Post by: tidla on 06 November 2010, 22:16:30
how come the idea didnt catch on, slide the spline out the way. take the clutch out thru a cutout in the bell housing??

Clutch on an Astra F was apparently a 30 min job including boiling the kettle, same with the last Cavalier before it became a Vectra.
Clutch on an Astra G involved lowering the front subframe - been there done that
Progress eh!!

My first car was a Mk. I Astra, that had the plate on the bellhousing to facilitate easy removal of the clutch assembly, I also had a Mk. II Ashtay ('H' reg.) that didn't have a plate.
Having also had a few Cavaliers from around the mid nineties I can also say they never had the plate...

i can't really understand why they did it in the first place - it can only have cost them money to do - extra components to produce.

designing cars to be easy to work on is never a good idea for a manufacturer

Mk2 Astra 1.8i done in thrity mins from stopping the car to driving out of the workshop

The reason they stopped it was because they had to make the flywhell heavier due to the EU Emission rules. The only way they could do this was to make the flywheel thicker, couldn't make it any bigger in dia' as the bellhousing wasn't big enough

I'm also pretty sure the flywheels on the quick change were stepped aswell so the friction plate was sunk into the flywheel.

on the very last one they were but the flywheel was so thick that it filled the drop out hole.

One things like Nova, Astra, Cavalier etc it was just a normal flat flywheel

Last of the cavs had a pot flywheel so you could not change them without box removal

Had to do the brother-in-laws clutch on his astra last month & that is when i found out about the pot flywheel >:(, managed to unbolt the g/box & move it enough to let the clutch drop out without removal of driveshafts. :y
