This is a quick guide to improve the appearance of the couplings on the Roco HF110 and make them self centralise.

How to make the couplings look better:
Remove the chunky Bemo type couplings that are fitted as standard. These are a simple clip fit and just pull out.
Next take the alternative couplings supplied in the box with the loco and cut the front of the head off.
Clip this coupling in place and glue the head of a Greenwich coupling at the correct height using super glue. (I use a Roco four wheel wagon as a height guide for all my 009/H0e locos and stock.)
Unclip the coupling again and paint any parts where the plating has come off the Greenwich coupling and any shinny glue that is showing.
When the paint is dry add the coupling outriggers supplied with the loco and clip the coupling back on.
With the tender locos the rear coupling on the tender can be just glued centrally as the overhang is very short so it causes no problems on curves.
This is what the finished item looks like on the tender:

Self Centralising
This works with the original couplings and with the modified couplings described above.
Place the loco upside down in a foam cradle. (Or similar.)
Undo the two philips screws that hold the axle retaining plate to the chassis and carefully unclip it from both sides at the rear.
Do not let the axles fall out as they can be a bit difficult to get back in again.
With the retaining plate removed you can see the front coupling pocket. Cut a section out of Royal Mail elastic band so that it fits behind the coupling C clip.
It should look like this:
