ATTENTION: ALL DMC DEALERS/SERVICE MANAGERS
SUBJECT: ADJUSTABLE CLUTCH LINK - MANUAL TRANSMISSION
Reports have been received that difficulty in achieving
full clutch disengagement is being experienced on some
vehicles. This difficulty is generally experienced when
engaging first and reverse gears after the vehicle has
reached operating temperature.
If this condition exists, proceed as follows:
Bleed the clutch hydraulic system to ensure there is no
air trapped in this system using the following technique:
A) Check the clutch fluid level and fill if required.
NOTE: Brake fluid with a DOT 4 or higher
rating MUST BE USED.
B) Attach a bleed tube to the bleed screw (8 mm) on
the clutch slave cylinder and place the other end
of this tube in a container holding clean brake
fluid of the same rating.
NOTE: Make sure the bleed tube stays sub-
merged in the fluid.
C) Open the bleed screw and slowly but fully depress
the clutch pedal to the floor, close the bleed
screw and slowly release the clutch pedal. Repeat
this step a minimum of six (6) times and until all
possible air is purged from the system.
NOTE: When performing the above step, make
sure the reservoir level does not be-
come so low as to draw air into the
system at the master cylinder. Top
up as necessary.
continued ...
D) Fill the clutch fluid reservoir (DOT 4 or higher)
as required.
SPECIAL NOTE:
Pressure bleeding (Similar to brake bleeding)
may be performed. However, because the clutch
reservoir to master cylinder feed hose is se-
cured with pinch-type clamps, only very low
pressure should be used to avoid the feed hose
from disconnecting.
If clutch disengagement difficulty is still experienced
after bleeding, an adjustable clutch link assembly may
be installed to overcome this problem. This adjustable
link has been introduced as a service fix only if bleed-
ing does not correct the condition. This adjustable
link will provide extra clutch pedal travel thus provid-
ing addition clutch movement.

Adjustable Clutch Link Installation
The clutch pedal stop bolt and weld nuts must be removed
to permit the pedal to be raised. To carry out this
operation, the following procedure should be observed
(Figure 1).
A) Remove and retain the two (2) spring clips (SP10115)
securing fixed clutch rod. Remove the fixed clutch
rod.
B) Remove both clevis pins. It may be necessary to
carefully lower the steering column to gain access.
NOTE: Care must be exercised not to damage
the steering column.
C) Unscrew the 10 mm clutch pedal stop bolt from the
top of the pedal box and discard.
D) Using a hammer and sharp chisel carefully shear off
the 10 mm clutch stop nuts welded on both sides of
the pedal box (Figure 1).
E) Assemble the adjustable clutch link (Figure 2) (Part
Number 133188). Adjust both clevis ends evenly on
the threaded rod so as when the link is secured the
clutch pedal is 20 mm (3/4") higher than the brake
pedal (Figure 3).
F) With the link adjusted and positioned install the clevis
pins.
G) Reinstall spring clips to retain clevis pins, and
tighten lock nuts.
