oldeng24he French term for "adjustable wrench" is "clé anglaise" or "English wrench". There is good reason for this, because older British machinery used a different set of standards, called "Whitworth" for wrench sizes and screw threads. Some of these sizes are close enough to Metric or S.A.E. sizes that you will be able to use your normal wrenches, but you will probably need to use an adjustable wrench as well. | oldeng24he French term for "adjustable wrench" is "clé anglaise" or "English wrench".

oldeng24efore you start to work on an English 3-speed (or a low-end English 10-speed), you should figure out who made it. By 1962, Raleigh or its parent company, Tube Investments (TI bought Raleigh in 1960) had gobbled up most of the smaller English manufacturers. In their enormous Nottingham factory, they built bikes under many names. It is important to know whether a bike was built by Raleigh because the Raleigh bikes were built to Raleigh dimensions, and other English bikes were built to British Standard dimensions. | oldeng24efore you start to work on an English 3-speed (or a low-end English 10-speed), you should figure out who made it.

oldeng24ost front wheels can be installed without regard for which side is left and which side is right. This is not the case with Raleigh 3-speeds. Raleigh front hubs usually don't have cone locknuts. Instead, they have one cone with wrench flats, the adjustable cone. The other cone is round, with no place for a wrench. The non-adjustable cone is supposed to screw down all the way on the axle until it runs out of threads (there is a raised shoulder on the axle for this purpose). All adjustments are to be made with the adjustable cone. The fixed cone must go on the bicycle's right, the adjustable cone must go on the bicycle's left. On the left side, the axle nut will keep the left cone from loosening up. If the wheel is accidentally reversed, so that the adjustable cone is on the right, it can tighten itself up and ruin the hub. | oldeng24ost front wheels can be installed without regard for which side is left and which side is right.
