no matter what, you will be at least pulling the head! what drives the
waterpump. is it gear drive like a 3306, or is it belt driven. no matter
how it drives with no fan it got hot! you most likely be doing a major
on this engine if it stuck due to water or antifreeze in a cylinder from
a cracked head.

ujoint, The engine was not run without the fan, the fan was removed because the fan shaft got twisted. The fan shaft is what I am not understanding because it sure looked to me yesterday like the fan would bolt right on to the pulley.

Old magnet you are following me precisly I don't understand either because that is exactly what I was thinking when I was looking at it. But the guy is persistent that there is a shaft for the fan and it got twisted or bent.

Now this morning I was laying there thinking about it and I think he may be right there may be a shaft that bolts to the front of the pulley to extend the fan out closer to the radiator and maybe also to give clearance for the hard nose cross shaft. does anyone have a book on it to give me an idea if that is right?

It is a belt driven water pump ujoint sorry I missed that question.

There is a fan belt adjuster involved...I wonder if the owner is referring to that.
It is possible to bend the bracket.

Here's one of several water pump variations
and
The adjuster.

No extension involved.

Ok, I went back out there today for a bit to try to get that thing going. I pulled all but one injector and I broke my breaker bar on it and didn't have another way to pull it so I pulled the glow plug to relieve any fluid lock possibilities. there was no fluid in the cylinders but the injectors were wet with diesel fuel which suprised me a little. I filled the cylinders with as much diesel fuel as I had with me. I pulled the starter to get to the fly wheel to try to move it I can only move it about a quarter inch in either direction I do know that one piston is moving because it pushed diesel feul out the pre cup (just spurts) that is the only one that did it so I am not sure what is going on there.

So I called the guy and keep in mind that he has no reason to lie to me and I believe him when he says that when they first hooked the battery up that the engine turned over one quarter of a turn and then stopped dea and would not move again. he did say they had four batteries hooked up two set in parellel and the sets hooked up in series (24 volt starter) I don't know if that gave him more cranking amps and it pulled a piston apart or what.

Do you guys have any thoughts on that?

old magnet I also ask the guy if he could talk to has step dad and find out exactly what it was that was bent or twisted so hopefully I can get some better info.
thanks all...

I do have one more question. what is a d6b running with a really good bottom worth. the reason I am asking I think I can get about 1800-2000 from a local equipment scrap yard and I don't know if this is even worth fixin. if I can only get 2500 from it then I will just let them have it and be done with it. if it is worth more then I will give it a good effort to get it running.

The first thing that comes to mind is rusted up cylinders. How long has this thing been setting? The early stages of rust will sometimes let pistons move but then they lock up....soaking may get recovery, may not.

As far as value, it has to run to be worth anything more than scrap. Any additional value would come from condition of undercarriage (real measurement), blade, hydraulics etc. At best they were not one of Cat's finest with the D333 prone to overheating, cracked heads and spun main and/or rod bearings. Might be able to achieve $5k -6K if all is good depending on value and demand in your area. Segmented sprockets would be a bonus.

No, your not likely to tear up a piston with direct start....but you can break rings and bugger up ring lands in rusted cylinders if you force it.

Unless it comes free easily your looking at removing the head.

Hi, Crazylegs.
If you decide to go ahead with this, as Ujoint said and Old Magnet, you will at least need to lift the head and have a look in there to see what the problem really is. I am NOT a diesel mechanic but I would not bet that it is not diesel fuel causing a lock either. A leaking injector, a full tank of fuel and standing for a while might leave enough fuel in a cylinder to cause that.

What does concern me a little is when you say that you can only move the flywheel about a 1/4" EITHER way. I can't see any form of hydraulic lock, either water or fuel, causing that. What has happened to take it from moving about 1/4 of a turn to moving about a 1/4"?

I think O.M.'s assessment of the value is pretty spot on. You may make a bit out of it selling parts from it, depending on the condition of said parts.

Don't give up just yet. Keep looking for answers.

one thing is for certain deas I am persitent probably to a fault. I don't like giving up if there is a shimmer of hope. It is definitly not a hydraulic lock I had all the cylinders open I am thinking now that it is rust and I am trying to round up some help for monday to go pull the head off how much do you think that thing weighs anyway surly not more than 200lbs.? If I do get the head off on Monday what would you guys recommend as the first course of action to try to get it broke loose? A mallet and wooden block to jar them loose and hone the cylinders if it works?

Just out of curiosity is there anything else that might freeze up that might cause this I know the Generator is froze up but the fan belt is off so that is not holding this it is a gear driven hydraulic pump are they pretty reliable. just wondering (thinking outside the box)

om the best they could come up with is it set for about nine years You couldn't tell it by looking at the thing it looks really good.
where can I find the measurements for the track so I can see exactly what kind of shape it is in?
