TIMING BELT AND SPROCKETS (Continued)
CLEANING
Do Not attempt to clean a timing belt. If contami-
nation from oil, grease, or coolants have occurred, the
timing belt should be replaced.
Clean all sprockets using a suitable solvent. Clean
all sprocket grooves of any debris.
INSTALLATION
INSTALLATION - CRANKSHAFT SPROCKET
CAUTION: The crankshaft sprocket is set to a pre-
determined depth from the factory for correct tim-
ing belt tracking. If removed, use of Special Tool
6792 is required to set the sprocket to original
installation depth. An incorrectly installed sprocket
will result in timing belt and engine damage.
(1) Install crankshaft sprocket using Special Tool
6792 (Fig. 143).

(2) Install timing belt (Refer to 9 - ENGINE/
VALVE TIMING/TIMING BELT AND SPROCKETS -
INSTALLATION).
(3) Connect negative battery cable.
INSTALLATION - CAMSHAFT SPROCKETS
(1) Install camshaft sprockets. Hold camshaft
sprockets with Special Tools C-4687 and Adaptor
C-4687-1 while tightening center bolts to 115 N·m (85
ft. lbs.) (Fig. 141).
(2) Install timing belt (Refer to 9 - ENGINE/

2 - CENTERLINE
(3) Rotate crankshaft 1/2 tooth counterclockwise
from TDC (Fig. 146).
(4) Install the timing belt. Starting at the crank-
shaft, go around the water pump sprocket, idler pul-
ley, camshaft sprockets, and finally route the back
side of the timing belt around the timing belt ten-
sioner pulley.
(5) Move crankshaft sprocket to TDC to take up
belt slack.
(6) Insert a 6 mm Allen wrench into the hexagon
opening located on the top plate of the belt tensioner
