    What makes a MEC 9000H grunt and groan near bootom of cylinder cycle?

    Cleaned the collett, loosened the collett, the adjustable bar stops about 3/16s
    of an inch short of the bar cycle.

    Never had this prolem before.

    The moaning is the noise of the pressure rise and the relief valve opening up and dumping excess pressurized oil back into the reservoir. The sound is normal.

    Toolmaker it is not making a complete cycle. Could it be caused by low oil level?

    Make sure none of the linkage is loose or bent, and look at the end of the hydraulic cylinder which has a thread on it. See if the cylinder is not unscrewing from the clevis which operates the linkage.

    I have Auto-Mates, but the diagnosis procedure should be the same. Operate it slowly, watching and looking for the station or area of resistance. Try cycling without shells in the plate, and with the charge bar without bottles lifted well out of the way.

    Try lowering the charge bar mechanism and observing. Also try loading one shell slowly at a time, which is certainly possible with a 9000, and inspect for resistance from each station.

    I have the same loader and notice a hissing noise---I thought is was oil level but not---It starts when I 1st start loading then seems to stop---might have air in the line---

    I have the same or similar problem with my 9000H and the people from Mec, at the grand last year, said to lubricate the main internal column which is accessed from the rear of the machine.

    Let me know if it helps, haven't gotten around to trying this yet. Good luck.

    Now let me see a 12:49 PM you create a thread that is titled

    "Reloading Problem w/ Winchester Super Lite"

    At 12:54 PM you create this thread saying that your machine is not making a complete cycle. You are now being advised to work on or at least check out hydraulic for problems.

    Well back in the day when Superlite powder was just coming out I had a MEC no 9000 no hydraulics. The Superlite would get under the bar and cause it to hang up and make very light drops. The MEC I was using was a 650. When I pulled the return spring off the charge bar and removed the bottles I couldn't move the charge bar by hand there was more powder between the bar and the frame than there was in the bottle.

    I couldn't move the bar with my hands when I drove the bar out and cleaned the powder out the machine worked flawlessly for a little while. I would suggest that you make sure that this is not your problem before you start doing things to the hydraulic system.
