...and so the story begins. Not sure if anyone remembers, but a while back I kept having trouble with my steering. The solution seemed to be:
1.) Buy some power steering fluid.
2.) Pour it in.
A buddy of mine told me to put in a little brake fluid and if there was a leak that might fix it. I never figured out how that could work, and in fact, it didn't, so I kept a bottle of power steering fluid handy to top off the reservoir. Actually, I had to sell my 30-30 that I used to keep in the rifle sling on my role bar, so I kept a bottle of PS fluid in the sling. It's not as effective against coyotes as the 30-30, but kept me rolling. I always figured that some day I'd get motivated and find that leak.
Some day found me.
The good thing is that even someone as mechanically declined as me could find this leak. It was very impressive. The slightest turn of the steering wheel and fluid would spray out of the cylinder that controls the wheels.
Well, I grabbed my handy dandy bottle of fluid, and poured it in the pump. It took the whole bottle to fill it up. I started her up and headed back towards the barn. Most of the fluid sprayed out just turning around. I made it about half way back before I had no ability to turn. Funny thing about the steering on my 6610 is that if there's no fluid, there's no steering. You can spin the steering wheel to your heart's content, but she just goes straight. I walked back to the barn and got another bottle of fluid, filled it up, and tried again. The furthest I could get was the barn lot, that took two more bottles of fluid, but that was close enough for me to do what I needed to do. Here's where the fluid was spraying from:
Right around the piston as it comes out of the cylinder.
Right about here is where I really wished that we had a "phone a friend" feature on TBN. But, then 3RRL would probably get tired of me calling him up. I looked it over and decided that I could pretty much remove the entire thing and take it to someone to fix.
I realize this is pretty elementary to most of you folk, but it's all intimidating to me. (I'm saying that because at the end of this story I'm going to be very proud of myself even though it might not impress the average TBN'er, just humor me.

)
First I had to disconnect the fluid hoses:
I didn't have a full set of tools, so I had to do what I could, which meant taking the hose brace off the tractor too rather than just unscrewing the hoses:
Then came the fun part. There were these HUGE nuts on either end of the cylinder. (No wise cracks there, this is still a family show.) I figured that they had to come off, and then it looked like the remaining bolt and ball joint should just slide right out, right?

Wrong. This is a 1991 tractor, and it looked like this was all original stuff. In this picture, doesn't it look like you could just lightly tap the end of that bolt and the thing would just drop out?
Well the tapping turned into full fledge sledge hammering. From previous such instances, though, I have learned, don't mess with things that have threads. I'm sure that is in some mechanical handbook somewhere. I've managed to destroy lots of stuff with threads in my day, and it's never easy to recover from. So I did phone a friend. He told me to put the nut back on the bolt and hit the nut. That would help keep from destroying that bolt. He also said to put a piece of wood between the hammer and nut to try to keep from damaging the nut. That didn't work at all. I couldn't get the bolt to budge. Finally I decided to sacrifice the nut and just beat the tar out of it. And that worked. Unfortunately I didn't get a picture of the nut, but it was quite funny looking. I used the same nut on both ends so I only had to replace one of them.
I took the cylinder to the local Ford/NH place and they said that the cylinder was pretty much shot. They found a rebuilt one for a couple hundred dollars and ordered it for me. Next I got to take this:

and turn it into this:
(Pat on back.)
I put the newly rebuilt cylinder back on the tractor, filled up the pump, and I was back in the saddle! To my amazement everything worked just fine. While it's not exactly like I retooled the cylinder in my garage, I did feel good that I'd found the problem, got a replacement part, and put it all back together.
So I'm off to log some more hours, and see what I can get into next. Now I don't have to keep the bottle of fluid handy, hopefully I'll have another rifle to put in the sling soon. Happy tractoring.
