    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.

    If anyone in NW Ohio is looking for a HyHoe, most likely for parts, there is one about to head to the scrap yard in Fremont, Ohio. I didn't grab the model #, but its a later model one with the typical excavator style undercarriage. I did grab a pic, but I don't know that I can post yet. I'll try. PM me for more info. The boom is quite patchy...

    Hard to tell by the pic, but, if it's a 5000, it'll have 2 upper carrier rollers (per side). The 6000 has 3.
    Looks like a 5000TT

    Just finished it up. It's up and going. We filled the scratched and polished it down. It works for now. Since I had all the oil out I went ahead and resealed a leaking track motor and resealed that whole valve body. And wow that thing takes a bunch of oil. I was going 60 gallons would do it just to get by. I was not even close to the sight glad yet.

    Anyone have a factory 36" bucket for a 685B. 3" pins and 12" wide stick width? Figured id try finding one before adapting a bucket from a 160 size machine.

    I do have a few Hy-Hoe buckets. One is brand new (factory original), never used, with the Hy-Hoe name on the side. The rest are for Hy-Hoe but made by Nye... Sizes range from 28" to 42" Have to check for sure once the snow is gone. All but one are for 3" pins. One bucket has 2 3/4" inch holes. That would have to be line bored to 3".
    Once the snows gone, I'll check it out & decide what I'd like to do with them. If you're still looking.

    Check out my last post (meant for you). The new unused Hy-Hoe bucket I spoke of is identical (except for being new), to the bucket on my old 685 B, that you can see in a pic I posted on page 10 of this forum, on Aug. 11, 2018. My memory is that it's a 42" bucket, with a 1 1/8 cubic yard, struck, capacity. The others range from 3/4 to 1 cubic yard & measure 24" to 40" I've had really good luck with that bucket. Was well matched for my 685 & I got both, new, direct at the Hy-Hoe dealer/factory (now long gone!). Other than an Esco.., definitely the best buckets I've had.
    I may be switching the bucket shown on the same pic, on the 5000 TT. That bucket (that I retrofitted) came off a J.D. 892. Capacity on that is around 1.5 + cubic yards.
