Replacing the Outer Link Motors or Harmonic Drives in the
PFDD6
DANGER:
Before replacing any parts, the AC power should be
disconnected. Removing the front cover allows access to the AC power
terminals.
Tools Required:
1.
3.0mm hex driver
2.
2.5mm hex driver
3.
2.0mm hex driver
The motors and harmonic drives in PFDD6 are not items that can be replaced in the field. There are two
major subassemblies in the DD6 outer link. These are the J5/J6 assembly and the J4 assembly. These
are factory replacement items. In order to replace one of these assemblies in the PFDD6, the user must:
1.
Remove the foam covers from the outer link, including J4 and J5.
2.
Remove the J5 cover plate from the J5/J6 axes.
3.
Unplug the J4 to J5 harness from the J4 slave amplifier, pull harness through J4 into
J5 housing.
4.
Remove the J5/J6 axes from J4 by removing 8 M4 X 8 SHCS.
5.
At this point the J5/J6 assembly may be returned to the factory and a new assembly
attached.
