| -2- Hs{Lord Ernest Hives - Chair}/Wst.1/MA.16.12.33. Cont'd.{John DeLooze - Company Secretary} The cause of the failures experienced is therefore due we consider to insufficient clearance between the bush and the pin plus a slight contracting effect due to the bushes not being properly cured. The drawing only shews a clearance of .001" with a max. limit of .001" which means that in the extreme limit only .002" clearance is available. This should be altered immediately to shew a minimum clearance of .002" on the minimum limits. Hs{Lord Ernest Hives - Chair}/Wst. | ||
