AF (6-36) IOM 51
4MXR-6MXR Configurations:
25. In order to remove the bearings first pry the tangs of
the lock-washer (382) from the lock-nut (136). Use a
spanner wrench to remove the lock-nut (136) and
lockwasher (382). Slide off the keyed washer
(142B). This thrust bearing configuration is an
indirectly mounted taper roller bearing. Use a
bearing puller to remove the thrust bearing (112C).
Next, remove the thrust bearing collar (443X) and oil
wheel (248). The oil wheel has one to three set
screws (222N) that hold it to the shaft (122). The
collar and oil wheel must be removed prior to
removing the inboard bearing. Finally, use a puller
to remove the inboard radial bearing (168C) from the
drive end of the shaft. Be careful not to damage the
shaft, see Fig. 48.
