Well if you take one off and fluid comes out of the port instead of the line when you operate the pump, you got the wrong one:)

also start your gremlin posts with year and version IE: 98 M1078A0...

I described a way. you need a pressure container with a valve though. I have used old gas cylinders and fire extinguishers for this to pre-lube engines and cycle cylinders. you can also use plain compressed air. 120 PSI X3.14 SQ/IN piston surface area = 360 pounds of force on the piston...

Is there fluid in the hand pump reservoir? There is a filler plug on the top left/front corner...

There are filters in the valve body, I believe at different locations depending on which valve model you have. There are flow limit check valves in the cab tilt and tire crane cylinders that are there to prevent a cab or tire falling in the event of a hose failure. There are restricted...

For towing with lifted front, it is easier to pull the rear axle shafts out thru the rear hubs. There is a big hex head cap(3"?) screwed onto the center of each hub if you remove it, you will see the end of the axle, it has a threaded hole in the end, you can screw a bolt into that hole and use...

H is 24V, R goes to the control solenoid, so you need to insert a jumper from R to H to close the control solenoid B is the supply solenoid. Once the control solenoid jumper is in place/solenoid closed, you will need to jumper H to B briefly and give a 1-2 second shot of supply air to...

You probably still have a leak somewhere. The controller closes the control solenoid and gives a shot of air from the supply solenoid on the PCU to open the dump and wheel valves to the PCU. Then it looks for a stable pressure reading on the pressure sensor on the PCU. If that reading is not...

That is a 7-8 PSI relief valve. The PCU uses it as a pressure regulator to drop the air in the system low enough that the dump valves on the frame open to release tire air to the atmosphere. The deflate solenoid opens the manifold to that relief which vents the manifold pressure down to 7-8 ish...

Ok, 94 means it is an A0 and has a cat 3116 engine. No glow plugs or intake air heater, only manually activated ether injector when the engine coolant is cold enough to enable it. The M1078 manuals you will find at the link I gave you are what you want. The back of the 20-1 thru 20-5 manuals...

Ok, well an A0 doesn't have glow plugs or preheat so we need you to positively identify this vehicle. What year was it made? What Model(A0 or A1) and What engine? The polarity protection box is designed to protect the vehicle from incorrect battery connection. If this is an A1 it will have...

What year, A0 or A1? Your description sounds like an A0 and All the A0 manuals are in the manuals section on this website in the present conflict vehicles section. There are 2 24V lines Off of the battery bank, one goes to the starter The other goes to the polarity protection box so it sounds...

A 6.6 Litre engine doesn't need a very large filter being run for maintenance/no load. I was planning on a maintenance filter with the same coupling I use for the riser duct...

I wont have an open intake:)

Cab tilt will be easy. One snap collar will separate the air pipe under the cab and up she goes. I am also planning on putting the expansion tank up there:) I am certain I can make a better use of space with box and steps there and the tire pushed to the rear(lower overall length for a given...

I am going to put my factory can on the roof...

I would get a straight 24 and one of Supermans 100A surepowers... There was quite a discussion on the quality of the double-alt not all that long ago. In the end pulling 12V out of the middle of a 24V string and trying to charge 12 and 24 simultaneously is a problem prone way of doing a dual...

Well if you are putting in rated pressure and don't have fluid spraying anywhere, that is your lift limit of the rams. With segmented/telescoping rams, you don’t get full force out of them until the largest segment(largest cross sectional area) starts moving. Those are pretty big rams. Hows...

Maybe, can you get one of those for $3500? lots of cool info in the ECU engines, Unless the ECU has crapped or been swapped in the past:) How many ECU’s,have we heard about dropping their memory because their internal battery has failed... I am sure a few have failed before they were surveyed...

No, if the engine was cold enough(below freezing), you have to push a switch on the dash(top row second from left I think) to get it to spray ether into the intake to help very cold starts...
