Just recently I bought another 5 BHP Petter Junior just to save it from the scrap heap really, anyway was looking for something to do Sunday and decided to to take a look at the old girl and low and behold I think its a viable engine apart for a big end bearing set!! Have looked all over the net and don't seem to be able to locate anything. Can anyone offer any help please? Kind regards Steve
They are not an off the shelf item. You need to find a local firm that can cast and fit whitemetal bearings.
You could try one of your local heritage railways e.g. the Bodmin and Wenford, etc. West Somerset Restoration on the west somerset railway, my local , take on work, but obviously not at the moment.
