Flange 212 includes an inboard surface 214, an outboard surface 216 opposite inboard surface 214, a radially outward surface 218, and a radially inward surface 219 opposite radially outward surface 218. In various embodiments, with momentary reference to FIG2E, a seal 211, for example an O-ring, may be located around radially outward surface 218 and may seal a space between inboard wheel half 200 and outboard wheel half 202. Alignment pin openings 222 may extend completely through flange 212, such that alignment pin openings 222 extend from inboard surface 214 to outboard surface 216. Alignment pin opening 222 is configured to receive an inboard end 231 of alignment pin 230, with momentary reference to FIG2E. In various embodiments, alignment pin opening 222 may be configured (e.g., a diameter of alignment pin opening 222 may be selected) such that alignment pin 230 may be press fit into flange 212. In this regard, frictional force may secure alignment pin 230 to flange 212. Alignment pin openings 252 may extend completely through outboard wheel half 202, such that alignment pin openings 252 extend from inboard surface 244 to outboard surface 242. In various embodiments, alignment pin opening 252 may be configured (e.g., a diameter of alignment pin opening 252 may be selected) such that alignment pin 230 may be slip fit into outboard wheel half 202. In this regard, alignment pin 230 may be in contact with the surface defining alignment pin opening 252, but the frictional force between outboard wheel half 202 and alignment pin 230 may be reduced as compared to the frictional force between flange 212 and alignment pin 230, thereby allowing alignment pin 230 to slide in and out alignment pin opening 252. In various embodiments, outboard end 232 of alignment pin 230 may be press fit in outboard wheel half 202 and inboard end 231 may be slip fit in flange 212. In various embodiments, the end of alignment pin 230 that is to be slip fit (e.g., outboard end 232 in FIG2E) may be sloped or have a frustoconical shape.  Flange 212 includes an inboard surface 214, an outboard surface 216 opposite inboard surface 214, a radially outward surface 218, and a radially inward surface 219 opposite radially outward surface 218. In various embodiments, with momentary reference to FIG2E, a seal 211, for example an O-ring, may be located around radially outward surface 218 and may seal a space between inboard wheel half 200 and outboard wheel half 202.

In various embodiments, alignment pin opening 222 may be configured (e.g., a diameter of alignment pin opening 222 may be selected) such that alignment pin 230 may be press fit into flange 212. In this regard, frictional force may secure alignment pin 230 to flange 212. Alignment pin openings 252 may extend completely through outboard wheel half 202, such that alignment pin openings 252 extend from inboard surface 244 to outboard surface 242.

In various embodiments, outboard end 232 of alignment pin 230 may be press fit in outboard wheel half 202 and inboard end 231 may be slip fit in flange 212. In various embodiments, the end of alignment pin 230 that is to be slip fit (e.g., outboard end 232 in FIG2E) may be sloped or have a frustoconical shape.
