Install the bushing (3) in the flange yoke (2). Assemble the other parts
of the clutch as shown in the previous diagram. Avoid contamination of
the surfaces with any oil or grease.
Fully loosen the four socket head screws.
Install the eight bolts. Tighten the bolts progressively, and in an
alternating pattern in order to compress the spring uniformly.
Tighten the bolts to 27 Nm (20 ft . lbs).
Back each nut off by 1/4
turn. The spacer ring (8)
should rotate freely.
If spacer ring does not
rotate freely, back each nut
off an additional 1/8 turn.
Continue backing each nut
off 1/8 turn until spacer ring
rotates
freely.
Re-insert the taper pin into the hub.
After new linings are installed, the torque setting will be low until the linings “seat” against the metal plates. After
the first few slips, the torque should rise to the nominal setting.
At the end of the season or before any long period of non-use, fully tighten the socket head screws to
relieve the pressure on the linings. For best performance, store the clutch in a dry place to prevent
sticking.
The FT clutch utilizes a Belleville spring to provide a consistent torque
setting during the life of the friction lining. The spacer ring ensures the
accuracy of the spring tension setting.
The clutch torque setting is stamped on the face of the flange yoke
between the bolts.
