| + | Reaming is the process of cutting a larger hole to a specific diameter. ((oldmetal of the XLFORUM http://xlforum.net/forums/showthread.php?t=51086)) \\ | ||
| + | The purpose is to not only make the hole the correct diameter but also to align it and square it with the part that goes into it. \\ | ||
| + | This usually means aligning it with a hole, or bearing, opposite and at the other end of a shaft. \\ | ||
| + | Reason is because the cast part can not be manufactured to hold the required alignment tolerances (and in the case of aluminum, the required abrasion resistance). \\ | ||
| + | So, the cast part is made to accept a bushing made of a harder material that can endure the force and abrasion potential that goes with it. \\ | ||
| + | The bushing is then inserted into the casting but, because of the nature of casting, it is not in exactly the right place both in horizontal position and axis angle. \\ | ||
| + | So, the bushing is made with a smaller diameter hole than is required to allow for the precise alignment by reaming. \\ | ||
| + | Line reaming is the process of using additional support features found in the engine to help provide shaft alignment. \\ | ||
