MAINTENANCE

TWR-180/TWR-120 12/04

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.
