They are necessary for preventing battery connection mistakes by poorly trained operators (not technicians - obviously we are expected to know MUCH better) - but if you are dealing with 88M's..... Battery change out is an operator level task just like changing a tire or a headlight bulb and the...

Just move the leads on the PPD output studs over to the matching input studs. That will take it out of the circuit so you can test. Then check connections and check the forward voltage drop of the diodes for each side. Should be about a 0.5v drop across each.

Ha! The trucks in service are typically NASTY after their first trip to the field and they will mostly stay that way for the duration of their play date with Uncle Sugar. The most that might happen is a shop vac gets run through it when the chunks of mud get too deep. It will take many trips...

I was at my buddies shop and didn't have my die grinders and accoutrements so I just dealt with it. Removing the bolt that you can get to and merely loosening the one you can only grab at a stupid angle with an open-end wrench worked for me as I was able to tilt the frame adapter and slide the...

You need a HEUI pump. *maybe* injectors but in my experience with three of these I haven't run across a badly contaminated injector yet. Get into CAT ET and go into the diagnostic tests and you can increase/decrease the HEUI actuation pressure. It will probably be jumping around at the lower...

There are some videos on changing a tire. Most don't show the best way, and few talk about the various different rim options, run flat and tire options, etc. And they aren't interactive much in terms of Q&A or hands on. Same with ECO hubs. Many of the videos are amateur or overlook details and...

Yeah the CTIS class is a must. That can also include using Dana Diagnostics to it's full potential, the pitfalls of 900 series controllers, Theory of operation and components. Adding additional program access to the truck's harness, etc. My truck would be there to show how that works. Someone...

If you're going to delete everything but the cab cylinder I would highly recommend getting the updated stronger cab cylinder for the add-on armor trucks since they are larger and you need the cab floor reinforcement kit that it comes with anyway since the cab floor is about as strong as wet...

I think a tire class is planned. Date codes checked at the gate? 😭

I've been asked to instruct and that sounds like a great time! I'll focus on A1 and A1R education. Definitely bringing diagnostic laptops and all the gear to do programming and re-rates, etc. Also discussed having an ECO hub install class - need someone with a truck and hubs that wants...

Correct. That is a big part of what it does.

Yeah looks like a good deal. (y)

I can cross the NIIN's over to additional commercial numbers in a bit. Have to get on another computer for that.

Close enough, yes.

Always use NEW valve stems and o-rings. This is the correct turret valve stem from Haltec: https://www.ebay.com/itm/234941162821 Don't skip those parts - the old one's will fail at about a 50% rate (higher for the o-rings) just out of spite and meanness (and age). The wheel half nuts (20...

Replace the diaphragms in all the wheel valves: https://www.pgttruckparts.com/599805-Eaton-Diaphragm-Seal-p/2264-599805.htm The cover botls break VERY EASILY. Heat and a punch to jar them loose and very gently work them back and forth and you might still break some. Rebuild the PCU...

Not saying you won't need a torch occasionally like for those huck bolts that are not accessible another way. If I can't get my angle grinder in there I'll switch up to a die grinder but if I'm hanging from my ankles with a snorkel on...... Well it is true that it can't be stuck if it's liquid...

Plasma is not the right answer for the huck bolts. Angle grinder and eye-pro. Go about halfway through them or a little more - right above the hex part and smack em sideways with a hammer. They are under tension so watch yourself and stay out of the line of fire. They tend to go flying and the...

The A1R paddle handles are *just* enough better that they don't entirely annoy me. What I have found through mostly error is that the handle itself isn't really the issue. You need new inner and outer latch mechanisms and NOT the Chinese copies everyone is selling. You want the original...

Eh. You should be laser focused on the reliability aspects before you start cutting and hacking. Find out what's working and what isn't and start fixing critical systems before you introduce more problems by deleting anything. You have years of work to get that truck to a place where you can...
