Place Draft Gear Box Lid on box, being careful not to dislodge

Centering Spring, then slip tweezers out. While holding lid in

place, test coupler centering action by toggling it back and forth.

Coupler should move freely and automatically snap back into

center position. If it does not, disassemble coupler, check for

proper spring seating, then reassemble.

MOUNTING:

Place the flex bracket In the proper location shim if necessary

and mark through the screw holes. Remove the flex bracket

and drill clearance holes (3/32”) through the underbody. The

flex bracket is now secured using the 2-56 screws and nuts

supplied. (Fig.7 & 8)

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.

Note: We include extra knuckle springs. The Replacement

Knuckle Spring used on Kadee

#1-Scale couplers are sold as

the #875 (#820-828 couplers) or #1875 (1700 & 1800 series

couplers) Knuckle Spring. The Knuckle Spring used on Kade

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.

coupler conversion list & coupler conversions are

on the Kadee

web site for your connivance.

Note: Kadee’s® #1020 tweezers are very helpful for holding the

2-56 nuts in position Inside the car.

For some unusual mountings or if there is a clearance problem in

the mounting screw area (perhaps with the axle) the flex bracket

can be installed upside down. In this case the supplied shim is

used. The mounting area can be cut out for clearance (Fig.9).

This method of mounting will lower the coupler.

Note: If couplers swing open too far when

uncoupling, lower magnet slightly to correct.

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.
