11.Remove control valve by rotating tool No. T10352, or equivalent in clockwise direction.
12.Remove bolts, then bearing bracket.
13.Press oil pump chain tensioner away from timing chain, and secure with lock pin tool No. T40011, or equivalent.
14.Remove oil pump chain tensioner guide pin.
15.Remove oil pump chain tensioner.
16.Lift chain tensioner locking wedge by inserting a suitable screwdriver into hole in chain tensioner and moving downward and secure with lock pin tool No. T40011, or equivalent.
17.Remove timing chain tensioning rail guide pin and tensioning rail.
18.Remove timing chain guide rail guide pins and guide rail.

c.Mount timing chain on crankshaft.
d.Turn intake camshaft counterclockwise using a suitable wrench and mount timing chain. Continue to hold camshaft with wrench.
e.Install timing chain tensioning rail and torque guide pin to 15 ft. lbs.
f.Install timing chain guide rail and tighten guide pins.
g.Install bearing bracket and tighten bolts hand tight.
h.Remove lock pin from chain tensioner.
i.Torque bearing bracket bolts M6 bolts to 72 inch lbs., then tighten bolt an additional 90°. Torque M8 bolts to 15 ft. lbs., then tighten bolt an additional 90°.
j.Torque lower timing chain cover attaching bolts in sequence illustrated in Fig. 2, to 79 inch lbs., then tighten bolts an additional 45°.
k.Torque upper timing chain cover bolts to 79 inch lbs.
l.Install accessory drive belt.
m.Inspect cooling system and fill to proper level with recommended coolant, as required.
