Where did your truck come from? I am curious who may be responsible for such an oversight.

WOOF! That's not good. Looks like PVT Snuffy didn't pack it with grease. Now you get to pull them all off and check them all. That SUCKS.

When you reprogram the A1+ truck ECM to correct the speedo that same signal is used by the CTIS controller so it will go to over speed warning at the same ~65 mph that it always did. But you can pop into the Dana software and change the HWY over speed warning to whatever you want.

If you like, you can send me your ECM and I can flash it to 330 HP and make all the changes for pulse per mile and cruise enable, etc. Can also clone the ECM if you want to carry a spare. CAT generally can't or won't do that with a used ECM and new ones for the 3126 are crazy expensive from...

Broke a 1/2" extension doing mine. Breaker bar and a cheater pipe and some swearing. Fortunately my truck was a Kuwait/TX stationed truck and a 2008 so most of my problems are related to mud dobbers and the two dust bowls she lives in. Very little actual rust. I pity the guy that has an A0...

Might be ok for a short time. They have an expiration for good reasons. I wouldn't bother with them personally. That means they were made in 2009 most likely. Like old tires they will disintegrate surprisingly quickly once they start seeing use and flex, etc. Gotta love the surplus scalpers...

How old are they? They have a hard and fast shelf life due to their construction. They will turn soft and gummy. If you can press your fingernail into the material and it leaves a permanent imprint they are trash. I see "new old stock" one's being sold that are absolutely trash. And others...

You need an additional set of the cab support bushings - the A1R stack up uses the same bushings as the front of the cab. I had new one's made by one of the original manufacturers. I have sets for sale. $175 shipped per set. A1R needs two sets and you'll end up with one spare thick bushing. With...

The manual switch doesn't function any different than the disconnect relay. At least in the stock configuration the LBCD is designed to allow the batteries to be disconnected from the charging circuit and *not* cause a spike that nukes the electronics from orbit. Of course if you have deleted...

The ECM will throw a silent code for that sensor with the 330 map. Not sure how necessary it actually is - probably just some kind of minor altitude fuel trim for emissions. I've never had anyone say they noticed a difference with or without it. As you go up in power, more fuel is required and...

Your disconnect relay or it's interconnecting wirings is probably shot. It's actually TWO relays in one unit - one for 12 and one for 24. And they are "latching" relays so when they change state they stay that way without power applied. Sounds like your 12v relay or the control wires to it have...

Is your cover missing the metal data plate?

4 AWG is roughly good for 75 amps. Could be higher or lower depending on rating but being mil spec it's probably 90C rated copper which is actually like 95 amp rated. If you want to be safe then re-purpose the 12v lead to the panel for one of the Victrons and just hook it to 24v instead.

The pressure spec doesn't tell the entire story since it doesn't say if that's gauge pressure or absolute pressure - referenced to sea level or referenced to outer space...... but seems like it's certainly gauge pressure given the max reading. CAT changes part numbers like most people change...

The Allison transmission computer doesn't know or care what your over the road speed is. There is no programming required for gear ratio or tire size changes. The speedo is controlled by the engine computer not the transmission computer. It's going to downshift when you floor it if you are...

Here's what the TM shows - both of the sensors are referred to as " SENSOR,MANIFOLD ABS" :cautious: 🤷‍♂️ Definitely would be good to figure out the exact part number for you 3126b guys. I just tell customers to go to CAT and give them a 330 HP serial number off an engine sticker from a...

Yeah the TM is not super clear on which one is which. Ultimately it's best to order it from CAT with the serial number of a 330 HP engine, etc.

TM shows it as a 194-6723

True. Soon to be in the minority though since all trucks from late '99 on are fully setup for J1939/J1708 coms. After 1999 all trucks have busses. And your WTEC II has some kind of live data though I'm not sure if it's J1708 compatible..... the diagrams just say serial communication and I...

It's a piggyback - it sits between the engine sensors and the ECM. It tells the ECM that the fuel pressure is lower than it actually is, so the ECM will command a higher fuel pressure thinking it's too low. This creates additional wear and tear on the fuel system that is now running a higher...
