LUK/Sachs flywheel identification

[davemotor]

For anyone with a Mk2 Leon, Mk3 Toledo or Altea TDI -
If you ever need a flywheel, you need to know which make is fitted to your car.
There is an inspection aperture in the bellhousing and if you rotate the crank you will see one of the setups below.

The top one is LUK with parallel grooves
The bottom one is SACHS with curved grooves.
Thanks to Flapper for making the pic work

Hi David, the pic seems to have disappeared. Do you still have it as it would be really handy to see the difference between the two flywheels.

Cheers!

funny you posted today as i had an LUK Flyer in hand earlier showing the difference on both sides so i would guess maybe possible to id through the starter hole maybe ?

i'll get the technote and link to it later

That would be a big help, cheers buddy!

 

[Fl@pper]

can't find the direct link to the ID report sadly but ill reprint it tomorrow and search for it so you can get the pics and explanations

meanwhile there's a good DMF explanation + diagnosis guide etc that will help some i guess

Excellent, cheers for that mate.

This is the one
If you look thru the inspection aperture in the bellhousing, you can see the markings - either straight or horseshoe shaped
Saying that, if you are replacing flywheel and clutch together then the make doesnt matter - as long as flywheel and clutch match

Great stuff, thanks very much!

 

[Fl@pper]

here ya go - but as David said above if you are replacing both clutch and flywheel then as long as you have matching parts it doesn't matter what is fitted

 

[Fl@pper]

here ya go - not so sure the starter hole is enough to see but as David said above if you are replacing both clutch and flywheel then as long as you have matching parts it doesn't matter what is fitted

This would make a good sticky for the Leon section

Does anyone know where the inspection aperture on the bellhousing is located i.e from top of engine bay or from underneath?

 

[Fl@pper]

This would make a good sticky for the Leon section

ya right so it's been moved + stuck
