+When removing or installing hood, place a cloth or other padding on front fender panel and cowl top. This
prevents vehicle body from being scratched.
+Bumper fascia is made of plastic. Do not use excessive force and be sure to keep oil away from it.
+Hood adjustment: Adjust at hinge portion.
+Hood lock adjustment: After adjusting, check hood lock control operation. Apply a coat of grease to hood
locks engaging mechanism.
+Hood opener: Do not attempt to bend cable forcibly. Doing so increases effort required to unlock hood.

8. Remove the crankshaft pulley.
+To ®x the crankshaft, remove the starter motor, and set ring
gear stopper (SST).
CAUTION:
+Do not damage or magnetize the signal detection protru-
sions of the crankshaft pulley.
+After removing timing chain, never rotate crankshaft, or
the piston will push the valve up and damage the valve.
9. Remove the gear case.
+Using the grooved places shown in the ®gure, remove the gear
case by using a screwdriver and a seal cutter (SST).
10. Remove the front oil seal from the gear case by using a screw-
driver.
CAUTION:
Do not damage the gear case.
11. Fix the internal mechanism setting bolt [part No.: 81-20620-28,
screw dia.: M6, dimension below neck: 20 mm (0.79 in)] to the
bolt hole of the idler gear (A) and tighten to the speci®cation.
: 2.5 - 3.4 Nzm (0.25 - 0.35 kg-m, 22 - 30 in-lb)
CAUTION:
+Only use the genuine setting bolt, or the idler gear (A) will
be damaged.
+Do not rotate the crankshaft as the head of the setting
bolts interferes with the gear case.
+Do not remove the setting bolt from the idler gear (A) until
the timing chain and all of the parts in connection have
been installed.
+If these bolts are not installed, internal mechanism will
disengage after the idler gear is removed. This will prohibit
the idler gear from being reusable.
12. Remove the idler gears (A) and (B).
+Check the backlash of each gear before removing. Refer to
EM-52, ªBACKLASH OF EACH GEARº, ªInspectionº in
NISSAN Service Manual (Publication No. SM9E-Y61CG2 or
SM9E-Y61CG3).
CAUTION:
+Do not loosen the internal mechanism setting bolt of the
idler gear (A). (The idler gear cannot be reused when the
internal mechanism is released.)
+During removal of the idler gears (A) and (B), do not face
the rear side downward as the idler shaft will drop.
