24. Install retainer in the back of the inner race of one
of the thrust bearings. The back of the inner race is
the narrower of the two sides.

the housing first, retainer towards the support.

sides of the inner races are placed together. A light
application of clean compressor lubricating oil
should be used to ease the installation of the bear-
ings into the gaterotor support.
