Because the Ho-Pac is a vibratory tool, it is
extremely important that threaded fasteners
are properly tightened. Always follow the
torque specifications in this section.
!! CAUTION !!
Replace any damaged fasteners prior to
Ho-Pac operation. Use only Allied
replacement parts.
1. Clean threaded fasteners and surfaces to
be bolted.
2. Apply a light coat of grease to threads
and washer faces (except for base plate
bolts).
3. For base plate bolts only, apply a
commercial grade, thread adhesive. Follow
manufacturer’s recommendations.
(Example: Loctite 271 Thread Adhesive-
Sealant)
4. Initially tighten the bolts to 10 ft-lbs (14
N-m).
5. Tighten the fasteners according to the
table below.

11.7 Bearing Failure & Replacement
Because of the high loads and rotational
speeds, bearing failure is usually sudden.
A scraping or rattling sound is an
indication of imminent bearing failure.
Visually inspect the bearings for broken or
damaged components to determine if
replacement is necessary.
Bearing service shall be performed in a
properly equipped workshop. Use of a
manual arbor press is recommended. Do
not attempt to replace bearings in the field.
!! CAUTION !!
Use only Allied replacement parts.
11.7.1 Bearing Removal
1. Remove hydraulic hoses from motor.
2. Remove the hydraulic motor, gasket,
and spacer.
3. Remove both bearing housing
assemblies from the main housing. It is not
necessary to remove eccentric from main
housing.
!! WARNING !!
Be careful that eccentric shaft does not
fall and injure hands or fingers.
4. Remove the bearing from the bearing
housing by pressing on the bearing inner
race from the interior side of the bearing
housing. Properly support the bearing
housing in the press.
5. If the outer race remains in the housing,
do not pry out. Carefully place a small
bead of weld, 1/8 inch (3 mm) along the
inside diameter of the outer race. Allow the
weld to cool. The outer race can easily be
removed.
