The wheel hubs are sized for #8 screws. Did you drill them out before you tapped them for the #10's? If not, you could have stressed the plastic when you used the tapping tool to create your threads. |

Re: pic: Wheel problem.
This is the link to the AndyMark Cad file, which clearly shows the sprocket mounting holes to be 3/16" (.1895).
http://lib.store.yahoo.net/lib/yhst-...lick-Wheel.pdf The tap size for a 10-32 is about 5/32" (75% thread clearance), clearly smaller than the existing hole in the wheel. It would seen to be far better to open the hole slightly for the #10 bolts to go through, and jamb nut the bolt/sprocket /wheel assembly together. #8 bolts would be too sloppy in the existing holes (maj. diam. of .164"). ![]() |

Checked the wheel mounting hole size last night on a wheel, and they are definitely NOT sized with a 10-32 or 10-24 tap hole. An 8-32 clearance hole is about right, but a little more sloppy than I would normally like. If you keep your sprocket and spacers centered on the wheel hub, the 8-32 bolts should work fine, and you will eliminate sprocket runout. Sorry for my previous post, but I even checked with A/M and was assured the CAD drawing was correct a 3/16". |
