FRONT AXLE. On checking over the above axle following the second series of tests, it was found that neither the axle beam nor the pivot pins shewed any sign of distortion. Further to our RHC.{R. H. Coverley - Production Engineer}1/MS30.11.34, we give below particulars of the pivot pin distortion which took place during the previous tests when the axle beam was badly distorted.
