Turn
the flonge
on the centering
orbor so thot
the longer, cylindricol port
foces the clutch,
push it ogoinst the friction plote
hub, ond olign
the ends of the levers to touch the flonge.
A deviotion from the ploneness
of 0.1 mm
is
permissible. Use feeler gouges for checking
this deviotion.
lf it is not possible
to odiust the out-trovel of
the clutch releose levers to o volue given
by the
length of the flonge cylindricol port
due to
excessive weor
of the friction plote, odiust to
the next higher volue.
Clinch nuts on the
odiusting nuts bocked off up to the end of the
threod ore o worning of o weor limit which pre-
cludes ony further odiustment
of the clutch.
4. After hoving reossembled
the engine with
o new or odiusted clutch,
check ond, if necess-
ory, odiust the cleoronce between the releose
levers ond the throw-out beoring -
see Chop-
ter 15.4.
3.3 CLUTCH DISMANTLING
Owing to its simplicity,
it is not necessory
to
describe in detoil the dismontling
of the clutch,
but some speciol feotures
deserve ottention.
1. lf the friction plote
ond clutch cover ore
intended to be re-used, mork their relotive
positions using centre punch
morks to preserve
the originol bolonce of the ossembly.
2. To dismontle
the clutch, it is
necessory to
compress the clutch cover to relieve the stress
of the releose lever bolts. For this purpose
use
the MP 2-101
ossembly plote
shown in Fig.3.4/1.
After screwing off the releose lever nuts ond
compressing the clutch cover,
the clutch is
reody for dismontling.
3.4 CLUTCH REASSEMBLY
1. Locote
the clutch pressure
plote
on the
MP 2-101
ossembly plote
ond fit springs
on the
cylindricol bosses. Before fitting
the springs, it
is odvisoble to check them for
complionce with
the volues specified
in the following Toble.

Instoll retoining plotes
on the clutch
springs ond fit the clutch cover with releose
lever springs in position.
Assemble the clutch
cover with the pressure plote,
observing the
morks indicoting their relotive positions.
When
ossembling new pot'ts,
their positions
ore of no
consequence.
3. Slip o 4.5 mm high pod
over the ossembly
plote bolts (the
plote
con be used
for Skodo
1000 MB ond Skodo 100 cors os well,
ond by
using pods
of different heights, the plote
con be
odopted for different
types of clutches), fit the
yoke of the
iig on
the plote
bolt ond compress
it by screwing down the nut till the bottom port
rests on the pod.
When compressing the clutch
cover toke core thot the projections
of the
pressure plote
ore correctly centered in
the
cover slots to prevent
o distortion of the clutch
cover.
4. Slip the bottom ends of the releose levers
under the springs instolled in the cover ond fit
them with their longitudinol
slots on the sup-
ports. Slip odiusting woshers on the bolts of the
pressure plote ond screw down the nuts with
their cylindricol port
focing the woshers. Then
odjust the height of the releose levers with
these nuts so thot their ends touch the shoulder
of the yoke
bottom port.
The difference of the
lever height should not exceed 0.'l mm. This
odiustment olso sets the recommended
distonce
of the levers from the pressure
plote
beoring
surfoce.
Use clinch nuts for locking the odiusting nuts
in position,
put
supporting clips under the re-
leose f ever ends os shown in Fig.3.111 ond3.212,
ond slocken the nuts of the ossembly plote.
The
clips ore useful when fitting the clutch to the
f lywheel since it is not necessory to overcome
the tension of the clutch springs.
To Check Adiustment ond Bolance

Proceed
in the some woy with the
3rd- ond
4th-speed geors.
lf the morked position
of the neutrol is not
midwoy between the side morks (check
visu-
olly), remove the pinion,
mork the positions
of
the striking forks on
their rods (preferobly
on
either side), slocken the forks ond 'rnove
them
toword the required centre by
the distonce of
the deviotion of the neutrol morking. Then lock
the striking forks in position
with screws.
For the striking fork tightening torgue see
Chopter 1.8. 13. Adiust the reverse geor position
so thot
there is o gop
of obout 2
mm between its teeth
ond the odioining teeth, ond swing the striking
fork of the first ond second speed
to moke sure
thot it connot foul
the teeth.
14. Reinstoll the pinion
with its respective
woshers ond lock it in position.
Shift the strik-
ing fork rods to moke sure thot, for exomple,
o movement opposite to the required one of the
striking forks did not toke ploce,
i. e. thot the
neutrol is midwoy betvr'een the engogement
positions of the synchronizing clutches. Correct
ony error ond remove
ogoin the pinion.
Fitting Drive Geors ond Clutch Shqft
15. lnstoll the ossembled drive shoft into the
housing ond slip the splined bush on it.
Top home the seol ring with its seoling lip
pointing outwords into the guide
of the clutch
thrrowout sleeve, ond smeor it with oil. Then
threod the clutch shoft through the ring to
instoll it into the splined bush ond put
it into
the housing together with the guide provided
with o cooting of seoling compound on its cyl-
indricol bedding surfoce. Secure both the shoft
ond the sleeve with circlips.
lnstoll the sleeve guide
with its droin hole
level with the porting plone
of the housing ond
focing the pinion.
For the speciol seoling compound see the
note in Chopter 10.1.
16. Put the pinion

the bore of the differentiol beoning ond the
fitted cover, fit the ossembled differentiol in it,
ond close the housing with the other housing
holf ofter hoving cooted the seoling surfoces
with o seoling compound.
Fit o rubber ring in the recess of the boss
beside the stud
bolt ond put
o spring wosher
under the nut. Tighten the remoining nuts
without ony woshers (the
stress of the bolts
ofter the tightening of the nuts provides
for'
their suff icient securing). Tighten the nuts
moderotely for the time being.
For the speciol seoling
compound refer to the
note in Chooter 10.'1. 17.
Proceeding through
the bore of the differ-
entiol beoring in the upper holf of the housing,
fit another
iig, the MP
5-104,
on to the differen-
tiol with flonges clomped so os to fit
into the
topered roller beoring cover, locote the cover

the cover by meons
of three
nuts. lf the clomping or drowing close of the
flonges of this jig
proves inodequote, it is
necessory to drow close the flonges olso of
the
first, previously
inserted
iig.
18. Drive the guide
of the clutch throwout
sleeve into the housing using the MP 3-103 drift,
top home the drive shoft, ond insert
two od-
iusting woshers under the collor of the
pinion
shoft boll beoring on both holves of the housing
ofter hoving determined their thickness by
meosuring. Using o wire needle

thot they do not overlop the porting plone
of
the housing,
then instoll the cover ond spring
woshers, ond tighten the nuts (seeChopter
1.8).
19. Fosten the housing by tightening the nuts
(see Chopter 1.8) ond lock in position
the guide
of the clutch throwout sleeve with the respect-
