So I can't seem to figure out my linkage problem. When I put the the control lever in the reverse position and step on the pedal, the pedal sticks and the tractor doesn't move. I've replaced a bunch of wear items in the linkage with the exception of the balljoint. I wasn't able to remove it from the valve, so I left it. My only other thought is that the valve control rod could be bent? is it supposed to be a perfect 90 degree angle?

When I crawl under the tractor and watch the linkage as I cycle the foot control with it in the reverse position, I can see that the balljoint is kicking out to the left and not depressing the valve. In the forward position it works like a charm. Love to hear what you all think.

I got some advice from a former Ingersoll dealer. He suggested that I remove the entire valve from under the tractor to remove the balljoint that way. He also mentioned that I should replace the metal lines with flexible lines because the valve is attached to the frame, and the motor to the axle. He said he has seen a few of these spring leaks because there is flex in the metal lines. Is that a good idea?

Lets say I muster up the courage to do this. How much oil is going to leak out of the lines when I disconnect the valve from the lines? Should I drain the entire system? I just changed all the oil 5 months ago as it is.

Any help is greatly appreciated.

I've had some similar issues with my 7020 though I haven't had a chance to determine the source of the problem. I've noticed that when I lift a load in the bucket on uneven ground I sometimes can't depress the travel control even with great pressure. The problem is somewhat intermittent but I suspect that it has something to do with flexing of the frame. I haven't had any such problem with my two other loaders that are older.

I just replaced the TCV on my 446. I assume it's mounted in a similar position as the one on your tractor.

It's good 2 hour job. You're going to lose most of your oil out of the system. I would suggest taking one of the lines off and letting it drain for a day or so unless you really like
making a mess all over yourself.

Are you talking about that little ball joint that is torqued to about 50000 inch lbs LOL?
I had to two long pattern wrenches and it made the job a whole lot easier.
Or get some crowsfoot for a couple breaker bars. No need to take the whole valve out atleast on the 600

Yes, that damned ball joint. When I put it in reverse and pull the foot control it seems to tweak out to the left and not depress the valve, and then the foot control stays depressed as if it's jammed. I'm not sure if replacing it will fix the problem as it seems the geometry is off. I figure I have a new one, I might as well replace it as it seems to have too much travel in it.

I'll soak that thing in BP Blaster and then, swing by the local discount tool place and try to grab as long a wrench as I can find. I think the valve is fine because when I do stomp on the travel petal it goes in reverse. I just think it is misaligned.

It's supposed to be cold again, and I still haven't installed that wood stove out in the barn. I'll need a wood stove forum before I tackle that project!

Thanks for all the help.

Mine wasnt rusted. It was just torqued to on there
Its pretty awkward down there and you can only get so much leverage.
The longer wrenches make it pretty easy

Sorry
I couldnt tell you why its called pattern. But after looking through tool catalogs 100x that is what stuck.

Just a long wrench is what I meant.

You doing some work on your backhoe?
