He mentioned it was a "900 series" (M939) truck. They are 100% air brakes any way you look at it. Any of the older 5-tons would be hyd brakes with air-assist. I don't think you'd need a air brake endorsement on a older 5-ton. Most states do tie the CDL requirements to GVWR. My uncle got a...

Let me know when you get around to fooling with it. I'm curious as to what the problem is. It does in fact blow oil out both exhaust and smokes terribly. Runs like a top other than that.

I do have a t-case PTO that will fit the M939 trucks. PM me if interested. I'm using a t-case PTO to run the dump on my deuce. Pumps can be had fairly cheap (less than $300) from places like Northern Tool. Driveline parts can be had at NAPA or Tractor Supply. I did have to make a flange to...

You are correct. A guy posted the question and people gave their opinions (including me). It's up to the individual reading the thread and TM and decide on their own what to do. I don't see it as a safety issue (endangering others) so start out in 4th if you feel you need to. :)

Just about any gear oil will work. I also run 100% corn head grease in mine. It's not full to the top but I put more in than if it had gear oil in it.

There are some exceptions. In TN if it has farm tags and operated within 150 miles from home, a CDL is not needed.

Yea, I know what it is. Not a real good practice though. I suspect you could overspeed the deuce drivetrain real easy using Georgia overdrive.

I do float the gears on non-synchronized transmissions. It's hard on the syncros on synchronized transmissions though. On the deuce I use the clutch.

That's a very rare engine. :wink:

I reality you can fudge on the start up and shut down times when not running it hard or the engine is still warm when started. By the time you pull into the parking lot and find a parking spot your turbo should be cool enough to go ahead and shut down. As long as you're not it the store for a...

Sure you can start out in second. Your clutch won't last as long though. Guess it depends on how well you like changing clutches. There are several small things you can do to insure your clutch has a long happy life. Starting out in first is one of them. I do sometimes start in second when...

The main reason I wouldn't want to leave it running in that situation is because somebody might decide to jump in and take it for a spin. :grin:

While most people call them "freeze plugs" that's not what they are actually made for. They are simply plugs to seal the holes left from the casting process. People call them freeze plugs because they can pop out and save your engine if it freezes. You're not out of the woods yet though. Even...

Yes. It doesn't have anything to do with you engine running away though.

A short to ground in the wire will cause the gauge to peg.

I'm not too worried about it on my deuce. It's not the best way but usually if it does run away and you can get to the side of the road, you can put it in high gear while standing on the brake to shut it down. I've been around a bunch of diesels in my life. I've only seen two of them run away...

Many things can cause a runaway. Turbo seals and IP malfunction are the main ones. It can even be caused by driving near a flammable gas leak such as natural gas. Except for 2 cycle Detroits, runaways are fairly uncommon. The main problems with 2 cycle Detroits are blower seals and the governor...

They gives a new meaning to the name "screaming jimmy". :) I thought the compressor wheel was going to eat his fingers when he tried to smother it.

I've always given them a measurement from center of yoke to center of yoke. The yokes will have to be disassembled for them to machine it. What I'd do is disassemble the yokes, temporally bolt the flanges back into place, and get a overall measurement from center of yoke to center of yoke. That...

I've bought and sold a few hardtops. They bring good money but they are a pain to deal with. Too big to ship reasonably and they take up a lot of room hauling them to rallies and such. Personally, I'd want to be in around $400. Even selling them for $800 and hauling them around to rallies, you...
