I have a mid '80's John Deere 210 backhoe that appears to have an issue with the shuttle/reverser box, machine will go ahead fine but doesn't seem to fully come out of gear when in neutral and when in reverse it seems like both forward and reverse clutches clutches are engaged. We got it lifted up on the stabilizer pads and with the rear wheels off the ground and in neutral the wheels are going ahead, shift into forward and they continue running ahead at the same speed, shift into reverse and they change direction but are moving slowly, while in reverse i pushed the button for the "clutch" solenoid and when it dumped the wheels started going ahead again, let off the button and it again starts going reverse again but slowly. After reading a bunch of posts, including Bowens excellent write up, it seems that either the spool valve is faulty and allowing oil pressure to be directed the forward clutch all the time, or perhaps something has gone wrong in the forward clutch pack and they are mechanically locked together? The fact that the clutch cutout button seems to be working but the wheels still want to go ahead makes me think that perhaps the 2nd scenario is what is going on? Look forward to hearing any thoughts folks may have on this. I have never dealt with these reverser's before and look forward to learning more about them. Thanks
My thoughts would be the broken spring in the fwd clutch pack senario. This is usually the cause of exactly what you have described. If you drain the oil & pull the pan it will have it's fair share of metal fragments in it....
i will pull the pan Monday and see what i find, either way it sounds like i will have to pull the reverser.
pulled the pan off the shuttle shift box and found lots of metal flakes and the magnet was completely covered, not sure if i would be better off attempting to rebuild or look for a reman unit. Based on the amount of metal in the pan i think a new torque converter and a good cooler flush or replacement is going to be needed.
The torque convertor & oil cooler should definitely not be overlooked. A good car auto transmission repair shop should be able to recondition your convertor at a reasonable price. Here, I use a shop that simply repairs convertors & nothing else. The shuttle/reverser overhaul is too difficult, if you have a service manual & some above average mechanical ability.
NOT too difficult (I'm sure he meant). I haven't done it, but you can search and see how many people have done it successfully on their own, the second or third time if they didn't pay attention the first time.
Paying for parts is the hardest part, getting it on the bench is next...
