Exciter Assembly
Refer to Exciter Assembly, page 16.
1. Press a bearing (#6) into the exciter housing (#4) and
exciter cover (#8).
2. Turn the exciter housing upside down and place the
threaded end of the eccentric weight (#14) into the
bearing in the housing.
3. Apply a light coat of grease to the step of the cover
(#8) and new o-ring (#1).
4. Apply a medium strength thread lock to the threaded
holes in the cover.
5. Line up the mounting holes between the exciter
housing and exciter cover and assemble. Take care
not to cut the o-ring. Secure the cover with three
screws (#20) and fiber washers (#11)
6. Thread the shockmounts (#7) into the housing.
7. Apply medium strength locker to threads of center
shockmount and thread into eccentric.
8. Inspect the rubber seal on mount (#12). Replace if
there are any tears or wear. If the seal is in good
condition, skip to step 12.

and hold it for 10 seconds to allow the adhesive to
set.
12. Apply medium strength locker to the threads on the
end of the drive shaft (#13).
13. Position the mounting flange on the exciter assembly
so that the plug hole aligns with the set screw on the
exciter (#18).
14. Set the mounting flange in place while turning the
drive shaft clockwise to tighten into the center
shockmount.
15. Secure the flange in place with three sealing washers
(#5) and screws (#19).
16. Apply medium strength locker to the set screw (#18)
