michl080 Posted January 28, 2018 Share Posted January 28, 2018 (edited) greetings, I am building a MMP Class 08 kit and am running into a problem with the Slaters wheels. If I try to push the wheels onto the axles, they get stuck quite quickly. I don't want to push them too hard, because I am afraid that I wouldn't be able to remove them again. I would need to push them some 4mm on either side to the shoulders of the axle. This seems very odd. If I try to measure the diameters, The conical hole in the wheels is at least 0.1mm too small. A force fit with 0.1mm interference seems too much. Any idea? Should I try to push them further using vice?

michl080 Posted February 3, 2018 Author Share Posted February 3, 2018 Hi, no reply so far, so I will answer my own question: In between, I contacted Slaters and asked how to proceed. I got a nice reply from David White with a good description how to push the wheels onto the axles. I followed his advice and managed to get the wheel successfully onto the axle. However, as you can see, it requires a massive force that is applied perfectly in line with the axle to avoid bending the axle or resulting in a wobbling wheel. The trick is to use a piece of matching tube to push only the bush, but not the plastic wheel. I recommend to use a tube cutter for the pushing tube. Cutting the tube with a saw will probably result in a cut that is not exactly perpendicular and will push the wheel unevenly. I couldn't apply enough force with the handle of the vice, so I had to use pipe wrench for the last Millimeter. It is definitely necessary to apply a good grease to lower the friction. Funny enough, I could get the wheel off quite easily after pushing it on and it could be reassembled a lot easier, so I assume that the bush has been slightly extended at the first assembly. Maybe somebody will have the same problem and stumble over this description. Michael 1 Link to post Share on other sites More sharing options...
Woody100 Posted February 3, 2018 Share Posted February 3, 2018 Michael, When I built my MMP 08 the axles were supplied by MMP. Although it was around 5 years ago now, I do remember Slater's axles were supplied with the wheels but slightly different one were needed. Hope this helps?
