TIMING CHAIN ASSEMBLY

11) Remove chain guide. (Center)

12) Remove idler sprocket. (Upper)

13) Remove timing chain (LH).
14) Remove idler sprocket. (Lower)

B: INSTALLATION

NOTE:
• During installation, be careful to prevent foreign
objects from attaching to or mixing with assembled
components.
• Apply engine oil to chain guide, chain tensioner
lever, and idler sprocket during installation.
1) Preparation for installation of chain tensioner.

(1) Put the screw, spring, pin and tension rod
into the tensioner body.
(2) While pressing tensioner onto rubber mat,
twist it left and right to shorten tension rod. Then
set a thin pin into the holes between tension rod
and tensioner body to hold it.

NOTE:
Carry out the work on rubber mat or other nonslip
material.

2) Using ST, align “top mark” on crankshaft sprock-
et at 9 o'clock position as shown in the figure.

4) Rotate crankshaft sprocket clockwise to align
“top mark” at 12 o'clock position as shown in the fig-
ure. (Piston # 1 is at TDC.)

NOTE:
Do not rotate crankshaft and camshaft sprockets
until timing chain is completely routed. 

5) Install the idler sprocket. (Lower)

Tightening torque:

69 N·m (7.0 kgf-m, 50.6 ft-lb)

6) Install timing chain LH.

(1) Align the timing mark (B) on crankshaft
sprocket with the matching mark (A) on timing
chain LH.

(2) Route timing chain LH on idler sprocket
(Lower), water pump, exhaust cam sprocket,
and intake cam sprocket in order.

NOTE:
Make sure that matching marks on the timing chain
(A) and camshaft sprocket (B) are aligned the
same way as the one on crankshaft sprocket.

(3) Install chain idler. (Upper)
