10.3 Preventative Maintenance
After every 100* hours of Ho-Pac operation,
inspect the following:
Check oil level (Model 300 only)
Check components for excessive wear.
Check spring mounts for cracks in
rubber.
Check threaded fasteners. Replace any
that are missing or damaged. Check
fasteners for tightness. Refer to Section
10.12 for bolt torques.
After every 1000* hours of Ho-Pac
operation, replace the oil (300, 500 only)
*The frequency of maintenance depends
upon the operating environments and
conditions of operation. For additional
maintenance considerations, refer to
Section 10.5.
10.4 Threaded Fasteners
IMPORTANT
Keep fasteners tight. Replacement
fasteners must be the same type and
grade.
Tighten the fasteners according to Table
10.1.
NOTE
: After bolt installation, operate the
Ho-Pac for a few hours, then re-check bolt
torques.
10.5 Conditional Maintenance
While the frequency of inspections and
maintenance depend primarily on use, other
factors such as extreme environmental
conditions require additional measures.
Clean all Ho-Pac working surfaces under
the following conditions:
Extremely humid weather conditions.
Muddy or extremely wet soils.
If reduced performance is observed.
10.6 Pressure Relief Plug (300 & 500)
The eccentric housing is equipped with a
pressure relief check valve. This check
valve is located near the top of the eccentric
housing and relieves pressure from the
eccentric housing. A slight amount of oil
residue in this area is normal.
10.7 Lubrication (300B & 500B)
Bearings used in the 300B & 500B models
are lubricated for life and sealed. Sealed
bearings eliminate daily greasing and
protect against contamination related
failures.
10.7.1 Lubrication (300 & 500)
During operation, the bearings used in the
models 300 & 500 are continuously
lubricated from an oil bath within the
eccentric housing.
