DRIP PAN
20. Remove the street elbow (799G) from the drip pan
nipple, then the screws (799H) and washers (799I)
that secure the drip pan (179) to the bearing housing
(134C). Pull the drip pan from the bearing housing,
see Fig. 43.
BEARING HOUSING
21. Before removing the bearings carefully remove the
labyrinth seals from the outboard and inboard
positions (332, 333). Use a sharp edged tool or
screwdriver to remove them from the bearing
housing. Be careful not to damage the shaft (122)
or seat, see Fig. 44.
22. Lift the bearing housing up vertically by the drive end
using an eyebolt and chain. Be careful not to
damage the impeller end of the shaft. Place the
bearing housing on a bench or stand so that the
shaft protrudes down through it. At this time,
remove the screws (799F & 370Y) that secure the
front (239B) and rear feet (239A). Remove the
screws (788Z) that secure the thrust bearing retainer
(119C) to the bearing housing. Remove the retainer
and discard the gasket/shims (331) or o-ring (412Y),
see Fig. 45.
23. Using the eye bolt already threaded into the shaft,
pull the rotating assembly from the bearing housing,
see Fig . 46. Once the rotating assembly has been
removed place it on a set of wooden V-blocks for
bearing removal, see Fig.’s 47 and 48.
ROTATING ELEMENT
1MXR-3MXR Configurations:
24. In order to remove the bearings first pry the tangs of
the lock-washer (382) from the lock-nut (136). Then,
using a spanner wrench remove the lock-nut (136)
and lockwasher (382). This thrust bearing
configuration consists of two back to back angular
contact bearings. Use a bearing puller to remove
both thrust bearings (112C). Finally, use a puller to
remove the inboard radial bearing (168C) from the
opposite end of the shaft. Be careful not to damage
the shaft, see Fig. 47.
