Is there a main valve to turn air off to the CTIS system on a M923A2 truck. I stopped the leak and the pressure does go up to 90 psi and just stops. But not leaks. I am thinking the air governer needs to be adjusted as it is new (replaced some 1 year ago).

Sorry about the late response. I use an air compressor to pressurize the trucks air system. At 65/70 PSI, I discovered a leak under the radiator. Probing around, I found a broken hose leaking air. I am in the process of tracing it. A visual inspection of the airline break, it does look like...

It is a M923A21. Had the Cummings 8.3 engine. I had the CTIS removed. I am suspecting we may have damaged this airline when we pulled and had the engine overhauled back in 2022. I use this truck maybe twice a year. Ill check tonight on the airline placements. Thanks!

I have been working on and off with an air problem on my M923A2. My truck will not go past 60 PSI on idle and 90 PSI when I have the RPMs at 1800. When the truck is under power (on the road), it will reach 120 PSI. I have replaced the governor, air compressor and air dryer – same issue. I...

Found a new fan clutch for $1100. Now to head back to Death Valley and work on the truck in +95F temps. Truck will have a new radiator, new fan impeller and new fan clutch. Hopefully this will all be behind me. Do plan to switch over to an aluminum radiator here shortly.

Yeah, figured as much. Once I discovered the bent shaft, I knew it was over and a new one was in order. I pm the individual here who said he had a few but no response yet. Yes, ordered a new fan impeller. Other was damaged.

Ok. Maybe he/she will shine in and let me know. Thanks!! Sent from my SM-G900V using Tapatalk

Okay, I'll look for one. I've all ready order another oem radiator. Sent from my SM-G900V using Tapatalk

Not sure what you mean by fan number. I did call kit masters and they could not help with any of the numbers I provided them from the TM's. They sent me a picture of what "they" thought, but it was not the right kit.

I priced out an aluminum radiator and the cost was close to $1700. Checked with two radiator shops. Not sure how you came to $700, but very interested.GIJOEL

Pictures of the parts damaged. Major gouging.

Had a catastrophic failure with the air clutch. The failure caused the radiator fan impeller to break loose and cut deep into my radiator. Regrettably, I was 100 miles away from any major help. In order to get it to a safe location, I manage to pinch and fold the fins/ribs of the radiator as...

Will that work on the M923A2 engine? Anyways, I can purchase a 400 AMP 12/24VDC alternator. What would happen if I replaced the one that fired with one of these? Could I cook my batteries?

We ran a new wire from alternator to isolator. So it cant be a short.

I am at my wits end... I have fried two alternators and cant figure out way. I have an original 60AMP M923A2 alternator installed in truck. From this, I took the B+ lead from alternator directly to a battery isolator which goes to two different battery banks. First battery bank is composed...

Thanks! That is what we thought. I may upgrade to a 100AMP alternator. Circuit breaks will be installed all around... I learned that a long time ago!

I may have cause some confusion with my original post. I plan to run two battery banks. One will be primary for the truck and the secondary will be for the camper. I purchase the battery isolator as to charge the primary bank first and the camper bank secondary. Since I am using the 24V...

I'm in installing a battery isolator on an M923/A2 truck. Reviewing the manuals, we "think" we have it figured out... but because we have some doubt, I decided to confirm it here. Can someone please provide instructions on what wire lead, from alternator, is to be removed and hooked up to...
