9.0 Care & Maintenance - [cont’d]
9.5.5 How to Drain Oil
1.
Position the Ho-Pac upright on a level surface
with easy access to both the oil fill and oil level
plugs. Refer to Figure 9-2.
2.
Clean area around the oil level and fill plugs.
3.
Loosen, but do not remove the plugs.
4.
Point the plug downward so that oil will drain.
5.
Place a suitable container to catch oil.
6.
Remove oil level plug. Drain all oil.
IMPORTANT
If the oil is contaminated with water or dirt, flush the
eccentric housing with clean oil prior to oil
replacement. Properly dispose of used oil. Obey all
local regulations for the disposal of these fluids.
7.
Fill with new oil to proper level. Do Not Overfill.
Use correct type.
9.6 How to Check Condition of Bearings
Due to the high loads and rotational speeds, bearing
failure is usually sudden. A rattling or scraping sound
is a tell-tale sign of imminent failure. Visual inspection
of bearing requires removal of the bearing housing.
9.6.1 Bearing Replacement
IMPORTANT
When repairs are made, use only the manufacturer's
genuine parts. Substitute parts may not meet the
required standards for fit and quality, or may impair
function, safety and performance.
IMPORTANT
Bearings are interference press fit into housing.
Replacement requires a workshop equipped with a
manual arbor or hydraulic press.
Use standard mechanic’s techniques and tools to
replace bearings. Questions regarding maintenance,
repair or operation can be directed to Allied Technical
Service.
IMPORTANT
Obey all local regulations for the proper disposal of
all used fluids.
9.6.2 Bearing Removal
It will be necessary to remove the following items to
access the bearing: Hydraulic motor, Bearing
housing, Eccentric mass, 2
nd
bearing housing.
1.
Ensure the bearing housing is properly supported
and press only against the bearing’s inner race.
CAUTION
Crush injury. Eccentric mass is heavy.
Handle carefully to avoid injury to hands
or fingers.
IMPORTANT
Do not pry out the outer bearing race if it remains in
the housing. Place a small weld bead, @1/8 inch (3
mm) along the inside diameter. When cool, remove
the outer race.
9.6.3 Bearing Installation
IMPORTANT
Handle new bearings with care to prevent damage.
Do not remove from packaging until ready to install.
CAUTION
Bearings are interference press fit. Apply contact
pressure to the outer race only. Do not hammer on
the bearing rings.
1.
Clean the bearing housing.
2.
Lightly lubricate outer race of bearing.
3.
Slowly press bearing into housing.
4.
Clean and lubricate the eccentric shaft.
5.
Slip bearing/housing onto shaft.
NOTE
: Close
tolerance slip fit.
6.
Repeat steps 1-4 with other bearing and housing.
7.
Install the bearings and eccentric in to the
eccentric housing. Install and tighten bolts.
IMPORTANT
Apply thread locker to bearing housing bolts.
8.
Install hydraulic motor and bolts.
