Ref: KD308

Permanent magnetic under the track delayed uncoupler for Kadee couplings.

This uncoupler is popular with On30 and O gauge modellers. If used for OO/HO the strong magnetic field generated may attract the steel axle in lightweight rolling stock and cause "wobble". For OO/HO the best uncouplers are the No. 321 and 322

(For O gauge 2 or 3 magnets stacked may be required - see data sheet)

Contents:
1 Magnetic Uncoupler
1 Steel Intensifier Plate.

Caution : Contains lead compounds. Keep away from food products. Keep out of reach of children.

Kadee O Gauge Couplers - Information


The main benefits of using Kadee couplers are:

Delayed uncoupling. Only Kadee couplers allow you to pull a wagon from one siding and the push the wagon to another siding and drop it at any desired position.

Much easier to remove models from the rake by hand than chain link couplings as the Kadee couplers are not interlocked.
Operating Kadee couplers

1. Stop with the Kadee couplers over an uncoupler and back up slightly with the couplers still over the uncoupler, allowing slack to occur between couplers.

2. Pull forward bringing coupler off the uncoupler. Couplers will snap to the delayed position.

3. Back up, pushing the wagons(s) to the desired location. Do not permit slack to develop between couplers.

4. Pull forward, leaving the wagon(s) where desired. Kadee couplers will automatically return to normal coupling position.
Confused by Kadee coupler numbers and terminology -You're not alone!

The good news is that's it's not as complicated as you might think.

Trip pin: The steel wire extending below the knuckle.

Knuckle: The coupling head

Shank: The arm which fits in the gear box

Gear Box: The housing for the shank and spring.

Overset/centreset/underset? This refers to the shank position. The Kadee coupler height has to be at a set height.

In O gauge, things are very straightforward. It's a case of modifying the rolling stock to ensure the Kadee coupler is at the correct height. This usually means adding a shim of plastic or brass to lower the mounting height or some slight filing to remove a little part of the buffer beam. As there is plenty of space it's quite easy and doesn't usually involve two much work. (Occaisionally the buffer beam is at exactly the right height!)

Recommendations for UK O gauge modellers:

No. 746 Long centreset coupler
No. 745 Medium centreset coupler
No. 812 Height gauge - essential
No. 811 un-coupler
No. 231 Grease-em lubricant
No. ST35 9.5mm Self Tapping screws

The fixing holes in Kadee O couplings are approx 2.1mm and the gear box is approx 5mm thick so a screw length of 9-10mm (3/8") is recommended

If you have trouble centreing the gear boxes then try using a smaller gauge screws. This will allow a little bit of play side to side.

Kadee couplers are scale models for adult collectors, they are not toys. They contain small parts and are unsuitable for childen under 14 years.
