I have a grain bed with hoist for my 1 ton. I figure most of the little bolts don't work with these, so that's why I posted on the Big Bolt.

Looks like a while back the PO broke the single hydraulic cylinder "lever hoist" and replaced it with two telescopic cylinders direct lift. Yeah, this is real overkill.

The surfaces are a bit rusty on one of the cylinders. I've never rebuilt this type of a hydraulic cylinder before and would prefer to send this out if it's possible. Is this something that I can take somewhere and have them refurbish / fix / etc... What else should they work on while I have my cylinders there? Would they also have the capability to rebuild the pump and valve? What kind of shop should I look for to send this to?

Thanks, and any help is appreciated.
