rotor shaft with chamfered inside diameter end facing rotor.
(c) Place oil sealring carrier installer over end of rotor shaft and against carrier with end of installer
under ram of press. Then, press carrier down tight against rotor.
(d) Install remaining oil sealring carriers on rotor shafts in same manner.
(e) Install an oil sealring in ring groove of each carrier with a pair of snapring pliers in same manner.
To avoid breaking the oil sealrings, do not spread them any more than necessary to place them
over the end of the carrier.
(f) Support one of blower end plates, inner face up, on wood blocks on the bed of an arbor press.
(g) Lubricate outside diameter of a sealring collar with engine oil; then start chamfered outside
