Title: Need to replace little end bushes?
Post by: rowan.bradley on 07.11. 2017 19:47

If my block has been rebored, and I am fitting new pistons with new gudgeon pins, is it normally necessary to fit new little end bushes?

How much play/float (which I suppose I will try to measure with a dial test indicator) is acceptable between the bush and the pin?

If they need to be replaced, can they normally be pushed in with a vice or nut and bolt or other stuff lying around in my garage, or do I have to have someone with a proper press do it?

And having fitted new bushes (if this is necessary) do they need to be reamed? If so, is this something that I can do at home if I buy the proper reamer? Can I use an adjustable reamer? Or is it something that needs special equipment?

Thanks for your help - Rowan

If you can’t rattle the pins up and down in the bushes, leave them alone.
