Yeah, it can pretty much communicate with every ECU on the A1 3126 varriant. With a prolink 9000 and applicable cartridge You will need a: prolink 9000 J38500-1 MPC J-38500-1500C For ABS ecu: Rockwell wabco abs/atc cartridge Can read codes and see outputs and do test For engine ECU: v1.11...

I never used a lab top but I use a prolink with a wabco cartridge.

I did that, I had to do a lot of measuring and moving the floor in and out. Even after it was done it still did not match up well. I ended up using all thread and plywood to hold the camper down, eventually I want to put in a steel plate mount with a spring in the middle to allow some movement.

I noticed before I changed to eco hubs, my truck would get up to temp pretty fast less than 5 min of driving at highway. Now my truck has a harder time getting up to 200 deg. I wonder if the heat production is from the transmission having to spool at such a high rpm. It would be nice to see a...

I have noticed that I do not see very many FMTV/6x6 reporting the same issues of, torque converter bolts, c6 thrust bearing, cracked blocks, driveshaft seperatation, and other catastrophic failure that are present on the lmtv/4x4. It may be causation/correlation theory but a possibility that...

I recently installed my ECO hubs. Install, he process was pretty straight forward, removed bevel gears, retorqued spindle nut, installed split collars, installed adapter plates, then installed the hubs. The part I spent a while was trimming the snap ring for the rear axle, I used a file and a...

I think WIX makes a filter kit for the Allison 3000 series. I want to say the filters are the same for a 2” sump. https://www.wixfilters.com/Lookup/PartDetails.aspx?Part=212315 Also you can just go to an Allison dealer and buy the filter kit, make sure you have your SN handy. I think the...

It is not in the SN range, I would pull your screen for the transfer case to see if there is more material.

what is the SN of the transmission. I think it was an aluminum cage on the C6 thrust bearing. It was changed to a steel then finally to a composite based on the service letter.

How does the hub nut lock without the gears? The torque is less then 20ft lbs Also the torque from the axle is transmitted through the hub splines. Looks like your design the torque is applied directly to the wheel hub gear carrier attach bolts. I would imagine the design may be strong enough...

bummer… still below the factory cruise control speed threshold.

How the the outer spindle bearing lubercated on the steer axle? Is it oil filled or grease packed?

That is frustrating, I had to replace my output speed sensor. The sensor just by itself was $1k, I had to drain the oil just to replace the sensor. For some reason the wires to the sensor start to get stretched then the connector dislodges. Mine had a contact that migrated from the weather pack...

It is just three. Is the pinion still engaged? Also the starter to bellhousing mating surface is potted with RTV.

Do you have the bussman PDP modules or the circuit board PDP. I smoked my PDP by reverse current my relays shorting the fly back diodes. The diodes become an alternate electrical path over currenting the traces burning the potting off then eventually destroying the trace.

I have that same alternator, mine has a ripple of about .5v at idle. Since it is not a hard failure the niehoff manual does not have a clear troubleshooting step. Did your voltage gauge have a flutter before the alternator died?

Do you know the hose manufacturer? They should have a minimum bend radius. looks like for a Parker 426 hose a -6 hose Bend radius is about 5”. Bend radius can be different depending on working pressure. What is the line pressure...

I have a 1078A1 3126, I like the ABS system, it works well and seems to keep the tyres from locking. I live in Alaska when I first got my truck from auction it had a few ABS issues, I had to readjust a wheel speed sensor and have my ABS ECU to reconfigure. After that it works great, I did a...

i use the UH2-5. It has a set screw to position the contacts, it is very nice when you are working with a bunch of different pin sizes, the problem is it is easy to not position them right and get a badcrimp.

I like the deutch connectors. The barrel crimps are superior in my option to the weather pack fold over tabs. The barrel 4 crimp is what is commonly used in aviation circular cannon plugs. The style crimp tool I use is the AF8 with the universal positioner.
