    I've had one of these awaiting a service ever since I bought it 2nd hand. Finally got round to it yesterday. After servicing, without the body on, it ran like a sewing machine. Put the body on and it sounded like a bag of graunching nuts.
    Concluded the body was acting as an echo chamber so stuck blu tack into the voids (obvously the body, not the chassis!).
    It was ok for about minute, then the graunching started again. Fiddled with it again, but still graunching, yet no noise without body.
    The body is clipped on ' no securing screws.
    Any suggestions?

    Strange one that. I am sure someone will have the answer. It'll be interesting to hear how it is resolved.

    I think I'd be looking to see if there were any signs of wheels rubbing on the underside of the splashers first Dave. If nothing noticeable, could you run the loco in an upside down position (possibly using a makeshift 'cradle' to hold it), touching wires onto the wheels for the power supply, and see if there is anything more visible (or audible!) like that. Failing that, as you've mentioned that the body only clips on, is that the cause, vibration of the body itself due to not being securely fixed to the chassis?

    I did think the clipping was a possibility. I tried a blob of blu tack underneath the footplate - maybe its not sticky enough and came loose, so I'll try tacky black on Sunday evening, and get some on the front as well - after trying the inverted idea you suggested.
    Cheers. Dave C.

    OK - tried the upside test - no joy. Tried tacky black instead of blu tack between chassis and body, and got soem blu tack stuck near the front clips, and more on the inside of the water tanks. No joy. Then discovered the graunching was now occuring with the body off! Tried loosening / tightening the motor on its mount - no luck. Applied more lubrication to the armature shaft bearings - no joy. Applied a bit more - bingo. :headbanger: The bearing between the armature and the worm took most of it - now on older Hornby chassis there are felt pads which I've found need to be well soaked in oil when they have dried out - no sign of felt pads on this, but there is a sort of brass housing, and I'm wondering if its stuffed with felt?

    Anyway, another bonus - there is now so much blu tack inside the body the Jinty can now just about make my 1 in 40 incline - just got to sort the poor running axles out on the 2 suburban coaches its pulling and that should be another problem sorted.:)
