If you took any photos during your rebuild, they wouldn't come amiss. :thumbsup:
Sorry I should have, removing the cylinder I removed air lines, and c-clips on inboard side of the mounting baskets, then crawled under the coach and took inboard nuts off the mount for inboard brackets, took cylinder to my vise and clamped with the fittings up, (marked with a sharpe for orientation) and removed them, then took my pick and rotated the barrel until I could get the pick under retaining ring there is a hole by the fitting and twisted the barrel and rolled the ring out, removed the barrel off the head and replaced the o-rings used red tacky grease on wear points (o-rings) and reassembled, reinstalled
Thanks
Mike
