Important:  The motor shaft must be vertical when the check balls are
installed.  This will insure that they seat properly (see Figure 27).

68  Install the two check ball plugs with new o-rings and tighten them
to 6,8-12 Nm [5-10 lb-ft].

Wheel Motor

A different bearing housing is used on wheel motors (see Figure 28).
Other than this the parts are the same and the same disassembly/
reassembly procedures apply.

Bearingless Motor

Bearingless motors are the same as standard motors without the shaft/
bearing assembly, and thrust bearings. The mounting flange replaces
the bearing housing and wear plate (see Figure 29).
