Had this problem for a while now, with two different pumps. When lowering the cab (allowing gravity to do it slowly - no pumping on the way down) I get hydraulic fluid pushing out the vent plug. It will do this on successive raise/lower cycles until it pushes out enough I can't even raise the...

I wouldn't mind changing out mine for some of those 5 point belt style, see some seats on govplanet lately. This is the style, but these look like the middle seat.

Found a spare, unused ECM. Got it reprogrammed for 370 horsepower. Going to keep my original one stock horsepower and use it as a spare I think. Wasn't the easiest process but eventually got it done. Haven't tested it in the truck yet.

Looked around a bit but seeing so much different info and a lot of it is for prior than A1R trucks. Best I can tell, I only need the alternator for the upgrade as I have the single belt, supposedly correct alternator bracket? Plan is to power a mini split and use for both cab and habitat...

First winter with an A1R and also a diesel. Started it today in 10f and it was not very happy. Had to crank several times(was letting off same as I would in warm temps- when I hear it ignite). Then held starter for a few seconds after catching to keep it running since previous method didn't...

Anyone have any tips on removing these? Wondering if special press tool is needed, or if the taper is big enough they can just be tapped out fairly easily?

I've seen a people do this a little but not too much quantitative info. Can the manual pump supply enough fluid with its tiny reservoir for both the cab raise and tire lower? Just from glancing at the volume, seems like it would run out of fluid with just one of these operations-if it could...

It got down to about 30f today (yay snow?) and since I got the tail lights reconnected I took the truck for a drive (first real test with Eco hubs too). The truck didn't turn on the grid heater before startup (for the past month it has-40-50 deg). I tried starting and it cranked up better than...

Searched all the threads I can find on this topic but couldn't find any part numbers for replacing these? Seems the standard is to find a NOS entire link but was hoping someone had found civilian replacement part #? I do have the one with replaceable joints on both ends.

Well my title and registration finally came through after two nail-biting months of waiting on the WI DMV. Did lots of research reading WI laws but seems some people still have problems registering and titling so it was a big unknown. For the past few months I've been fixing things as I had...

Let off the throttle and the light went off. Since these motors are so pricey I decided to get a reader, bought a surplus ICE test kit. After fighting with scratched DVDs and old computer hardware I got : 102-07 "Boost Pressure Sensor Not Responding" A quick search indicated a boost pressure...

I can talk to engine ecm, transmission tcu, Spicer CTIS. Wabco ABS seems to be a little different? Using Dearborn 3+ and can seem to connect over J1708 but wabco software doesn't really show much data, most fields are blank. J1939 doesn't seem to work at all. This is through the port to the...

My truck didn't come with a CTIS controller but I found a "probably broken-untested". Plugging it in and it seems to work as it should, electrically at least. I had a missing quick release valve for the front axle, then both hub breathers were disconnected, then found a hub seal leak, then the...

When using the manual pump for any operation, it will run empty and not pump any longer. Thinking the fluid might be a little low, I refilled the manual pump tank, but I'm noticing it's pumping fluid into the air over oil pump reservoir, this caused it to overflow. Guessing is a check valve...

Solenoid/valve is seized. Before trying to source a new one I figure I'll try and rebuild. I was able to get the solenoid off the bottom but it appears the valving may come apart. Curious if anyone has any experience with these? I tried a pipe wrench and no joy there, but it may have a ton of...

Noticed a rear tire was down on pressure a bit so refilled to 80psi. Also replaced the quick release valve near the muffler as it was missing. Then after a drive, gear oil sprayed out of the discharge from the quick release valve on the forward rear axle(connected to the tire that was low)...

Wind was pushing them back, had to have my kids constantly fix them. Looked around the hose and found some scraps that I mounted with the unused screw holes on the doors. Clamps are just standard cable guides (silicone) and the other parts are aluminum pieces I had laying around from other...

Seems this had to be a modification? Wiring diagram for A1R I don't see mention of a 100amp option, only the 260. It has all the other A1R stuff (grab handles, insulation, WTEC IV, etc).

Can't find anything on here of the TMs about this (only the part breakdown) Seems to have a fill plug so I'm guessing oil filled till comes out the hole? Any other ideas?

So I bought the truck and had some really strange wires going to the taillights, one for right turn, one for reverse. See the wire and black wires here: (also notice the black wire seems to be holding the trans cooler line :oops: The blue circle is where the trans line was rubbing on the bolt...
