Winch info Timberjack 230A

[Road Apple]

Trouble with Eaton/ Hercules winch 1991 230A, want to winch in, with lever in release mode. It kinda just did this no warning no troubles just started not wanting to release. Some reason it usually is fine the 1st few hrs then it starts bothering. If the transfer in gear it will winch while trying to move forward in release mode. I've been told it may be the disc got oil on them and it's causing it to drag. I don't know set up for sure but it will winch in while in release mode till it stalls the skidder or breaks a choker. That's why I myself think it's hydraulic related thinking the clutches should slip before snapping a cable. I've already checked and cleaned the poppet valve's it's not that. I'm wondering if its in the valve bank to winch itself? Again after an over night some mornings it's worked like it should?  Any info would be appreciated.

It is either a seized drum bearing, or hydraulic valve bank problem. The brake is obviously stopping it rotating the drum in the mid location, but not the freespool position.

Look to see if the clutch pressure plate is pushed left under clutch hydraulic pressure (or check to see if there is hydraulic pressure at the clutch line) when the control is in the mid or freespool location. You can see if the pressure plate is loaded because it won't touch the limiting nuts through the pressure plate. If you have constant hydraulic pressure to the clutch, it is a valve bank problem.

If you don't have constant hydraulic pressure to the clutch, and it still winches, it's bearing failure.

I went and cracked the line to the side that activates the winch while in free spool and no fluid came out so I took the  gaurd off the drum and the bolts with sleeves going through the pressure plate? Had about  a 1/8 of an inch of sleeves showing while in release mode.

What am I in for when replacing the bearing, do I want take the winch out will anything else need attention? This really had no warning and sometimes was working fine. I haven't been able to run it much time since it started till the point I couldn't stand pulling my guts out to get the cable to come out. Thank you very much for your help, I searched winch trouble then found this site and joined it  in hopes to get some help figuring this out.

The difference in pressure plate location between free and engaged should be 070". Generally the nuts through the pressure plate are touching in the free and hold position, and only show the 070" when winching.

If you have no hydraulic pressure during freespool or mid location, it is not the valve bank causing it to winch in.

To replace the drum bearings, you have to remove the winch. Stand it on the gearbox end and remove top (right) side first until you can lift the drum off the shaft.

Thank you, very much Neilo

I've dug into it, do I need a puller for the bronze gear to get drum to come through? I was told to pull the pinion shaft out also. This is a far bigger project than I expected the clutches looked good springs also did almost everything looks great but I'm now into getting the drum out but dont want frig it up. I see there's threaded bolt holes for a puller? Or use the to press this out I stopped there because I'm not sure which one to do? Sorry to keep bugging you but the locals my way want me to bring em the winch and have them do it I can't afford to. Especially when I know I can do it  I just need a little more info on want to do now.

Also is it possible for the clutch cylinder to hang up?

[Road Apple]

I'm not sure what to say, I've worked on it too long and now need [I have typed a profane word that is automatically changed by the forum censored words program I should know better] pressed out, I called a guy that works on these things and he said he doesn't think it's the bearings but I'm so far into it now to put em in I've been out of work  for 10 days now. The guy is going to press new bearings in but says he thinks it must the clutch cylinder is hanging up. Said he has worked 100s of these things. I hope its not it' becausethat alone is $500 on top of this. This was by far not just a simple disassemble. I guess I'm going to find out.

What did it end up being?

Solo33 you might wait a while for that answer.  Road Apple ain't been around here sense 2019.

I just got done working on mine. About wore me out trying to pull cable, not the same problem. I pulled the clutch plates and cleaned them up and the groves up.I also adjusted the brake clearance while out. Put back together and back on. Now the cable releases under the weight of the slides. I have not used it yet, but hoping for good things.
