11. Re/1WW.3/WR.10.9.37.

Exhaust Fittings LOP.E.1046.
Exhaust blow occurred from the middle joint and on the cylinder head. This was due to the manifold distorting so that the middle flange had drawn away from the head approximately .040". The threads of the brass nuts had pulled out as a result.
The special front stays of the front expansion box were not satisfactory.
These points are receiving attention.
The silencing was up to the usual 25/30 standard and no trouble was experienced with the system.

Starting Handle LOP.EH.711.
The handle did not line up with the crankshaft. This trouble was also experienced with the raised front engine mounting on 6.B.IV. in France.
A general re-design of starting handles is in progress.

Dashbrackets & Fittings LOP.F3.1194.
Bonnet LOP.BB.75b.
FN.864/8/9/90 Strips 'Kansas Snubber'
The Kansas tape cut into the aluminium bonnet and is not satisfactory. The side hinge pin on the near side worked out and thumped against the scuttle. Special plugs and taper pins were fitted on 32-EX. to overcome this trouble. These are required on this bonnet.
The downward extention of the bonnet side strips had not sufficient clearance where they pass above the frame, and had fouled.

D.W.S. Hydraulic Jacks.
These were satisfactory and the position of the front jacks better than Phantom lll.
