4.5.1.￿Front￿driveshaft
The￿front￿propeller￿shaft￿has￿been￿carried￿over￿from￿the￿G01/G02.
4.5.2.￿Rear￿driveshaft
This￿is￿a￿steel￿prop￿shaft￿carried￿over￿from￿the￿F90￿and￿adapted￿to￿the￿F97/F98.￿The￿dimensioning￿and
strength￿of￿the￿prop￿shaft,￿the￿center￿bearing,￿the￿flange￿connecting￿to￿the￿flexible￿disc￿on￿the￿transfer
box￿and￿the￿flange￿connecting￿to￿the￿rear￿differential￿have￿been￿adapted￿to￿the￿higher￿torque￿of￿the
F97/F98.
The￿maximum￿permissible￿deflection￿angle￿of￿the￿propeller￿shaft￿must￿not￿be￿exceeded￿when￿working
on￿the￿propeller￿shaft￿center￿bearing.￿The￿instructions￿in￿the￿current￿repair￿instructions￿in￿ISTA
