Here is the latest update...
It is a bad accumulator. It needs to be rebuilt by Tazwell. So it, and the pressure cylinder (do not know what the name of it is at the moment) are going in to the shop. This will not happen until I head back to LA (maybe a couple of weeks) so I am going to just have to rough it.
Our tests revealed pump was good, bypass valve was working, but that the accumulator needed to get warm before it would operate (it is cold in the AM and maybe that is why I did not notice this until now as it is only now starting to get cold).
They are going to recharge the pressure cylinder, and then rebuild the accumulator.
JJ. I think this might help. There is a spring valve on the accumulator. Something that hangs off the side. It is bad I think. The pump is creating pressure, and the brakes are getting pressure. Just the steering / lift tilt is not and needs a little love to get going.
The PDF is not my PT. There are some differences...
One of my side plans is to replace a few more hoses (the ones coming off the accumulator) in my ever increasing process of updating hoses.
As for brakes, bob had your answer.
I do have some photos, will get those up tonight.

David,
Yep, you are probably right. They would be stupid not to read this forum. I think they do read the data, but don't know what to do about it. You would think any company worth a crap would give better service to the people that helps keep them in business. With all the data we have come up with over many years, you would think they would almost have a perfect machine with the best manual available, but no they are still trucking along with that old mentality. I wonder if any of the folks at PT even own a PT? I am betting that they don't. They probably drive a John Deere or a Kubota. I feel really bad for the people that don't know enough about the PT, hoping that PT will keep them out of trouble, and especially the people that use their machine in a business. That would give me cause to get something that is supported and has manuals.
I think the PT is a good machine, but could be a better machine, but do you think we will ever see anyone brag about the manuals both parts and service. I believe that someone even said he had a very good set of shop manuals for their PT's. but don't remember who. We can make you a PT, but no manuals, the Xerox is broke. You have to take our word about it.

Terry told me he has a PT. I don't remember which model it is.

It's just lawyers. They will not kill me but they might make my 401 K worth a lot less. Oh, they already did that.

Carl, Did you send your parts back to PT to rebuild, or to a local hydraulic shop?

Carl, On the accumulator thing, Accumulators will work in almost any condition, and don't have to get warm to work. That accumulator is simply a steel vessel with a spring and a bladder or piston. If it comes up to pressure with the pump running, and it holds, the accumulator is good. If you can pump up the accumulator and it holds it is good. The setup on the output of the accumulator is what keeps the fluid under pressure. It is probably something like a shuttle valve which keeps the fluid contained until something triggers the valve. What that has to do with the steering, is beyond me until I can see a schematic of the system as installed in your machine. If you sent it back to PT, make then send you a schematic for that system reiterating the fact that all of us would desire a decent manual. ****, just tell; them you would like to make of movie of their PT program, and especially their MANUAL producing factory.

I am not sending said offending device back until either the weather turns bad or I go out on location to shoot. If it take a couple of minutes to work I can live with that, as long as it does not abandon me at the bottom of a hill. Will keep you all posted on this issue.
