Thanks guys

Appreciate all the input. Still waiting on the manuals, apparently even the CD version gets shipped by mail, after it is made... so it may be a while before I see anything. It's that metallic whine that had me worried more so than anything else.

Don't know about the 750 model but some of the tractors have a place to grease the clutch pack thru an inspection cover that comes off. I would check into this before I split the tractor. This should be greased sparingly with only a shot or two.

Hi again guys

I went looking for an inspection hole, I did find one but I can't see much through it only a small portion of the fly wheel, or at least I think it's the fly wheel.
I fired up the machine today to try and see if I can free the clutch, I put it on a low gear, pushed the clutch in all the way and hit the brakes a few times, I think I only did this twice and I noticed the clutch pedal lost all resistance it still returned to its upright position, but pushing down on it was effort less, I stopped, shut the engined off and checked the inspection hole, there were metal shavings in the rubber cap, and smoke coming out, so I think I need to split it and see what failed. I'm still waiting for the manuals, but I'll try and get started this weekend remove some components to split this machine and get the clutch working. Ill probably replace any seals I find in there as well.

Cheers!

xp190,

That is a Bummer. I hope you were able to get this tractor at a cheap price.

I did get it cheap, so some repairs are to be expected which I don't have an issue with. I never fixed a clutch before, but I can't imagine it being too difficult.
I started working away to split the tractor, seems like it was designed to get it done fairly quick, but the hydraulics have me stumped, so I think I'll wait for the manuals before I proceed.

From looking at the diagrams, I think what happened is the release bearing fell apart, as in totally apart, hence there is nothing pushing back on the clutch fingers to release it.
I think the flywheel should be fine, but I won't know for sure until I split the thing and take a look inside.

Are there any tricks to working with the hydraulic system? Can I drain it and disconnect the lines? Is there a way to prime it, or is it self priming?

Yes, you can and should drain your hydraulic resevoir. You may find it easiest to drain the Hyd. by disconnecting the line from the puimp and letting it drain into buckets. Very clean buckets if you intend to reuse the fluid. Myself, I would buy new fluid and plan on chaging filter as well.
Some tractors have two hyd. pumps, one for steering, one for hydraulics. You will need to know what yours is.

On some tractors, you can open a hydraulic line going to your power steering cylinders and moving your steering wheel back and fourth to remove air in system to (prime it). Your manual will say for sure how to.

If you have never split a tractor, then begin gathering two very sturdy sawhorses(metal pipe is preferred). Chock blocks for blocking front and rear tires on each side(8 blocks) once you separate the tractor. A highlift floor jack may be needed as well.

Thanks wolf

I'm going to support the rear end on 2x8s and a high lift 2.5tonne jack, for the front end I have an atv jack which can do 2500lbs, but before I can do that I have to remove the drive shaft that powers the front wheels, seems simple enough, but I couldn't get the covers off for some reason, maybe my hands were just tired.

I don't intend to reuse the hydraulic fluid, I'll replace it, and at the moment I have no idea where the filter for it is. Only a single pump on my tractor, no power steering.

Thanks for the advice, this should be a fun project, probably a big shopping list of parts to go along with it.

Hydraulic jacks have a way of bleeding down or blowing seals under prolonged load. Can you build or assemble stands to lower the two halves onto after you split the tractor? Perhaps only an inch lower than the lifting points on your tractor, then a wooden spacer block to fill the gap.

Once apart, lower the two halves down onto your solid stands. I have yet to have every part I need on hand when doing something like this and usually have to order a part. Meaning days sitting on hydraulic jacks.

Even concrete blocks stacked will be safer. Once you have replaced the parts and are ready to pull back together, lift with hydraulic jacks and remove your stands.

Good point Wolf, I'll put something together out of 2x8s and use the jacks only to move the two halves apart. When working on cars I usually have jack stands to take over for the jack.
