getting ready to put order for A & I clutch for
replacement. A-160971AS (full face) vs A-163935 (4 button). what are differences in performance and longevity ?
 
FYI, Early 1650 tractors used a clutch with woven facings. At serial number 187*** the clutch was changed to a button clutch. When the button clutch came out the flywheel was counterbored too. There were also kits with spacers so you could use a button clutch in an older tractor. If you have a button clutch now which is what you should have make sure you measure the counterbore. Probably 95% chance your flywheel will need to be surfaced. Also get a new pilot bearing!
