| Constant Mesh Gears, backlash - .005 2 nd Speed Gears, actual backlash - .003 3rd. " " - .004 The excessive backlash in 2nd & 3rd Speeds is partly due to the wear on the flanged bushes of 2nd & 3rd speed gears. Servo Motor. Nut G.52138 and Operating Lever F.56946. Badly indented on thrust ball race track. Friction surfaces and linings - general condition good. Propeller Shaft. General condition good. Trunnion very slightly marked by needle rollers. Rear Axle & Brakes - Y-4-BE-56 11-43 ratio (Production Axle) The following points were observed on dismantling the axle and brake gear for inspection- Total backlash through all gears, splines etc. measured .100 at propeller shaft bolt centres. Backlash in wheel and pinion only .020 at propeller shaft bolts (originally .010) A considerable quantity of dirt and mud had found its way inside the brake gear and there was a thick coating on the friction surfaces of the hand brake straps. There was a certain amount of oil inside the axle tubes at the centre casing end but none on the axle shafts or in the brake gear. One of the brake strap fulcrum distance pieces GB.2021 was rusted to the fulcrum bolt and also seized in the brake straps. This distance piece was apparently fitted before the practice of cadmium plating was introduced in order to overcome this trouble. The front brake actuating shafts GB.1105/6 were starved of oil and rusted into the bearing brackets G.101148/9 Lubrication of this shaft depends upon priming with oil during assembly, the oil feed connection being remote from the end which tends to seize in service. Strip Condition of Axle & Brake Gear - Bevel Gears. Pinion GB.798 Wheel GB.405. Gears were set up on production rig for re-lapping following the usual practice with repair axles, but | ||
