3. Verify the combined weight of the pump and hoses filled with hydraulic fluid do not
exceed the PTO manufacturer’s weight restriction. If the pump weight does exceed
this restriction, the installer has two options: A) a bracket to support the pump can
be implemented, or B) the pump can be mounted to the vehicle chassis, connected
to the PTO with a drive shaft.
4.
Verify that the pump shaft will mount to the PTO. Pumps supplied by Smart Power
®
Systems have an SAE B 2 bolt flange. The standard pumps supplied by Smart
Power
®
Systems have either a SAE B 7/8” 13 tooth spline for Models ER-6.2, ER-8
and ER-10; OR a SAE B-B 1” 15 tooth spline on the ER-110 model.
Upon special order, a 1” keyed shaft is available on Models ER-6.2, ER-8 and ER-
10. A 1 ¼” keyed shaft is available on the ER-110 Model. Check the PTO
manufacturer’s specification to verify that the pump supplied with the system will
mount to the PTO installed on the vehicle.
Note: In some cases it may be necessary to mount the pump remote from the PTO
and drive it with a drive shaft. Contact the PTO manufacturer for information on the
proper mounting configuration under these conditions.
WARNING:
The installer must provide guarding to prevent damage to the pump seals from road
debris if the pump is remotely located. Also, properly sized and installed vibration
isolators must be used if the pump is mounted to the chassis. Failure to do either
will void the system’s warranty.
Never use an unbalanced drive shaft to drive a remotely located pump. An
unbalanced drive shaft will cause premature wear of the pump and will void the
system’s warranty.
Do not approach a running A.C. modular generator when wearing long, loose items
such as hair, jewelry, ties, clothing, etc. Direct contact with a rotating drive shaft
can cause serious personal injury and/or damage to the system.
5.
Obtain the following hoses of the necessary length for the installation:
a) Pump inlet hose: 1” SAE 100R1AT-16 hose (use Parker hose ends P/N 10643-
16-16). Note: Maximum hose length is 20’.
b) Pump outlet hose: 1/2” SAE 100R9AT-8 rated to 4000 PSI (use Parker hose
ends, part number 10643-8-8). Note: Maximum hose length is 20’.
c) Pump case drain hose: 5/8” SAE 100R1AT-10 (use Parker hose ends, part
number 10643-10-10). Note: Maximum hose length is 20’.
