hello
my friend and i have been working on an SC case for a while now and are still having the same problems. The tractor will start and run, but will slow down and then lock up. We can leave it sit, and then it will start up again and do the same thing. We have checked the oil pump out, and it is working. The tractor appears to have been rebuilt by the previous owner. We cant figure out what it is. Any help is appreitated. Thanks

We Are Learning From One another Here .the Only foolish Question Is from those who refuse to ask questions ...

I second pulling the pan and checking everything. It sounds like something is getting warm and expanding then locking up.

We have pulled the pan and had everything apart. When we use the hand crank to turn it over, there is a definate hard spot where we have to really pull on the crank to get it to turn. The hard spot is still there with the pistons out of the block, the mains loosened up, all the pushrods pulled and the head off. So basically the only things left turning is the crank and the cam. I dont get it.

Could there be something caught between two gear teeth? Let us know if you are able to figure it out.
