Before maintaining the entire automated mechanical

transmission, use a special repair tool to remove the

energy storage.

When doing this, comply with the control procedure

described

in

the

section

of

“ENERGY

STORAGE”.

Once accomplishing this procedure, the buzzer will

make a buzzing sound.

In order to confirm that the pressure therein has

dropped into the specified range, refer to the section

of “PR018 HYDRAULIC SYSTEM” to know the

standard resultant pressure range.

If you fail to do this, repeat the control procedure

described in the section of “ENERGY STORAGE”

until the pressure becomes very low and it has no

risk to remove the high-pressure pipeline.

Removal:

Before removing the hydraulic unit, you shall

remove its seat stand and the gearbox.

With regard to how to remove the seat stand, refer

to Chapter 21 of Service Manual 305.

When removing the gearbox, you shall be careful

not to damage the hydraulic unit.

Remove the electronically controlled hydraulic

unit of the transmission.

Remove the clutch fork cable.

Remove the connector of the original speed sensor.

In order to loosen the speed transmission control

shaft, rotate the shaft a quarter turns by using a

screwdriver.

Lock the control shaft.

The clearance on the shaft should be aligned with

the mark.

Loosen the control shaft.

The clearance on the shaft and the mark are at the

right angle.

Handle used to fix the electronically controlled

hydraulic unit.

Put two half-moon parts and circlip into the control

shaft groove.

Smear MOLYKOTE 33 (moderate) onto the two

half-moon parts.

Unscrew the six fixing bolts and remove the

hydraulic unit.

Replace the two half-moon parts:

Check whether their positions are correct.

Place the control shaft onto the drive mechanism

module and lock it.

Screwdriver impression and shaft pin should be

aligned respectively with the marks.

Mount the flat washer.

Remount the hydraulic unit onto the transmission.

– ELECTRONICALLY CONTROLLED HYDRAULIC UNIT

Remove the handle of this hydraulic unit.

Fix the hydraulic unit to the transmission by

tightening the fixing bolts.

Place back the control shaft cover (lubrication

washer).

It is easy to remount the hydraulic unit onto the

transmission and you need only to carry out the

procedure opposite to the removal procedure.

Remove the outside washer for oil tank cap.

Fill the ELF RENAULT MATIC D3 SYN

DEXRON oil to the degree that the oil level is 32 to

38 mm higher than the lowest mark line.

Perform the corresponding test by using a special

tool.

(Refer

to

the

section

“SPECIAL

REQUIREMENTS ON CHANGE OF SYSTEM

PARTS AND COMPONENTS”)

Oil filling into oil tank

The mark shown on the oil tank is the lowest

standard.

Carry out the energy storage removal procedure.

Make sure that the oil level is 32 to 38 mm higher

than the lowest mark line.

Important tip:

The oil level will be at the position indicated by the

mark line (MIN) when the energy storage has been

fully inflated (15 seconds after ignition).

MECHANICAL TRANSMISSION – ENERGY STORAGE

Tightening torque (unit: DAN.M):

Energy storage

Lifting ring fixing

2.1

Operation:

Energy storage is used to ensure that the pump runs

intermittently. Its full inflation can guarantee three

speed loads of clutch engagement/disengagement.

Rated operation pressure:

200C: 45 to 50 bar

-300C: 35 to 44 bar

Remarks:

Before maintaining the entire automated mechanical

transmission, use a special repair tool to remove the

energy storage.

When doing this, comply with the control procedure

described in the section of “ENERGY STORAGE”

(AC081).

In order to confirm that the pressure therein has

dropped into the specified range, refer to the section

of “PR018 HYDRAULIC SYSTEM” to know the

standard resultant pressure range.

If you fail to do this, repeat the control procedure

described in the section of “ENERGY STORAGE”

until the pressure becomes very low and it has no

risk to remove the high-pressure pipeline.

The pressure reading should be nearly zero.

Removal:

Remove the battery.

Use the injector to evacuate the oil tank.

Remove:

-

Fasteners on the transmission housing

-

Energy storage

Remounting:

Stick the warning label onto the energy storage.

Carry out the remounting procedure that is opposite

to the removal procedure.

Fill the ELF RENAULT MATIC D3 SYN

DEXRON oil to the degree that the oil level is 32 to

38 mm higher than the lowest mark line.

Perform the corresponding test by using a special

tool. (Refer to the page 21-36 of section "special

requirements on change of system parts and

components of KIT electrically controlled hydraulic

system")

Oil filling into oil tank
