Think I just tore my clutch out. ford 1520

[JC-jetro]

I'm 100% sure its a dual clutch. I tried getting a pic but the inspection hole is really to small to get the light and camera angle Just right. I saw 2 disc in there though. its really hard to see the actual thickness of the disc themselves.

Barry,

On a dual clutch disk one can not see two clutch disks. I have not ever adjusted a dual clutch but I have read the instruction for a 1517 and 1710 in FO-44 manual. There are several bolts that adjust the tension of pressure plate for the pto clutch. see if you can identify the adjustment bolts. access to them are from the inspection hole. look at the attachment below for some guidance. There is one adjustment for the pressure plate fingers and the the throwout bearing and PTO pressure plate disk tension can be adjusted. what ever you do, put some witness mark by paint or something so you can return it to where it is now.

JC,


a Fleabay link for 1510 dual clutch.

What? wonder what I am seeing then. I clearly see what appears to be the sides of clutch disc. I went out and tried to get some pics. hopefully this helps. If you can tell, it looks like the clutch disc at the fly wheel. Then directly behind the bolt, it appears to have another disc..

Playing around with a prybar. I was spinning motor over to see what all is in there. Tractor off, transmission in gear. I can freely spin the motor without any sign of it wanting to move the wheels.

Barry,

yup. You do have dual clutch without a shadow of a doubt. What you have is shown naked below. with your description, your clutch disk might be gone, out of adjustment by much or the finger are heavily riding the clutch fingers. Can you see distance between the three fingers and the throwout bearing? I suggest you follow the instruction on my previous post for adjusting, can't do no more harm now.

No I can't see back past the pressure plates' housing. Only way to see for sure is split the tractor.
I with you, I feel pretty sure the disc is probably gone. For it to freewheel like it did, then started not working. all within a few feet. Definitely a learning experience That much I do know 100%. I'll keep it updated as I get into it. I'm still working on getting my Mothers Honda Accord Motor back together. I've got that just about ready to drop back in, next I'll roll the tractor in the garage.

Good luck to you Barry, Mom always comes first... no question asked. I had to do two timing belts and one CV joint on my two of sons accord and civic. I tell you , I do hate interference engines. The whole assembly is going to cost you dearly , try to check around in Fleabay for a better price. If you are not in a hurry may be do a split and inspect two pressure plates and clutch disks .. may be you can get by with changing disks only although there is so much work involved that you don't want to do this job twice. Give the adjustment a try , at least you learn the directions.

I suggest you zoom in on fig. 167 in the pdf JC attached above. You'll want to distinguish the 3 'PTO clutch adjusting bolts' (#9 below) and be sure the clearance between their heads and the PTO pressure plate is correctly .035-.040" (feeler gauged). Pedal free-play should be 3/4 - 1 3/16" measured at the pedal pad. (This per I&T's FO-46 manual who's $25 or so will pay back quickly.) If you have to adjust either of these very far you may want to run the previous tests again. If you replace your clutch, the I&T FO-46 will give you all of this and more. Oh sorry, I'm keeping my copy. :tractor:

 

[barryb77]

If I am reading correctly and looking at the diagrams correctly. The bolt I have pictured should have a .035 -.040 gap basically at the top of the head of the bolt.

 

[barryb77]

Out of the three bolts, one I was able to get my .035 guage into. the others were tighter, maybe .030- .032 There is no way possible for me to get the wrenches into those bolts to make adjustments without cutting the access hole bigger, don't feel comfortable doing that since the loader mounting bracket is bolted there. So even to adjust them, I'd have to split the tractor.. No I haven't been able to do much to the tractor. Ive got my Mothers car 98% back together, there is literally one bolt, holding me back from finishing it. Its a special bolt, so not just available in my spare bolt bin.

So I take it you can even take a box end or open end wrench and turn it just a few degrees at time?

JC,

No, The hole is in a bad location, There is a lock nut to the left of the hole and thats at to steep of an angle to get a good grip with a open end wrench. I tried. Just don't want to mess anything else up. I should clean up my shop go ahead and get the tractor ready for the fix. Once I get to it, It shouldn't take that long. Since the clutch rebuilders are literally across the street from the office I work out of. And the owners of the clutch shop are my office managers nephews. Maybe I can sneak in there and get the family discount.
