Belt Deflection (Tension) (NON EBS ONLY)
Belt Deflection (Tension):
Maximum 1 1/8” (2.9 cm)
Pinch the sheaves lightly together with clamp to prevent
the belt from being pushed into the driven sheave.
1.
Place a straight edge on top of the belt between
drive and driven clutch.
2.
Push down on drive belt until it is lightly tensioned.
3.
Measure belt deflection as shown in the image
above.
If belt deflection is out of specification, adjust by
removing or adding shims between the driven clutch
sheaves.
• Remove shims to decrease belt deflection
• Add shims to increase belt deflection
Refer to “Driven Clutch Service” section.
At least one shim must remain between the inner
and outer sheave of the driven clutch. If proper belt
deflection cannot be obtained, measure drive belt
width, length, and center distance of drive and driven
clutch, outlined in this section; all have an effect on
belt deflection.
Setting Center-To-Center Distance
Clutch center distance is controlled by the correct
positioning of the engine and transmission mounting.
The 10” Center Distance Tool (PN 2871710) should be
used for the following:
• After engine installation.
• After transmission installation.
• After engine or transmission mount replacement.
• If the vehicle exhibits drive clutch drag or hard
shifting while at idle speed, after clutch offset
adjustment has been performed.
