place the HGF unit, input

the service assembly fixture.
Attach the unit to the fixture
with four 5/16-24 UNF nuts.
See FIGURE 4.

disassembly of HGF unit, study the

grooves on the side of the components
in the assembly. Also, note the jacket
tube contact brush cover hole radial
position relative to the side of the unit
with the alignment grooves. The
relative alignment groove positions on
the components and the jacket tube
contact brush cover hole positions
must be maintained at reassembly.
Refer to the alignment groove graphic
on fold-out.
