ISSUED JUE , 1979
To All Dealers:
1. Subject #1
1.1 Poor clutch action due to abrupt engagement of transmission drive belt.
2. Service Action, Subject #1
2.1 Order Service Assembly 105189 from your distribution center and install as follows:
1. Cut RH belt guide off clutch mounting bracket and remove the #8205 stationary idler
pulley (Fig. 1). Retain the pulley and two 3/8 washers for re-use.
2. Install the supplied spacer block under the frame, using the RH rear engine mounting bolt.
Tighten bolt so that the spacer block can still be moved (Fig.2).
3. Assemble the idler pulley and washer, along with the new parts supplied, to the spacer
block as shown in Fig. 2. If the bolt "bottoms" against the frame, either shorten the bolt or
add additional 3/8 washers, as required.
4. Rotate the spacer block until sufficient belt tension is obtained, then tighten the engine
mounting bolt. Adjust the belt guide to obtain the clearances shown in Fig. 2, and secure in
position.
5. Test for proper clutching action. If belt engagement is still too severe, rotate the spacer
block to lessen belt tension, and readjust belt guide. A number of adjustments may have to be
made to obtain the best belt clutching and declutching action. In severe cases, the belt can
become stretched beyond specifications and may require replacement before proper
adjustment can be obtained.
3. Subject #2
3.1 Interference between shift stick and frame, preventing proper engagement of 2nd. gear
(Fig. 1).
4. Service Action, Subject #2
