| From Exp. Dept. Copies for: Mr Johnson. Mr Royce. Mr Spinney. Mr Nadin. Hor/Hy{Tom Haldenby - Plant Engineer}8/L9613. June 9th. 1913. Report on tests of Steering Pivots F.2353 - X.160 This is the medium type pivot. It is similar to C.402 except that it is slightly thickened up in the U. section. I believe it is fitted to cars from No.2075 to 2300. Two new pivots were tested and were run at a speed of 750 reversals per minute on the test rig. No. 1 broke in 2 hours 30 minutes. No.2 " "1 " 5 " These were the only new ones I could get, but I ran two second hand ones to destruction. They were not cracked at the start. No.1 broke in 8 minutes. No.2 " " 15 " G H Haldenby | ||
