I just bought a MEC 9000H, and setting up the hydraulic unit has been a nighmare.The directions are some of the worst written product instructions of any kind I have ever read.

To begin with, the schematic of the hydraulic unit does not resemble the unit supplied me. I discovered this a few weeks ago, on a weekend of course, so I had no one to call until Monday.

I generally work during the week (like quite a few other people), so it is not always convenient to call technical support while sitting in front of the machine. Finally I spoke to someone and sorted out the erroneous schematic.

Today, a few weeks later, I finally got around to pouring in the oil, and was even more amused by the instructions.

In one paragraph the directions say that one quart of oil is sufficient to operate the machine.

In a later paragraph it says that the oil should reach the fill line (which one quart of oil does not accomplish).

WHICH IS IT???????????????

I tried it both ways, and still the machine does not work. The motor hums along merrily, but nothing happens when I depress the pedal.

I am not exactly new to the 9000; I own three 9000Gs, but this thing has me stymied.

Any similar experiences?

I had the valve indicator in line with the valve, but after your suggestion I unscrewed the cock as far out as I could. It made no difference. The manifold on the hydraulic unit has two hose ports. I attached the hose to the one on the back (opposite the pedal) as shown on the schematic. Still no good.

shootnclays,

I have no such instructions. I am a little worried about disconnecting the hose at this point, under pressure, with oil in it. Ideas?

open the cap on the resivour,and reinstall it.

I understand the other, but why do I need to do this?

I got the oil to come up to supply hose (enough to make a nice mess). But then I connected it back up and nothing.

Did it twice.

Nothing.

Thanks. I was beginning to think that the problem was something like that. We will be talking to the boys at MEC tomorrow.

On top of the pump you have two threaded holes, both have a screw in plug--remove the plug closest to the foot operated pump switch and put your hose in that hole. Remove the the air return cap(the tall plastic screw in cap) and screw it in the reservoir fill hole, you can add a little more oil than the supplied quart to the reservoir but I didn't fill mine all the way up to the line. Run and attach the other end of the hose to the top of the unit where the fitting is, I used plumbers thread tape to both ends of the hose, open the petcock screw. It is NOT necessary to bleed the air out of this hose as it will be pumping oil through it which will force the air out(no mess). It is extremely important to run the small hose attached to the bottom of the hydrolic unit down the main hose and insert it into the hole in the top of the tall plastic cap, this is a return line; your unit will NOT operate properly if this small line is not properly installed(WHICH MEANS- It must be vertical, no dips, from the cap up to the bottom of the hydrolic unit). Once you hook all of this up, you turn on the electricity, make sure the loader is indexed properly, then operate the foot pump lever 4 or 5 times till the line is purged. The unit should start operating, the new units will make a squealing noise which MEC says is normal, but to me it's almost like raking your fingernails across the blackboard!

Now the fun begins! be careful operating the unit it is powerful and has alot of power. It is mentally hard to stop the operating foot pedal once you initiate it's operation. Good luck! Biff

Well, I spoke to MEC and found out the problem. On the hydraulic manifold on the pump are two hydraulic ports. The instructions clearly show the hydraulic hose attached to the rear of these two ports.

The fellow at MEC laughed sheepishly and informed me that the directions were WRONG and that it should be connected to the front port.

He said, "I don't know why they don't change those directions."

Why indeed.

24 grams isn't that what I said in my post on how to hook up your hydrolic unit? I had been on the phone with MEC several times, some of them know how to trouble shoot the H and one I talked with knew less than I did. If what I wrote was of no help I'll be glad to delete it.

Shooting clays, the old pump had only one plug hole to go to the pump, the new pump has two holes on the top of the pump housing and has a clear oil reservoir. Biff

Biff,
Your post was great. Unfortunately you posted after I signed off last night, and I found out from MEC this morning before I read it.

Very good advice, just a little too late. Even if I had read it, I was ready to give up on the thing and sleep on it.

After changing ports, it works like a champ.

Any one use it with other gauges interchangably?

Yes, I've added quick disconnects to the hydraulic hose, and use it in a four gauge setup. The pneumatic quick disconnects work fine. I still have to manually connect the breather hose to the machine, but that does not seem to be too difficult.

Bob-k. I have 2 machines hooked up to 1 hydraulic pump and 2 breather lines coming off the pump. I just stacked 2 of the breather line fittings on the pump. Works fine. Stacking four might be less then attractive. Maybe you could drill another hole in each of 2 of those fittings to give you 4 ports. You'll need to buy the very small plastic line for the added hookups.

Great advice guys. Thanks. I know that if I ever need reloading advice I can go to the experts - trapshooters.

I added some 10-30W to top mine up some, I think it comes with 30W but don't think that is real critical as long as it is in that range. My new machine was super quick compared to the older one, I slowed it down by turning the petcock in where the upper end of the hose goes into the hydrolic piston, you do have some control there I found out.
