SPLIT-SHAFT PTO GEARBOX
9 INSTALLATION MANUAL
WARNING: The gearbox is heavy. When
lifting gearbox into position use proper
lifting devices to support the gearbox.
NOTE: Lock all bolts in place using
Loctite #242 (or equal) thread sealing
compound.
1. Fabricate brackets and attach to
apparatus frame at the location where the
gearbox is being mounted. When
fabricating brackets and attaching to the
frame, pay close attention to gearbox
mounting hole location, refer to figure 4 for
MGA mounting hole locations and refer to
figure 5 for RGA mounting hole locations.
2. Position gearbox at proper location on
apparatus frame. Support the gearbox and
clamp into place.
3. Apply a light coating of Loctite #242 (or
equal) thread sealing compound to the
5 /
8
-
11 UNC grade 5 mounting bolts. Insert the
5 /
8
-11 UNC grade 5 mounting bolts through
frame brackets into tapped mounting holes
on the side of the gearbox. See figure 4
and 5 for mounting hole locations. Make
sure the mounting bolts are long enough to
allow
15 /
16
inch (23 mm) thread
engagement in the gearbox housing.
4. The RGA Gearbox requires a support
bracket attached to the top of the gearbox
housing. Manufacture and install a support
bracket from the apparatus frame to the
top housing of the RGA gearbox. Apply a
light coating of Loctite #242 (or equal)
thread sealing compound to the
5 /
8
-11 UNC
grade 5 mounting bolts. Secure bracket in
place using
5 /
8
-11 UNC grade 5 bolts. Make
sure the bolts are long enough to allow 15 /
16
inch (23 mm) thread engagement in the
screw holes on the gearbox housing.
5. Attach Spicer flange yokes to the
companion flanges on the gearbox. Make
sure the flange yokes are capable of
withstanding the torque generated by the
apparatus drive line during road operations
(16,000 lb-ft (21,693 N-m) maximum).
6. Connect the sections of the apparatus
drive shaft to the flange yokes. Use only
grade 8 or better bolts when connecting
the drive line flanges together. 1600 and
1700 series flanges require
3 /
8
inch (10 mm)
diameter bolts and 1800 series flanges
require
7 /
16
inch (11 mm) diameter bolts.
7. Check and correct the following in
accordance with the apparatus and drive
line component manufacturer instructions:
a. Drive line phasing
b. Pinion angle
c. Transmission angle
d. Gearbox drive flange angles
e. Drive shaft section angles
f.
Drive line offset
CAUTION: The gearboxes are shipped
without oil. Before placing the
apparatus in service fill the gearbox to
the proper level with SAE EP90 or SAE
80W-90 gear oil.
8. Remove the ¾ inch NPT oil fill and level
plug and fill the gearbox with SAE EP 90 (or
SAE 80W-90) oil. Once the oil level is correct
(oil at the bottom of the oil fill and level
hole) replace and tighten the oil fill and
level plug.
