Remove the following inner components:

a. Spring kit (#6)

b. Pressure flange (#7)

c. 1st Friction Disc (#8)

d. Hub with flange and pull collar (#2 & #3)

Shearbolt Protection

Avoid shear bolt breakage by making sure the tiller is out
of the ground before engaging PTO and by engaging
PTO slowly at low engine rpm. Increase engine speed to
540 RPM only after tines are rotating.

See table below for correct shear bolt and nut part
numbers. Torque shear bolt nuts to 7-9 ft- lbs.
