I bought an original dual SCV set up to mount onto my 1020. Looking everything over they look alright with the exception of the QDs which are plugged up with mud, but the valve levers are extremely hard to move. One of them I can't move at all, and the other is extremely stiff. I haven't mounted it up yet to see if anything works. The stiff levers have me worried that I might need to open them up and do a rebuild on them. The tractor they came off of had a stuck motor, so i've no idea how long these have been sitting. How hard is it to rebuild the valves?
Or, would it be better to mount them up to the tractor so they fill up with oil and cycle them a few times and see if/how they operate? Thinking this might be a better route. Mount them, hook up the supply and route the return to a bucket. Im not crazy about routing the returns straight to the tractor and possibly introduce some contaminants to my newly cleaned out transmission. Thoughts?
