installing a new belt, check and adjust
the drive belt deflection as described in
this chapter.

Inspection (Except 1997 ZR 580)
CAUTION
Do not scratch parts by cleaning with
steel wool or a wire brush. Clean parts
with a suitable cleaning solvent only.
1. Clean all parts thoroughly and dry with corn-
pressed air.
2. Check all parts carefully for cracks or darn-
age. Do not install any parts that are cracked.
3. Check the drive belt surfaces (Figure 66) of
the sheaves for corrosion, burrs, nicks or any
buildup of rubber. For proper operation, the sur-
faces must be
clean
and smooth.
4. Check the torque bracket ramps (Figure 67)
for wear, scoring, gouging or other signs of
damage. If damage is not too severe, you can
smooth the surface with No. 400 sandpaper. Re-
fer to Table 6 for original application.
