View Full Version : 020 Gearbox Clutch Mechanism

1 - pressure plate
2 - friction plate
3 - kit assy (as genuine)
4 - plate washer for pressure pate to flywheel
5 - crankshaft bolts
6 - thrust plate
7 - thrust plate spring
8 - pressure plate > flywheel bolts
9 - inspection cap (green VWlogo) levers off
10 - thrust bearing
11 - radial shaft / cable arm
12 - splined release arm (common to break or strip splines)
13 - securing clip for release arm
14 - return spring for release arm
15 - stop buffer
16 - seal for radial shaft
17 - push rod (common for pushing through thrust plate #6)
19 - balance weight
in short with pedal pressed down (ish)
cable pulls #11 upwards
#11 twists #12 inwards
presses against #10
pushing #17 inwards
against #6
releasing pressure off #1
releasing #2 for clutch engaged
common faults
#12 bends/breaks/strips splines easily checked by lifting off #9 and inspecting it under operation
#6 breaks open letting #17 burst through it
either way press pedal down - no clutch or to start seems harder to get in gear - similar to pedal box symptoms too :(:(
020 Clutch...
Sachs clutch kit from Euro Car Parts actually contains
1 - pressure plate
2 - friction plate
5 - crankshaft bolts
6 - thrust plate
7 - thrust plate spring
8 : pressure plate > flywheel bolts
N 10013401 : 12-point head bolt :M7X40X20 /
What sized socket fits those? :confused:

Me too usually...... I came to the end of the line though... :D
9mm 12 point socket fits 020 flywheel bolts.
Just to illustrate the 020 thrust plate problem a little further -
The thrust plate lives in the middle of the flywheel clutch assembly and operates the clutch release plate. The thrust plate is operated by a pushrod that runs through the middle of the 020 box.
The following pics illustrate a rod that has worn through the middle of the release plate.

(a new thrust plate is shown on the left in the above picture)
You can tell this has happened if
1) clutch pedal has dropped to the floor
2) if you remove the round endplate from the gearbox, you can see that the pushrod /release bearing has moved well away from the operating lever - as below.

Try to withdraw the pushrod with a magnet (having first taken the release bearing out) before removing the gearbox - otherwise, you may find the pushrod is skewering the gearbox to the flywheel/clutch assembly, making gearbox removal extremely difficult.

Round end to the pressure plate, I'd say.

Do you know why the push rod wears through the pressure plate ??

It's just down to the extremely simple design. I reckon it's intended that the clutch friction surfaces should wear out before the release plate, then they all get changed. However the release plate hasn't always been changed - or because of careful driving, the friction surfaces have lasted longer than the release plate.
*Release plate is better terminology as the pressure plate is attached to the crankshaft.

Sorry to be a pain dave. But do you or any of your fellow seat guys know for 100% which way roundthe rod goes only ive got a new one just turned up. One end is rounder than the other as i guess you would know.????? Soz for pecking.
always fitted em rounded to the plate as it's domed and the flatter end to the bearing as it's flatter
always fitted em rounded to the plate as it's domed and the Fl@tterer end to the bearing as it's Fl@tterer
