I would disagree with that also:) It is quite easy to incorporate an external battery box into the hab heat scheme…

No lithium. Circulating heat down to the batteries is not all that difficult…

Yea I am putting that tank under the bed or couch/bench and elevator bed platform to gain a little more useable living space. I am going to keep the batteries down on the chassis, so the concept of getting the tire down onto the chassis REALLY appeals to me, even at the cost of 10deg of exit...

Was re-visiting the spare location as it is getting close to time to make those final design decisions. If I am willing to lower the rear exit angle to 30deg, I can get the spare tucked up under the rear end, with all its weight suspended from the main truck frame structure. In a captive...

Typical ag/light industrial hydraulics run under 2500PSI. The cylinders are sized to deliver the required force within the max system pressures allowed. I think those are about 2.5” cylinders, with a 1“ rod? With 2500PSI, they would push with 12,300# and pull with around 10,300# of force...

That sounds like low fluid. The hardest part of the lift is the first 1/3, so every seal and fitting is at it’s highest stress before that point. Above about 1/3 it gets significantly easier. TheAOP is up between the air filter and the spare. Its filler plug/dipstick is toward the front. The...

The tire is just so dam bulky:) The space between the leaf springs is only 40”, I think you will have a problem fitting the spare up over the driveshaft anyway. I was looking at an idea to put it on an angle up under the rear and still keep it inside the exit angle, but that was also...

I don’t think the ring, gun and ammo weigh as much as a tire… and even with that weight, they add a cab support strut to the windshield center. You are also not trying to remove the ring, gun and ammo(gunner doesn’t count:)) alongside the road on a dark and stormy night with a crane you need...

Things start to get complex when you start to move weight up… That is a large bulky tire, about 350#, that you now must lift, move horizontally far enough to clear the cab then lower now at least 10’. lot of added stresses with overhung loads, and the design is critical. This is not even...

Yea that's all i am using(pump and flow control valve), my spare is relocating also…

I jink some have done just that, using an oring kit…

The AOP is OK, but it and the manifold have their fair share of issues. I find it hard to believe your hand pump is bad… I am removing that mid structure so dropping to a hand only was a good decision for me, and also keeps inline with my KISS policy. i have used that type hand pump on dump...

The control valve cores are segmented by orings. A bad seal could let pressure pass right from inlet to outlet and have trouble building enough pressure to do the work… capping the outlet on the hand pump will prove if the hand pump is indeed bad. You should not be able to pump into a...

Well it is about 4X too big, which means it needs 4X the cable size and will pull 4X the current needed to actually do the job, while sending 3/4 of the fluid thru the safety relief valve. The 0.8 GPM is I believe a typo based on the KW rating and the port size, and farther down in the...

While looking up another part today I came cross these 3 port “L” configured ball valves. A pair of these could be used to control 2 cylinder circuits from a single pump, like the dual selector I showed in the drawing above(Would just have to move 2 levers). At $32 ea, a pair of these would be...

Oh, and I like it a lot…

I think the empty cab is around 1600#, so another 600 is +37%? Where that weight is located will make a large difference in lift requirements If you are keeping tire crane: The tire lift is about a 50% increase in pressure(2100psi) over the cab lift but still well under the pump capacity and...

If you drive the truck, you probably will:). There is a guy out toward salt creek that has some, so it was probably him

I don't think so, i do work for the county, but havnt met anyone in the parking lot… did you have your truck with you?

I was asked about a drawing for using this pump for both cab and tire lift. This drawing, and the parts described assume re-using the JIC4 hoses that are already on the truck. If you change hose end type, you will need to change adapters accordingly. The hand pump and the dual selector valve...
