Be careful to assemble the pin so that the side hole (branch hole) is on the link tread side in the same way as before turning. 2) Not only a bushing but also a seal need to be replaced with new one at the same time when a bushing is replaced with new one. On the other hand, a bushing can be reused if there is no abnormality even if a seal is changed with new one. And bushings and seals are not reuired to assemble as original set.
