9.0 Care and Maintenance – [cont’d]
9.7.3 Bearing Replacement
IMPORTANT
Use only genuine Allied replacement parts to
protect total warranty coverage. Non-approved
parts may impair performance or reliability.
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
disassemble and assemble the Ho-Pac.
Questions regarding maintenance, repair or operation
can be directed to Allied Technical Service. For
questions regarding replacement parts, contact
Allied’s Customer Service.
9.7.4 Bearing Removal
1. Remove hydraulic motor.
2. Remove the motor side bearing housing from the
eccentric housing.
3. Remove the eccentric mass.
4. Remove the other bearing housing.
5. Press bearing out of housing. Ensure 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.
IMPORTANT
Obey all local regulations for the proper disposal of
all used fluids.
9.7.5 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 bearing’s outer race.
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 bolts.
8. Install hydraulic motor and bolts.
9. Install hydraulic hoses.
9.8 Spring Mounts - Replacement
The spring mounts are subject to aging and require
periodic replacement. While spring life depends
primarily on use, other factors, such as extreme
environmental conditions can also shorten spring life.
Due to vibration and shock loads experienced by the
Ho-Pac, all threaded fasteners must be checked
frequently for loose, broken or missing bolts.
CAUTION
Some components of the Ho-Pac are heavy. Use
approved lifting equipment to properly support and
stabilize loads.
CAUTION
Crush injury. Do not place hands or
fingers between mounting frame and
compaction plate during removal of
spring mounts.
Ensure all loads are adequately supported before
performing any service work.
