Screw in

two M12x100 hex screws

(AF size 19).

Space limitations mean that no screws longer than M12x100 can be used.

Therefore, spacer blocks (approx.

20 mm) must be placed under the screws.

When the bearing has been pressed free of the bearing bolt, remove the screws.

Use a piece of square timber (1) to force the chassis apart at the front and rear.

Support the chassis at the rear using another piece of square timber (2).
