| RR 755 REVISED (10H) (DE 649 9-12-26) BM. 2/1187. Completed 22/7/27 STANDARDISATION of CHASSIS PARTS. Date 22.6.27 Description of Parts. FRONT AXLE TORQUE CONTROL. X No. 8420 / 7420 Drawing No. F.76482 Part List (f) Origin. To increase safety of brake application and enable flexible front springs to be employed. Experimental Test Report. Run 100 hrs. on the bump. Enables pivot lean to be maintained more consistently. Road Test Report. Run 5,000 miles on 12-EX, 10-EX and EAC.7. Marked improvement in steering control under brake application. When this device is fitted, we can then if desired, use weaker front springs and greater % of front braking. It is not proposed to alter either of these under this sheet. Scrap and replace at all costs, including Chassis already delivered to Customers. Scrap and replace on Chassis in Works. Scrap present stock and replace on all Chassis not yet handed to test. Use existing stock Alteration effective on future Chassis. Weight of Old Part. Cost of Old Part. £ 39. 19. 6d.

Certain parts are to go forward but some require improving for an orderly, satisfactory accessible job. FHR. (See memo.) WOR.{Arthur Wormald - General Works Manager} | 22.6.27 | Agreed. Wor.{Arthur Wormald - General Works Manager} RG.{Mr Rowledge} | 22.6.27 | Agreed. Rg.{Mr Rowledge} DA.{Bernard Day - Chassis Design} | 25.6.27 | Agreed. It is understood the exhaust pipe can be modified to get more clearance. DA.{Bernard Day - Chassis Design} BY.{R.W. Bailey - Chief Engineer} | 23.6.27 | Agreed. BY.{R.W. Bailey - Chief Engineer} EP.{G. Eric Platford - Chief Quality Engineer} | 23.6.27 | Agreed. EP.{G. Eric Platford - Chief Quality Engineer} E.{Mr Elliott - Chief Engineer} | 28.6.27 | Agreed, with modified exhaust pipes on engine particulars of which are now being fixed. E.{Mr Elliott - Chief Engineer} PN.{Mr Northey} CWB. | 23.6.27 | Agreed. CWB. This is considered a most important proposal and constitutes a very great technical advance.
