EXPERIMENTAL REPORT. -4- Expl. No. REF: Hs{Lord Ernest Hives - Chair}/AJL/LG30.3.25.

ADJUSTMENTS CARRIED OUT.

BRAKES.
Front brakes 3 notches each side.
Rear brakes " " " "
Servo nil.
Hand brake nil.

Cross steering tube ends adjusted up 4 times.
Front shock absorber arms adjusted up 3 times.

TAPPETS. Adjustment required very little attention. Should be set at .002" dead-cold or .004" hot, if adjusted up closer than .004" hot, the valves will be open when the engine is dead cold.

CLUTCH. We find minimum allowable clearance in the operating levers should be .040" when cold - these keep their clearances well. Clearances decrease as clutch temperature increases. We find that best clutch brake clearance is .035".
