PERIODIC MAINTENANCE 2-25

Periodic Maintenance Procedures

•

Check the belt [A] for abnormal wear [B].

○

Measure the width [C] of the belt at abnormal wear point.

If any measurements exceed 0.5 mm (0.02 in.), replace

the belt.

○

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.

Belt [A]

Crack [B]

Broken [C]

Peeling [D]

NOTE

○

Whenever the belt is replaced, inspect the drive and the

driven pulleys.

Converter Drive Belt Deflection Inspection

•

Remove the torque converter cover (see Torque Con-

verter Cover Removal in the Converter System chapter).

•

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 [A] as shown:

○

Place a s traightedge [B] on top of the belt between the

drive pulley [C] and the driven pulley [D].

○

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).

Belt Deflection

Standard: 22 ∼ 27 mm (0.87 ∼ 1.06 in.)

If the belt deflection is not within the specified range, ad-

just the deflection by adding or removing spacers on t he

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.
