External Type
Remove the foot gear lever and the cover plate immediately behind the lever. Move the outside striking lever on the gearbox until second speed or third speed is engaged, either of these positions may be used for adjusting purposes. It will be possible to feel the pawl in the gearbox click into the notch in the camplate as the gear is engaged properly.
Disconnect the ball joint at the top end of the gear rod from the foot change ratchet lever by undoing the hexagon nut which secures it to the lever and tap it out of position. It will be found that it is possible to move the end of the ratchet lever about 3/8" up and down between two points at which it will be felt to come solid against the operating pawls. It is now necessary to lengthen or shorten the gear rod until when it is connected up to the ratchet lever the ratchet lever is exactly midway between these two points—this is particularly important.
The cam plate which is fitted in front of the ratchet plate can also be taken off and it will be possible then to see that there is an equal amount of free movement on each side between the notches in the ratchet plate and the two pawls. The position of the foot gear lever after reassembly is adjustable for height to suit the rider by means of the slots in the lever. The bolts securing the lever must be very firmly tightened up, and when all is correctly assembled put a quantity of Grease into the foot change grease nipple until it starts to ooze out. Occasional application of the grease gun will keep all internal parts lubricated and exclude mud and water. Lubricate the ball joint and the knuckle joint occasionally with oil. No other attention is necessary. Do not take the device to pieces unnecessarily. Particularly do not remove the centralising springs as it is very difficult indeed to replace them without special tools.
All orders for spares or repairs for external type footchanges must be addressed to :—The Scott Motorcycle Co., Shipley, Yorks.
Internal Type
The foot gear change is now all enclosed in the gearbox and embodied with the striking mechanism. This requires no adjustment and none is provided. The position of the foot lever can be varied to suit different riders by loosening the nut on the top ball socket and moving the lever up or down as needed. The lever can also be adjusted for reach by loosening the clamping bolt which secures the foot lever to the centre of the operating lever on the gearbox. See also Note on Page 8.
