1995 RENAULT MEGANE SCENIC ESP

MANUAL GEARBOX
Speedometer drive gear
REPLACEMENT
1st case :
Only the speedo gear or the pin is damaged.
REMOVAL
The gearbox does not have to be completely dis-
mantled.
Release the left hand driveshaft.
Remove the sunwheel spider.
Rotate the differential by hand so that the speedo
gear is accessible.
Unclip the pin by pulling it vertically using a pair
of long nose pliers.
Using these pliers, remove the gear from its hou-
sing.
REFITTING
Refit a new speedo gear using a pair of flat nose
pliers.
The gear and its pin should be refitted by hand.
The pin must be correctly positioned with respect
to the key lugs on the gear due to the elasticity of
the lips of the pin.
21
Ensure that it is correctly clipped in.
Refit the sunwheel spider.
2nd case :
The speedo gear and crown wheel are damaged
The gearbox has to be removed and the final drive
has to be dismantled.

ENGINE
Separate the gearbox from the engine by :
- removing the starter motor,
- removing the bolts from the automatic trans-
mission sump.
Remove:
- the hoses on the exchanger, Lift the engine from the sub-frame.

- the converter bolts
- the bolts around the gearbox and the TDC sen-
sor.
Separate the automatic transmission from the en-
gine.
REFITTING (special notes)
Refit the converter by positioning it with respect
to the mounting bolts.
Tighten the bolts around the automatic transmis-
sion.
Refitting is the reverse of removal.
Aligning the engine sub-frame with the body will
be made easier by positioning two approximately
100 mmlong threaded rods in the two front sub-
frame-body mountings.
Tighten the sub-frame front mounting bolts to a
torque of 6 daN.m. and to a torque of 11 daN.m at
the rear.
Tighten all nuts and bolts to the re-
commended torque.
Fit the caliper mounting bolts using Loctite
FRENBLOC and tighten them to the correct tor-
que.
Press the brake pedal several times to bring the
pistons back into contact with the brake pads.
Fill:
- the cooling circuit and purge it (see chapter 19),
- the engine with oil if necessary.
NOTE : check that the steering shaft yoke spacer is
in place when refitting.

REFITTING
Refit the nut, turning the same number of turns as
when it was removed.
Align the marks made on the nut and the sump.
Replace the bolt (D) and the locking plate (E).
Refit the shield after having replaced the lip seal if
necessary (see paragraph 1).
Fill the final drive with oil.
95791-2R
REMOVAL
Drain the final drive and remove the shield, as ex-
plained in paragraph 1.
Locate the position of the nut (F) with respect to
the sump by putting a mark on one of the teeth
and on the face of the sump.
Remove bolt (D) and the locking plate (E) from the
nut using tool B.Vi. 1323, remove the nut, coun-
ting the number of turns it takes.Replace the O-ring on the nut, cleaning the seat
properly and lubricating the new seal with final
drive oil.

Insert the driveshaft stub axle into the hub.
It should enter freely until the thread shows allo-
wing the stub axle nut to be fitted.
If any problems arise, use tool T. Av. 602. Right hand side
With the protector in place, coat the splines of the
seal on the gearbox side with
MOLYKOTE BR2
grease.
Position the driveshaft with respect to the sun-
wheel and engage it.
Check its position with the angled pin of tool
B.Vi.
31-01.
Fit two new roll pins : tool B.Vi. 31-01. Seal the pin
holes with
RHODOSEAL 5661 (eg. : CAF 4/60
THIXO).
NOTE :
chamfers on the leading edges of the sun-
wheels make it easier to fit new roll pins.

REFITTING
Lubricate the driveshaft and slide on:
- a new retaining clip,
- the rubber gaiter (4) with the metal insert (7)
and the metal retaining cover (3). Remove the yoke.RC 490 seal

NOTE : as the yoke does not have a stop tab, it
can be removed without using force.
Do not remove the rollers from their respective
journals since the rollers and the needles match
each other and should never be interchanged.
Remove the circlips (depending on the model).

Never using thinners for cleaning these compo-
nents.
With a press, extract the triaxe component by
using a
FACOM U53G type extractor tool.
