| - | ===== Modified Cover for Reaming ===== | + | **Homemade bushing remover**: \\ |
| + | The puller is made from 1" ID black pipe and 1/2"-13 threaded rod. You tap the flex head-puller head through the cam bearing. \\ | ||
| + | The little nub puller with a collar that you knock into the bearing is made from 3/4" rod. Then screw the rod into the head to tighten the jaws. \\ | ||
| + | Then place the collar over the rod and nut to start the pulling. \\ | ||
| - | | Modified cam covers for reaming ((left photo by decman of the XLFORUM http://xlforum.net/forums/showthread.php?postid=5016753)) ((right photo by Hippysmack)) || | + | 4 grooves were cut into the end for flex / compression to push through the bearing. \\ |

| + | The threaded rod causes outward pressure on the jaws of the head when pulled. \\ | ||

| - | ===== Reamers ===== | + | |
| - | **Cam cover bushings**: \\ | + | |
| - | 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: \\ | + | ====== Bushing Installation ====== |
| + | These are typically knocked in with a commercially available long rod and a hammer. \\ | ||
| + | Below are a couple homemade tools for installing the bushings. A knocking rod and a compression plate. \\ | ||
| - | 9/16" for the pinion shaft bushing. \\ | + | The knocker rod is made from 1" aluminum bar stock with a .030" shoulder to recess into the bearing, .030" into the case. ((fergerburger of the XLFORUM http://xlforum.net/forums/showthread.php?t=1349714)) \\ |
| - | 1-1/8" for #2 cam bushing. \\ | + | |
| - | 11/16" for #1, #3 and #4 cam bushings. \\ | + | |
| - | **Case bushings**: \\ | + | The compression plate is made from a scrap steel plate. The bolts screw in to push the bushings in place. See the [[techtalk:ref:tools107#reverse_engineered_cam_bushing_installer|build pics]] below by Hippysmack. \\ |
| - | 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. \\ | + | {{:techtalk:ref:tools:homemade_cam_bushing_tools_3_by_fergerburger.jpg?direct&300|}} ((photo by fergerburger of the XLFORUM http://xlforum.net/forums/showthread.php?t=1349714)) {{techtalk:ref:tools:cam_bushing_installer_41_by_hippysmack.jpg?direct&300|}} ((photo by Hippysmack)) {{techtalk:ref:tools:cam_bushing_installer_39_by_hippysmack.jpg?direct&300|}} ((photo by Hippysmack)) |
| - | The long taper will go in and touch the flywheel before the blades have a chance to cut into the reamer. \\ | + | ===== Modified Cover for Reaming ===== |
| - | So reaming the case side bushings will not be possible with a bridge reamer from the outside of the cover. | + | |
