The Ariel Shop Manual explained:
Two publications make up the "Ariel Shop Manual". The first is the spare parts list for the correct year and model Ariel. The second is "Ariel Motor Cycles" by C.W.Waller, service manager Ariel Motors Ltd. The "Waller" book was published in North America by Floyd Clymer under the title "Ariel Motorcycle Owner's Handbook". Copies of both these books are often found on ebay and similar places while reprints of sections can be obtained from Draganfly (link below) and others. A third very useful resource is Modern Motorcycle Mechanics by J.B.Nicholson (link below). MMM contains a wealth of practical workshop information for servicing Ariels and their components.
Other helpful documents include the Draganfly Catalog with it's many diagrams, the Lucas "Workshop Instructions" for servicing electrical parts and Ariel's "Owner's Guide" for the appropriate year and model. Publications and articles on Burman gearboxes and Amal carburetors are also helpful.
Ariel Motors did several things that make restoration of their bikes easier. First, Ariel established a policy of interchangeability so that when parts were redesigned they could be fit to the older machines. This obviously doesn't work for all parts, but it does for many. Second, the last two digits of Ariel part numbers signify the year the part entered production: thus 1750-29, 1750-34, 1750-39, 1750-51 and 1750-54 are all single cylinder camshafts produced from 1929 through 1954. Despite the 5 different designs they are all interchangeable (though you need different followers with the last two versions). Third, in addition to a picture and a part number, Ariel parts lists show casting numbers that can be used to identify parts. These qualities make the Ariel parts lists an indispensible resource. Parts lists and other technical publications are found in the "members" section.
