WHEN ORDERING YOUR SMITHS SPEEDOMETER
Remember that all bicycles are not alike and to ensure that your cycle speedometer will be easy to fit and the installation neat in appearance, correct particulars should be given with your order.
CALIBRATION. State whether dial markings are required in miles or kilometres.
WHEEL SIZE. Various driving gears are supplied in accordance with the front wheel tyre size, i.e.: 30-Tooth for 28 in. tyres, 28-Tooth for 26 in. tyres, 26-Tooth for 24 in. tyres. Always state the size of the front tyre with your order.
MOUNTING DETAILS. The standard speedometer is designed for clockwise rotation with the driving gear and pinion bracket on the right-hand side as seen from the saddle. Where a brake drum or dynamo hub is fitted on the right an anti-clockwise instrument is supplied together with a left-hand pinion bracket.
Most bicycles have a register for the location of the front spindle on the inside of the fork; the pinion bracket is then fixed between the spindle nut and the fork as shown by diagram A below and it is frequently necessary to insert a special packing washer as indicated to provide sufficient clearance between the driving gear and the fork. When the register is on the outside of the fork end the bracket should be fitted inside the fork and packing washers used if necessary to obtain the correct driving gear clearance (See diagram B).
Please specify whether right or left-hand mounting is required and if packing washers are needed.
DRIVING GEAR FIXING. For tandems having large hub flanges the standard driving gear may be used but special clamp plates and fixing nuts are required as shown in diagram C. The plates are supplied without extra charge when ordered with the speedometer.
LENGTH OF FLEXIBLE DRIVE. Always specify the length of flexible drive required. As a guide, the average lengths are as follows:—Roadster with 28″ wheels and raised bars; 26″ drive. Light roadster or sports model with 26″ wheels; 23″ drive. Light roadster with straight frame and 26″ wheels: 25″ drive. Racing model, with 26″ wheels and dropped bars; 21″ drive.
When measuring the length of drive required, remember to allow for curvature of the cable so that it can be clipped to the fork.
Where the register for wheel location is inside the fork the pinion bracket fixing is between the nut and fork, special packing washers being used to increase the distance at X to provide clearance for the driving gear, if necessary.
DIAGRAM “A”
The pinion bracket is fitted inside the fork end when the spindle register is provided by the nut. Plain packing washers are employed to obtain clearance if required.
DIAGRAM “B”
For tandems with large hub flange the driving gear is secured with four special clamping plates to bridge the openings.
