| - | **Cam cover bushings**: \\ | + | See [[techtalk:ref:tools147#cam_bushing_reamers|Cam Bushing Reamers]] in the Sportsterpedia. \\ |
| - | The reamers for the cam cover bushings (#1, #3 and #4) need to be chamfered (chucking) reamers. \\ | + | |
| - | The ends have a short chamfer that will enter the blind bushing bore and not hit the rear of the bore before finished cutting the bushings. \\ | + | |
| - | The reamer for #2 cam can be a tapered bridge reamer on models with nosecone ignitions. \\ | + | |
| - | (the hole for #2 cam is open to atmosphere so the reamer has plenty of room to extend past the bushing) \\ | + | |
| - | Else it will also need to have a chamfered end. \\ | + | |
| - | + | ||
| - | Cam cover reamer sizes: \\ | + | |
| - | + | ||
| - | 9/16" for the pinion shaft bushing. \\ | + | |
| - | 1-1/8" for #2 cam bushing. \\ | + | |
| - | 11/16" for #1, #3 and #4 cam bushings. \\ | + | |
| - | + | ||
| - | **Case bushings**: \\ | + | |
| - | A single reamer is all that is needed for the case side bushings as all the cam bushings are the same size in the case. \\ | + | |
| - | The normal way of reaming the case bushings is to split the case and ream case bushings by using the cover bushings as a guide. \\ | + | |
| - | This will require a bridge reamer with a tapered end. \\ | + | |
| - | + | ||
| - | If reaming the case bushings from the outside of the cover bushings, you'll need a chamfered (chucking) reamer with a short chamfer. \\ | + | |
| - | The long taper will go in and touch the flywheel before the blades have a chance to cut into the reamer. \\ | + | |
| - | So reaming the case side bushings will not be possible with a bridge reamer from the outside of the cover. | + | |
| - | + | ||
| - | Case bushing reamer size: \\ | + | |
| - | + | ||
| - | 11/16" for #1 thru #4 cam bushings. \\ | + | |
