Hey I was wondering if you guys have any more ideas about why my aux hyraulics are not working on my 863? I tested the the trigger with the meter and its reading exactly what the service manual says and I tested the two aux hydraulic solenoid valves on the control valve and they are reading good also. In the manual it says about a rear aux diverter that has two solenoid valves on it but I cannot find this diverter. Does anyone know where it is located on the 863 machine? I talked to bobcat and they want me to bring the machine to them so they can test the pump, but before I put the money out to take it to them I want to check to make sure its not something simple first. So any ideas are greatly appreciated. Thanks
 
In future please don't start a new thread when there is one already active, if you want it bumped back up just post in it again. Remember not every fault has been experienced by everyone so we can't always come up with a solution.
I have posted in your old thread, see if it helps.
 
Sorry Tazza, I'm new to the site next time I have a question about this site or consider posting something I will consult you first. Are you the one that polices this site?

Thats not needed.
We just like to keep things in order is all, if someone hasn't replied to your first post, post another question in it and it will bump the post to the top again. There are no set rules or posting guide lines around here. We just don't want someone to say have a problem with a Deere machine and post the same question in 3-4 different places expecting it to speed up the reply.
So don't feel you need to talk to any of the mods before you post, its really not needed. Some forums can be really strict, we really aren't and there are very few fights/arguments around here because of just that.
 
If it was a problem with the pump you'd be having trouble with the lift and tilt too. It may not have the rear aux diverter valve in it. I think that was an option for when you have rear stabilizers installed. If I remember correctly, the valve was located near the battery area. How old is the machine again and what is the aux. doing/not doing??

I think the machine is a 1996 model. I'm not getting anything from the aux. not even a trickle

I tried what you mentioned about taking the nut off the coil and seeing if the coil pulled itself back and the one did. The other one I could not pull it away. Does that mean the coil and stem is bad on that side? Should I replace the coil and stem on the one side and leave the other one go or does both stems usually go bad together? Thanks

Stems don't normally both go BUT my 753G i just got, one stem was bent so it was dead, the other was sticky. I replaced both stems and it now works 100%. I bought new coils too just to be sure, they were cheap enough to have on hand just in case.
Stems aren't really cheap, about 130-150 USD for mine, yours i can't be sure but I'd expect around the same range.
I was fiddling with them yesterday actually, the broken ones that is. You can actually disassemble them. I got into one with my lathe to see what was inside and found there was a thread so you could pull it down (to an extent). Naturally i attacked the wrong one first (the sticky one) so the bent one i un-did with ease.Not that it can be repaired.... Quite interesting all the same.
From what you are saying with the coil pulling down, it has to be the stem.

ok I'll replace the stem on the side the coil is pulling down. Should I replace the coil on the other side that isn't moving?

So the coil is stuck? or its simply not pulling against the stem?
Easy way to check if its the coil is to swap it with the one you know works. Just un-plug it and put the known working one in. If the problem swaps sides the coil is bad. You can even remove the coils from the stems and see if the coil pulling will operate the other stem.
