(2) Turn camshaft until arrows on hub are inline
with No. 1 camshaft cap to cylinder headline. Small
hole (arrow Fig. 12) must be in vertical center line. (3) Install timing belt.
(4) Rotate crankshaft two full revolutions and re-
check timing.
CAUTION: Do not allow oil or solvents to contact
the timing belt as they can deteriorate the rubber
and cause tooth skipping.
(5) Rotate crankshaft till number 1 cylinder is at
the TDC position. (6) Put belt tension Special Tool C-4703 horizon-
tally on large hex of timing belt tensioner pulley and
loosen tensioner lock nut. (7) Reset belt tension Special Tool C-4703 index if
necessary to have axis within 15É of horizontal. (Fig.
13) (8) Turn engine clockwise from TDC two crank revo-
lutions to TDC. Do not reverse rotate crankshaft
or attempt to rotate engine using cam or acces-
sory shaft attaching screw. (9) Hold weighted wrench in position while tighten-
ing bolt on tensioner to 61 N Im (45 ft. lbs.) torque.
(10) Lower engine onto engine mount install mount-
ing bolts and tighten to specifications refer to (Fig. 3). (11) Remove jack from under engine.
(12) Inspect foam stuffer block condition and posi-
tion (Fig. 14). Stuffer block should be intact and secure
within the engine bracket tunnel. (13) Position both halves of timing belt cover to-
gether (Fig. 4). (14) Install fasteners holding cover to cylinder head
and block. Tighten fasteners to 4 N Im (40 in. lbs.)
torque. (15) Valve Timing Check; (timing belt cover in-
stalled). With number one cylinder at TDC, small hole
in sprocket must be centered in timing belt cover hole
(Fig. 12). If hole is not aligned correctly perform
procedure again. (16) Install spark plugs.

(16) Connect the battery ground (negative) cable.
Test the operation of the lights and horns. If applica-
ble, reset the clock and radio.
STEERING COLUMN COMPONENT SERVICE
The Acustar tilt and standard steering columns
(Fig.1) have been designed to be serviced as an as-
sembly; less wiring, switches, shrouds, steering
wheel, etc. Also most steering column components
can be serviced without removing the steering col-
umn from the vehicle. For additional information on
electrical components refer to Group 8H Electrical.
GEAR SHIFT LEVER
The gear shift lever (if equipped) is a serviceable
component of the Acustar steering column assembly.
REMOVE (1) Support the steering column assembly as
shown in (Fig. 1) using a suitable size socket. (2) Using a drift of the appropriate size drive the
roll pin out of the steering column and gear shift le-
ver (Fig. 1). Remove the gear shift lever from the
steering column assembly.
INSTALL (1) Support the steering column assembly as
shown in (Fig. 1) using a suitable size socket. (2) Install the gear shift lever into the steering col-
umn assembly. Align the roll pin holes in the gear
shift lever and the steering column assembly. (3) Carefully Install the roll pin into the steering
column assembly and through the shift lever. If the
roll pin binds check the alignment on the holes. Be
sure roll pin is fully installed into the steering col-
umn assembly.
IGNITION SWITCH SERVICE
TEST AND REPAIR
If the ignition switch effort seems to be excessive
due to binding. Follow the procedure outlined below
to determine the cause.
When service procedures are performed on the
Acustar steering column there are certain areas of the
column that can not be tampered with. If a problem re-
lated to these areas of the steering column are detected.
The entire steering column (less the removable compo-
nents) should be replaced see (Fig. 2 and 3).
(1) Remove ignition switch from steering column.
Refer to Group 8H Electrical.
(2) Using a key cylinder, check the turning effort
of the switch.
² If the ignition switch binds look for the following
conditions.
