Rocker boxes receive the upper end of the hydraulic pushrods and contain the rocker arms
In order to perform mechanical work on the upper end of a Harley-Davidson Road Glide motorcycle, the rocker box cover must first be removed. Rocker boxes receive the upper end of the hydraulic pushrods and contain the rocker arms. Removal should proceed in an orderly fashion in a precise order of steps. The length of time needed to accomplish this task will depend greatly upon skill level and will generally be between 45 and 60 minutes.
1. Take out the four screws located on top of the rocker box with a hex wrench. Remove the seals to each screw.
2. Remove the upper and middle rocker covers with their associated gaskets.
3. Rotate the engine to allow both valves to close on the cylinder. Free the rocker arm bolts with an SAE socket wrench.
4. Mark each rocker arm shaft with a marking pen so that they may be re-assembled back into their same positions. Pull out these shafts by tapping them with a hammer and soft metal punch.
5. Mark each rocker arm with a marking pen. Each rocker should be noted for both location and orientation. Take out the rocker arms.
6. Remove all remaining fasteners holding the lower rocker arm cover to the cylinder head with a socket wrench. Remove the lower cover.
