7. INSTALL CRANKSHAFT PULLEY
(a) Align the pulley’set key with the key groove of the
pulley.
(b) Install the pulley.
(c) Using SST to hold the crankshaft pulley, install and
torque the pulley bolt. .
SST MA 09213-70010 and 09330-00021
MS 092 13-54014 and 09330-00021
Torque: 2,700 kg-cm (195 ft-lb, 265 N-m) 8.
SET NO.1 CYLINDER TO TDC/COMPRESSION OF
CRANKSHAFT
Turn the crankshaft pulley and align its groove with the
“0” mark on the No.1 timing belt cover.
9. INSTALL CAMSHAFT TIMING PULLEYS
(a) Align the timing pulley matchmark with the No.2 tim-
ing belt cover matchmark.
(b) Install the timing pulley.
(c) Install the pin into the middle hole.
NOTE:
l When replacing the camshaft or the camshaft timing
pulley:
Align the center holes of the camshaft and timing
pulleys, as shown in the illustration and insert the
straight pin.
l When reusing the camshaft or camshaft timing pulleys:
Check that the straight pin hole position is in the same
position it was at disassembly, insert the straight pin.
(d) Install the pulley bolt.
(e) Using SST to hold the pulley, torque the pulley bolt.
SST 09278-54012
Torque: 500 kg-cm (36 ft-lb, 49 N-m)
(f) Check that the matchmarks on the camshaft timing
pulley are aligned with those on the No.2 timing belt
cover.
