Chrysler New Yorker. Manual — part 212
NOTE: To reset the primary timing chain tensioner,
oil will first need to be purged from the tensioner
(Fig. 57).
(11) Purge oil from timing chain tensioner using
the following procedure:
a.
Remove the tensioner from tensioner housing
(Fig. 56).
b.
Place the check ball end of tensioner into the
shallow end of Special Tool 8186 (Fig. 57).
c.
Using hand pressure, slowly depress tensioner
until oil is purged from cylinder.
d.
Reinstall the tensioner into tensioner housing.
(12) Reset timing chain tensioner using the follow-
ing procedure:
e. Position cylinder plunger into the deeper end of
Special Tool 8186 (Fig. 58).
f. Apply a downward force until tensioner is reset.
NOTE: If oil was not first purged from the ten-
sioner, use slight finger pressure to assist the cen-
ter
arm
of
Special
Tool
8186
to
unseat
the
tensioners check ball.
CAUTION: Ensure that the tensioner is properly
reset. The tensioner body must be bottom against
the top edge of Special Tool 8186. Failure to prop-
erly perform resetting procedure may cause ten-
sioner jamming.
(13) Install chain tensioner into the right cylinder
head (Fig. 53).
(14) Starting at the right cylinder bank, insert a
3/8” square drive extension with a breaker bar into
intake camshaft drive hub. Rotate camshaft until the
camshaft hub aligns to the camshaft sprocket and
damper attaching holes. Install the sprocket attach-
ing bolts and tighten to 28 N·m (250 in. lbs.) (Fig.
55).
(15) Turn the left side camshaft by inserting a 3/8”
square drive extension with a breaker bar into intake
camshaft drive hub and rotate camshaft until the
sprocket attaching bolts can be installed. Tighten
sprocket bolts to 28 N·m (250 in. lbs.) (Fig. 55).
(16) Rotate engine slightly clockwise to remove
timing chain slack, if necessary.
(17) To arm the timing chain tensioner: Use a flat
bladed pry tool to gently pry tensioner arm towards
the tensioner slightly (Fig. 59). Then, release the ten-
sioner arm. Verify the tensioner is armed (extends).
(18) Install the timing chain cover, crankshaft
damper, and cylinder head covers.
(19) Install camshaft position sensor and connect
electrical connector.
(20) Install upper intake manifold. Refer to Group
11, Exhaust System and Intake Manifold.
NOTE: After installation of a reset tensioner, engine
noise will occur after initial start-up. This noise will
normally disappear within 5 – 10 seconds.
CRANKSHAFT SPROCKET
REMOVAL
(1) Remove primary timing chain. Refer to proce-
dure outlined in this section.
CAUTION: Use care not to turn crankshaft while
removing crankshaft sprocket, as damage to valves
and or pistons could occur.
(2) Remove crankshaft sprocket by installing the
crankshaft damper bolt and using Special Tool 1023.
Remove sprocket using care not to rotate the crank-
shaft.
INSTALLATION
(1) Install crankshaft sprocket using Special Tools
6780-1 and 8179 (Fig. 61) until sprocket bottoms
against crankshaft step flange. Use care not to rotate
crankshaft.
(2) Verify that crankshaft sprocket is installed to
proper depth by measuring from sprocket outer face
to end of crankshaft (Fig. 62). Measurement should
read: 39.05
60.50 mm (1.5374 60.002 in.).
(3) Install primary timing chain. Refer to proce-
dure outlined in this section.

outlined in this section.
(2) Insert Special Tool 8194, into crankshaft nose.
Remove seal using Special Tool 6771, Remover (Fig.
63).
INSTALLATION
(1) Install new seal using Special Tools 6780–2

CRANKSHAFT OIL SEAL—REAR
REMOVAL
(1) Remove transaxle from vehicle. Refer to Group
21, Transaxle for procedure.
(2) Remove drive plate.
(3) Insert a 3/16” wide flat bladed screwdriver
between the dust lip and the metal case of the crank-
shaft seal. Angle the screwdriver (Fig. 65) through
the dust lip against the metal case of the seal. Pry
out seal.
CAUTION: Do not allow the screwdriver blade to
contact the crankshaft seal surface. Contact of the
screwdriver blade against crankshaft edge (cham-
fer) is permitted
INSTALLATION
CAUTION: If a burr or scratch is present on the
crankshaft edge (chamfer), clean surface using 400
grit sand paper to prevent seal damage during
installation.
(1) Place Special Tool 6926-1 Guide on crankshaft
(Fig. 66). This is a pilot tool with a magnetic base.
(2) Position seal over pilot tool. Assure that lip of
seal is facing towards the crankshaft during installa-
tion. The pilot tool remains on crankshaft during seal
installation.
(3) Using Special Tool 6926-2 Installer, and C-4171
Handle (Fig. 66), drive seal into the retainer housing
until seal is flush with housing surface.
(4) Install drive plate and transaxle.
CRANKSHAFT OIL SEAL RETAINER—REAR
REMOVAL
(1) Remove crankshaft rear oil seal and oil pan.
Refer to procedure outlined in this section.

retainer against Special Tools 8225 (Fig. 68), tighten
seal retainer screws to 12 N·m (105 in. lbs.)
(5) Install crankshaft rear oil seal. Refer to proce-
dure outlined in this section.
OIL PAN
REMOVAL
(1) Remove dipstick and housing.
(2) Raise vehicle on hoist.
(3) Drain engine oil and remove oil filter.
(4) Remove structural collar from oil pan to trans-
mission housing (Fig. 70).
CAUTION: Assure removal of the two bolts attach-
ing the timing cover to the oil pan, as damage to
the timing cover and/or oil pan may occur.
(5) Remove oil pan attaching fasteners. Remove oil
pan and gasket (Fig. 69).
INSTALLATION
(1) Clean oil pan and sealing surfaces. Inspect oil
pan and timing chain cover gaskets and replace as
necessary.

t Silicone Rub-
ber Adhesive Sealant to the front T-Joints (oil pan
gasket to timing cover gasket interface) (Fig. 69).
