you may have to resort to sizing up the orings,seals and wipers by size alone. If its a simple double acting cylinder like I think it is,Baum should be able to help you.Good people there that know hydraulics.Ask 'em to send you a copy of the 1in thick 'Redbook'-its their catalog of hydraulics parts and everything else they have..Otherwise you might have to replace the cyls with something else close to what was original..maybe cut end mountings off the old cyls and reweld onto new cylinders from surplus center for example. Hope this doesnt snowball on ya Sonny.

Another one is Messick's.com,they have some parts listings for the 1530,with hydraulic parts listed.Looks like a cylinder kit for the lift cylinders is 99.00ea,but check for content and compatibility.
