I'll do that Case, I got the centre rollers pulled out and started on one of the side ones, Because I am not sure of its history we are going to replace all the roller bearings, It could be a bit of a job unless there is an easier way to get the hyd motor off the end of the roller. I found the locking grub screw but the side one doesnt want to come loose, so i went and did a bit os spraying while I thought about it.
