SIMPLEX TIMING CHAIN SINGLE ROW

Single row timing chain as fitted to every A series engine until the twin row duplex gear set was introduced on Cooper S cars.

Check your timing gears for wear and if need be upgrade to a duplex kit C-AJJ3323. 

Please note: the cam gear with the tensioner rings was superseded by the plain gear which is the only type available.
