Locos failing left right and centre.
First it was my Lima Class 33 that needed a motor transplant (motor obtained from www.strathpefferjunction.com). Then it was my Hornby Class 700 that needed a motor replacement (obtained from Peters Spares; discovered later I could disassemble the original motor and repair it.). Now, My Hornby Bulleid Merchant Navy Class exhibited gear slipping.
On the left is the gear assembly comprising a large (white) gear and a replacement for the one in question. This assembly has the number X8849 and whilst spares are listed by several suppliers all had no stock available last week!
What to do?
The faulty gear has 21 teeth and is about 11.5 mm in diameter. I searched eBay for 'hornby 21 teeth gear' and one popped up. It was also identified as 11.5mm diameter but, listed for Hornby Britannia. Taking a hunch that the manufacturer would have applied economies of scale and assigned it to other locomotives I bought it and to my delight found it is a direct replacement for the Merchant Navy gear :-)
