17. Put the commutator cover on top of the commutator
ring with the flat surface towards the commutator (Fig.

holes in the drive plate.

18. Screw the eleven hex socket head cap screws
loosely into the metering package (Fig. 80).
NOTE: The commutator ring must be concentric with the
drive plate within 0.005 in. (0.127 mm) total indicator
reading AFTER tightening the eleven hex socket head
cap screws. The next two procedures are a method of
achieving the concentricity.
19. Put the metering ring on a hard flat surface. Put the
assembled metering package into the metering ring with
the commutator cover down, so the drive plate is par-
tially out of the metering ring (Fig. 81). (A suitable wood
block under the metering package will hold it in this
position.) Put one piece of 0.007 in. (0.18 mm) shim
stock approximately 0.5 in. (12 mm) wide and 1.5 in.
(38 mm) long between the metering ring and drive plate
in three places approximately equal distance around the
outside diameter of the drive plate.
