b) Setting the Tooth Flank Play for Engine / Main Drive gear Wheels

Regularly check the tooth flank play between en-
gine motor drive pinion and main drive pinion (1).
• For this, push a paper strip (80g/sheet) between
the gear wheels.
• For correcting the tooth flank play, loosen the
four motor fastening screws on the left and right
(2) and adjust them as required.
The tooth flank play is set correctly when the pa-
per strip can be easily inserted and when turning
results in a clearly serrated strip coming out at the
other end.
