Alan Kettlewell Posted August 17, 2020 Share Posted August 17, 2020 A little help please. I'm not familiar with 4mm loco kits (my kit building knowledge is with 7mm). Anyway I'm helping out a friend to determine the cause of a loud squeal which I've identified is coming from the gearbox, which I'd like to take off. Could anyone please identify these wheels on a 4mm loco? And what tool is required to get them off or should they just screw off? Many thanks. Cheers ...

Nick Holliday Posted August 17, 2020 Share Posted August 17, 2020 I suspect they are Romfords, or their modern equivalent, Markits. In which case one of these would help to undo the slotted nuts. It has an H end to accommodate the end of the axle. I haven't used this type of wheel myself, but I believe they can be undone without the tool, using jewellers' screwdrivers, and DJH used to provide a simple etching with which to do the deed. 1 1 Link to post Share on other sites More sharing options...
Barclay Posted August 17, 2020 Share Posted August 17, 2020 Hi they look like Romford (Now Markits) wheels. They sell a natty little 'screwdriver' that undoes them and also screws the crankpins, but you can make one by filing an old screwdriver. 1 1 Link to post Share on other sites More sharing options...

Alan Kettlewell Posted August 17, 2020 Author Share Posted August 17, 2020 Job done. I made the required tool with the aid of my trusty Dremel. Thanks again for the help - appreciated. Cheers ... Alan 1 1 Link to post Share on other sites More sharing options...
