Grandt Line Shay and Galloping Goose drive units. These gearhead Micro-motor custom drive units are the very best drives for these locomotives but with age the plastic drive pinion on the motor shaft splits. Our SS-3037 is a machined brass collar that fits around the upper portion of the pinion and keeps it from spinning on the motor shaft even if it splits. See Supplies-Shaft Sleeves
Sunset C-16 #278 (Samhongsa) This was the first On3 locomotive produced by Samhongsa and he tried to use the HO gears and gearboxes he had. The detail is fine (soldering erratic) but the drive has to be rebuilt. Take out the old gearboxes and motor, install a PSC 4018-1 gear on the axle and reassemble wheels and rods without gearbox. Adjust quartering then get wheels to rotate smoothly (many of these locos had the 3rd to 4th driver siderod too short- if a problem, pull side rod knuckle pin, oval hole in 3rd siderod and solder pin in at proper position for proper rod length). When smooth add gearbox and silicone Glide Drive A-22 in the firebox aligned with worm shaft. Save old gears, see HO Sunset GN O-1.
Balboa C-19 also PSC C-17/C-19(Katsumi). These were really nice models, the PSC rerun of the Balboa had hundreds of extra details and was superb but the can motor used was very noisy and "coggy". Simply putting a mounting floor in the firebox and siliconing in a Glide Drive A-22 makes these superb running locos.

PFM/PBL C-16 #223.(S. Kodama) Nice model just before can motors. Just opening the motor slot in the bottom of the boiler up a bit with files or Dremel will allow a FM-1430 and FW-160820 flywheel to be fitted and performance is improved 200%.
