INSTALLATION SERVICE POINTS

A

TIMING BELT INSTALLATION

1.

Turn the crankshaft clockwise to align the crankshaft
groove with the center of the two ribs of the crankshaft
closure cover. Furthermore, confirm that the timing mark
of the crankshaft sprocket is a tooth off to the left of the
perpendicular shaft in the engine.

2.

Confirm that the timing mark of the camshaft sprocket
aligns with the center of the window of the timing belt
cover.

3.

Fit the timing belt so that the lines on the belt are aligned
with the marks on the crankshaft and camshaft sprockets.

4.

Place the bolt in the timing belt tensioner pulley to tighten
the bolt so that the timing belt tension becomes the
standard value.
Use the MUT-

II

to measure the timing belt tension.

Standard value: 90

±

15 Hz

THE MEASUREMENT METHOD OF TIMING BELT
TENSION

(1) Connect the special tool (MB991668) to the MUT-

II

.

(2) Connect the MUT-

II

to the diagnosis connector.

(3) Turn the ignition switch to the on position to select

“Belt tension measurement” in the menu.

(4) Place the microphone 10 to 20 mm behind the belt

located in the center between the camshaft sprocket
and the crankshaft sprocket and hole it perpendicular
to the belt (approximate inclination of

±

15

°

or less).
