Remove the torque converter cover
Measure the width of the belt at several locations If any measurements exceed the service limit, replace the belt.
Standard: 29.7 ∼ 30.3 mm (1.169 ∼ 1.193 in.)
Service Limit: 28.0 mm (1.102 in.)
Check the belt for abnormal wear.
When using the belt of large abnormal wear, the drive belt failure detection switch could be activated.
Check the belt for cracks, breaks, or peeling. If necessary, replace the belt with a new one.Whenever the belt is replaced, inspect the drive and the driven pulleys.
Drive Belt Deflection Inspection
Put the transmission in neutral and rotate the driven pulley by hand to make sure the belt is shifted all the way to the top of the driven pulley.
Measure the belt deflection by Place a straightedge on top of the belt between the drive pulley and the driven pulley. Use a ruler to push the belt away from the straightedge.
Push hard, but with no more force than 59 N (6 kgf, 13 lb).
Standard: 22 ∼ 27 mm (0.87 ∼ 1.06 in.)
If the belt deflection is not within the specified range, adjust the deflection by adding or removing spacers on the fixed sheave of the driven pulley. When adjusting the deflection, less is better than more. Less deflection will maintain better performance for more time as the belt width decreases by normal wear, which causes the deflection to increase with usage.
If the belt deflection is more than 27mm(1.06 in.), remove the spacers to decrease it.
The rule-of-thumb is: 0.1mm(0.004 in.) change in spacer thickness equals about 1.3 mm (0.051 in.) change in belt deflection. If the adjustment cannot be done within the specified range even if the shim is removed, replace the drive belt. If the belt deflection is less than 22 mm (0.87 in.), add the spacers to increase it. The rule-of-thumb is: 0.1mm(0.004 in.) change in spacer thickness equals about 1.6 mm (0.063 in.) change in belt deflection.
When using the plural spacers, install the thick spacer to the movable sheave side and thin spacer to the fixed sheave side.
