NOTE:
Adjust valve clearance while engine is cold.
+Remove the adjusting shim for parts which are outside the
speci®ed valve clearance.
1. Remove the spill tube. Refer to ªBASIC SERVICE PROCE-
DUREº in EC section.
2. Rotate the crankshaft to face the cam nose for adjusting shims
that are to be removed upward.
3. Thoroughly wipe off engine oil on the upper side of the cylinder
head (for the air gun used in step 7).
4. Move the round hole of the adjusting shim to the front with an
extra-®ne screwdriver or like that.
CAUTION:
Perform (the above procedure) while camshaft do not contact
with adjusting shim.
5. Grip the camshaft with camshaft pliers (SST), then using the
camshaft as a support point, push the adjusting shim downward
to compress the valve spring.
CAUTION:
Do not damage the camshaft, cylinder head, and the outer cir-
cumference of the valve lifter.
6. With the valve spring in a compressed state, remove the cam-
shaft pliers (SST) by securely setting the outer circumference
of the valve lifter with the end of the lifter stopper (SST).
+Hold the lifter stopper by hand until the shim is removed.
CAUTION:
Do not retrieve the camshaft pliers forcefully, as the camshaft
will be damaged.
7. Remove the adjusting shim from the valve lifter by blowing air
through the round hole of the adjusting shim with an air gun.
CAUTION:
+When blowing, use goggles to protect your eye.
+To prevent any remaining oil from being blown around,
thoroughly wipe the area clean.

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.
