Yanmar Tractor Clutch disc, 8” x 1”-13 spline
Shop Tip:
You need to line up the clutch disc to the flywheel before tightening down the pressure plate bolts. Many vehicles require you to buy a special line up tool but Yanmar tractors have one built in! The clutch shaft is splined into a coupler that joins it to the transmission input shaft. Just slide the clutch shaft out of that coupler and use it as a line-up tool then slide it back in. This is also a great time to check the splined coupler to be sure it is not damaged or loose.
