TO-35 Clutch

After both halves were bolted together, I wanted to test the clutch linkage before finishing the assembly. Unfortunately, I cannot disengage the clutch using the clutch pedal. Observing this from access plate below clutch housing, I can see that the bearing does not even reach the release levers.

During assembly, I noticed that the release levers were being depressed as I tightened the clutch to the the flywheel. I suspect that I must leave some clearance between the clutch assembly and the flywheel. Is this correct? Note that I did not disassemble the clutch assembly during this process, so the problem is not related to a clutch R&R.

Additional problem: transmission was shifting easily until it stuck in gear (1st?). I can no longer shift gears with the R,1-3 lever. I will probably need to remove the steering column to resolve this, but any hints would be appreciated.

Thanks for the link... I will read a little later. I re-split and assembled the tractor last week and now the clutch is working. I didn't see any warpage on the PTO disc, so I have to assume that I had it right the first time around. My guess is that I simply wasn't applying enough force to the clutch pedal the first time around :{ Since this is my first time doing any mechanical work, I'm going to forgive myself for the stupid mistake... this time.

Now, most everything is together, but I want to double check the wiring before starting it up. I missed the end of month deadline I set, but it is nearly driveable, so again, I will forgive myself :)

Thanks for all the useful replies. I found this very encouraging.

The 2 halves must come together smooth, usualy with a "clunk" sound and completely together.

Look at the splines of the disc. Do you see any marks of mis-alignment?

You can buy just a PTO disc. You would not have to buy the entire pressure plate.

Hope this helps!

Thanks. I'm at work now and can't look at the splines now. I suspect this is what happened. I did in fact roll the halves together with a little help - some clamps :-0

Even at the time, this practice seemed a little, um, foolish.

When this happens, is the PTO disc still serviceable? Would I notice other signs of stress, like breakage?

One final question (for now at least): when I re-split the tractor, I noticed there was a coating of black on the release levers. It looks like carbon or something. If my bad memory is correct, they were clean before I bolted the halves together. Any insights into this?

Let me know what you find when you have it out.

Thanks for the tip. The cover is already off at this point - I'm impatient ;). I will remember this tip if it happens again.

The original post should have gone out two days before.

Last night, I split the tractor again. I was told I had a single clutch when I bought it. Foolishly, I assumed this to be the case until last night when I noticed the primary and secondary discs...

We are trying to figure out what the problem is, but we can't until I figure how the clutch assembly works. The dual clutch is a little more complicated and I am not a mechanic.

Again, any advice?

P.S. I also removed the steering column/transmission cover. I will see if it sticks in gear when I've reassembled again.

Yes, I'm too hasty. I'm determined to drive this beast out of the garage by the end of the month. It's been sitting there for a year now and I need to light a fire under my butt...

Also, the first thing we tried was adjusting it at the pedal. Before splitting it again, I was looking at the release bearing from the access plate underneath... agiain, it didn't provide a solution.

Thanks for your input.
