I have an older Williams dash 9 I bought a few years at a train show.  It has dual motors.  One of the axles... The helical gear is spinning freely thus the wheels on that truck are not getting power.  I'm trying to remove the wheels on the axle to get to the gear but not having any luck.  They are stuck on solid.  Any advice for removing wheels on a williams diesel truck?   I thought about just buying the whole truck assembly but they are out of stock with williams.

Thank you!   Fortunately I was able to get it going on my own.   For anyone searching in the future who may be interested.... I was never able to get the wheels off, however I decided that I could rough up the knurling on the axle shaft by sliding the lose helical gear to the side.  I then took a punch and disturbed the knurling under the gear with a few good blows.  The axle showed no signs of bending, and it took a fair bit of strength to make the small dents.   I was added a few drops of ca gel and pressed the gear back into center. After that dried, I used a flathead jewelers screwdriver to apply some jb weld where the gear meets the axle and let it dry overnight.  I ran it for about 10 min this morning at a good speed and it's working well.

Well done. As an aside, another and possibly better fixative for the loose helical is Loctite.
