Hello there

I have a Bachmann HO SD70ACE DCC Sound Value model in NS Heritage color scheme (Illinois Terminal), on which I need to replace the front truck, as the original truck is defective and derails. As I'm not sure on how to do this, I wonder if there is anyone in the community who would be able to provide me with some guidance as to how to undertake the replacement, without me breaking the model as I don't know what I'm doing.

Specifically:
- changing the sideframes on the truck - the replacement truck has black sideframes but the original model has silver sideframes, so I need to remove the sideframes from the original truck and then fit them to the replacement truck. I've looked at how the sideframes are mounted but I can't see any easy way of removing them - I'm sure there is but I don't want to break them trying to remove them without knowing how.

- removing the body - I can see a couple of small screws on the underside, but if anyone could advise the correct way of removing the body please

- removing the front truck and then fitting the replacement front truck to the loco frame

I'd be most appreciative of any advice and guidance that the community can provide.

Many Thanks
Arthur
