| -2- 12) Oil Filter. Gauze filters - instructions all clear. First 50 Chassis in 'A' Series. All items as given above. Same answers apply. Chassis 51 Onwards in 'A' Series. 13) Cruciform Frame Member. No changes contemplated. - Instruct as first 50 chassis. 14) Change-gear Mechanism. It will not be possible to say whether the isolated gear-change mechanism is of material advantage before the time comes for releasing instructions for these chassis. This section should therefore be as the first 50 chassis. 15) Flywheel and Clutch. Instruct as the first 50 chassis. 16) Engine Coupling. No change contemplated. - Instruct as first 50 chassis. 17) Change-speed Gear-box. Continue with 50% fine gears and 50% coarse gears. 18) Hydraulic Jacks. See No. 1). 19) Hand-brake Shoes. Instruct as first 50 chassis. 20) Hand-brake Adjustment Mechanism. It is felt that the improved hand-brake mechanism recently instructed should, if possible, be incorporated on these chassis. This item is held up pending results of tests. | ||
