Afternoon all. I would be very grateful for any thoughts as to the following problem I had with a Hornby J94.
It's a recent but pre used Lord Phil version. Upon receipt it was dripping in oil so I duly cleaned this off the base plate, pick ups and wheel backs. The loco was an intermittent runner and so I stripped it down cleaning everything as I went and reassembling. It looked like it was having pick up problems so I adjusted those. Still ran badly.
I was about to get grumpy and give up when I noticed one side had a lot of slop in the connecting rod and the crank pins were farther out that the other side. Tightening them gently has transformed the loco. My question is why would this work as all my other older J94s have lots of slop on both sides connecting rods. Is it just because one side was different from the other ? Apologies for long rambling question. Thanks
