With regard to the clutch to N.Sch.3575 that you are detailing for us, will you please arrange for the spring to allow a torque of 2150 lbs.in. instead of 1960, i.e. increase the load of the spring from 312 lbs. to 343 lbs. This will allow for 120 M.E.P. which we are obtaining on the J.1 unit. Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls} | ||
