should be at least at the bottom edge of fill hole,
when motor bracket is held on a level (flat) surface.
If low, inspect for leak in hydraulic system.

(5) Motor/Pump:

(a) Put reservoir fill plug back in place. Apply

power to the motor and listen for operation. If the
motor fails to run, check the voltage to the connec-
tor (10.5 to 16 volts required). Voltage below 12.6
volts will cause top to operate slowly.

(b) Check the motor/pump for evidence of fluid

leak. If leakage is seen and fittings/hoses and cyl-
inders don’t have any leaks, then replace the
motor/pump.
(6) Cylinders:

(a) Check cylinder tubes for dents.
(b) Check cylinders for leaks. Leaks are indi-

cated by hydraulic fluid running down the cylin-
ders. Small oil residue accumulation at seal is
normal.
(7) Repair or replace components, as necessary.
(8) Bleed the motor/pump (Refer to 23 - BODY/

CONVERTIBLE TOP - ADJUSTMENTS - HYDRAU-
LIC MOTOR/PUMP BLEEDING PROCEDURES).

(9) Secure motor/pump assembly into floor panel

mounts.

(10) Raise top.
(11) Lower top and verify fluid level per step three.

If low, add Dexron III Automatic Transmission Fluid
as necessary. Do not overfill reservoir.

(12) Install rear seat back and cushion making

sure these components do not cause hydraulic line
pinches and/or kinks.

(13) Verify system operation.

ADJUSTMENTS

ADJUSTMENT - CONVERTIBLE TOP

Refer to (Fig. 1) to determine which adjustment is

required. Refer to the appropriate procedure for more
information.

ADJUSTMENT - HYDRAULIC MOTOR/PUMP
BLEEDING PROCEDURES

After replacing any component of the power lift

mechanism or if convertible top does not start to
raise within 2 seconds after the switch is activated,
bleed the convertible top motor/pump assembly.

(1) Raise the top to the full up position. Do not

latch folding top.

(2) Remove the rear seat cushion, seat back and

quarter trim panels.

(3) Completely detach cylinders from attachment

points (mounting bracket nuts and pivot bolts attach-
ing cylinder shafts to top linkage). Cylinders will be
extended.

(4) Remove motor from floor panel. Keep motor

connected to wire harness.

(5) Hold cylinders upside down (cylinder rod point-

ing down).

(6) Hold motor/pump assembly with reservoir up.

The rubber fill plug will be at the top.

(7) Raise motor/pump assembly to at least 2 inches

above the horizontal rear seat back reinforcement.

(8) Cycle system at least once, making sure cylin-

ders can extend without obstruction. Allow for two to
three seconds stall. There may be a percolating or
gurgling sound, which indicates that the procedure is
working.

(9) Hold cylinders in normal position and cycle

system at lease once, making sure cylinders can
extend without obstruction. Allow for two to three

seconds stall. There may be a percolating or gurgling
sound, which indicates that the procedure is working.
At this point, any air in the system has migrated to
the reservoir.

(10) Retract cylinders completely and remove the

rubber fill plug from reservoir. Fluid level may be
low.

(11) Remove the rubber fill plug from reservoir.

Fluid level may be low.

CAUTION: THE MOTOR/PUMP ASSEMBLY MUST
REMAIN IN THE CURRENT POSITION UNTIL THE
RUBBER FILLER PLUG IS REINSTALLED.

(12) Fill the hydraulic system by adding Dexron

III Automatic Transmission Fluid to the reservoir.
The fluid level should be 13 to 20 mm (

⁄

inch)

below the top of the reservoir.

CAUTION: DO NOT OPERATE THE FOLDING TOP
SWITCH WHILE FILL PLUG IS NOT INSTALLED ON
MOTOR ASSEMBLY.

(13) Install rubber fill plug.
(14) Secure motor/pump assembly into floor panel

mounts. Extend cylinders.

(15) Place the cylinders into original position with

hose fittings pointing fitting rearward.

(16) Install pivot bolt attaching cylinder shaft to

top linkage. Torque properly. Ensure all rod eye com-
ponents are present (foam, plastic bushing and plas-
tic lock washer).

(17) Install cylinder mounting bracket and nut.

Torque properly. Ensure all trunnion split bushings
are present. Tap folding top switch to adjust cylinder
length, if needed.

WARNING:

HYDRAULIC

CYLINDERS

PRODUCE

ENOUGH FORCE TO PRODUCE SEVERE INJURY IN
CASE OF PUNCHING. KEEP HANDS AND FINGERS
AWAY FROM MOVING HYDRAULIC CYLINDERS.

(18) Install all hydraulic line clips and secure

hydraulic lines to body.

(19) Verify system operation.
(20) Install the quarter trim panels.
(21) Install rear seat back and cushion and ensure

that the seat back/seat cushion do not pinch or kick
the lines.

(22) Verify system operation.

ADJUSTMENT - TOP FRAME CAM

The top frame cam changes forward or rearward

position of the top header in relation to the wind-
shield header. The cam turns inside the rear side rail
and thrust link (Fig. 2). It may be necessary to
lengthen the balance links 1 or 2 serrations after a

cam adjustment. The position of the cam high side
determines the angle between the center and rear
side rails. When the high side is fully forward, the
angle is at a minimum, and when turned rearward,
the angle is increased. An increased angle increases
the forward movement of the top. The cam high side
is indicated by a arrow on the cam threaded end.

TO ADJUST CAM SETTING

(1) Lower top to half down position to remove all

possible strain from the cam.

(2) Remove Torx head screw.
(3) Using appropriate Torx bit, rotate cam as nec-

essary and secure set screw. Tighten Torx bit screw
to 5.2 to 7.2 N·m (43 to 67 in. lbs.) torque

ADJUSTMENT - BALANCE LINK

WARNING: DO NOT PLACE HANDS OVER GAPS IN
MOVABLE CONVERTIBLE TOP COMPONENTS DUR-
ING SERVICING. PERSONAL INJURY CAN RESULT.

(1) Remove quarter trim panel to gain access to

balance link bolts.

(2) With the top latched in up position, loosen both

bolts just enough to permit moving link up or down
(Fig. 3).

(3) Push upward in the area of the front to center

rail joint. Push rails up by hand as far as possible.

(4) With the balance link adjusting bolts loosened,

allow the balance link to seek proper position.

(5) Tighten top link bolt while rail is held in posi-

tion to 11.7 to 17.7 N·m (105 to 155 in. lbs.) torque.

(6) Tighten bottom link bolt while rail is held in

position to 22 to 32 N·m (192 to 288 in. lbs.) torque.
