SECTION 2.0 OVERVIEW

The Allied 4000 Series Hole-Hog is a pneu-
matically propelled, reversible, ground
piercing tool designed to pierce continu-
ous, blind horizontal, inclined and vertical
holes in compressible soils. With optional
attachments, the Hole-Hog can also be
used to install or remove rigid pipe from
the ground.

The tool consists of three primary sections:
Body/Anvil, Striker and Tail Assembly. A
simple reversing mechanism allows the op-
erator to easily change the tool’s direction
from forward to reverse.

2.1 Body/Anvil

The body/anvil forms the majority of the
Hole-Hog’s exterior. It consists of the anvil
and the body. Refer to Figure 2-1. The
body/anvil is the ground contact surface.
Wear of this component is expected and
normal. The body is internally threaded at
the rear for attaching the Tail Assembly.

The anvil is the conical surface that forms
the front of the body/anvil. The anvil is
pressed into the body, and cannot be re-
moved from the assembled body/anvil.

2.1.1 Expanded Body

As shown in Figure 2-1, some Hole-Hogs
have expanded bodies. These models pierce
a larger diameter hole through the ground.
The smaller portion of the body pierces a
pilot hole and the larger portion of the body
expands the hole.

2.2 Striker

The striker is moved by air pressure back
and forth within the body. Internally, the
striker impacts either the anvil in the front
or the tail assembly in the rear to propel
the Hole-Hog and push the ridig pipe
through the ground.

2.3 Tail Assembly

Except for the Striker, the Tail Assembly
contains all internal operating compo-
nents, including the reversing mechanism .
The external threads of the Tail Assem-
bly’s End Cap secure the Tail Assembly to
the Body/Anvil. The Whip Hose attaches to
the other end of the Tail Assembly.
Hole-Hog service and repair require re-
moval of the tail assembly to access the ser-
viceable parts.

2.4 Differences Among Models Covered

This manual covers two Allied Hole-Hog
Models: 4000 and 4001.

All information in this manual applies to
both models unless specifically noted oth-
erwise. These two models are identical ex-
cept for the Body/Anvil:

·

Model 4000 has a Standard Body.

·

Model 4001 has an Expanded Body.
