Having selected the Kadee
®
Coupler best suited for your
application, turn car over and place Coupler with Draft
Gear Box in position, directly on the car centerline. Look
for obstacles which might prevent Gear Box from laying flat
in position. (NOTE: The protruding European style bumper
cushion which some LGB™ cars have, must be removed
for proper clearance. Pulling straight out and removing half
may be enough or it should be cut off as close to the car as
possible). It might be helpful to hold the Coupler Assembly
in place & check distance from center of Coupler to top of
rail using the appropriate coupler height gauge. Once you
have established this measurement, you can determine if
you must shim Gear Box down or cut the underbody to raise
the Coupler Draft Gear Box.
If Coupler mounting surface is uneven, or too high from the
track, make one or more plastic shims to support the Coupler
Assembly. In many cases, you can place shims on, or
between, the center sills and end sills of the car underframe
to provide a solid base for the Gear Box. Temporarily mount
shims, then set Draft Gear Box assembly in place and mark
location of mounting holes on shims. Remove shims and drill
and tap for 2-56 screws in the marked locations. Remount
shims in their original position, this time using screws to hold
them solid.
NOTE:
When using metal screws in plastic, tapping of the hole is not
required. After drilling a 5/64" hole, the screw will self-tap.
If Coupler mounting surface is too low, the underframe must
be cut to raise the Coupler to the proper height. Carefully
lay out the area to be cut so the Gear Box will be level,
centered and at the correct height. It may be best to remove
most of the material with a chisel or small saw. leaving finish
material which can be carefully removed with a fine file until
desired fit and depth is achieved. Placing shims between
the truck bolster and the car body bolster to raise the car is
an alternative to cutting the car body underframe for some
cars.
The Coupler Assembly can now be screwed into place. An
alternative to tapping the mounting holes is to drill 3/32"
holes through and use 2-56 screws and nuts to secure the
Draft Gear Box. The metal screws can be cut to the required
length with a fine saw. Before cutting, screw on a supplied
nut, so that by removing it after the cutting, the nut will serve
to clean up the thread ends.
COUPLER OPERATION
TO COUPLE -
Simply push cars together until knuckles bypass each other
and lock into position.
FOR DELAYED UNCOUPLING -
1) Stop with the couplers over an uncoupler and back up
slightly with the couplers still over the uncoupler, allowing
slack to occur between couplers. 2) Pull forward slightly.
Couplers are now in the delayed position. 3) Back up,
pushing the car(s) to the desired location. Do not permit
slack to develop between couplers. 4) Pull forward, leaving
the car(s) where desired. Couplers automatically return to
normal coupling position.
Use Kadee
®
Greas-em, the dry lubricant recommended for
use with all Kadee
®
Magne-Matic
®
couplers. Grease-em will
not attract the dirt and dust that gums up the inside of couplers
like oil, grease or other lubricants will. Use our #829 #1-Scale
or #880 G-Scale Height Gauge to check for the correct coupler
height and trip pin clearance. The N.M.R.A. standard for
coupler height is the centerline of coupler is 1 1/16” (1.0625”)
for #1-Scale & 1 1/8” (1.125”) G-Scale.
Note: If couplers swing open too far when
uncoupling, lower magnet slightly to correct.
Note: We include extra knuckle springs. The Replacement
Knuckle Spring used on Kadee
®
#1-Scale couplers are sold as
the #875 (#8
20
-828 couplers) or #1875 (1700 & 1800 series
couplers) Knuckle Spring. The Knuckle Spring used on Kadee
®
G-Scale couplers are sold as the #860 Knuckle Spring.
For Delayed Action Uncoupling use our #842 Uncoupler,
#844 Portable Uncoupler, or our #840 Uncoupler mounted
in LGB track.
