ASSEMBLY
1) Wash, clean and then dry all disassembled parts.
2) Apply thin coat of engine oil to inner and outer rotors, oil seal
lip portion, and inside surfaces of oil pump case and plate.
3) Install outer (1) and inner rotors (2) to oil pump case.
4) Install relief valve component (1) to rotor plate (2).
5) Install rotor plate and tighten all bolts to specified torque.
After installing plate, check to be sure that rotors turn
smoothly by hand (0.3 N·m (0.03 kg-m, 0.25 lb-ft) torque or
below).
Tightening torque
Oil pump rotor plate bolts (a) : 11 N·m (1.1 kg-m, 8.0 lb-ft)
INSTALLATION
For installation referring to “TIMING CHAIN COVER”.

ENGINE MECHANICAL (M13 ENGINE) 6A1-35
INSPECTION
Timing chain tensioner
Check shoe (1) for wear or damage.
Crankshaft timing sprocket
Check teeth of sprocket for wear or damage.
Timing chain
Check timing chain for wear or damage.
Timing chain tensioner adjuster
Check that tooth surface (1) are free from damage.

6A1-36 ENGINE MECHANICAL (M13 ENGINE)
Timing chain No.1 guide
Check shoe (1) for wear or damage.
INSTALLATION
1) Check that match marks (1) on intake and exhaust camshaft
timing sprockets are in match with notches (2) on cylinder
head as shown in figure.
2) Set key (3) and turn crankshaft to position key on upside of
crankshaft.
3) Install timing chain by aligning dark blue plate (1) of timing
chain and triangle mark (2) on camshaft timing sprocket as
shown in figure.
4) Fit crankshaft timing sprocket to timing chain by aligning gold
plate (3) of timing chain and mark (4) on crankshaft timing
sprocket. Then install crankshaft timing sprocket fitted with
chain to crankshaft.
CAUTION:
After timing chain is removed, never turn crankshaft and
camshafts independently more than such an extent (“a”,
“b”) as shown in figure.
If turned, interference may occur between piston and
valves and valves themselves, and parts related to piston
and valves may be damaged.
“a” :90°4. Camshaft (IN and EX) allowable turning range.
By marks on camshaft timing sprocket within 15° from notches on
cylinder head on both right and left.
“b” :15°5. Crankshaft allowable turning range.
By key on crankshaft, within 90° from top on both right and left.

5) Apply engine oil to sliding surface of timing chain No.1 guide
(1) and install it as shown in figure.
Tighten guide bolts to specified torque.
Tightening torque
Timing chain No.1 guide bolt
(a) : 9 N·m (0.9 kg-m, 6.5 lb-ft)
6) Apply engine oil to sliding surface of chain tensioner (1) and
install chain tensioner and spacer.
Tighten tensioner bolt to specified torque
Tightening torque
Timing chain tensioner bolt
(a) : 22 N·m (2.2 kg-m, 16.0 lb-ft)
7) Check that match marks (1) on intake and exhaust camshaft
timing sprockets are in match with making timing chain (2)
and match mark on crankshaft timing sprocket (3) are in with
marking timing chain(4).
8) Screw in plunger (1) by turning body (2) in arrow direction
and install a retainer (3) (wire) to hold plunger in place.

9) Install timing chain tensioner adjuster assembly (1) with a
retainer (2).
Tighten adjuster bolts to specified torque and then remove a
retainer from chain tensioner adjuster assembly.
Tightening torque
Timing chain tensioner adjuster bolts
(a) : 11 N·m (1.1 kg-m, 8.0 lb-ft)
10) Apply engine oil to timing chain and then turn crankshaft
clockwise by 2 revolutions and check that match marks (1)
on intake and exhaust camshaft timing sprockets are in
match with notches (2) on cylinder head and key (3) is on
upside of crankshaft as shown in figure.
If each marking chain and each match mark are no matches,
adjust each sprockets and timing chain.
11) Install timing chain cover referring to “TIMING CHAIN
COVER”.
12) Install cylinder head cover referring to “CYLINDER HEAD
COVER”.
13) Install oil pan referring to “OIL PAN AND OIL PUMP
STRAINER”.
14) Adjust water pump belt tension referring to Section 6B.
15) Adjust A/C compressor belt tension (if equipped) referring to
Section 1B.
16) Refill engine with engine oil.
17) Verify that there is no oil leakage and exhaust gas leakage at
each connection.

7) Remove tappets (2) with shims (1).
INSPECTION
Cam Wear
Using a micrometer, measure cam height “a”. If measured height
is below its limit, replace camshaft.
Cam height “a” of camshaft
Camshaft Runout
Set camshaft between two “V” blocks, and measure its runout by
using a dial gauge.
If measured runout exceeds below limit, replace camshaft.
Camshaft runout limit
: 0.10 mm (0.0039 in.)
Camshaft Journal Wear
Check camshaft journals and camshaft housings for pitting,
scratches, wear or damage.
If any malcondition is found, replace camshaft or cylinder head
with housing. Never replace cylinder head without replacing hous-
ings.
Check clearance by using gaging plastic. Checking procedure is
as follows.
1) Clean housings and camshaft journals.
2) Remove all tappets with shims.
3) Install camshafts to cylinder head.
4) Place a piece of gaging plastic to full width of journal of cam-
shaft (parallel to camshaft).
5) Install camshaft housing.
