I have always found welding easier than precise bends. They tend to be a little tedious, as I have never really been set up to do it(typically have to build the bending jig for the press). For a one-off, i can cut, position and weld much faster..

Exactly!

well it is machining it... any knucklehead can remove metal:), the skill and "machining" comes in building the fixture to hold and move the cutter in the proper relationship to the workpiece. have learned some interesting ways to machine and fit, working with old slow speed diesels. All...

If i could build a reliable fixture for it…. I do have a large delta fixed belt-sander that could work:). Last head resurface i saw the machine was basically a large grinder wheel on rails…

For a one-off i would probably set up guides and draw-file it(dont have a mill or a local machine shop that i trust anymore), but a mill with enough travel could do it. Maybe with a light hone on a glass sheet to finish it off after the mill…

I just run my used motor and hydraulic oil thru it... Oh Wait, thats how I heat my shop:)

Well yes there is something for it to read, with control open the manifold that the sensor is connected to is open to the atmosphere. Thats its first check, can it see atmospheric pressure… If it cannot see that it will not proceed… have you had the PCU sensor out? They installed it pointing...

Yep, classic leak. Give a shot of air to open the valves then it dumps tire air trying to match the system pressure drop caused by the leak. Thats the same way the system deflates. They connect the system to a 6.5PSI relief valve(leak) that drops the truck side of the system down to around...

I think probaby the biggest issue we have is spinning the shafts way into the red zone. Longitudinal vibration is a characteristic of transitioning from one angle to another in a different plane with 4-point u-joints. The steeper the angle the worse it gets, hence the rpm vs angle limit chart...

Cool 2 batts is a good thing as it does not overload the puny 50/50 alts they chose to put in these things... Other than the computer interface on the A1/A1R trucks, the STE they chose for these vehicles does not appear to be al that useful, and most any competent tech will quickly outgrow...

Boost is usually dependent on load. Do a torque converter stall test. Second gear, stand on the brakes and add throttle. It should top out at the converter stall point ~ peak torque and full engine load. You don’t hold these too long as it really warms up the transmission fluid:) that should...

What were the conditions of that boost pressure video? Were you driving or in gear?

Yea the 2-3 shift is brutal in an empty truck. Getting rid of the 2:1 hubs also calms it down.

how much weight you got in it? any codes stored(press both arrows to enter diag mode use mode button to step thru the 5 memory locations). 3rd is where lockup is engaged, and with the 2:1 hubs, the trans has a real mechanical advantage so it satisfies lockup requirements almost immediately/in...

OK, so it is an A1 without the disconnect switches to the rear of the battery box? Green circuit card power panel in the pax dash? Not counting NATO plug wires, you probably have 4 large battery cables. Ground, 12 and 24v and a 24v line to the starter solenoid. Use an ohm meter and a long...

yea, unless you need to work on the latch:)

On my 1079 chassis, the tubular crossmember in the main frame looks to be far enough to the rear to clear the P6 clutch housing. At any rate, 8 Huck bolts and a hydraulic jack to spread the frame a hare and it could be slid to the rear.. It is the welded in Channel in the upper frame rail...

AKA: SAE or BSPP(british standard pipe parallel) type fittings that use a sealing Oring or sealing washer. There is usually a little step or bevel cut around the hole to contain the seal…

Yep, both pumps are in parallel. I did a system pressure test video and disconnected the output line on the hand pump and connected it to a pressure gauge. This showed me system pressure generated by the AOP while raising the cab and spare tire. thats why I suggested your hydraulic issues...

Or not. Don’t need a computer to troubleshoot mine if it has an issue:)
