Hi all a quick update I've now fitted the new chain which seems to be a lot better in quite impressed with it , and I've tested the new steering which also works quite well I do however need to make a few adjustments to the steering bracket which fastens to the axle ! Here's a quick video
Since fitting the new axle it has picked up the front end up thus lifting the middle axle and making the middle axle air Bourne so I have now got to split the tractor and re drill the axle mounting plate to level up the tractor
