Base plate Assembly Procedure
Refer to Base Plate Assembly, page 26.
1. Clean all base plate components.
2. Note: Make sure the bearings and their inner
races are kept as a matched set.
3. Inspect all bearings, shafts, helix pin carrier and
gears for wear, debris and discoloration from heat.
Replace as needed.
Replace the roller bearings
and the inner races on each shaft as a set (both
bearings on the shaft) as needed. Replace the
helix carrier ball bearings as a set at each
complete disassembly or rebuild. Replace all
seals and gaskets removed at each disassembly
or inspection.
4. Install the input shaft cover seal (#5) into cover (#19).
5. Press the roller bearings (#14) into all four of the
covers (#17, #18 & #19).
Note: Make sure the
bearings and their inner races are kept as a
matched set.
6. Install the hex head flange screws (#39) and washers
(#42) into the shaft bearing covers using LOCTITE
#243 thread locker sealant.
7. Install the plastic plugs (#2) in the threaded holes
used to press the covers out of the base plate.
8. Install the key (#12) into the idler shaft (#24).
9. Align the idler gear (#21) with the key (#12) and idler
shaft (#24) 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.
10. 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.
11. Place the idler shaft and gear assembly into the base
plate 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).
12. Install the idler shaft covers (#18) on the pulley side,
and (#17 on the hydraulic side). Secure each cover
with four hex head flange screws (#44) 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
.
13. Install the 90 degree fitting (#6) containing the roll pin
(#37) into the bearing cover (#17) using LOCTITE
#565 sealant on the threads.
Make sure the port for
the breather faces the top of the base plate
housing.
14. Install the breather (#4) into the 90 degree fitting (#6).
15. Install the exciter weights (#25) on the idler shaft
(#24) and secure with four socket head cap screws
(#45) 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 (#22). 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 (#20) onto the input shaft (#22)
and slide to the end with the bearing inner race.
18. Press the other bearing inner race onto the input
shaft (#22).
