Any pictures/videos from this event?

I so wish I could be there but, sadly, I will be in San Diego. What time will you guys be meeting up and where?

I have not. Are those located on the tanks?

Thanks for the feedback. I knew it had to be somewhere up there. I am chasing a constantly buzzing low air warning indicator. I have checked all other components but the Failsafe warning Control Module and accompanying wires. I will do so this weekend and report my results. Thank you @Artisan...

I know this is a stupid question but I can't seem to locate the controller in the truck or in the TM's. Where is it?

A number of weeks ago I had a thread about an air leak on my 1987 M923A2 that was shut down. This post is addressing the points discussed from that thread. The symptom was a hissing sound coming from the intake stack and rapid air loss of the secondary air system. After much searching around...

I would love to make it, but will be in Zion tent camping!

Hello, Driving my truck yesterday and had the fan coming on and off in a very normal manner. I parked it and shut the engine off,after a few minutes I hear the prominent hissing of leaking air. Its coming from the engine compartment. I pop the hood and start looking and come across the fan...

High beams work. Time for a new bulb. Thanks.

I recently purchased a truck rebuilt by RRAD. I contacted RRAD to get info on where my truck came from and any other info on what was done to it. They couldnt tell me where it was stationed but they did have the rebuild records for my truck. They stripped the entire truck to the frame and...

[PS: Come and visit us in Nevada City Montana and take a ride. It is one heck of a trip, 14 miles, about 6 of which will feel like they are straight up. 8500 feet in elevation right to the foot of a mountain and through more than a dozen mines and 5 old towns. I can no longer offer camping at...

I am also having a headlight issue. Only one of my headlights works on low beam. Both work on high beam. I purchased a used replacement lamp but still have the same issue. I used a test light to ensure I am getting power all the way to the connections, and I am. Could it be possible I got...

FWIW, My local Allison service center advised that 15-40 motor oil would be suitable for my SoCal climate.

Found and read the TM. Looks pretty simple. Ill adjust and report my findings. Thanks

I have not looked but Im assuming there is a process in the TM for adjusting this.

Thank you @Artisan. I thought that sounded like a bit of a stretch.

I believe the shift would be considered harsh by anyones standard. It really kicks good when going from first to second. The whole truck shutters. The downshifts have not been nearly as harsh as I expected from talking to other 939 owners. Im wondering if running a higher viscosity oil in the...

Couple of Beauty shots for you guys!!

Hello All, My truck shift quite harshly from 1st to 2nd when trans is up to temp. Shifts smooth when cold and gets harsher as it warms up. Any ideas for smoothing out the shift? Its running motor oil. Thanks.

After performing some troubleshooting this weekend I was able to isolate the issue is with the treadle valve. When the system is pressurized there is a steady flow of air coming through the secondary side of the valve and exhausting through the line going straight to the stack. I will order a...
