Need some help from the Robart retract geniuses please. I have the 615 set in, won't hold air. Tested everything, found the leak in the left retract unit. Shaft leaks where it comes out of cylinder. Is there anyway to repair it, lube of some sort, something? Brand new, only thing holding me up from the maiden. The retracts themselves look kind of cheesy to me, has anyone else run into issues with them.
Trying to quit smoking and run down an air leak at the same time is, well it's testing me. Help!
Dan, the O-ring on the pistonis more then likely dry and allowing air to leak by. I had the same problem with one of my Robart retracts. I fixed the problem with pneumatic air tool lubrication oil.>>
Make sure the air pressure in the retract system is at zero PSI. Disconnect the two quick disconnects to the two MLG retracts, take a syringe and put a small amount of pneumatic air tool oil in the syringe. Inject a bit of the oil into the 2 air lines at the quick disconnects. You will see the oil in the tubing as it enters, you only require about an inch in length of oil showing in each air line.>>
Reconnect the 2 quick disconnects, re-pressurize the system, now cycle the gear full up full down as many times as possible. When the gear will no longer cycle due to low air pressure, re-pressure the system again, and recycle the gear until the air pressure is too low to cycle the gear.>>
Re-pressurize the system; take note of the air pressure PSI, leave the system pressurized for an amount of time that you feel is right, then re-check the air pressure PSI. The leak should have either stopped or at least slowed down. If the leak rate has slowed down, then inject more oil into the 2 air lines and repeat the process again. This procedure should stop your air leak if the faulty O-ring was only dry and not previously damaged, torn, cut etc.>>
Let us know if this method solves your leak problem, and good luck be with you
