12. Remove the timing chain tension guide (2) and the timing chain
slack guide (1).
13. Remove the timing chain (2). • Pull the looseness of timing chain toward the camshaft
sprocket (EXH) (1), and then remove the timing chain (2) and
start the removal from camshaft sprocket (EXH) (1) side.
CAUTION:
Never rotate crankshaft or camshaft while timing chain is
removed. It causes interferen ce between valve and piston.
14. Remove the crankshaft sprocket and the oil pump drive related parts with the following procedure.
a. Remove chain tensioner (1). • Pull out from the shaft (B) and spring fixing holes (A).
b. Hold the top of the oil pump s haft using the TORX socket (size:
E8), and then loosen the oil pump sprocket nut and remove it.
c. Remove the crankshaft sprocket (1), the oil pump drive chain (2), and the oil pump sprocket (3) at the same time.

The illustration shows the relationship between the matching mark
on each timing chain and that on the corresponding sprocket, with
the components installed.
1. Install the crankshaft sprocket and the oil pump drive related parts with the following procedure:
a. Install the crankshaft sprocket (1), the oil pump drive chain (2),
and the oil pump sprocket (3) at the same time.
• Install the crankshaft sprocket (1) so that its invalid gear area(A) is towards the back of the engine.
• Install the oil pump sprocket (3) so that its hexagonal surface
faces (B) the front of engine.
NOTE:
There is no matching mark in the oil pump drive related parts.
b. Hold the top of the oil pump shaft using the TORX socket (size: E8), and then tighten the oil pump sprocket nuts.

CAUTION:
Dimension L1 of journal No. 3 is the distance from the housing base end
surface (bulk) (not the
distance from the thrust bearing mounting end surface).
4. Install signal plate to crankshaft if removed.
a. Set the signal plate (1) with the flange facing toward the counter- weight side (engine front side) to the crankshaft rear surface.
b. After positioning crankshaft and signal plate with positioning dowel pin, tighten bolt.
NOTE:
Dowel pin of crankshaft and signal plate is provided as a set for
each.
c. Remove dowel pin. CAUTION:
Be sure to remove dowel pin.
5. Install crankshaft to cylinder block. • Make sure that crankshaft turns smoothly by hand.
CAUTION:
Never install rear oil seal yet.
6. Install main bearing caps in their original positions. • Install the main bearing cap while referring to the front mark(B) and the journal number stamp (A).
NOTE:
Main bearing cap cannot be replaced as a single part,
because it is machined together with cylinder block.
7. Tighten main bearing cap bolts in numerical order shown with the following steps.
a. Apply new engine oil to threads and seat surfaces of the bolts.
b. Tighten main bearing cap bolts in the numerical order shown.

18. Install knock sensor (1).
• Install connectors so that they are positioned towards the rearof the engine.
CAUTION:
• Never tighten bolt while holding the connector.
• If any impact by dropping is applied to knock sensor,
replace it with a new one.
NOTE:
• Make sure that there is no foreign material on the cylinder
block mating surface and the back surface of knock sensor.
• Make sure that knock sensor does not interfere with other parts.
19. Install crankshaft position sensor (POS) and cover. • Tighten bolts with it seated completely.
20. For the oil level gauge guide (1), fix the position (B) shown to the water inlet clip (A) after inserting to the cylinder block side.
21. Assembly is in the reverse order of disassembly after this step.

CRANKSHAFT END PLAY
• Measure the clearance between thrust bearings and crankshaft arm when crankshaft is moved fully forward or backward with a dial
indicator (A).
• If the measured value exceeds the limit, replace thrust bearings, and measure again. If it still exceeds the limit, replace crankshaft
also.
CONNECTING ROD SIDE CLEARANCE
• Measure the side clearance between connecting rod and crank-shaft arm with a feeler gauge (A).
• If the measured value exceeds the limit, replace connecting rod, and measure again. If it still exceeds the standard, replace crank-
shaft also.

TIMING CHAIN
21. Press stopper tab (A) in the direction shown to push the timing
chain slack guide (B) toward timing chain tensioner (for oil
pump) (1).
• The slack guide (B) is released by pressing the stopper tab(A). As a result, the slack guide (B) can be moved.
22. Insert stopper pin (D) into tensioner body hole (C) to secure tim- ing chain slack guide (B).
NOTE:
Use a hard metal pin with a diameter of approximately 1.2 mm
(0.047 in) as a stopper pin.
23. Remove timing chain tensioner (for oil pump), if necessary.
24. Hold the WAF part of oil pump shaft (A), and t hen loosen the oil pump sprocket bolt and remove them.
CAUTION:
• Secure the oil pump shaft with the WAF part (A).
• Never loosen the oil pump sp rocket bolt by tightening the
oil pump drive chain.
25. Remove crankshaft sprocket, oil pump sprocket and oil pump drive chain as a set, if necessary.
26. Remove timing chain tension guide (front co ver side) from front cover, if necessary.
