13. Measure the clearance between the clutch end plate
and top disc with a dial indicator. Zero the dial indi-
cator with the clutch end plate lowered, and lift it up
to the snap ring. The distance that the clutch end
plate moves is the clearance between it and the top
dtsc.
NOTE: Take measurements in at least three places'
and use the average as the actual clearance.
