With regard to the fact that Mr. Hancock points out that the .038" holes in the high pressure valves were deleted we would like to remind you the present position, which is as follows:- (1) R.H. 40/50 HP. - No leakage holes in the valves. (2) L.H. Chassis. - .038" holes in front and rear damper valve (one hole front and two holes rear). (3) 20 HP. CHASSIS. - .031" hole in the rear damper valves only. The above refers to high pressure valves only, low pressure valves being undrilled. BY. {R.W. Bailey - Chief Engineer} | ||
