13. Install the 90 degree fitting (#2) containing the roll pin
(#20) into the bearing cover (#18) using LOCTITE
#565 sealant on the threads. Make sure the port for
the breather faces the top of the baseplate
housing.
14. Install the breather (#3) into the 90 (#2) degree fitting.
15. Install the exciter weights (#17) on the idler shaft (#8)
and secure with four socket head cap screws (#24)
using LOCTITE #243 thread locker sealant and
torque the cap screws to 32 ft.-lbs.
16. Press one bearing inner race onto one end of the
input shaft (#16). Note: Make sure the bearings
and their inner races are kept as a matched set.
The flange on the inner race goes toward the
shoulder of the shaft.
17. Install the input gear (#10) onto the input shaft (#16)
and slide to the end with the bearing inner race.
18. Press the other bearing inner race onto the input
shaft (#16).
19. Install the input shaft subassembly into the baseplate
with the keyed end toward the left side (pulley side) of
the base plate.
20. Install the pulley side shaft cover (#9), containing the
shaft seal (#5) over the input shaft on the pulley side
of the baseplate. See the figure #3 for LOCTITE
#515 gasket maker application. Lubricate the
input shaft seal and bearing with exciter oil
before inserting the input shaft through the oil
seal in the cover to prevent tearing the seal.
21. Secure the input shaft cover with the four flange head
crews (#23) using LOCTITE #243 thread locker
sealant on the bolt threads and torque the capscrews
to 13 ft.-lbs.
Refer to LOWER SHAFT ASSEMBLY, page 26.
22. Install the other input shaft cover (#12) and secure
with the four flange head screws (#22) using
LOCTITE #243 thread locker sealant and torque the
screws to 13 ft.-lbs. See the figure #3 for LOCTITE
#515 gasket maker application. Check input shaft
for minimum of .020” end play after covers are
installed and the bolts are torqued.
23. Install one exciter weight (#17) to the input shaft on
the hydraulic housing side of the baseplate with two
socket head cap screws (#24) using LOCTITE #243
thread locker sealant and torque the cap screws to 30
ft.-lbs. Be careful to use a small amount of thread
locker to avoid dripping it into the helix pin carrier
bearings at installation.
24. Slide the input gear (#10) toward the pulley side of
the input shaft (#16). The gears should not be
meshing at this time.
Refer to LOWER SHAFT ASSEMBLY, page 26.
25. Install the ball bearings (#3) and the spacer washer
(#7) onto the shift shaft (#10) and secure with the e-
clip (#5).
26. Press the shift shaft and ball bearing assembly into
the helix pin carrier (#9) and secure with the internal
retaining ring (#8).
27. Lubricate the helix pin carrier/shift shaft assembly
with exciter oil and slide into the input shaft and install
the dowel pin (#11).
Note: Helix pin carrier MUST slide freely in input shaft.
28. Slide the helix pin/carrier to the middle of the helix
and orient the dowel pin parallel with the bottom of
the baseplate housing (#15).
