Shorting in carrying tube. 6) Brakes. Servo. S9. I9 recurrent. -------------------- 1) EXHAUST SILENCERS. The failure of the exhaust silencers are costly. In the last quarter at Cricklewood and 6 months at Paris, the cost has been Pounds 118.10.0. In view of this, we propose to get a front & rear silencer made in treated sheet iron to obtain the difference in cost. An effecient treatment is now obtainable for sheet iron. This would not interfere with the silencer noise and no new designs would be required. The difference in cost will be duly forwarded for your persual and permission to fit. 2) HYDRAULIC DAMPER KNOCKS. These have cost the firm at Cricklewood & Paris Pounds 39.0.0. The present chief cause of damper knocks is due to slackness of the inner bearing for the damper arm shaft. It has been found that a .008" clearance causes a knock. This has been taken up with the Works, Expt. and Depots. Care is being taken to ensure no slack in these bearings in production or replacements. Cast iron bushes are being experimented with. | ||
