They are not difficult to work on if you know what you are doing technique wise, straight forward really. But you say you are going to do a top end rebuild and change the main bearings. What about the big end? You need to decide if you are going to take the engine completely apart....or fudge around. ? Quote Link to comment Share on other sites More sharing options...

I think you need a press to Change them? Quote Link to comment Share on other sites More sharing options...

To an experienced person its still a big job but not that challenging. Yes you will need to use not only a powerful press bur also some good alignment tooling and press tools, together with dti’s and vee blocks on a surface table.

I have always sent my crankshafts to a machine Shop for big end repairs. But i don't thing is needed if the gaps are okay. Quote Link to comment Share on other sites More sharing options...
