When sliding the GMU onto the drive shaft it
may be advisable to use suitable lifting
equipment. To make the process of aligning
the GMU easier it may be advisable to
remove the motor fan cowel and turn the fan
until the key and keyway align with the end
of the shaft.
Once completed, refit fan
cowel before powering the GMU!
Figure 2n
To complete the coupling of the GMU to the
pump head use the provided bush and
shoulder bolt to ensure that the torque arm
is correctly aligned and to reduce
exaggerated movement of the GMU.
NOTE: The torque arm allows the GMU a
certain amount of movement during
operation, this feature reduces load on the
drive shaft.
Figure 2o
To complete installation of the GMU use the
crescent clip supplied to stop the GMU from
sliding off the end of the shaft.
