Controls, Housing
Adjusting gear shift linkage
(Downward pressure system)
Place lever in neutral.
Lever plate position
Align centering holes -arrows- in lever
plate and housing cover
plate.
Note:
The tapped holes for the bolts
should now be in the centre of
the slots -arrow-. If they are not,
turn the lever plate 180.
Secure the lever bearing.
Loosen the clip. The
selector lever must move
easily on the shift rod.
Pull the large boot off
the lever housing and
push it along the shift
rod. It may be necessary
to loosen the screws in
the housing cover plate
to free the boot.
-
Locate the shift finger -1- in the centre of
the stop plate -2-
The distances x must be the
same.
Set distance "a". With a 20 mm wide strip
of sheet metal.
Tighten clip in this
position.
Select all gears in turn
and check that they
engage easily and
without catching. Ensure
that reverse catch is
effective
Note:
If gearshift still sticks or is
spongy after correct adjustment,
adjust the retaining screw
Adjusting selector shaft
retaining screw
When gearbox has been
dismantled or if gearshift jams
or is spongy, the retaining screw
should be adjusted.
-
Adjust with gearbox out or
disconnect linkage from selector
shaft lever and place fox in
neutral
Note:
There are two different screws
Side pressure system
Shoulder =>arrow
Downward pressure system
A - Vehicles up to December
1974
(Side pressure system)
-
Turn slotted screw -1- in until it makes
contact.
Watch nut -2- while
turning screw (it starts to
move outwards when
contact is mode)
From this position, turn
slotted screw out 1/4 of a
turn and fit plastic cap
Renewing retaining screw
Install Part No. 020 301 241 A
and adjust as described at "B".
B - Vehicles from January to
August 1975
(Side Pressure system)
Turn locknut -2- back and retaining screw
-1- in.
Press selector shaft -4-
in until it contacts
reverse gear catch.
Turn retaining screw
out slowly until selector
shaft jumps out under
spring pressure and then
turn screw out 1/4 of a
turn further.
Lock screw in this
position.
-
C - Vehicles from September
1975
(On downward pressure system
only)
Loosen locknut -2- and turn retaining screw
-1- in until locking clip -
4- lifts off retaining
screw.
Turn retaining screw
back again until clip just
makes contact.
Tighten locknut.
Check: The clip should
lift as soon as shaft -3- is
turned slightly.

Modifications to the shift linkage
The parts listed below have been take over from the shift linkage of the 5 speed manual
gearbox. They will in future be the same for both gearboxes.
1. Boot with cap from April 1981
2. One-piece shift rod bearing from August 1980
3. Relay lever with larger rubber ball from February 1982
4. Type of grease
Boot with cap
Only the cap need be removed to make adjustments. The boot can be left in position.
One-piece shift rod bearing
-
The bushes riveted in the bearing plate now have larger grease pockets. The protective boots
have been discontinued.

2 - Shift rod
bearing
3 - Shift rod
4 - Clamp
5 - Selector rod
6 - Selector lever
Relay lever with larger rubber ball
The hole in the selector lever
has been altered to match the
larger rubber ball (30 mm
instead of 24 mm).
The selector lever for 4 and 5
speed gearboxes are thus the
same apart from the position of
the welded--in ball stud. As a
service part, a selector lever
with two welded-in ball studs is
supplied which can be used for 4
and 5 speed gearboxes.
1 - 4 speed
gearbox: Press selector
rod on at botton
2 - 5 speed
gearbox: Press selector
lever on at top
ype of grease
-
As with all other passenger car shift linkages, the linkage of this 4 speed gearbox is in future
to be lubricated with
Special lubricating paste white - Part No. AOS 126 000 05
-

Removing plug -arrow 2-.
Put in gear oil - SAE 80 or
80/90 to MIL-L 2105 (GL 4)
specifications - until oil flows
out of level checking hole.
Caution
Oil must be put in slowly to give
it time to level out uniformly in
the box. Stop for a brief period
(30 seconds) if necessary.
-
Modification
From Assembly date 07 05 4
Level checking hole discontinued. Oil is put in and
checked through the filler hole.
Service installation of the 5 speed manual gearbox
The 5 speed manual gearbox can be service installed in Golf and Scirocco vehicles from
August 1979 with 63 kw (85 bhp) amd 81 kw (110 bhp) engines.
The 5 speed gearbox can also be installed in vehicles built before August 1979 but this
changes the exhaust emission values slightly and may effect the vehicle Type Approval.
The following new parts have to be installed:
Designation Part No.
Gearbox 020 300 044 F
Knob 171 711 141 E
Cover plate 171 711 261 C
Relay lever 171 711 163 B
Selector rod 171 711 574 B
Selector rod 171 711 593 E
Selector lever 171 711 177 C
Mounting 171 399 113 H
Boot 171 711 195 C
Cover 171 711 210
Protective plate 171 711 229 A
and attaching parts for gearbox mountings.
Instructions on adjusting the shift mechanism are given in the booklet 5 speed manual
gearbox 020.
Note:
On vehicles up to December 1978 it may be necessary to make a small depression in the left
wheel housing in order to ensure sufficient clearance between gearbox and wheel housing. In
-
this case it is necesary to ensure that there sufficient clearance between wheel housing and
wheel in all supension positions and on all wheel locks.
The service installation in vehicles with 51 kw (70 bhp) and 55 kw (75 bhp) is not
contemplated due to the different engine characteristics.
-
Selector shaft cover modified
From gearbox date 22 01 0 the selector shaft cover -A- has
been provided with a rib -arrow
1- .
For this reason, the gearbox
housing has been provided with
a contact surface -arrow 2- in
the rib area.
Note:
The modified cover can only be
screwed into gearbox housings
with a contact surface.
The cover is not offered as a
service part beacuse the old
cover can be screwed into all
gearbox housings.
On some gearboxes there is an
O-ring fitted in addition under
the new cover.
On these gearboxes an O-ring
must once again be installed
when repairs are carried out.
Part No. N 903.543.01

Selector shaft lever serf-locking nut
In cases where customer complaints are received on difficult gear selection due to excessve
free play on the gearlever, it is possible that the selector shaft lever nut could be loose (see
illustration below).
Should this be loose, it must be replaced with a self-locking nut, part number N902 920 01,
avaiable from our P&A Department.
