Transmission assembly
2.9.1 Gearbox housing pre-assembly
Before putting together the transmission, all components of the transmission must be
cleaned and degreased thoroughly. In addition, a visual inspection must be carried out.
Especially the visual check of the oil holes is necessary to ensure perfect function of
the transmission. Because some work processes in these instructions are linked with
each other, completing individual work processes is possible only keeping the
complete assembly instructions in mind.
Mounting studs
Before mounting the studs, the thread holes must first be cleaned thoroughly with
petroleum benzine (brake cleaner) and afterwards with acetone. The gearbox housing
and the gear housing must finally be blown out with oil-free compressed air. A special
installation tool must be used to screw in the studs. The studs are not tightened with
a turning torque. After the studs are inserted, the adhesive connections have to set in
an oven at 130°C (266 F) for approx. 40 minutes. The heat of the housing can be used
for the next work step (inserting the bearings).
