-do you have a thread diameter?
- if it's 5/8" F, should be 18 threads per inch, Grade 8 is 180 pounds minimum lubed threads...
-so 150 plus the additional turn to bend locks sounds very close (as per Rome)

Okay, I should have said also, there are 8 that are course thread and then fine threaded. The course threads are all in but not torqued

my book says 5/8" Coarse Thread, 11 threads per inch, Grade 8 Lubed is 170 pounds minimum
-so just a tad less

Thanks, we got one side done. It looks like for the other side of the steering clutch, we are going to need to drop the dozer, fire it up (I'm thinking of using the pony motor to turn the main motor) and put it in gear to turn the holes up to put the bolts in.. We put a 5 ft pipe wrench on the sprocket and can't get it to turn. We have two bolts in so far (the ones we can reach). Unless I'm missing something.

Make sure you release the other side steering clutch and the transmission is in neutral. The sprocket should turn fairly easily by hand Otherwise you could try putting a bottle jack under a sprocket tooth and moving it that way or a chain and a "come along" from the sprocket to a top roller or idler yoke. If it wont turn fairly easily then there is something else wrong.
You need to move it slowly to get the bolt to align up with the access hole and I would be doubtful if you could get it by using the pilot motor to turn it over.

Chain the blade up. Roll it with a jack on the track shoe. The limiting factor is it is much easier to keep going ahead by jacking at the sprocket if the blade is on. But if you have space to remove the blade space must not be a issue as that takes room too.

Hello Ray
My advise is based on the fact that he has already broken the track on the affected side but I guess sooner or later he is going to have to reassemble the track and frame.

Going to have to put it back together soon. There is no room to take the blade off. I knew there would be resistance, but I didn't think that much. Everything is in neutral and the levers are pulled back to the fuel tank. If I have the machine at a angle like so, Do I need to worry about the oil pickup in the pony motor or in the main engine from not sucking up and pumping oil? The photos are from when we started to tare into the machine a few months ago. I don't trust the harbor freight stand, so that will be replaced.

Some good oak railroad ties under the tractor would be a lot safer. Never trusted a jack stand with that kind of weight.
The supports in that photo look like and accident waiting to happen. Good Idea you have to get rid of the stands. Be safe!!

I'm thinking that the right hand side steering clutch is not releasing enough to turn by hand. Some of the plates are sticking making it hard to turn. Under load when running the machine it will release but not by turning it by hand.
I would put a jack on a sprocket tooth and try to turn it that way.
Oil pickup for the diesel will be fine at that angle. They are designed for extreme angles. The pilot motor should also be OK.
