@Nortonville Phil posted:I tried the heat shrink tubing on the geared axle. I could not get it to hold. I am using the K-Line passenger car replacement 36” dia. axles for the unpowered axle. I am trying to adapt the wheels to the geared axle from the locomotive. The axles are .0935 on the majority but are turned down and knurled on the ends to 0.090 where the wheels mount. I plan to make some bushings for the wheels.
On either side of the motor block I am using a .015 thick washer. There is about 0.032 play on each side without the washer. But that is for wheelsets of the older O scale standard with thicker flanges and 1.125 back to back dimension.
Sorry it did not work for you. I just finished my 3rd conversion using it.
