Hi,
I think your issue needs describing to CML directly rather than on here. Sounds like a genuine manufacturing fault and CML are extremely good at helping/advising their customers.

The bearings should be solid, no movement. The only movement in the layshaft should be slight in and out - which the shims are used to minimise as described in the manual, but not eliminate otherwise their is side load on the bearings (not good).
