Chip fitting for Hornby Jinty R.052

[DKB]

I have a second hand model of this loco in good condition and wish to fit DCC. I notice that there are pickups on only one side. Does this mean that fitting DCC will be problematical? I have fitted DCC to a split chassis Bachmann Loco OK.

No, it's a doddle and simpler than split chassis conversion, Triang provided everything DCC requires. (Such foresight!)

Take the connector from the pick up off the brush on the insulated spring.

Slide the insulating sleeve off the spring and cut it in half.

Put the two lengths of sleeve on the springs so that both brushes are now isolated from the spring, and thus from track supply.

Attach red to the pick up wiper, attach black to the chassis using the motor securing screw tag.

Attach orange to the brush that was formerly supplied by the pick up wiper, attach grey to the other brush.

Done. If the decoder doesn't have an insulating sleeve cover, secure the decoder so it cannot touch the mechanism.

 

The decoder needs to have near 1A continuous capabilty. For best result for least money, Zimo MX600 will do very nicely, my standard 'old mechanism' tamer. Plenty of adjustments to persuade this old dog to perform new tricks.

Thanks I'll give it a go and let you know the outcome! I'll be using a Hattons decoder as these are my default ones due to price and have been excellent so far.

Hello again, thanks for the help managed to get round to chipping my little Jinty today and by following your instructions all went fine. Slight problem with siting the chip forward of the plastic which forms the crew area but ok. Works well with the Hattons Chip I used £16 and all hard wired in easily. A little PecoLube and it runs very sweetly and better than before!! Thanks again.
