friction disc wear.

To adjust traction clutch:

3. Measure the length of the traction drive clutch

spring at the top of the traction cable. See Figure

loosen the jam nut on the cable adjuster.

b.Turn the adjuster body up the cable for more

spring extension.

c.Turn the adjuster body down the cable for less

spring extension.

d.Finger tighten the jam nut, and then hold the

adjuster body with pliers and tighten the jam nut

with wrench.

6. Measure the extension of the traction drive clutch

spring.

7. Repeat step 5 until traction drive clutch spring

lengthens 1/2 -11/16 in. (12.7-17.5 mm) when the

traction drive clutch lever is engaged.

8. With the clutch disengaged, check that there is

more than 1/32 in. (0.8 mm) clearance between

friction disc and drive plate assembly.

IMPORTANT: If spring length cannot be adjusted

within specified range, see your Dealer for repairs.
