So I'm out snowblowing this blizzard we're getting and when I go to lift my blower for the last time I give the lift control a tug and the lever just wants to keep going past it's stop point.

I got it back into the garage and looked under neath it but it doesn't look like anything has come undone. The linkage is all still intact and the lift valve works it just wants to pull the valve part out of the TCV.

Any thoughts? Do I need a new TCV?

Chuck, There is a screw that goes into the back side of the spool. It is under the cover. There is a lot in there including detent springs and balls so you probably want to check the manual before tearing into it. This is if everything on the front (control) side is as it should be. Gregg

I had the same thing happen last season causing over travel and binding linkage. It turned out the springs had become corroded in their sockets and would not allow the detent ball to hold position. Cleaned and greased and all is right, but it was a chore getting the cover off the back of the TCV. I had to disconnect the neighboring hydro lines and unmount the TCV enough to tilt it downward to get clearance for the big wrenches, if I remember correctly. It became a good opportunity to change the hydro fluid while I was at it.

Good luck :thumbup:

Oh goody and I thought it was going to be a pain.....

I'll have to disassemble it after the snow goes away.

There is a screw in the end of the spool that holds spring onto spool-maybe it broke or came loose.Could be easy fix(of course these problems never happen when its 70 degrees out ,right!!!!

I'm going to look for a used working spool and then rebuild this one as a spare. I've got a bungee cord holding up the lift lever right now as we just got hammered with snow with more on the way on Wednesday.

If anyone has a spare TCV pm me. It's the plain jane one with no holding valve.

While I was just out plowing the back 40 I was thinking about this post. My memory cleared and the difficulty I had with the cover was this. There were two phillips head screws holding the cover on and because the TCV is mounted up in there pretty tight I could only really access the one screw. After looking at the parts breakdown I was concerned I was going to need more elbow room to make unknown repairs anyway. To dislodge the TCV from the frame I needed to disconnect and remove the solid hydro lines. After I had some room to work with the rest was easy. Depending on what your actual problem is you may need to remove the TCV anyway to give it a good service. I think I debated this at the time but I was under pressure to get it working because the snow was getting deep!

Hope this helps.

It's actually worth the effort to pull the complete valve from the tractor.

Look in your parts manual. Trying to install those tiny ball bearings and springs in a cold garage while working under the tractor is not my idea of a good time. It's much better to take that valve apart in a well-lit warm room on a bench with a clean rag under it to catch small parts that try to disappear on you. Much less swearing that way.

Chuck, I'm going to be staying in Thomaston Monday night if you want a hand with that control valve. Gregg

 

[Snotrocket]

I would take you up on that if I had the one I bought in my hand then. :thumbsup: It probably won't be here until later this week though.

Plus I would actually have to clean up my shop before I let you in it. :sidelaugh: :sidelaugh: :sidelaugh:

Well I got the "new" TCV in it tonight. Everything seems much tighter than it ever did with the old one. I would like to give a big thanks to unclecake who sold me the used TCV for a good price.

I'm waiting on my new starter which should be here on Monday to test everything out.

Congrats!
I just want you to know I personally put in the word to hold off the snow until you were done. I'll get you 2 more days :lol:

You're going to rebuild/repair/renovate/whatever the old one, right? Some pics of the process would be great addition to the forum (hint, hint :wink: ).

 

[Snotrocket]

Yeah I'm probably going to rebuild the old one at some point. It would make a nice valve for a custom rear PTO and maybe use the other side for a power angle for a plow. :mrgreen:
