Renault Clio: Sequential gearbox: Precautions for the repair

D4F or K9K, and JA3 or JA5

I - SEQUENTIAL GEARBOX

WARNING

If any operation is carried out on the electro-hydraulic unit, it is essential to clean the unit using a cleaning product and compressed air.

Never leave the circuit open and never use a high pressure cleaner.

II - SEQUENTIAL GEARBOX COMPUTER

To disconnect the computer, switch off the ignition and wait for 1 minute.

III - ELECTRO-HYDRAULIC UNIT

Discharge the pressure accumulator using the Diagnostic tool before any operation on the electro-hydraulic unit.

Pressure accumulator: Removal - Refitting

K9K, and JA5

REMOVAL

I - REMOVAL PREPARATION OPERATION

IMPORTANT

Before any operation on the sequential system, discharge the accumulator using the Diagnostic tool.

• To discharge the accumulator, run command " Discharge pressure accumulator " AC081.

  To confirm the pressure drop, read the " Hydraulic pressure " parameter for the resulting value.

  If there is still pressure in the accumulator, re-run the " Discharge pressure accumulator " command until the pressure is negligible and will not pose a risk when the high pressure pipes are removed.

  The pressure reading must be close to zero.

• Remove:
  • the battery (see Battery: Removal - Refitting) (MR 392, 80A, Battery),
  • the battery tray (see Battery tray: Removal - Refitting) (MR 392, 80A, Battery),
  • the air filter unit (see Air filter unit: Removal - Refitting) (MR 392, 12A, Fuel mixture).

• Remove:
  • the lifting eye nut on the gearbox (1),
  • the lifting eye on the gearbox (2).

II - OPERATION FOR REMOVAL OF PART CONCERNED

• Remove the pressure accumulator (3) using the (Mot. 445).

REFITTING

I - REFITTING OPERATION FOR PART CONCERNED

• Fit the pressure accumulator.
• Tighten the pressure accumulator using the (Mot.445).
• Affix the safety label to the pressure accumulator.
• Refit:
  • the lifting eye on the gearbox,
  • the lifting eye nut on the gearbox.
• Tighten to torque the lifting eye nut on the gearbox (21 Nm).
• Refit:
  • the air filter unit (see Air filter unit: Removal - Refitting) (MR 392, 12A, Fuel mixture).
  • the battery tray (see Battery tray: Removal - Refitting) (MR 392, 80A, Battery),
  • the battery (see Battery: Removal - Refitting) (MR 392, 80A, Battery),

II - FINAL OPERATION.

• Carry out the necessary programming (see Fault finding - Replacement of components) (MR 394, 21B, Sequential gearbox).

WARNING

After the accumulator has been fully filled (15 seconds after the ignition has been switched on): the oil is at the MIN mark.
