R22 Occurrence at Biggin Hill
Ed Thrust 1V. Thanks for the reply. I am interested to find out how, apart from locking the head up solid by overtightening the main teeter head bolt, how the head could be seized especially if the shims were missing. Without the shims I guess the head could be squeezed in and could rub against the sides of the shaft, but the gap seems too large for this to occur as there is sufficient room to move the head across to set the head laterally. As the robinson head relies on a spanner type action of the spacers against the faces of the shaft, I thought it just may be possible to bend the main teeter bolt sufficiently to make it difficult to remove. I have worked on these heads hence my interest. I do not doubt what you stated is correct I am curious as to how it can occur. Many Thanks Bug.
