8. Once the HPTO housing is piloted and
flush with the engine housing, you can
remove the crane support.
9. Install customer supplied sheave and
QD bushing to the output shaft of the
HPTO. Insure that belts (once
installed) will be aligned and track
straight.
10. Tension Belts according to Equipment
Manufactures specifications.
11. Install proper safety guards (not
supplied by PT Tech®).
12. The Manifold Assembly has been
preinstalled on the HPTO Clutch at the
factory. Do not remove the manifold
unless rebuilding the HPTO unit. See
manifold drawing provided for hose
fitting sizes and connection locations.
13. Install the Microprocessor Controller
and all electrical wiring per the
Controller I&M Bulletin.
Hydraulic Instructions
Refer to the manifold and hydraulic
schematic provided for all hydraulic
connections.
14. All hoses must be thoroughly flushed.
All hoses should be ½” diameter
minimum that are connected to the
“inlet” and “tank” ports on the manifold.
(All hose is customer supplied.)
15. Connect all hoses per the hydraulic
schematic provided at the end of this
document.
16. Insure that the hydraulic fluid reservoir
is filled to the proper fluid level.
17. Insure that there is a clean 15-micron
minimum oil filter in the hydraulic
system.
MAINTENANCE INSTRUCTIONS
The HPTO requires simple routine
maintenance by maintaining the proper oil
level in the hydraulic reservoir and
replacing the oil filter when required by the
equipment manufacturer. Maintenance
and inspections should be performed as
follows.
Daily Inspection:
The following items should be checked
daily.
1. With the clutch disengaged and the
ENGINE OFF in a cooled condition, the
oil level indicator on the oil reservoir
should be visually checked to insure
that the oil level is at the proper level. If
needed, add additional oil to the
reservoir.
500 hours of operation:
The following items should be checked
after the first 500 hours of operation and
every 500 hours after that:
1. Check all HPTO bolted connections
and hydraulic connections.
2. Change the equipment system oil and
filter per equipment manufacturer’s
recommendations.
5000 hours of operation:
The HPTO unit must be serviced and
inspected after 5000 hours of operation. If
the HPTO unit is allowed to operate
beyond this point, the torque may drop
rapidly and possible damage to the unit
could occur.
