Now press the top bearing 4448.31 into the bearing holder 4448.11, and slide this assembly up
against the shim washer below the freewheel sleeve. Now take the prepared layshaft assembly
and place it between the mechanics side frames 4450.9 and 4450.10, so that you can check
that the top bearing rests against the gear flange via the shim washer when the system is
assembled. If there is a gap, you must fit additional shim washers to compensate, but don't fit so
many shim washers that the bearings are under strain!
Once the spacing is set correctly, press the roll-pin into the gear flange completely and
permanently; check that the shaft rotates freely in the bearings, and tap lightly on the ends of
the shaft if necessary to help the bearings seat automatically.

dome bearing holder 4448.12. Grease the bearing.
