The EN87 features the same coupler head design used in the popular EC87 coupler. However, these couplers have a shank narrow enough to be used in true scale size draft gear boxes. Couplers are supplied with highly prototypical Accurail® PROTO HO scale size draft gear boxes and mounting screws.
The EN87 is a screw-on upgrade for the traditional knuckle couplers included
on many recently released HO scale cars and locomotives. To find out if a particular car
will easily accept the EN87 draft gear box, temporarily remove the wide factory
installed box. Cars that are easily adaptable to the EN87 will have a total of
three holes for draft gear box mounting. The larger center hole is used for the
mounting of the wide "standard" draft gear box that the car probably came with
from the factory. Many recently released models also have two additional smaller
holes. The Atlas® reefer shown here
is an example of such a model.
These smaller holes are used to mount the more prototypical draft gear box supplied
with the Sergent Engineering EN87. If the draft gear box on your model is not removable,
or is an integral part of the underframe as is the case on many older models, do not
be dismayed. A Sergent Engineering EC87 type coupler will likely
drop right in to the existing draft gear box. Sergent Engineering also offers an Assembly
and Installation Toolkit to assist in retrofitting the more prototypical EN87 to any
model. Read on...
The EN87 is available in both assembled and kit form. The assembled couplers are handy if you would rather spend your modeling time doing something other than assembling couplers. The kit version is easy to assemble and a bit less expensive. Some customers report that the kit couplers they assemble operate more smoothy than our factory assembled versions.

An MS uncoupling wand is required to operate the couplers.
This wand is simply a custom made industrial strength magnetic rod which lifts the
internal steel
ball in the coupler allowing it to open. The wand has a wire attached to one end aid
in aligning couplers in preparation for a tie as well. We don't recommend
building your own uncoupling wand from magnets you may have lying around. Customers
who have tried this have reported less than satisfactory results.

The IFN Installation kit contains metal templates and an appropriate drill for accurately locating draft gear box mounting holes on rolling stock. It is intended for customers that deal mostly with the assembled EN87A product.
If you plan to assemble lots of EN87K kits or retrofitting models to accept the EN87, you'll want an AFN Assembly and Installation Toolkit. Realize that this is not the same as the AFC Assembly fixture for compatible shank couplers. The AFN toolkit contains all necessary tools to do production line type assembly of the EN87K kits. The included assembly fixture is used to hold the coupler together as it is assembled.You'll probably want a couple of extra ball and spring packets, too. Even though Sergent Engineering will gladly replace these small parts at no charge if they happen to get lost during assembly, you might want them more quickly than we can send replacements. These are cheap and nice to have on hand.

Couplers that have the cut lever attached on top are referred to
as "top operating" Couplers that have the cut lever attached at the bottom
are referred to as "bottom operating". The type E coupler
modeled by the EN87 was always available as a bottom operating coupler,
even though the top operating version seems to have been preferred initially.
Sergent Engineering offers two items to assist the modeler in adding these special
details.
The BCL87 contains 10 etched brass cut lever linkages. These linkages fit into slots on the bottom of the coupler as shown in the picture. The cut levers (not included) should be inserted through this linkage in a manner that allows the coupler to swing from side to side.
For those that desire to model top operating couplers, Sergent Engineering offers drilled top coupler castings which will accept lift rings. This option should be ordered at the same time coupler kits are ordered. Lift rings should be installed prior to assembly of the couplers since there is a risk that glue used to attach the rings may also make its way to the locking ball inside the coupler. For this reason, the drilled tops are only an option for kits - not assembled couplers.
Holes in top castings are created with a #80 drill. We recommend either bending your own eyebolts from 0.010" wire or using Grandt Line #5085 eyebolts (or #86085 if you would rather have the equivalent in brass) for this application.
