Since the only decent looking model of this engine is the AHM/Rivarossi one from the late 70's, it looks better than any of the brass versions I have seen at least. But they lack in a couple of depts, one is you cant see the headlight, and they have one speed, warp drive mode. I installed the NWSL regear set, it cuts the top speed by 65% over the factory set up. You have to swap out the worm gear and axle gear. I scibed a line in the axle and wheel face to retain the quartering when I reinstalled the drive wheel. I drove the axle from the wheel with a small punch, then did the same with the gear using a pair of plyers behind the brass gear to support it. The axle is shouldered so the gear will only go one way. The driver you remove is the one that picks up the power. The axle is lightly splined to help line up the driver when reinstalling. I drove the new NWSL gear into place using a small socket and my small brass hammer. I then lined up the scribe and did the same with the driver. After checking wheel gauge, I put a drop of ACC to lock the wheel back on the axle and set it aside to dry, the capliary action will draw the glue into the wheel/axle grove and set it tight. I then set up my plyers above the worm gear on the motor, and drove the motor shaft back out of the worm with my small punch and brass hammer. I tapped the new worm gear on the shaft and flush with the end of the motor shaft. It was nice and tight on my motor's shaft so nothing else was done with it. I put a better grain of wheat bulb directly under the headlight and painted the back of the boiler face silver, then removed the headlight lense, painted the whole inside of the head light silver, let it dry then reinstalled the headlight lense, now its much brighter. If your motor makes alot more noise going forward, reverse the two brushes as one is mesh and one is carbon, I did this and mine is much quieter now going forwards. You will find the regear, combined with the 3 pole Rivarossi motor is a nice combination and runs quite well. I also turned down my flanges on the pilot truck and drivers using my dremel and a cut off disc, running the flanges on the side of the disc with the wheels spinning or power to motor to spin the drivers. I put new wheels in the tender trucks. Now it should run good on code 80 or lower track. I did leave the driver flanges a bit deeper than RP25 to help prevent any derailments. Wish someone made a nice casting of his special whistle! Cheers Mike
