Model Railway Forum

I have posted this on other forums in the hope of finding someone who has solved this problem

I have a Hornby Castle "Wellington R3105. A very recent model but a non runner. The crankpin on the leading drivers foul the crosshead on a R2 curve and jam. The result is the slide bars disconnect from the cylinders and chaos reigns





It fouls by a fraction of a millimetre but it is enough to jam the motion. With this model Castle the slide bars are just pressed into the cylinder and can come loose easily. I am tempted to glue them in but I dont think that will solve the problem. It is not a good design. I cant send it back as I have added a chip, sound and a stay alive (Youchoos) and had to modify the tender to get it in

Question- Can I put spacer washers between the driving wheel and the frame to lessen the lateral travel of the driving wheel. How much would that effect its ability to handle a R2 curve
(This would be a major fix to remove a wheel from the axle and re-stablish quartering. Not sure it is worth it!

Any one had experience with this castle

Rather than ‘treating the symptom instead of the cause’, I would suggest trying to get a replacement for the faulty parts. Maybe Peter’s Spares or Hornby themselves. Failing that, carefully filing down the length of the crankpin would be better than budging the wheel movement.

Should the pin be that long. Is it seated correctly?

Hi

Looking at the photo compared to the other side is the pin causing the issue the right way round, do the two sides match.

If it does match then one way of sorting the problem would be to file the offending pin down so it does not catch
