- Check timing mark on crankshaft as shown in the figure.
- Check timing mark on idler sprocket No. 2 (1) as shown in the figure.
- Install timing chain guide No. 4 (1).
Tightening torque
Timing chain guide No. 4 bolt (a): 11 N.m (1.1 kg-m, 8.0 lb-ft)
- Check that knock-pins of intake and exhaust camshafts are aligned with match marks on cylinder head as shown in the figure.
- Install by aligning match marks (2) on yellow plate (1) of LH bank 2nd timing chain and idler sprocket No. 2.
- Install sprockets to intake and exhaust camshafts by aligning silver plate (1) of LH bank 2nd timing chain, match marks on intake sprocket and exhaust sprocket respectively.CAUTION: Do not turn camshaft more than necessary. If turned excessively, valve and piston may get damaged.
- Install LH bank intake and exhaust camshaft timing sprockets.
To install it, fit a spanner to hexagonal part at the center of camshaft to hold stationary.
Tightening torque
Camshaft timing sprocket bolt (b): 80 N.m (8.0 kg-m, 58.0 lb-ft)
- With latch (2) of tensioner adjuster No. 3 returned and plunger (1) pushed back into body, insert stopper (pin) (4) into set hole (3).
After inserting it, check to make sure that plunger will not come out.
- Install timing chain tensioner adjuster No. 3 (1) in tightening order below.
Tightening torque
Timing chain tensioner adjuster No. 3 bolt (c): Tighten 11 N. m (1.1 kg-m, 7.5 lb-ft) by the specified procedure
Timing chain tensioner adjuster No. 3 nut (d): Tighten 55 N. m (5.5 kg-m, 40.0 lb-ft) by the specified procedure
Tightening order for tensioner bolt and nuts: "1" -->"2" -->"3"
- Pull out stopper (pin) (2) from set hole.
