Notes:
- Belt deflection must be checked and adjusted when the belt is cold (at room temperature).
- Belt deflection also should be checked at first 1000 km ride after belt replacement.
Check to see if wheel alignment is properly adjusted.
The left and right notches on the belt adjuster should point to the same marks or positions on the swingarm.
★ If they do not, adjust wheel alignment (see Wheel alignment inspection/adjustment).
Remove:
- Reserve Tank Cover (see Reserve tank removal in the Cooling System chapter)
Using the jack under the frame, lift the rear wheel off the ground (see Rear wheel removal in the Wheels/Tires chapter).
Visually inspect the belt for damage (see Belt wear and damage inspection).
★ If the belt is damaged, replace it with a new one.
Mark the initial belt position [A] on the belt cover window.

Using the tension gauge [A], push up 45 N (4.5 kgf, 10 lb) of force from under and on the center of the belt at the front side of the swingarm cross pipe [B].

Measure the deflection (length between initial belt position [A] and position [B] after it measure it) of the belt (at the belt cover window).

Notes:
- Push the belt by the gauge until the top surface [A] of the stopper comes to the 45 N loaded scale [B], marked "45N".
- Push up on the center of the belt. An inaccurate reading will occur if the edge of the belt is pushed up.
- Look parallel to the belt during inspection. An inaccurate reading will occur if looking from any other angle.

Inspect the belt deflection at two positions by rotating the rear wheel.
Special Tool - Tension Gauge: 57001-1585.
Inspect the drive belt deflection at arbitrary position, and record the value [A].

Turn the rear wheel 90 degrees.

Inspect the drive belt deflection, and record the value [B].
![](https://motoinstruction.ru/img/kawasaki/13/118556.jpg)
Decide the belt deflection at the position [C] of one where deflection is large.

Drive belt deflection (with 45 n, 4.6 kgf, 10 lb force):
- Standard: 1.5 - 4.0 mm (0.059 - 0.16 in.)
Drive belt deflection (with 45 N, 4.6 kgf, 10 lb force, when installing new belt or engine remounted):
- Standard: 1.5 mm (0.059 in.)
★ If the deflection is out of the specification, adjust it.
