36. Lubricate the inside of the hydraulic housing (#16)

and the seal lips with hydraulic oil. See Maintenance
section for hydraulic fluid type.

37. Install the hydraulic housing over the hydraulic seals

and guide ring. Be careful not to damage the guide
ring and hydraulic seals during installation.

38. Secure the mount plate (#20) over the hydraulic

housing (#16) to the input shaft cover (#12) with the
four flanged cap screws (#22) using LOCTITE #243
thread locker sealant on the threads and torque the
cap screws evenly in stages to 13 ft.-lbs.

Make sure the bleeder screw port (#14) is in the vertical

position.

39. Install the gasket (#18) and cover (#19) to the

hydraulic housing (#16) with four hex head flange
screws (#21) using LOCTITE #243 thread locker
sealant on the threads and torque the cap screws to
76 in-lbs.

40. Install the bleeder screw (#14) loosely into the port

fitting of the hydraulic housing.

41. Install the socket head pipe plug (page 22, #28) into

the oil drain port using LOCTITE #565 pipe sealant.

42. Pour in the exciter oil. Use only MBW Ground

Pounder Exciter Oil. The amount of exciter oil
required is shown in the FLUID LEVELS section
of this manual.

43. Install the baseplate cover (#13) using LOCTITE

#515 gasket maker on the lip of the mounting surface
and secure with twenty hex head flange screws (#24)
using LOCTITE #243 on the threads. See the figure
#4 for LOCTITE #515 gasket maker application.

44. Install the key (#6) into the input shaft (#16).

45. Install the pulley (#20) with the longer hub shoulder

toward the baseplate housing.

46. Install the pulley mount washer (#14) and secure it to

the input shaft with the hex head flange screw (#24)
using LOCTITE #243 thread locker sealant on the
threads.

47. Install the bushings (#19), extension plates (#18),

and socket head cap screws (#29) to the sides of
baseplate housing using LOCTITE #767 antisieze
compound on the bushings and bolt threads

Refer to Main Assembly, page 20.

48. Install the bellows (#3) into the bellows mount plate

(#10) and secure it to the baseplate with four hex
head flange screws (#22). Note spacer washers
(#27) between plates (#10).

49. Connect the hydraulic line (#16) to the 90 degree

fitting on the hydraulic housing( page 24 #16).

50. Install the grommet (#2) into the hydraulic guard (#9).

51. Guide the hydraulic line(#16) through the grommet

(#2) in the hydraulic guard (#9) and secure the guard

to the hydraulic side of the baseplate with the four hex
head flange screws (#21). Set the side cover (#12)
off to the side until bleeding and final assembly is
done. The exciter is now ready for final
assembly.

Control Head Assembly Procedure

Refer to Control Head Assembly, page 28.

1.

Clean and dry all parts to be assembled.

2.

If required press the slide bushing (#4) into the
control housing (#7).

3.

Press the hydraulic seal (#5) onto the piston shaft
(#12). Be careful to orient the seal lip to face away
from the guide ring groove. Tip: Use approved
hydraulic oil to lubricate the seal inside diameter
to ease assembly. See Maintenance Section for
type of hydraulic oil.

4.

Assembly the bearing guide ring (#10) to piston shaft
(#12) groove behind the hydraulic seal (#5).

Note: Use hydraulic oil to lubricate guide ring &

hydraulic seal before assembling into control
housing.

5.

Slide the piston shaft assembly (#12) into the control
head housing (#7), being careful not to damage guide
ring or hydraulic seal when entering control housing.

6.

Install O-ring (#3) and hydraulic fitting (#1) to adapter
nut (#14).

7.

Install adapter nut assembly (#14) into control head
housing (#7).

Note: Use hydraulic oil to lubricate guide ring &

hydraulic seals before assembling into seal cap.

8.

Assemble guide ring (#11), hydraulic seal (#9) and
shaft wiper seal (#8) into seal cap (#13).

9.

Install washer seal (#2) and seal cap assembly (#13)
over piston shaft (#12) and into control head housing
(#7).

10. Install hydraulic fitting (#6) into control head housing.

Handle Assembly Procedure

Refer to Handle Assembly, page 26.

1.

Install shift linkage (#16) to control head (#9) with
shoulder bolt (#18), washer (#27) and lock nut (#26).

2.

Assemble shift bracket (#10) to shift linkage (#16)
with shoulder bolt (#18), washer (#27) and lock nut
(#26)

3.
