3.5 DRIVE MOTOR ASSEMBLY - SERVICING
NOTE: The following drive motor servicing instructions refer
to machines built to both the original design -
(Machines built prior to Serial Number -
0130005271)
and a new design - (Machines built
since Serial Number - 0130005271). The major differ-
ence between the two designs is the drive motor
mounting frame, the original is two separate mount-
ing frames the new design is a one piece frame
mount.
Components on the drive motor assemblies may be ser-
viced without removing the motor mounting frame assem-
bly(s) from the machine, if necessary.
The component parts of the left and right drive motor assem-
blies are identical except for the drive motor mounting frame
assembly.
