| -6- Also we deepened the grooves machined in the pads which we found were not quite to their standard depth. A slight leak of oil from the junction of the central lubrication feeding the front axle may have helped the insufficient quantity of oil being supplied. We have however, since making these small recesses, had no sign of the steering becoming heavy, and examination of the ball ends and pads has found them to be well lubricated after a long run. We have already fully reported this to Derby. SIDE STEERING TUBE TO L.O.P. F.80566.- We have examined the side steering tube and found the front and rear ball ends amply lubricated. The springs do not show any sign of having set up and are in a good condition. RADIATOR TO L.O.P. E.80827 (Staybrite finish). INCORPORATING N.S. 3059 SINGLE POINT SUSPENSION. Lec. 2799 DOUBLE ACTING THERMOSTAT RADIATOR SHUTTERS. I.S.3062 SHALLOW TOP TANK. THERMOSTAT OPERATED SHUTTERS. Using: E.80634 Bottom Tank. E.80578 Inlet Nozzle E.80615 Studs. Ex. 5039/40 Washers. Ex.5041 Spring. Ex.5042 Dist: Piece. RADIATOR SHUTTERS TO L.O.P. E.80986 INCORPORATING Lec 2799 DOUBLE ACTING THERMOSTAT.- The radiator has remained very steady throughout the mileage. Examination of the centre point mounting shows it to be still in a good condition, with no sign of any weakness or fracture. Very little wear has taken place in the controlling washers for the studs. The double acting thermostat for the radiator shutters has operated at a temperature of 70/75°C. in opening the shutters. There is a fair amount of lag in the shutters closing, a slight stickiness is chiefly due to this. Water has been lost from the radiator chiefly through the shallower top water tank, there being less room for expansion of water, consequently more water is passed through the steam pipes than previously. It also creates more splashing of the water, which is splashed down the steam pipes. We have found that very little water is lost if the radiator is filled to just cover the tubes when the water temperature is approx. 75/80°C. No water can be seen on the top of the tubes when the water is cold. The top inlet nozzle also causes a bad swerving of the water, which in the first place hits the front portion of the top tank, afterwards swerving round in the direction of the filler cap. This action tends to throw water down the steam pipes. BONNET.- The bonnet remains very steady at the front, but chatters and lifts considerably at the rear, due to the movement of the frame. The rear bonnet clips do not appear to have sufficient load to keep the bonnet steady. We have not had at any time any of the bonnet fasteners become detached. | ||
