TENSIONER PULLEY
GENTE
8.24 Make sure the tension side of the belt is drawn tight when
initially installing the timing belt - also, the tensioner pulley must
be positioned as shown
8.25a Rotate the tensioner clockwise and up to apply tension
to the belt
8.29 Since you must view the camshaft sprocket marks at an
angle, it may help to use a pointer to avoid mistakes
cy/inderb/ock(see illustration 8.15). Make sure the screwdriverextends
approximately two inches into the hole and also make sure the sprocket
cannot be rotated with the screwdriver in place; now you can be sure the
timing is correct.
23 install timing belt B. Align the timing marks on each sprocket with the
timing marks on the front case (see illustration).

8.2513 Press on the center of the belt to check tension
24 After installing timing belt B, make sure the tension side has no slack
(see illustration).
25 Make sure the tensioner sprocket for timing belt 6 has the center lo-
cated just to the left side of the mounting bolt with the pulley directed to the
front of the engine (see illustration 8.24). Lift the tensioner up with one
fingerto tighten the belt (see illustration) and tighten the tensioner bolt to
the torque listed in this Chapter’s Specifications. Note: Use the index fin-
gerandpress fimty on the timing be/t(see illustration). The belt deflec-
tion should be 1364 to 9/32-inch (5.0 to 7.0 mm).
26
Slip the timing belt onto the crankshaft sprocket. While maintaining
tension on the rear (firewall) side of the belt, slip the belt onto the camshaft
sprocket.
27
Release the tensioner hold-down bolt to apply spring tension against
the belt. Retighten the bolt.
28 Install the crankshaft pulley, taking care to align the locating pin with
the small hole in the pulley (if equipped). Install the crankshaft pulley bolts
(both the pulley securing bolts and the center bolt) and tighten them to the
torques listed in this Chapter’s Specifications. When tightening the bolts,
hold the crankshaft in place using one of the methods discussed in Steps
11 and 12.
29 Using the bolt in the center of the crankshaft pulley, turn the crank-
shaft clockwise through sixcomplete revolutions. Note: The camshaft,
crankshaftand right Silent Shaftsprocketmarks willalign every two revo-
lutions of the crankshaft; however, since the left (oilpump) sprocket turns
at2/3crankshaftspeed, itsmarks willonlyatigneverysixcrankshaft revo-
lutions. Recheck the alignment of the timing marks (see illustration). If
the marks do not align properly, loosen the tensioner; slip the belt off the
camshaft sprocket, align the marks, reinstall the belt, and check the align-
ment marks again.
