Fellas,

I`m fitting my 2nd cyclone 5.

Did you use the little shim that fits between layshaft and bearing in the endplate?

also, damn the splines on the gear cluster have a realiy tight tolerance! I have to use a 3 pronged puller to get my LTH cluch off.

Job done.

Piece of cake with the granturismo endplate and octipus layshaft.
Ended up with 1mm gear shim, no shim under the layshaft and no shim over the gear cluster.

Fingers crossed. haha

Not expert by any means, but I would think that if a groove is machined, the gear would be very thin where you machine the groove, making it weak..
That's not going anywhere...
