Hyd Cyl lag time?

[CCCLLC]

Replaced nipple fitting on loader arms cylinder. Can't  believe it has taken me this long to break it off. Can't believe I haven't cut it off with a misguided saw. Anyway, the fixed Cyl is not pulling it's weight. I know it is air mixed in there. Got to be hard on welds on arm with one Cyl not putting out 100 percent. Will this air work its way out?

[Skipper11A]

Yes.

Work it empty a few times and it should be fine.

If its a single acting cylinder like the ones we have on our sizzor lift, you may have to bleed the air out, but double acting(two hoses to each cylinder)usually deal with the air themselves....I think ;D

Crack the lines and bleed it.

Hello, 
   Cycle the cylinder a few times all the air will go back to the tank and be vented. Hydraulic fluid is not really special but it does not work well with tractor hydraulic fluid. Dextron III is the heaviest viscosity that should be used.

Thanks All!

In a hyd system with two cylinders hooked to the same valve through a tee fitting the pressure in each cylinder will be the same even if one cylinder is full of air. The cylinder w/oil will just compress the air till they lift equally so don't worry about twisting the frame.

After three days of sawing, still have a slow cylinder on log loader. Replaced a broke nipple and put it back to work. When I lower the loader empty for next log, the unrepaired one will raise up from ground , waiting for repaired Cyl.
   With loader at rest, can I remove top hose and fill Cyl to "top it off"? Am I just impatient?

You have a problem somewhere that is not going to "fix" itself.  Some Teflon tape somewhere it does not need to be, a collapsed or internally separated hose, something.  I would start with the last thing that you did and go from there.

Hello,
  I would guess ( I am guessing) that one of the pins is tight? Will they take grease? Or the loader is twisted. I have seen a few that one support leg will stay up until the other cylinder has traveled fully then the other support will lower. The leg that is slow, drive the grease able pin out and see if it may be tight.

Can the velocity fuses stand any heat. I'm wondering if the shop heated it up to get nipple. Loader takes grease well and always has. I can lift the loader by hand and it doesn't feel like it is in a bind. Took Cyl. and velocity fuse apart again and can't see anything blocking flow (Teflon). I can hear the ball or spring rattle in there. Normal?
