5. Install the hex head screws (#23) and washer (#26)
into the shaft bearing covers using LOCTITE #243
thread locker sealant.
6. Install the plastic plugs (#1) in the threaded holes
used to press the covers out of the baseplate.
7. Install the key (#12) into the idler shaft (#8).
8. Align the idler gear (#11) with the key (#12) and idler
shaft (#8) and press the idler gear onto the idler shaft
using exciter oil as a lubricant. Reference the figure
5 for the idler gear and shaft orientation.
9. Press the bearing inner races onto the idler shaft/
gear assembly. The flanged end of the inner race
goes toward the shoulder on the shaft.
10. Place the idler shaft and gear assembly into the
baseplate housing in the forward location. Note: The
housing is not symmetric. The input/pulley side
of the housing has a pocket machined for the belt
bellows. This pocket is to be oriented toward the
front left side of the machine. The end of the idler
shaft with the hole goes toward the front right
side of the machine with the breather/cover (#17).
11. Install the idler shaft covers (#7 on the pulley side,
and (#17 on the hydraulic side). Secure each cover
with four hex head flange screws (#25) using
LOCTITE #243 on the bolt threads and torque the
flange screws to 13 ft.-lbs. See the figure #3 for
LOCTITE #515 gasket maker application. Check
idler shaft for minimum of .020” end play after
covers are installed and the bolts are torqued.
12. Install the 90 degree fitting (#2) containing the roll pin
(#22) into the bearing cover (#17) using LOCTITE
#565 sealant on the threads. Make sure the port for
the breather faces the top of the baseplate
housing.
13. Install the breather (#3) into the 90 (#2) degree fitting.
Make sure breather is clean, functioning & air can
pass thru, if unsure replace breather.
14. Install the exciter weights (#21) on the idler shaft (#8)
and secure with four socket head cap screws (#27)
using LOCTITE #243 thread locker sealant and
torque the cap screws to 32 ft.-lbs.
15. 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.
16. Install the input gear (#10) onto the input shaft (#16)
and slide to the end with the bearing inner race.
17. Press the other bearing inner race onto the input
shaft (#16).
18. Install the input shaft subassembly into the baseplate
with the keyed end toward the left side (pulley side)
of the base plate.
19. 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.
20. Secure the input shaft cover with the four flange head
crews (#25) using LOCTITE #243 thread locker
sealant on the bolt threads and torque the capscrews
to 13 ft.-lbs.
21. Install the other input shaft cover (#9) to base plate
and secure with the four flange head screws (#25)
using LOCTITE #243 thread locker sealant and
