Suzuki Grand Vitara JB627. Manual — part 86

1D-25 Engine Mechanical:

Installation

1) Check timing mark on crankshaft as shown in figure.

2) Check timing mark on idler sprocket No.2 (1) as

shown in figure.

3) Install timing chain guide No.4 (1).

Tightening torque
Timing chain guide No.4 bolt (a): 11 N·m (1.1
kgf-m, 8.0 lb-ft)

4) Check that knock-pins of intake and exhaust

camshafts are aligned with match marks on cylinder
head as shown in figure.

5) Install by aligning match marks (2) on yellow plate

(1) of LH (No.1) bank 2nd timing chain and idler
sprocket No.2.

6) Install sprockets to intake and exhaust camshafts by

aligning silver plate (1) of LH (No.1) bank 2nd timing
chain, match marks on intake sprocket and exhaust
sprocket respectively.
