Overview over the mounted first stage unit
ready to mount in the frame. Please note
that the bearing blocks are assymetric ,
the rounded contour is longer than the rec-
tangular contour and is placed on the left
side (view in flight direction).
Add the toothed belt 713 in the belt wheel
and position the unit as shown on the cor-
responding holes of the frame.
Mount the first stage with four screws
M3x6 D196 using Loctite. First mount all
screws loose. If all screws are mounted
then tighten them. After that check the
gear mesh. There must a small play be
noticable. Is the mesh too small then open
all screws of mainshaft and first stage
again, pull the mainshaft unit backwards
during tightening and the first stage for-
ward and check the gear mesh again.
