Plarail Oliver Replacement

So, The Plarail Oliver I got was functional, But Had a stripped Axle and he had trouble on turns, So I got a BNIB Oliver, To replace him since eventually the stripped Axle will get worse and eventually he won't be able to move at all, and this is the type of drive axel/cog with the spring so I cannot super glue it without messing it up, Oh well, But I Must have a working Oliver! This is not in any way to brag at all, Just an update on what happened.
