You have just prooved you 'can' teach an old dog new trick's,
that's an idea that I had not considered and may be possible if the person that drilled the original hole, did so "straight", as they used a drill size that doesn't allow for any wandering!
Roland and Harry,
I have tried these methods many times in the past with various jobs, with a good success rate and would have a go with either or both if required on this project, BUT.... someone has also broken the casting where the Check Chain assembley fits, trying to take out the studs that hold the check chain on!! So whilst not another bodge as such, maybe in-experience instead
Whilst I or we may be able to find a way around this particular problem, economics and time step in and say get another casting as these are common tractors and one is available from a friend.
I am sure that if these problems were encountered on a very old and or rare Engine or Machine with no chance of finding spare parts, then these methods suggested would be very much considered.
Great input gentlemen, this is what forums for me, are all about, learning from each other.
Thank's for your help.
