Workshop Manuals

The Workshop Manuals are photocopies of extracts taken from various editions of a book written by Mr. Waller, the Ariel factory service manager. They are not restorers’ guides, nor are they a full manual; as they were written in the 1950’s they do assume that you have a complete machine that you wish to service or repair and are ideal for this, having a list of most of the settings.

Singles – Covers all models 1938-58 except specific differences on the competition models. For the 1956-58 HS/HT models use this with OG56HS. This is also useful for earlier models, especially if used with the relevant Owner’s Guide. WM38SING

Twins – Principally covers the 1948-57 KG/KH 500 twins, Burman gearbox and the cycle parts. The Huntmaster engine is not well covered; the Haynes manual, see below, or the BSA service sheets (00-8006) are recommended. WM48TWINS

SQ4 4F/4G – This version covers the ohc 4F 1931-36 and the iron Square Fours 1937-48. The ‘Cammy’ engine is not covered in any great depth; see the Owner’s Guides for more information. WM33SQ

SQ4 MKI/II – For the owner of the 1949-58 all alloy Square Fours WM48SQ

FH – The well known Haynes manual for the A10 is very useful for rebuilding the Huntmaster engine which is structurally the same as an A10; it is only the engine casings that differ. Part number WM47A

GB gearbox – A booklet by Burman’s on ‘How to dismantle the GB Gearbox’, it does also tell you how to put it together again! Part number OG52GB

Solex carburetter – A general booklet on Solex carburetters of the type fitted to the 1937-53 Square Fours. It covers maintenance and tuning rather than full overhauls. Part number OG37SOLEX

Electrical – This is a small hardback reprint of the ‘Motor Cycling Electrical Manual’ originally published in 1963. It covers all types of motorcycle electrics, with the theory and practise simply explained. Highly recommended, but unfortunately no longer available! Try Ebay.

Lucas – This is a proper manual including testing procedures for all Lucas equipment used on machines fitted with dynamos, some electrical knowledge and equipment required. Part number WMLUCAS DYNO
