PCB Cover Issue

Has anyone come across this problem: The replacement 3D printed cover has warped with heat. What temperature should this part of the loco withstand? What material is used? I have used these replacements on other locos with no problem, so what has changed here? Presumably they are there to insulate th

Hi Chris, How old is the cover?? The earlier printed covers were printed in Pet-g and we have changed to ABS as it is more stable. Nothing, even hornby originals wil resist the higher temps caused due to an electrical issue. When you make your next parts order, I will include a replacement for you.

Front End Maintenance

Recently I decided to do some in depth maintenance on my locos, and it can be frightening to find things that need fixing. On removing the rotary valve cover on my Silver Link, which was actually running ok, I discovered the rotary valve had a deep concentric groove worn in it from the compression spring, the wear pad, what was left of it, served no purpose at all. Needless to say, a new valve, pad and gasket was fitted.

Elsewhere, other inspections found the wires to the wiper board were only held in place by the 'Grace of God': Age and the constant heating and cooling had takin it's toll, the wires were only attached by a couple of strands.

In general taking time to check all the screws for their tightness is also worthwhile.

Hello John, Recently I had to renew the wires from the wiper board so I drew a rough sketch of where they have to go. The red wiper wire goes to the top left of the board and the black one goes to the bottom left. Similarly red motor wire to the top right and the black to the bottom right. Happy soldering! Chris

Rolling Road

Hi all

It’s been a long time but finally got to running my Silver Link on my home layout!!

Want to test run on my Hornby Rolling Road first but cannot remember what our sadly missed Maurice told me best to connect power to the rear of tender as over static use could create flat spots on the tender wheels.

Can someone send me a diagram or picture as to how this connection is made, I just cannot remember!! It will just save me messing about and maybe getting it wrong.

I’ve only ever run my Silver Link on the club test track.

I know it’s not proto typical but recently bought the beautiful rack of articulated coronation coaches c/w beaver tail unit.
