshaft andthe low gear are then all free to be removed for inspection. Provided that the wheels are not badly worn, there should be very little requiring attention. The kickstarter should be examined, and if there is a tendency for this part to slip, it can be remedied by fitting larger size rollers. We have various size rollers rising by .005" from .375 to .400 Too large a roller will not allow the kickstarter to free itself, but always use the largest roller possible. See that the springs and pegs which push the rollers into action are in good order.
The latest type of kickstarter is actuated by 2 rollers, which we find gives satisfaction in every way. Owners of machines fitted with the single roller type of kickstarter mechanism can obtain the 2 roller type (which is interchangeable) for a nominal figure.
