| (6) GOVERNOR CONTROL FOR DAMPER LOR.F27072. (1) A stronger main release valve spring is required in order to obtain the 6 lbs. higher release pressure called for on N.S. 4187. (2) Provision should be made for retaining the filter in the bottom of the Filter spout F.87084. REAR SPRINGS AND FITTINGS. LOR. FB6591. The overall length of the poundage plate requires shortening .300 to allow for rear spring piston F.86029 to bed properly. SPRINGING MAIN CONTROL MECH. LOR. G81623. (1) The dowel G.82304 was sweated in housing G.82343 to prevent any possible leakage of oil. (2) It is suggested there should be retaining rings on the bolts for the Valve cylinder housing G.81549. (3) N.S.4177 calls for lightening holes in the Crossmember distance pieces, but these are not shown on the detail drawing F.86094. (4) The stud bosses on the face of the main housing had to be reduced as shewn, to clear the idler lever. The shoulders of the main lever also fouled inside the housing which had to be relieved slightly in order to obtain maximum travel. (5) When SpectreCodename for Phantom III I Suspension was dismantled recently it was found that the strain on the F.84873 studs which pass through the frame had caused them to work loose in the main housing.
