I use the gear set to fit my old Rail Power Products and the MDC roundhouse RS-3 and Life Like and Athearn locos. If theire is a problem in the gear, open the loco-truck and test the wheelsets if the wheels are no more fixed. Press the wheels and the drive axle gear together, control the distance with the NMRA for H0 or a caliper. The axle is 3/32", so I did drill with #43 or 2,3mm to reduce the stress in the gear, but this is not necessary.

Athearn drive axle gears.

I used these gears to replace the drive gears in the Life Like Proto 2000 GP9. The original gears were split and made a thump noise when running.Replacing the Life Like gears with the Athearn drive gears was simple and straight forward. The Proto 2000 GP9 now runs smooth and quiet like it should.
