- It is necessary to drill oil holes in bushing to coincide with oil passage in rocker. Holes may be drilled before or after installing bushing in rocker.
- If holes are drilled after installation, remove adjuster screw and use a 0.093" (2.4 mm) drill to drill oil passage through bushing. Plug rocker end after drilling with a rivet, and weld rivet into position. Oil hole in top of rocker barrel must also be drilled with a 0.0785" (2 mm) drill. After drilling, burnish ream bushing to 0.6255 - 0.6260"" (15.8-15.9 mm).
