2.0 PRODUCT DESCRIPTION
Enerpac BHP-series puller sets consist basically of a
handpump, single-acting cylinder, gauge, gauge
adaptor, hose, couplers and specific tools and
attachments. The pullers are designed for installing
and removing all press fitted and heat fitted parts
such as gears, pulleys, wheels, bearings, sleeves,
sprockets, pins and other stubborn parts.
The Enerpac BHP-series puller sets are available as:
Grip Puller Sets (see paragraph 2.1), Cross-Bearing
Puller Sets (see paragraph 2.2) and Multi-Purpose
Puller Sets (see paragraph 2.3).
Puller set attachments are additional parts to
increase on-the-job flexibility further with the use of
grip pullers and cross-bearing pullers. See tables D
and E on the pages 11 and 12 for the individual
components of puller set attachments.
2.1 Grip Puller Sets
The grip puller sets BHP-152, BHP-251G, BHP-351G
and BHP-551G can be used to remove and install
gears, bearings, pulleys and similar parts. See
illustration 1 on page 3: grip pullers can be used with
a double crosshead (2 grip arms) or a triple cross -
head (3 grip arms). For individual parts see table A
on page 7.
2.2 Cross Bearing Puller Sets
The cross bearing puller sets BHP-162, BHP-261G,
BHP-361G and BHP-561G can be used to remove
and install gears, pulleys, sleeves and bushings.
These pullers can also be used as bearing cup
pullers (internal grip pullers) as shown in illustr. 2 on
page 3 or as bearing pullers as shown in illustration 3
on page 3.
In situations where clearance prevents a direct
application of grip puller arms, it is possible to use the
puller in combination with bearing puller attachment
as shown in illustration 4 on page 4. Bearing puller
attachments have wedge shaped edges to place the
puller behind the hard to reach the gear or bearing.
See table B on page 9 for individual components.
