| + | === Lapping Tool for Rocker Arm Bushings === | ||
| + | |||
| + | A lapping tool can be made from a 1/2" wooden dowel and a small piece of sandpaper. ((photos by Hippysmack)) \\ | ||
| + | Make the dowel long enough to run the full length of the rocker arm plus enough to get a hand on to turn it (12" or so). \\ | ||
| + | Use a hacksaw blade cut a slot down the middle of one end to hold the sandpaper. \\ | ||
| + | Make the slot longer than the bushing so you can be sure to have contact on the full length of the bushing. \\ | ||

| + | |||
| + | Initially cut a piece of sandpaper to go one full revolution around the dowel. ((photos by Hippysmack)) \\ | ||
| + | Too many wraps will not slide into the bushing as it will then be too thick. \\ | ||
| + | You just need to turn or lap the bushing slowly and evenly. \\ | ||
| + | Grit of sandpaper will be determined by the condition of the bore and clearance desired. \\ | ||
| + | Insert the bare end of the dowel into the bushing to lap and exit the dowel out the non lapped bushing. \\ | ||
| + | This will allow you to basically line lap the intended bushing to help keep center between the two. \\ | ||
