| 606 SECRET To BY. {R.W. Bailey - Chief Engineer} Copy to Bar. Rm. {William Robotham - Chief Engineer} WHS. Re Wraith II Front Brakes. The scheme showing the design of the Wraith II brake carrier plate is shown on N.Sch.4813. It has been pointed out to us that with the new camshaft having felt dirt excluders it is very difficult to assemble the camshaft and bearings in the brake carrier plate because the two halves of the carrier plate at this point are riveted together. We agree to the use of quarter-bolts in the place of rivets, the outermost bolts in each case being fitting bolts, the remainder being clearance bolts. Would you kindly instruct this modification.
