Replacing pancake motor or truck

[ThomasStrain]

I have my sons HO pancake motor locomotive.
The motor is unrepairable. Armature is open.
Does anyone have an old pancake motor?
Is there an updated truck I could get to replace the old one?
Thanks

Do you believe just an armature would solve the problem?

I have armatures.

A new locomotive is always a better deal when a pancake motor is involved.
