Welcome aboard!

Do you have your Freezolium to lubricate the bearings as the tag indicates?

Chinese knife switch on Flee-Bay. 200 amp, 4 pole. $65.00. Obviously not snap lock. Absolutely must be enclosed. I'm thinking that the enclosure on an inside application is to contain any arching. If I configure so there is no wire bends inside the enclosure would a much smaller enclosure be...

Thank you so much for your reply. We got a great bunch of guys here. Remember " Everybody doesn't know something at sometime" :-). NHC250 compressor head rebuild thread w/pics cumming soon.

OK so I checked the coolant level after the truck has been sitting over 5 days. The expansion tank was definitely pressurized and empty. re-filled to proper level and started the engine. As the engine ran the coolant level came up and over flowed with the cap off. Engine never reached operating...

Seal was very very tight. Took numerous hits with the slide hammer to get the old one out. Using the 2" socket to get the new one in was not my first attempt it was like attempt number three or four. Trying different methods. Was there a lip in the housing behind the seal preventing the seal...

Disclaimer; not a liable prone how to, Just sharing my experience. The radiator drain petcock is right above the glad hand, use a cut section of garden hose to direct the draining coolant into the bucket. (B.T.W. petcock end is hard to find in the dirt). Used a 2" 3/4 drive socket for an...

Changed thermostat and cap. runs only a little bit cooler. The fan clutch engages a little bit less. Actually runs at exactly what the thermostat and fan clutch are rated for. When I pored the coolant back in it ended up right at the proper fill point. I carefully monitored the temp, fan clutch...

Excellent!! P.S. Exact likeness of myself

I going to be hooking up my MEP-003A as stand-by and to run the three phase stuff that cane with the M944A1. Transfer switches cost over $300.00 and the enclosres are huge. Why is that? I can buy a Chinese double pole single throw knife switch for under a hundred dollars. What kind of enclosure...

Brilliant!!! On civi vehicles you would leak gear oil. but our MV's have an isolation seal to the outer axle bearings. The outer axle bearings are greased.

As a manufacturing engineer one of my jobs was to gather the facts so management could make an informed decision. 96% was about the money 4% other (re-election for example). I believe our letters to the legislators would have more impact if we included the facts. We might be able to assemble the...

How about: Thank you for spending months and months gathering valuable official Unimog Shop manuals, over coming numerous failed data transmissions and spending hours uploading over 5 gigabits of data. I know you have other things to do . I Know Steel soldiers is not your main focus in life and...

Actually Patracy did all the work. So when you benefit from them please keep a warm thought for him.

How in the world did you figure that out? That ties in to my air bubble questions. When I took the cap off it was like it was burping. Putting the thermostat and cap in today. Taking a test drive going down main Street with her dressed out for the fourth. The level was per the...

I hate you. :-x, Just kidding.

M944A1 w/NHC250, All of a sudden the coolant tank level is too high. Just enough for the overflow to drip on a race track with engine shut off. With the engine cold I took the cap off and coolant came out. Any chance of some sort of air bubble? Transmission cooler leaking? Bad thermostat? It has...

Look all over the engine. where might I find the tag on a M944A1 w/NHC250.

Trying to get a commitment from Jim and Donnie. They both keep tremendous work hours. At this point they are a solid MAYBE:-?.
