(2) Place a torque wrench and socket on camshaft
sprocket attaching bolt and apply torque in direction of
crankshaft rotation to take up slack; 41 N
I
m (30 ft. lb.)
with cylinder head installed or 20 N
I
m (15 ft. lb.) with
cylinder heads removed. With a torque applied to
the camshaft sprocket bolt, crankshaft should
not be permitted to move. It may be necessary to
block crankshaft to prevent rotation.
(3) Holding a scale even, with dimension reading as
shown (Fig. 3 ), along edge of chain links. Apply torque
in the reverse direction to 41 N
I
m (30 ft. lbs.) with
cylinder heads installed, or 20 N
I
m (15 ft. lbs.) with
cylinder heads removed. Check amount of chain move-
ment (Fig. 3).
(4) Install a new timing chain, if its movement
exceeds 3.175mm (1/8 inch) (Fig. 3).
(5) If chain is not satisfactory, remove camshaft
sprocket attaching bolt, and remove timing chain with
camshaft sprocket.
(6) Using a suitable puller remove the crankshaft
sprocket. Be careful not to damage the crankshaft
surface.
(7) Position a new crankshaft sprocket on the
shaft, install sprocket with suitable tool and mallet.
Be sure sprocket is seated into position.
(8) Rotate crankshaft so the timing arrow is to the
12 O’clock position.
(9) Place timing chain around camshaft sprocket
and place the timing arrow to the 6 O’clock position.
(10) Align the dark colored links with the dot on
the camshaft sprocket, place timing chain around
crankshaft sprocket with the dark colored link lined
up with the dot on sprocket and install camshaft
sprocket into position.
(11) Using straight edge to check alignment of
timing arrows (Fig. 4).
(12) Install camshaft bolt and washer. Tighten to
54 N
I
m (40 ft. lbs.).
(13) Rotate crankshaft 2 revolutions. Timing ar-
rows should line up. If timing arrows do not line up
remove cam sprocket and realign.
(14) Check camshaft endplay. With new thrust
plate specification is .0127 to .304 mm (.005 to .012
inches.). Old thrust plate specification is .31 mm
(.012 inch.) maximum. If not within these limits in-
stall new thrust plate.
(15) Install timing chain snubber. Tighten retain-
ing screws to 12 N
I
m (105 in. lbs.).
INSTALLATION
(1) Be sure mating surfaces of chain case cover and
cylinder block are clean and free from burrs. Crank-
shaft oil seal must be removed to insure correct oil
pump engagement.
(2) Use a new cover gasket, O-rings. (Fig. 5).
(3) Rotate crankshaft so that the oil pump drive
flats are vertical.
(4) Position oil pump inner rotor so the mating
flats are in the same position as the crankshaft drive
flats (Fig. 5).
(5) Install cover onto crankshaft. Make sure the oil
pump is engaged on the crankshaft correctly or se-
vere damage may result.
