Yeah our state dictator has decided to put out another mask mandate with no end date expected and has started mandating vaccinations for agencies and businesses but for some reason has given exemptions to the legislative and judicial branches, evidently it’s only safe for the lower people. Not...

I’ve been enjoying mine taking it to the local tractor show during the military appreciation weekend section of it. My son drove it in the parade portion of it, I met some great guys that are part of the local chapter of military vehicle collectors. Mainly they’re into the ww2 and Vietnam era...

With the time it takes to build up the air brake pressure, move the other rigs out of the way to get it pulled out of its parking spot it usually gets a warm up period before I take it out. I had asked the crew at Peterson cat to do a filter and fluid change on the transmission but they just...

Well after some looking at the cables, linkages, and whatnot I didn't see anything that stood out as obvious to being the culprit for the hard downshift into first. I even had the local Peterson cat heavy equipment repair shop take a look at it. They said with the exception of maybe one of the...

I see the ad for the Burma has been taken down by owner. Did you happen to be the one to purchase it?

The past couple months since we got through the freak ice storm and have started to get into summer I have been working the 5 ton like a dog. Lol. I actually doubt the 5 ton even notices that its being loaded over. But what have I done with my 5 ton, hauling multiple over the cab loads of...

I'm not sure if this is the appropriate spot for this, if not please move to the right place. Spotted on the local craigslist in Tualatin Oregon an ad for a 1943 Burma jeep project. Very cool machine I just have more projects going than I can get to. Thought I would pass it on to the next...

Checking out Ccc cable, I see they have modulator cables for the mt600, I'm thinking that the transmission I have is the mt654? As I'm not familiar with allison transmissions. I can be completely wrong, does the mt600 cable modulator they have work on mine or do I need one specific to the mt654...

So then getting the replacement Ccc cable should help? Or would I need to replace the spring at the cable base as well if that's possible.

Okay, I'll use ATF in it when I do the change. And go with a Ccc cable, but when I say it hard shifts, it's more like a slam. I have thought that something is going to break or split, as it's just started to happen unlike any downshift before. I half expected to see the tailshaft come off the...

Air pressure always remains fairly consistent at around 110-120psi. I think I may have misdiagnosed what is going on. As today I drove it a few miles down the road to get a load of dirt and when I pulled into the quarry yard I wasn't even touching the brake pedal and noticed when the...

I am not hearing the two clicks at all. But will definitely check again to verify that. The truck has only sat for a couple weeks of no use, and I have been driving it several times before letting it sit for those two weeks. I'll get a temp gun today and get a reading on it to see which one is...

Thank you very much for the info, I will definitely check it out. I am sure there is a strong possibility that I could have blown the fuse when I shut it down incorrectly. At least I am hoping that is the case.

I noticed the abs dash light that's normally on is not lit up anymore. The brakes are grabbing really hard at the last part of braking. Any thoughts on how to correct this or get the pcb box to communicate with the system? Any thoughts or advice would be greatly appreciated. Thanks.

Finally got the m939 running and driving again, then today when we made a run to the recycling center the truck started a new issue. When slowing down while braking the truck feels like it has the rear brakes are coming on strong and grabbing. It only does it the last part of braking when coming...

Well finally it lives again. Broke down and just ordered a new pcb box from boyce equipment. Showed up in two days, swapped it in and instantly had power to the gauges with the battery switch on and started it right up. Still going to rebuild the old pcb and the used take off one that was no...

When I was bypassing the solenoids I had my son in the cab and asked him if it showed anything lighting up or operating on the gauges. His response was no, I didn't look myself. I'll have to check the combined output of the batteries again to see what they are, I'm guessing the procedure for...

The truck was turned off when I operated the battery switch and the pcb harness was reinstalled.

Okay, so I used a jumper wire on the pcb harness. Truck turns over and starts. After that I turned on the battery switch, no dash gauge lights, only when I operate the light switches do I get lights, which I know are on a separate circuit. Plugged in the pcb harness and smacked the box with a...
