Greetings Gents - I should take delivery of my rebuilt bucket cylinder for a JD 490D this week (finally). I am thinking there is no need to bleed out air in the steel line/barrel... Would anyone disagree?? Thanks, Mark
No Argument from Me ! …… LOL It might be spongy for the first few strokes (cycles) but that will be gone in very short order …...
That all depends on what it is lol. Two days ago I helped a local farmer change the wing fold cylinder on his 40ft dmi cultivator and when done I said now go start the tractor and let me bleed the air as you move the lever. He said I have never done that before in my life it will be fine so I said whatever you say and proceeded to watch him sheer off two 5/8 bolts and destroy the wing wheel assembly as it crashed to the ground the moment it over centered Sent from my SAMSUNG-SGH-I317 using Tapatalk
On a BKT Cyl you are ok but there are some cases that it is a must to bleed them. I watched a guy destroy a yarder by lowering the tube right after he replaced a cylinder w/o bleeding it. If it's an application were there is a free load on it, I will cycle the cyl back and forth a few times before I pin the rod in.
I usually just run them slow and in increasingly longer strokes until I reach the end of the stroke
