‘6 Spring Clutch’

This clutch is easily identified by the rather crude sheet metal centre. It is not very good and is often replaced by either of the 2 types of Triumph clutches listed later. It was fitted to ‘A’ swinging arm models from 1954 up to 1960 or 1961, depending on the model (see below), C10 and C11, ‘M’ from 1948 to 1963 but not the AA or alternator models, ‘B’ from 1946 to 1957 (i.e. not alternator models). The illustration is a composite drawing, i.e. not all of the parts on the drawing were used on all of the models.

The A group changed from a 6 spring clutch to a Triumph 4 spring type in the early 1960’s. The change took place on and after the following engine numbers: – A7 – CA7 8623; A7SS – CA7SS 8122; A10 – DA10 13298; A10SR – DA10R 2443. How to use the table: – Firstly find the ‘key’ number of the part you require on the drawing, then find your model at the top left of the table, move across until the correct year is found. Move down that column until you are in line with the relevant key number on the left and select the part number of the one that has a quantity shown in your column. Use the part number to order, the quantity shown is the number used per bike. Check for any notes appended to the description, as some applications are complex, see the push rods!
