Note: One of the gear boxes has a large hole in
the shank and the other has been machined at an
angle on the shank. The coupler with the medium
offset is used with the draft gear box that has the
large hole located in its shank and will be mounted
at the front of the locomotive. See Fig.1. The coupler
with the large offset is used with the draft gear box
that has been machined and is to be mounted at the
rear of the locomotive. See Fig.2. When working on
locomotives or cars they must often be turned upside
down or on their sides. Always place a protective mat
underneath them, and protect any protruding detail
parts which could be damaged. Remove any flash or
burrs from parts with a file or an X-acto
®
knife.
Mounting
Front coupler:
1. Remove the old existing coupler.
2. Refer to the exploded view in Fig.3 to familiarize
yourself with coupler mounting parts and installation
positions. There are two large diameter washers in
this packet, one (1) thick and one (1) thin. Place the
thin washer onto the locomotive's coupler mounting
post and slide it down until it rests on top of the three
gussets located on the post. If the washer does
not slip onto the coupler mounting post there may
be excessive paint on the post. This paint can be
removed by scraping the post with an X-acto
®
knife.
The washer should not fit too loosely.
ASSEMBLY
iMPoRtAnt: Before assembling remove any
burrs or flash (if any) from all parts. Burnish
(Polish) all friction bearing surfaces with #231
greas-em dry graphite lubricant.
To assemble the coupler follow the illustrations in
these instructions. Make sure the gear box lid is
tightly secured with the screw. Add a “puff” of our
#231 Greas-em into the draft gear box. Make sure
the coupler flexes back and forth freely.

3. Slip the assembled coupler unit through the
opening of the locomotive pilot and tilt the coupler
unit at a slight angle to position the large hole in the
draft gear box shank over the mounting post. Slide
the shank down the post to rest on the thin washer
and then level coupler unit.
4. The thick washer can now be placed on the post
and over the previously installed draft gear box
shank.
5. Position the flat angle spring over the thick washer,
centering the hole in the spring leg over the original
coupler mounting screw hole in the post. Make
certain that the other spring leg is pointing down
behind the end of the draft gear box shank.
6. Place the small washer on top of the flat angle
spring and secure with the original coupler mounting
screw that was removed previously, Make certain
that the draft gear box is centered in the locomotive
pilot opening while tightening the mounting screw.
7. Test the centering action of the draft gear box; it
should move freely from side to side and re-center
itself. If the coupler unit does not center properly, it
may be helpful to loosen the mounting screw and
push slightly forward on the back leg of the flat angle
spring while retightening the screw. If the flat angle
spring does not tighten down properly, remove and
file one or both of the large washers until it will do so.
If more side swing of the coupler is desired, the sides
of the draft gear box or pilot opening at the front of
the locomotive can be modified by carefully cutting
or filing away the excessive material that interferes
with the desired swing. Caution must be exercised
against removing to much material. This would
impair the performance of the coupler.
