Bar Nuthin 1,061 #54 Posted July 16 It looks like these adapters will work nicely to go from ORB-6 down to ORB-5. Any advice on how to purge the air from the system? I'll probably finish assembling tonight. Share this post Link to post Share on other sites

I'll probably finish assembling tonight. Should self purge. Just use the up/down a few times and drive around. Check and top off fluid. 2 Share this post Link to post Share on other sites

Once I get it working good, I think I have engineered a way lift my MightyMac (engineered in my head, at least) 1 Share this post Link to post Share on other sites

Bar Nuthin 1,061 #58 Posted July 17 (edited) I will need to take it apart again to address a small leak at the end of the cylinder, but it's not so bad that it can't wait awhile. Somewhere on the site is post on a hack to add an external o-ring and washer. Also needs a proper roll pin for the handle. All in all, a much easier project than I anticipated.

In order to fit the mechanicals into the small space on the tractor, WH decided to use the “retract” motion of the cylinder rod for the “heavy” lift. This puts more fluid pressure on the rod end of the cylinder and works that O-ring seal harder. 2 Share this post Link to post Share on other sites
