Designed to lock the camshafts on twin cam (multi-valve) engines in order to stop them rotating out of timed position during removal of cam belt. Incorrect timing can cause serious damage to inlet and exhaust valves due to contact with piston head. Saves time by removing the need to re-time the engine following cam belt changes. Colour coded, investment cast locking tools and precision-machined pins ensure accurate fit and aids quick tool selection. Supplied in carry-case with warning tag, instructions and parts list.
