AHM / Rivarossi / IHC CLOSE COUPLING  Adapter [ HO ]

This is a repair part for a broken coupler boss (on the above trucks)

The Boss1 may also be used as Close-coupling Adapter for AHM, Rivarossi, IHC Passenger Car Trucks

Miscellaneous Railroad Company Boss1

The Passenger cars couple much closer together and can still navigate turns and crossovers

The illustrated cars are on a 24 inch radius curve.

The test layout has #6 crossovers.

McHenry MCH-52 was used on the modified passenger car trucks.

The Coupler-Boss1 installed shortens the coupler length ≈ 2.85mm

Overall reduction of 2 modified cars is 5.7mm.

Installation is fairly straight-forward.

After removing the trucks, remove the wheels, and then break-off the coupler boss

Trim the remaining void with a hobby knife to make the hole rectangular.

Glue the Boss1 into the void with a cyanoacrylate based adhesive.

On our test cars, the brake shoes were bent out a tad and reinstalled 33 inch metal wheels (4-wheel trucks)

This raises the car 0.023 inches ( 1/64^th inch = 0.0156 inches )

The test IHC 85ft heavyweight car has 36 inch wheels reinstalled into the trucks

The Boss1 was originally invented to repair the IHC 3-axle truck as reflected in the label.

Time to “ROCK and ROLL”! . . . Mostly Roll!

I attempt to provide the most accurate description possible.

My intention is to prevent any surprises.
