- Measure the clearance between the control shaft bearing cap and the end of control shaft using a clearance gauge.
Clearance : 0.0 - 0.05 mm (0.0 - 0.002 in.)
- Install the intake OCV & center bolt (A).
Tightening torque : 22.6 - 26.5 N.m (2.3 - 2.7 kgf.m, 16.6 - 19.5 lb-ft) + 32 - 36º
WARNING
- To prevent impurities from entering intake oil control valve (OCV) & center bolt, wear rubber gloves.
- Intake oil control valve (OCV) and center bolt, hold the hexagonal portion on the camshaft with a wrench to prevent the camshaft from rotating.
- Compress the timing chain tensioner piston.
(1) With a pry bar (A), compress the timing chain tensioner piston (B).
(2) With a thin gimlet (A), raise the ratchet plate (B) of the timing chain tensioner and fix the piston.
WARNING
Do not remove the pick (A).
- Install the front bearing cap and camshaft bearing cap
WARNING
If there is enough engine oil on the camshaft front bearing cap and camshaft bearing cap installing bolt and bolt hole, tighten to the minimum required tightening torque.
Apply engine oil the upper part of the intake / exhaust camshaft journal, then install the camshaft front bearing cap and camshaft bearing cap. The amount of application should be enough to flow down both the front and back sides when it is applied to the center.
(1) Install the front bearing cap (A) and intake camshaft bearing cap (B).
- Remove the fine gimlets (A) that hold the timing chain tensioner.
- When installing the timing chain, be sure that the timing mark (A) of each sprocket is matched with the timing mark (B) (color link) of the timing chain.
