Newly developed replacement for the original contacts (K320/A) which may be unreliable during operation.

Replacement is very simple (see video). When replacing the contacts for the front wheelset, the plastic pin on which the contact is attached may be damaged / broken. In this case, a plastic rod is included for making a new pin (see video).

The contact must not bend and touch the metal frame - check.

Included with the contact set is a plastic rod for making a pin on the locomotive frame if the original ones get damaged.

Recommended procedure for installing a new KaModel contact
If the contacts come with a plastic rod for attaching the contact, we always recommend using the plastic pin manufacturing method to attach the contact. This is a more gentle procedure with the possibility of additional repairs. Rivets use only in recommended applications where a very tight fit is required. Contact damage often occurs when the rivet is removed again (if a repair is needed). The rivet can be drilled or ground off.

The procedure for attaching the contact using a plastic rod.
1. Cut the plastic "pins" holding the contact with a sharp cutter.
2. Use the original contact as a drilling template and carefully drill all holes with the recommended drill. It is advisable to use the original drilling contact to avoid damaging the new contact when drilling.
3. Stick in the supplied plastic stick with instant glue and cut the other side flat. On the contact side, trim the stick with an overlap of about 1mm to create a new pin.
4. Insert the contact and melt the pin with solder at about 230ºC to create a wider head holding the contact.
5. Re-drill the pre-drilled hole through the already fitted contact to make another pin and repeat the process.
6. If the procedure is not successful the first time, this "operation" can be repeated several times.
7. Watch the sample video with contact replacement.
