Kadee body mounted Couplers with shortened Draft
®
Gear Boxes are used in special applications where
there is not ample room for the Kadee
body mounted Coupler with standard Draft Gear Box.
The G-scale & #1-scale couplers are available in three
variations as shown in Fig.1
Use the #837 or #1837 Coupler for installation when
the mounting surface is very low and requires using the
coupler having the greatest offset. If alterations to the
car are required, they should be done as carefully and
accurately as possible. For maximum performance, it
is important that the Coupler be mounted at the correct
height, & directly on the cars centerline. #835, #836
& #837 G-scale & #1835, #1836 & #1837 #1-scale
Couplers do not swing as far as the #830 or #820
body mounted Coupler, so they are most effectively
operated on a track with a larger radius.
Please read through instructions carefully and
completely before proceeding.

To assemble the coupler follow the illustrations in these
instructions. The gear box lid is not secured with the screw
until it is mounted. Add a "puff" of our #231 Greas-em into
the draft gear box. Make sure the coupler flexes back and
forth freely.
MOUNTING
Use the #829 #1-Scale or #880 G-Scale coupler height
gauge to determine the coupler mounting height.
