NOTE: If the bolt is tightened first, the timing belt
B tensioner assembly should be turned together,
resulting in reduced timing belt B tensioner
assembly.

BELT/AUTO TENSIONER INSTALLATION
1. To reuse the auto tensioner, bleed the air

according to the procedure below, and then set
the rod to the auto tensioner.

CAUTION

• If a horizontal press such as a vice is used,

the air entrainment may occur. Thus, a verti-
cal press must be used.

• If the compression is too fast, the procedure

may damage the rod. Make sure to compress
slowly and thoroughly.

Auto tensioner

Press

Rod

To prevent a damage to the auto tensioner, do
not push down the rod exceeding the bottom
end (a position where the rod protrusion is at
0.5 mm from the auto tensioner).

(1) Set the auto tensioner to the vertical press,

and then slowly compress the rod to the
bottom end (a position where the rod
protrusion is at 0.5 mm from the auto
tensioner). Perform this operation 2 to 3 times.

(2) With the rod protruding (a position where the

rod protrusion is at 5 mm from the auto
tensioner), check that there is a rigidity when
the rod is pushed with a load (100 to 200 N).

(3) If the rod rigidity is not obtained by repeating

the operations of (1) and (2), replace the auto
tensioner.

(5) Insert a wire or pin in the aligned set hole.

NOTE: When the auto tensioner is replaced
with a new part, the auto tensioner is set with a
pin.

2. Install the auto tensioner in position. Leave the

wire or pin installed until the auto tensioner is
completely installed.

3. Install the tensioner arm assembly.

NOTE: When installing the timing belt into the
crankshaft sprocket, slide the crankshaft sprocket
to near the tip of the key, and then install the tim-
ing belt. (When installing the timing belt, be care-
ful not to damage the belt by the cut-out of
crankshaft sprocket.) After that, install the crank-
shaft sprocket to the correct position.

6. Check that the timing marks on sprockets are at

the correct positions.
