REPXPERT shares step-by-step guide for six hour repair.
LuK reveals essential tips and advice on clutch, flywheel and CSC replacement for the 2.0tdi 4motion.
Talking through a recent replacement using a two post ramp, two transmission jacks and an engine bridge tool, LuK explain that the only special tool requirement needed is a universal alignment tool for the clutch driven plate.
The repair starts under the bonnet.
First, disconnect the battery terminals and stow safely.
Remove the intake pipe and the air filter housing.
Remove the battery and battery tray to expose the top of the gear box.
Remove the white plastic locking clip (fig1) that holds in place the reverse gear lever and cable and detach from position.
Remove the locking nut from the gear selector cable and remove this from its keyway stub (fig2).
Unbolt the selector cable mount and stow safely away from the working area.
Remove the retaining clip holding the hydraulic line into the clutch master cylinder (fig3) and disconnect the line and blank off.
In our case we held the line vertically and blanked off using a plastic cap.
You could also clamp the line with a hose clamp and then disconnect the pipe.
Stow the hydraulic line safely.
Do not operate the clutch pedal.
Remove the top two bell housing bolts and remove the upper starter motor bolt.
Disconnect the electrical connector from the starter motor by pulling the red tab back slightly (fig4) to unlock the connector allowing it to ease off from its position.
Stow the cable safely.
Unclip the plastic cover over the main power cable to the starter and unbolt the cable and stow.
Disconnect the reverse light switch and remove the earth cable from the gearbox.
Remove the two bolts that hold a plastic support bracket for the wiring loom and the starter motor in place and remove the both parts.
Install the engine bridge and remove the top gearbox mount.
Raise the vehicle and remove the under tray, remove both front wheels and partly remove the left wheel arch liner.
Drain the gearbox oil.
Disconnect the oil level/temperature sensor plug and stow. Remove the engine/gearbox stabilizer arm bracket and then remove the stabilizer arm (fig5).
Remove both driveshaft bolts and remove the bolts on both sides from the wishbones and disconnect them from the stub axles.
In our case we decided not to remove the prop shaft, exhaust and transfer box, but to remove both drive shafts and sub frame as this gives plenty of room to disconnect the gearbox from the engine.
The O/S drive shaft should be unbolted from the flange on the transfer box.
Unbolt the steering rack and anti roll bar and disconnect the wiring harness from the sub frame. Remove the six bolts securing the sub frame in place and using a transmission jack for support carefully lower the sub frame.
Remember to remove the 6mm allen key bolt through the transfer box (fig6) as you will not separate the gearbox from the engine.
Support the gearbox with a transmission jack and then remove the remaining bell housing bolts.
Carefully separate the gearbox from the engine. It will have to be slightly lowered on the transmission jack and pulled into the wheel arch a little but you should have just enough clearance to lower the gearbox to the floor.
With the clutch removed, check the Dual Mass Flywheel (DMF) for signs of heat stress and evidence of grease loss.
The DMF should also be tested for freeplay and rock between the primary and secondary masses, LuK tool number 400 0080 10 is specifically designed for this purpose on all LuK manufactured DMF’s.
Full instructions and tolerance data for all LuK DMFs are contained on a CD which comes with this special tool.
Clean the first motion shaft splines and any debris from the bell housing.
It’s important to ensure that the release bearing is always replaced if the clutch and/or DMF are worn out.
Put a small dab of high melting point grease (not a copper based product) on the first motion shaft splines and make sure the new driven plate slides freely back and forth.
This not only spreads the grease evenly but also makes sure you have the correct kit.
Wipe any excess grease off the shaft and driven plate hub. Using a universal alignment tool and checking the driven plate is the correct way round the clutch can be bolted to the flywheel evenly and sequentially.
Before fitting the gearbox make sure the locating dowels are in place and not damaged.
Refit any that have become dislodged and refit the gearbox.
Make sure the gearbox bell housing bolts are secured before lowering the jack. Refitting is the reverse of the removal.
