Re: Steering center-link pin and bushing

Just an update... I did get my center link back from the shop and the machinist had a couple of interesting observations. The bushing has a squared notch on each end. Once it is inserted in the center-link, it protrudes slightly on both ends. There are 2 corresponding washers with flat spots on their inner holes that go over the top & bottom ends of the bushing, and the whole 'assembly' is slid into the frame. The pin is then inserted from the bottom and when the castellated nut is tightened down, it locks the bushing in stationary place and the center-link moves on the bushing as opposed to it being pressed into the center-link hole and having the bushing rotating on the pin. He said that is why the bushing has a grease hole in it and a slight indent around the outside circumference, so grease can GET to the moving part of the joint. This was all news to me but certainly answered my previous question about the 'double movement' of the connection which to me, did not make sense. The previous bushing was steel as opposed to the bronze or copper alloy the new one is made of, and a previous owner had machined it down, instead of reaming the hole in the center-link. In reducing the OD of the bushing, it had become too small for the notches on the ends to engage the spacer washers, allowing for it to rotate on the pin AND swivel inside the center-link hole. When I reassembled it and the washers fit tightly over the ends of the new bushing, it all made sense. Once everything was bolted up and the joints all greased, I have zero play in the vertical movement of the center-link and the steering is smooth and responsive. Can't wait to try it on the road once my new engine is in!!
