New wheels for older Hornby/Triang coaches?

You maybe just about able to see the red drinks straw spacers on the outsides of the wheels. The Romford 10.5mm wheels which matched the old wheels in size were simply slid along using the old Triang axles.

I know this is an old topic but I have on old Hornby SR R 933 , it has square axels , is it possible to replace these with round axels and better wheels

Yes it is. The newer Hornby replacement 12mm disc wheels R8096 will work just fine. Don't use the Hornby 14mm coach wheels though as they are too big for your older coach.

Hi GeraldH just found this thread, would the 12mm replacements be better for the plastic wheels fitted to my old Hornby Class 101 DMU ( R157 ). Thanks in advance

R157. Isn't that a Triang or a Triang/Hornby DMU? The dummy end can have its wheels replaced if one does not mind going without a working headcode light.
See how I have changed wheels on Triang wagons. (Can't recall how the wheels are as been a long time before I had one. If they have pinpoint axles they are even easier to change. The power car needs a lot more thought).

For Triang and Triang-Hornby stock the nominal 12mm wheel fits both wagons and coaches, 14mm coach wheels raise the body, and the couplers too high. The old split axle wheel sets were about 10mm diameter but the flanges were so deep there was enough clearance to fit 14mm wheels but the greater diameter raises them too much. When Triang started fitting 12mm wheels it put the buffer height 1.5mm too high. They never changed it. It was only with the introduction of all Chinese designed and built models that they corrected it and started using 14mm wheels under coaches.
