My Mysterious Talk N' Action Gordon

So I've figured out the issue with him reading tracks improperly, it has nothing to do with his actual mechanism, its the reader, Its worn, so we extended it with some superglue and he reads better, not completely so we may put a little more, but much better.
His wheelset still needs a swap tho, its done in.

So today I just opened up my Gordon, And he has a motor with instead of on the front a tan colored band/ ring around it, it's a bright orange?
Is that a light or hyper dash? or what.

Ok I looked it up, I think its a Torque Tuned Pro Tamiya Motor.

I need a thing that shows how to get to the wheels on a talk n' action Gordon so I can swap his wheel set.
Can somebody please show me what screws to remove? Thank you, I'm gonna just swap his wheels, No fiddling with wires or soldering any of that, Just a simple wheel swap.

Should Trackmaster Thomas wheels work fine for his transplant?

So I'm removing the drive unit, just trying to get the activation tab out.
Give me help and tips if you can.
Thanks.
