Maintenance
NOTICE:Use an induction heater that heats as well as demagnetizes the bearings when you
install bearings. Failure to do so may result in decreased performance.
1. Prepare the bearing frame (228) as follows (see the illustration):
a) Install the oil-fill plug (113A).
b) Install the oil-drain plug (408A).
c) Install the sight glass (319).
d) Install the sight oiler plug (408J).
e) Install the plug for the oil-cooler inlet (408L).

Or: Install two grease fittings (193) and two grease-relief plugs (113).
2. Install the outboard bearings (112A) on the shaft (122).
The regreasable bearing has a single shield. Make sure that the bearing is installed with the
shield away from the impeller.
The duplex bearings are mounted back-to-back. Make sure that the orientation of the
bearings are correct.
a) Inspect the shaft (122) to ensure that it is clean, dimensionally correct, and is free of
nicks and burrs.
b) Lightly coat the bearing seating with a thin film of oil.
c) Remove the bearings (112) from their packaging.
d) Wipe the preservative from the bearing (112) bore and outer diameter.
e) Use an induction heater with a demagnetizing cycle to heat both bearings (112) to an
inner ring temperature of 230 °F (110 °C).
f) Place both bearings (112) on the shaft (122) with the large outer races together (back-
