| R.R.A.160-1 15M-2-1-23 45625 ROLLS-ROYCE OF AMERICA, INC. SPRINGFIELD, MASS. PROPOSED STANDARDIZATION OF CHASSIS PARTS No. 28 To Mr. Belnap The following is proposed: PIECE NOS. AFFECTED: S.S. G-6501 SECTION NO.: 6060 NAME OF PARTS: Epicyclic Gear on 2nd Motion Shaft DESCRIPTION of Alteration: To cancel bush G-3518 in sun wheel shaft and reduce bore of sun wheel shaft to provide guide for pull rod. PURPOSE of Alteration: With the use of grover washer for the nut on the sunwheel spindle which holds the chain sprocket, there is no definite means of preventing the bush G-3518 from pulling out, except its tight fit in the shaft. Movement between the pull rod and bore of the spindle occurs only occasionally, at low speed and under no load. We have never seen any sign of wear between the spindle and the pull rod. We therefore suggest that bush G-3518 is unnecessary. Alteration No. 4274/A Date January 11, 1924 Signatures implying agreement with the alteration: NAME INITIALS DATE Mr. Olley OY 1/11/24 Mr. Nadin TN 1/12/24 Mr. Bagnall GB " Mr. Hulley WHH " Mr. Southern JS{Mr Johnson's Secretary} " Mr. Caswell EWC " Mr. Ross Mr. Beaver HCB " Mr. Belnap LJB " Mr. Harkness THH " Mr. Royce Mr. Johnson We propose to put this alteration into regular manufacture on March 1st, 1924 unless we hear from Mr. Johnson and Mr. Royce to the contrary. Tested: Not tested Estimated cost: Slight saving. Proposed Chassis at which alteration should start: 802 Cost of parts scrapped, if any: none Increase in weight, if any: none. | ||
