REMOVAL
CAUTION:
• After removing timing chain, do not turn the crankshaft and camshaft separately, or the valves will
strike the pistons.
• When installing camshafts, chain tensioners, oil seal s, or other sliding parts, lubricate contacting
surfaces with new engine oil.
• Apply new engine oil to bolt threads and seat su rfaces when installing camshaft sprockets, camshaft
brackets, and crankshaft pulley.
• Before disconnecting fuel hose, release fuel pressure. Refer to FL-5, "Inspection"

REAR TIMING CHAIN CASE
• Before removing the upper oil pan, re
move the crankshaft position sensor (POS).
• Be careful not to damage sensor edges.
• Do not spill engine oil or coolant on drive belt.
1. Remove the engine assembly. Refer to EM-220, "Removal and Installation"
.
2. Remove the oil pan lower and upper. Refer to EM-157, "Removal and Installation (Upper Oil Pan)"
.
3. Remove the front timing chain case. Refer to EM-174, "Removal and Installation"
.
4. Remove the primary and secondary timing chains. Refer to EM-182, "Removal and Installation"
.
5. Remove the rear timing chain case. CAUTION:
• Do not remove the plate metal cover for the oil passage.
• After removing the chain case, do not apply any load to
the case that might bend it.
a. Loosen and remove the rear timing chain case bolts in the order as shown.
b. Cut the sealant using Tool (A) and remove the rear timing chain case.
CAUTION:
• Be careful not to damage the mating surface.
• Do not insert a screwdriver or similar tool, this will dam-
age the mating surfaces.
c. In areas where the cutter is difficult to use, use a plastic hammer to lightly tap (1) the cutter where the liquid gasket is applied. Use
a plastic hammer to slide (2) the cutter by tapping on the side.

INSPECTION AFTER REMOVAL
Camshaft Visual Check
Check camshaft for scratches, seizure and wear. Replace if necessary.
Camshaft Runout
1. Put V-block on precise flat bed and support No. 2 and No. 4 jour-
nal of camshaft as shown.
2. Set dial gauges vertically to No. 3 journal as shown.
3. Turn camshaft in one direction slowly by hand, measure the camshaft runout on the dial gauges.
• Runout is the largest indicator reading after one full revolution.
4. If actual runout exceeds th e limit, replace the camshaft.
