Yea more volume, but the larger piston area will do the work at a lower pressure, so less strain on the AOP… Very nice!

It is going to go on the back of the habitat box I have planned. I removed all that hardware for the tire crane, lifting arch and air filter/exp tank, so I could build the habitat right up close to the back of the cab so I can fit a pass-thru. The air-filter is going up on top of the cab. The...

IDK, but have sure come across it a lot on the forums. Mine locked up once. Was able to free it, like most people, by repeated up and down cycles. I think the real trick is after you pump up, which should release the safety check, you need to release the pressure very very slowly so it flows...

All the ports on the hydraulic system are SAE-4. They use SAE-JIC adapters to match up to the JIC-4 hose ends… Once you remove the screen, hollow Allen spring retainer and outer spring, You could probably unscrew the check ball seat using an easy-out, or drill it out, to remove the seat, ball...

In the video up at comment #38 in this discusdion, my system took i think 2100PSI to lift the tire. A 2" piston with a 1" rod has about 2.35sq/in of piston area in pull. Multiplied by 2100PSI, thats just shy of 5000# of pulling force to lift the tire with that horrible geometry... Getting a...

Yea they usually wont move at all when the safety is hung up. It isnt still chained down is it:) If it moves, that sounds more like a clog at the control valve orifice. If you loosen the fitting facing to the rear of the truck on the cylinder, and you can move it further than 1/2" and fluid...

There is a safety check ball in the cylinder base. It is held off of its valve seat by a spring. The fluid flows around the ball and past the spring. If the flow gets to fast it compresses the spring and the ball seals and locks the cylinder. This check works with the restricted orifice in...

Or you have gotten air in the cylinder. Because of the angle that cylinder sets at it is succeptible to the inconsistent flow caused by air pockets in the oil. This can cause the cylinder to lock in the up position as the load/safety check gets pushed against its seat and held there by the...
