14. Measure the clearance between the clutch end plate
and toD disc with a dial indicator, Zero th€ dial indica-
tor 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 the clutch end plate
and toD disc.
NOTE: Take measurements in at least three places,
and use the average as the actual clearance.

15. It the clearance is out of tolerance, select a new ciutch
end plate from the following table, then recheck.
NOIE: lf ihe thickest clutch end plate is installed but
the clearance is still over the standard, replace the
clutch discs and clutch Plates.
