AAN engine to ABY gearbox

[spink]

At some point the flywheel must have been changed because I just fitted the aan engine with the clutch that came with it and it needs the spacer

I would have noticed it having a spacer when i removed the engine Rik.are you sure you didnt put the aby clutch on it?(sorry if thats been mentioned already,cant be arsed reading it all on my phone)

could be simply the wrong release bearing!

measure from the back of the block to the point of the clutch fingers and i will measure my AAN one tomorrow for you

will try to measure inside the input shaft size too

Defo used same clutch

[Rikki Kitto]

Bought new release bearing, is there different ones for aby aan?

[Rikki Kitto]

remove the clutch from the engine and try it up to the gearbox without it on

Why

[jade]

Clutch mounting face to block casting, top part is 48.5 mm on a AAN engine, maybe some help ?

[Sleeper_Avant]

Drove to my work place and i took a few snaps today for you, hopefully be of some help

will pist when i upload em in a few minutes

here we go then, bit dificult due to lack of light and space to get in but did the best i can lol

height from back of ring gear/flywheel to tip of pressure plate fingers is approx 87mm .......... give or take

Hope this helps

interesting to know the AAN C4 cars have been fitted with spacer and without spacer. Does this mean that the AAN dualmass flywheel / clutch setup thickness has increased / decreased over time?
I still do not understand why this should be different compared to the ABY and ADU engine setups (similar bottom-end, 01E gearbox, and always a spacer in between).

The only difference there could be is in the UrS4/S6 gearbox version of the 01E maybe. Did the automatic, 5-speed and 6-speed versions of the 01E gearbox have different external features?

Suppose the easiest thing to do is use a spacer anyway

[Sleeper_Avant]

this might cause problems with disengaging the clutch, i.e not enough travel mate

maby the thrust bearing is different, when i put my AAN in the A4 i hat to pull it in with a ratchet spanner, so took it apart and used the URS4 bearing (that was shagged) and it made a difference

just a thaught
