| X3873 RHC.{R. H. Coverley - Production Engineer} Hs{Lord Ernest Hives - Chair}/Les.9/KW.6.6.34. 22-EX. Will you please :- (i) Fit a 3/4" dia. roll rod at the rear to replace the present 7/8" dia. rod. (ii) Fit a 3/4" dia. roll rod to the front of the chassis. We attach a rough sketch of a suggested arrangement. (iii) Cure a bijur oil leak in the rear cross member. This has caused the O.S. rear shackle to become dry. Under these circumstances we think the O.S. rear road spring should be dismantled and greased, so that we can carry out useful springing tests. Hs{Lord Ernest Hives - Chair}/Les.{Ivan A. Leslie} | ||
