    Do you have cables or straight linkage going to the spool? I've resolved some sticking issues, that give the illusion of a detent, by servicing these. Also, be it pedal control or lever, there are the bushings on the shaft below the cab floor, including lack of grease. A bur in the mating pieces of metal cam cause sticking. It's unlikely that it would be the plunger, or the spool, but possible. The bore is always full of oil & supported along its entire length. Haven't had mine apart for a while, but there is only one 'O' ring & a wiper at each end of the plunger in the spool body.
    I would also take the cap off at the rear & check the condition of the spring.
    There is an actual 'detent' on the back of the spool, that keeps (returns) the plunger to the 'not engaged/neutral' position, once you release the control lever from the back or forward position. You could have a 'sticking feeling' there, that makes you have to push or pull to overcome it. There are a few ball bearings in there also. This is the only place & the most common place, other than the ones I mentioned, that could cause the plunger to stick.
    If a parts breakdown picture from the parts book would help you I could post that.
    If there is damage there & you can't source the part, I may have one, but I'd check those things first.

    It has both types of linkages cable and solid rod. I went ahead and pulled the whole valve out. A hose came internally and a bit of wire baked itself up at the valve. I tried doing it in the machine but I made it worse driving the valve out. I took it to a friend who does hydraulics and he polished the high spot or of the valve. So I will be reinstalling it later this week. Hopefully it does not leak to much but we will see.

    I was able to talk to a husco engineer and he sent me the print on the spool if anyone ever needs one made. That may be a winter project if this does not work out well.
