The following is a brief outline of the programme discussed to investigate Ph.III steerings :- 35-EX. (1) Try the bump buffers removed. (2) Check internal friction as well as is possible without dismantling. (3) Put the car in the fitting shop, dismantle and remove shock dampers completely. At the same time check if there is any excessive friction in the wishbone bearings, or if the spring is rubbing against the case. (4) Having eliminated all internal friction, rebuild with the spring packed up and no shock absorber innards. 36-EX. (5) (1) Eliminate lift to the shock damper valve. (2) Rig up Hartfords off the roll rods to see if a small amount of dry friction will improve the friction. (3) Try the variable rating pendulum lever. (4) Ultimately we propose to fit the La{L. A. Archer} Salle steering to this chassis. Bumper. (5) In view of the success of test (2) on 35-EX, repeat on 36-EX. See if it is possible to get a useful record of road shocks by means of the joggle meter on the bumper. Tune the "Hairpin" drop arm to find worst frequency for system.
