Re: Used PT\'s
Keep and eye on www.power-trac.com Click on the title (Used PTs). There isn't a 425 there now but in the past and most likely in the future there will be one. If you don't get in a hurry and jump when the chance arrives you get yourself a deal.
The one on the PT422 built in 2000 is 1 and 13/16 inches. I suggest you call Terry to make sure. This is one expensive wrench. I paid $125 dollars at NAPA. I suggest you try other places. Clint Blake found two versions at Hanover Tools for a lot less.
You might try a local farmers Co-Op. If you have one close.
They have some large wrenches in the one close to me, by the nuts and bolts. I have never looked at the sizes but they are BIG, seems the prices were $85 or $90 for some of them. I go there to get Grade 8 bolts, they are cheaper than the hardware store, by about 25-30%.
When I took the class at PT they told me to check the torque often (every 8 hours is what my memory says). I asked how much torque and they said, "Everything you got". I have had a little movement in the nut over time. It seems most of it was early on. Keep the nut tight and the bearing greased.

Re: Used PT\'s
I could tell when hauling a load of rocks over uneven terrain this weekend mine seemed a little loose. Every 8 hours? There might be something to that. Thanks.
I find that the best way to tighten it is to turn the steering to the far right and this gives me good access on the left side.
I don't tighten it every eight hours, as it seems to have settled out with age and there has been little movement if any of the nut lately. It does concern me that others may never tighten theirs.
