SPLIT-SHAFT PTO GEARBOX
INSTALLATION MANUAL 12
pressure of 500 PSI (34 BAR), from the water
pump discharge to the gearbox cooler inlet
fitting.
10. Connect 3 /
8
inch (10 mm) diameter
tube, with minimum working pressure of 500
PSI (34 BAR), from the gearbox cooler outlet
fitting to the water pump suction.
CAUTION: Gearbox oil cooler and
associated tubing must drain during
cold weather to prevent damage to the
cooler and tubing from freezing.
11. Unless the gearbox cooler is attached to
the apparatus engine cooling system, install
water drains in the gearbox cooler lines.
12. Remove the 1-¼ inch long cap screw
and washer from the end of the auxiliary
output shaft(s).
13. Place the auxiliary equipment drive
adapter on the auxiliary output shaft(s).
Secure in place using the washer and 1-¼
inch long cap screw.
14. Torque the cap screw to 50 lb-ft (68 N-m)
and lock in place by applying Loctite #242,
or equal, thread locking compound to the
threads.
15. Connect the auxiliary equipment to the
drive adapter in accordance with drive
component manufacturer instructions.
CAUTION: Make sure interlocks and
indicator lights required by NFPA
standards are properly installed.
WARNING: Any electrical system has the
potential to cause sparks. Take care to
eliminate explosive or hazardous
environments during installation or
service.
16. Mount the indicator lights in the driver
compartment and on the pump operator
panel. A typical shift switch and indicator
light wiring diagram is provided as figure 6.
NOTE: The gearboxes are equipped with
two shift switches.
One of the shift switches must be used to
control ONLY the “ENGAGED” indicator light
in the driver’s compartment.
CAUTION: DO NOT exceed the rated
current of the shift switch, 4 AMPS at 12
VDC, when connecting other devices.
The other switch can be used to energize
relay coils providing circuit completion for
other apparatus interlocks such as
transmission lockup, parking brake
engaged, OK to OPERATE indicator light,
etc. DO NOT use this switch to achieve
these interlocks directly as the current rating
of the switch may be exceeded.
