You should see something on the tcase drainplug if it is that C6 thrust bearing. Allison wants a small fortune for that composite washer:O

Well its connected to the TCU because thats where the speed signal comes from(output speed sensor down in the transfer case). The signal also feeds the CTIS controller that counts pulses to trigger its overspeed response. Since you have more than halved the pulses from the trans at any given...

In the end its a cat tune, so it is as probably as safe and reliable as any other cat product run at that level of output:) How hard you run things ultimately comes down to you...

Once the pump is pushing fluid, it does not take all that many pumps to make anything move if things are working right. again, this could be as simple as the hoses are connected backwards on one of the pumps… that is a good idea to confirm pump operation, connect a cylinder directly to the...

If the hand pump pumps fluid out its pressure port, it shouldn’t take all that long to prime/fill lines and start building pressure/doing work. The hand pump is sealed/has no vent port. As the hand pump pushes out fluid, it pulls a vacuum in the reservoir and should draw fluid in from the AOP...

Yea its got about a 4’ dipstick:)

step 1 establish you have a source or pressurized oil. Even if the AOP is shot, and they often are, the hand pump should work, they are pretty robust units, but also easy to test. Remove the line from the lower port on the hand pump(pretty sure that is the output) cap/block its output and see...

A scangauge D might also be able to read and display the bussed data, as well as deliver live consumption/mileage info.

well if both pumps have fluid yet neither pump loads up, i suspect the valve probably has a bad seal and is leaking from pressure side to return side… you remove the handle and there is a nut to unscrew the core to access the seals…

That suggestion from cat sounds a little off to me, at least based on what I typically observe… for economy, the engine is usually operated on the front side of the power curve, not the backside. For instance my truck and 4runners make pk hp at ~4800, pk tq ~3600 but highway cruise @60MPH...

Well of course it is energy, But you can take RPM out of the equation. I only need mention RPM in the sense that there is a particular one in a given engine configuration where the engine can produce peak torque. You have a certain gear ratio and a certain amount of torque which in conjunction...

No he is not kidding. You need to block the cab if you are ever opening the hydraulic system with the cab raised. There are safety check in the cab and tire cylinders, that should block the flow if it starts to move too fast. I have tripped mine lowering the cab too fast on my adjustble...

A seized safety check would still allow the pump to build pressure, (hydraulically locked, handle doesn’t move). If you can pump with little resistance, either you are trying to pump air(reservoirs empty) or something is allowing fluid to go from supply to return. which brings us to the second...

You should still know how to hook up a primary gauge. Good houses have good foundations and baseline fuel pressure is the foundation of this process. Often overlooked, but a fairly common source of problems. Unit injectors rely upon it and can be damaged if it is not right.

Don’t have the pneumatic canceling cylinder hooked up to the brakes yet, so its a little sketch…

Three hoses off the top of the tank, supply, return, both are JIC6 fittings. The vent port is farther forward, smaller and on a hose barb fitting…

Torque IS what does all the work. HP is simply an expression of torque over time and represents the speed at which you can perform a particular task or the volume of work in a given timeframe. it was an expression of energy output created by james watt to sell steam engines to people who had...

There is a test port on the fuel line between the lift pump and the fuel filter mounted to the side of the engine. Connect a snubbed/dampened 0-100PSI gauge there to measure baseline fuel pressure. Should have 20-25 at idle ramping up to 60PSI by peak torque RPM. any dips in that pressure are...

Thats one reason i went manual, dead easy. Two hoses, pump, adjustable flow control(for lowering speed control), couple of fittings and done. No wiring…. Uses plain common AW-32 hydraulic oil available everywhere… Totaled it up for someone last night, just over $250 in parts from...

Peak tq RPM is also know as peak volumetric efficiency. It is the point where you develop max tq output for the fuel consumed. It is determined by bore, stroke, manifold design and valve timing and design. now if you can still make enough tq to accomplish the task at a lower RPM, you may see...
