Smoooooth operating retracts
Hey guys,
I have installed a new set of ROBART RETRACTS in my H9 P-51. I have a flow control valve on EACH of the retracts so I can set them independantly to operate as smooth as possible. Now, after many years of being an industrial maintenance mechanic, I have been stumped by a set of pneumatic cylinders. I can not seem to get these to operate as smooth as I want. I am thinking that after a little use, the O-rings will loosen up a bit and they might work a little smoother. I am also thinking that I may need to pull them back out real quick and lube all places where friction may be present.
How do you guys get them to operate smoothly? Any suggestions?

RE: Smoooooth operating retracts
Since air will compress, every itty bitty tiny spot of drag will stop the retracts until the air can overcome it. The only way to get perfectly smooth operation is to not restrict the air. Of course then they are too fast and slam open and closed. They will get a little better over time but will always be a bit "notchy".
