Face Plates – Removal and Installation
Inboard
1. T
o remove the face plate first loosen the
two set screws ‘A’ of Figure 19. Insert the
indexing pin ‘B’ into one of the three
holes and screw it in until it fully engages
one of the indexing holes in the spindle.
You may have to turn the face plate by
hand until you can feel the pin engage
the hole. The spindle should now be
locked. The face plate can now be
unscrewed counterclockwise off the
spindle. If more leverage is needed
insert the knock out rod into hole ‘C’.
