I realise this is an old thread, but I just ordered some European Shape couplers from McMaster, they were all CEJN 320 Series(made in Sweden). The ID of the plugs measure right around 0.300". Hawker

You guys have any tips for installing the cylinders back on? I have the rods/ pistons installed on the crank. I considered removing the pistons and installing them in the cylinder first. I tried to take one of the wrist pins off and it seems to be very stiff in the rod and I don't want to risk...

Found a picture of how the tank was plumbed originally, the small tube in the middle actually goes about 3' down into the tank. I don't know what that was for, if anyone knows, please fill me in. Also the 2 copper tubes coming off the check valve in the manifold, one goes to the CPR, but I...

Getting ready to per her back together, do you guys try and seal the threads of any bolts going into the crank case? I honed the cylinders and they cleaned up ok, there is some rust pitting on one of the low pressure cylinders, but I'm going to try it and see what happens. There are some...

That is one thing I notice with Mastercraft stuff, the quality varies alot, and it seem to me like a trend. They seem to keep making things cheaper until they get too many returns, then the quality go up a bit before the cycle repeats.

Not Warranty per se, but still interesting to see the process. 1 Mastercraft Maximum 2 Adjustable Pliers -The tool was unfinished, they missed a step in manufacturing and didn't add the serrated jaw faces. 3 Canadian Tire Retail Store 4 Hassle Free but pointless. 5 I found the pliers(image...

As Citation said, the pressure switch is adjustable. Tightening the nut on the larger spring will increase the cutoff pressure. Adjusting the nut on the smaller spring will change how much the differential pressure, which seems to be fine at around 30psi. Since you have a smaller motor on there...

Also, a 7.5 hp is an awful big motor to run off that pressure switch. Did it come with a mag starter?

Glad it worked, I did see one for sale today that show different plumbing.

Back in the day(2000) with my first truck I had to learn to change u-joints, so I picked a lifetime warranty 3" vise, which was all I could afford and on sale for $10. I to tried to press out the u-joint, snapped the casting while cranking the handle. I returned it and they upgrade it to a 4"...

I don't have a manual, or any experience with the Dresser, but i'll tell ya what I think since no one else has replied. If it is set up to turn on and off, looks like the unloaded on the pressure switch should be connected over to the port in what I think should be the check valve. And then add...

Thanks 850, I was thinking something along those lines. Sorry for the hijack RT.

EDIT:Looks like guy48065 beat me to the explanation of the spring loaded handle, see above. Here is a selection from Mcmaster, all M10X1.5 by either 20 or 25mm long) if you weren't able to find them on there.

I like the screw piles. They come in different sizes, and around here, they are the same cost per pile. If you beams can handle the span, you can use fewer piles(assuming locals codes allow). They guys who installed mine was a 1 man crew, and done in 1 hour and they were all exactly where I...

So I'm starting to put this back together, and I must be missing something, but what? The tank has two 3/4" npt ports on the top, one had the manifold in it (pictures below) and the other had an adaptor and a 1/4" copper tube going about half way down in into the tank, maybe 3ft. What would be...

I've heard good things about the reliability of the Rolair wheel barrel style wheeled units. They are fairly expensive though.

It would be good to have a 20 amp circuit if you are going to do that. I used to run a 15 amp compressor on a 15 amps circuit and spent alot of time walking over to the breaker box.

I haven't been able to figure that out, I liked the house that came with it. When I was house shopping, it seemed like OSB was used in all kinds of places it shouldn't be, in my town. My guess is that, there were a couple OSB mills in the area, so it was cheap.

For today I lapped the valves bodies today and that was way quicker than I figured maybe 10 minutes to get nice smooth sealing faces. So then I went to have a look at the CPR. The little brass lever that actuates the release valve was moving when spinning at a constant speed, so I figured there...

All the pistons have seem to have STD stamped on them, so they seem to be original. I measured the HP bores to be a around around 1.750 +- about 4 tenths. I'll try rocking the HP pistons again, but there didn't seem to be any play, I didn't slide the wrist pin back and forth though. I don't yet...
