    Default M123

    The M123 at the Museum was moved a while ago from it's spot for the RC tank club meet that is held monthly. When moving it, it died...I didn't know that. I was tasked to get it going to move it out of the lane. Did a filter service, there is alot of algae in the tanks, fuel is dark. When I pulled the filters, the screen filter was full of black algae and the can filters had alot of crap in the bottom, rust included. I cleaned the cans, changed the filters out and drained the rt tank. I decided to temporarily install a Racor before the 3 stage filters to TRY and keep the junk in the tank from getting into the tri filter set up, THAT is a pizz poor design! Any who, It was being a PITA to get go juice to the pump. Decided to go directly to the pump from a jerry can. No suckie fuel. I think the pump failed, that's why it died. I pulled the pump, the throttle shaft was locked up, so my assumption of water in the fuel was correct, unfortunately. The shop called today, it is done, I have known these guys a LONG time, it was upwards of 500 bucks to fix it, I HOPE the injectors are OK, we will find out next Wednesday.



    I'll have a vid when it runs!

    I went through this nut roll with a Bn full of 15 and 30 KW gen sets. About 40 sets. It was training equipment. No one took care of it. When a unit, (Patriot) tried to do a week field exercise. No gen set ran more then 4-5 hours without failure, if that long. The only way to cure the problem was a stand down. Four days, an entire Bn in the middle of a training cycle. EVERY gen set had to have its tank pulled, and steam cleaned.The entire fuel system had to be removed and cleaned, up to the IP. All filters and strainer had to be changed. And then all put back together. Strangely enough, all these gen sets ran without failure for the rest of my time in Bliss. The next failure was almost 45 days later, when an alternator belt blew. Go figure.

    This is just what you should do. One after another. If I was living someplace close, I would love to do this to each one of the vehicles there.

    Pump is done, but that happened after I left for the day. I was out in the south 40 and found a nice pump, 110AC and a Luberfiner filter set up we can make into a scrubber. That is another project, probably for a rainy day.

    OK, an update, Put the pump back on, sucked fuel like it should. Fired and ran OK. Smokes, it did last time I saw it run. Moved it into the back shop. and gave it a little love. Permanently installed a Racor pre filter to prevent the tri filter set up from getting full of crap. The lights didn't work, troubleshot that and found the turn signal lever assy the cause of that, replaced some burned out bulbs, fixed some bad connections on the headlights. Figured out why the air tank over pressure valve was popping off, there is a valve on the firewall, just like the one on a deuce on the passenger side inside firewall, on the drivers side by the steering column, that was off. Well, that sends a signal to the governor that the tank is at pressure so the compressor unloads. If it's off, it won't unload! I like easy! There was a shield over the pintle hitch that was remover for some reason, and sitting on the back of the truck. Installed that. The brake pedal felt funny, so I checked the adjustment, the slack adjusters were almost 2 full turns out of adjustment . Fixed the e-brake, lubed some zerks. I was going to put a hard top on it, there are a few in the back 40, but decided to not do that because they didn't come with hard tops. Also found no glass in the passenger side door. Went to a donor M series truck, again, in the back 40, and got a good glass, installed it, cleaned the cab, drove it ariund the circle a few times to get the juices all hot and juicy, then parked it in the middle of tank row for a bit.

    I tell you what, this thing is freekin' BIG!

    Oh my...look at all that workspace. I'm positively green. Where is all that bright light coming from? We don't have that here in Maryland.

    That is a thing of beauty! I found one when perusing Facebook Marketplace yesterday. They want $15k for it. Would love to own one, but no place to put it right now!

    Do the steering brakes still function?
