The ram fails to lift the jack. Unloaded it goes up, but If I put 160lbs (me) on it, it goes down. I know tubing flare fittings form a metal to metal seal, but much softer metals. I think I'll try an O-ring down there.

I've got this old Sears 2 ton just about figured out. Turning the handle feeds the square core down on a ball bearing. Is that bearing supposed to seal against the metal seat below? There is no O-ring down there (or in exploded view diagrams I've seen). That seat appears to be a solid part of...

Thanks! I'll look for a primary connection cable. All but one cable to the swing arm are plugged in. The one labeled "Trigger" with just two pins is missing. The electric cables for the two lower modules are accounted for. I think the battery cable is only needed to power the timing gun, but...

Found the calibration gas port. It would make sense if the valve selected either cal. gas or test (exhaust) gas, but I can't find a switch that opens the left (facing into cabinet from rear) valve port. Even if that was the correct port for cal. gas, I am back to needing a second T to connect to...

In better light I saw there are two discharge ports in back. One for water and one for exhaust gas. I rerouted the gas discharge to the back port and ran a long line for water, out the water port which probably never had a fitting. (I previously thought it was missing.) The gas module runs...

I slept on it and I have a better idea. I should have been thinking vacuum instead of pressure. The intake of the 2nd pump goes to the top (outlet) of the 3-way valve. The vacuum switch (I previously called it a pressure switch.) connects to the lower valve inlet on the closest side. The main...

Just putting this out there. It looks to me like the plastic T-fitting is for joining the two discharge hoses. (Curiously, the T is larger dia. than all the other fittings.) One discharge hose from the light tube (Need to lift entire module.) and one from the cabinet vacuum pump. (The pump...

I might have the logic figured out, but it would require two T fittings. I only found one in the cabinet. Are two required?

You were probably asked this many times. Could you repost these gas hose pics or provide a link? Thanks!
