2008 INFINITI FX35 remove seats

ATC-6
< SERVICE INFORMATION >
PRECAUTIONS
 Garter spring cannot be removed from cage of male-side piping.
 Indicator ring remains near piping connection point, however, this is not a malfunction. (This is to check pip-
ing connection during factory assembly.)
REMOVAL
1. Clean piping connection point, and set a disconnector.
2. Slide disconnector in axial direction of piping, and stretch garter spring with tapered point of disconnector.
3. Slide disconnector farther so that inside diameter of garter spring becomes larger than outside diameter of
female-side piping flare. Then male-side piping can be disconnected.
INSTALLATION
1. Clean piping connection points, and insert male-side piping into female-side piping.
2. Push inserted male-side piping harder so that female-side piping flare stretches garter spring.
3. If inside diameter of garter spring becomes larger t han outside diameter of female-side piping flare, garter
spring seats on flare. Then, it fits in between male-side piping cage and female-side piping flare to anchor
piping connection point.
NOTE:
When garter spring seats on flare, and fits in betw een male-side piping cage and female-side piping flare,
it clicks.
CAUTION:
 Female-side piping connection is thin and easy to deform. Slowly insert the male-side piping
straight in axial direction.
 Insert piping securely until a click is heard.
 After piping connection is comple ted, pull male-side piping by hand to make sure that connec-
tion does not come loose.
NOTE: One-touch joint connection is used in points below.

TIMING CHAIN
Do not overtighten slack guide
mounting bolts. It is normal
for a gap to exist under the bo lt seats when mounting bolts
are tightened to the specification.
9. Install the timing chain tensioner (primary) with the following procedure:
a. Pull plunger stopper tab up (or turn lever downward) so as to remove plunger stopper tab from the rachet of plunger.
NOTE:
Plunger stopper tab and lever are synchronized.
b. Push plunger into the inside of tensioner body.
c. Hold plunger in the fully compressed position by engaging plunger stopper tab with the tip of ratchet.
d. To secure lever, insert stopper pin through hole of lever into ten- sioner body hole.
 The lever parts and the tab are synchronized. Therefore, theplunger will be secured under this condition.
NOTE:
Figure shows the example of 1.2 mm (0.047 in) diamet er thin screwdriver being used as the stopper pin.
e. Install timing chain tensioner (primary).  Remove any dirt and foreign materials completely from theback and the mounting surfaces of timing chain tensioner (pri-
mary).
f. Pull out stopper pin after installing, and then release plunger.
10. Make sure again that the mating marks on sprockets and timing chain have not slipped out of alignment.
11. Install new O-rings on rear timing chain case.
12. Install new front oil seal on front timing chain case.  Apply new engine oil to both oil seal lip and dust seal lip.

VALVE SEAT REPLACEMENT
When valve seat is removed, replace with
oversized [0.5 mm (0.020 in)] valve seat.
1. Bore out old seat until it collapses. Boring shoul d not continue beyond the bottom face of the seat recess
in cylinder head. Set the machine depth stop to ensure this. Refer to EM-266, "
Standard and Limit".
CAUTION:
Prevent to scratch cylinder head by excessive boring.
2. Ream cylinder head recess diameter for service valve seat.
 Be sure to ream in circles concentric to valve guide center.This will enable valve to fit correctly.
3. Heat cylinder head to 110 to 130 °C (230 to 266 °F) by soaking in
heated oil.
4. Provide valve seats cooled well with dry ice. Force fit valve seat into cylinder head. CAUTION:
 Avoid directly touching cold valve seats.
 Cylinder head contains heat. Wh en working, wear protective equipment to avoid getting burned.
5. Using valve seat cutter set (commercial service tool) or valve seat grinder, finish seat to the specified dimensions. Refer to
EM-266, "
Standard and Limit".
CAUTION:
When using valve seat cutter, firmly grip cutter handle with
both hands. Then, press on the contacting surface all
around the circumference to cu t in a single drive. Improper
pressure on with cutter or cu tting many different times may
result in stage valve seat.
6. Using compound, grind to adjust valve fitting.
7. Check again for normal contact. Refer to "VALVE SEAT CONTACT".
