Yes, I would be suspicious of that check valve as that is your source for hydraulics to the cylinder.....odd that you can move it but could be intermittent. As an assembly I don't think you can take it apart. No reason to suspect the cylinder, it doesn't do anything except align the intake/output ports.
Would agree, best bet is to probably swap the 7B2982 valve assy. and see if the
problem follows.
Rick: Check to see if the other steering clutch lever is snug against the rubber snuber at the lower part of lever. If it is, adjust yoke so it has a little free movement at rubber snuber. If I remember correctly, push forward on opposite lever and see if the lever giving trouble will work correctly. This happened to me years ago on a 5R D6. Just a thought. Darrol
That does jog a faint memory....seems one valve has influence on building pressure in the other if slightly off the return position. Should be .020 in. free play on the lever push rod. Some of em get so worn/sloppy it's hard to tell where your at.
Thanks for the responses. I replaced the valve assy with one I pulled out of my parts machine today. I have the transmission oil drained right now so I didn't get to try her out yet. The adjustment on the right lever may very well be off a little. I'll get it going tomorrow and report back if one or the other solved the problem. Thanks again!
rick,
I have an off brand crawler that I was having strange cross actuations on the bucket, lift and 4n1 cylinders.. It turned out the return spring on the lift(raise/lower) 1st priority control. was broken and not returning home. It would intermittently block the return port and the dump from one of the other cylinders would cause inconsistent cross reactions. Once I found and changed the spring I have had no other strange cross reactions.
I suspect that a stop out of adjustment may be causing the same problem for you. especially if one is a priority over the other and apparently not parallel feed. My off brand has pedal steer but there are about 4 places that adjustments can be made that could affect my steering system similar to yours.
Hope this helps
Cheers

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
