Does anyone know a source for the three pressure plate buttons? Pressure plate and disc look good and we plan to reuse but the buttons have significant wear. Thanks
 
I'd check for a place that relines clutch's. If you don't know of any, use Google looking for "clutch relining".
 
Replace the whole thing. The pressure platesprings may be getting weak. The flywheel is probably grooved as is the PP surface.Is the PP (or flywheel) heat cracked?.other issues may exist. Why do it 'half a$$ed when you can do it right the first time.A clutch kit really isn't very expencive. I know you want to 'save money'.But that is not the place to cut corners.How much money are going to save if you have to tear it apart again? 6 months? year?....."spend a dollar to save a nickel".
 
357301R1 Not available but you might have a cooperative dealer search the country for some old stock. Also, a new clutch disc will measure about .390 (relying on memory here) so if it is like 1/16 less than that it is pretty well shot. If your checkbook is like mine, you can take things apart again cheaper than just playing it safe. If paying someone else to do it , that is a whole different story. I work really cheap for myself and actually pretty cheap on others stuff.
 
What parts are you calling "buttons"? This is a pressure plate for a 400-450-560 tractor. The clutch disk style is what a lot of people call a button clutch.

A brake, clutch, and industrial friction shop a couple hours from us does this all the time, will rivet them on for you, grind the flywheel and pressure plate for you, then clean, assemble and set the pressure plate fingers for you, replacing springs as needed, how ever or how much you want them to do.

Likely, there's such a place near you.
 
I took it to mean he has the clutch pressure plate that uses the button on the tip of the fingers. Never saw a disc on 450 with three buttons but have seen pressure plates with them on fingers like Super M used and later tractors also used.
 
If it's the three fingers on the pressure plate shown,inspect the throw out bearing to be sure it's OK.Not dragging,stuck, or.........
 
If it's like the plate pete23 is referring to with the little adjusting bolts that heads contacts the release bearing near end of fingers. Think a dealer has a new strange number for those, 25978R1.
