I thought I would answer the question. Will a TCR Jam Car rear gear work as a replacement in a US-1 chassis?
Answer is Yes and No.
No, The gear is not a direct replacement.
Yes, The gear can be modified to work.
Here's what I did.
Removed the weight (fifth wheel), rear guide pin and rear tires.
Placed a coarse finger nail emery board between the pickup shoes.
Placed the chassis on the track. Started in the forward position. This took some coaxing to get the motor to turn.
Let the chassis run for about a minute, stopping to check the axle for the desired amount on play in the rear gear. This took several attempts.
Lubed up the new gear after I was satisfied with the amount of play in the gear . Reassembled and good to go.
I'm pleased with the results. This is good for a runner.
It beats looking for a replacement chassis.
Cheap jam car gears are everywhere on ebay.
IMO 3d printed gears do not last.
