How to Pull Rocker Studs
The rocker arm gets its name from the action of the part. The rocker arm is attached to a stud that is pressed into the head, and rocks between the push rod and the valves. When the push rod pushes one end of the rocker arm, the other end of the rocker arm opens the valve. Occasionally, rocker studs wear or become damaged, and need replacement. Normally, replacing rocker studs is really a job for a machine shop, but aggressive do-it-yourselfers can save some money by pulling the rocker studs themselves.
Instructions
- 1
Remove the valve cover. Remove the rocker arm nut from the stud by turning it counterclockwise with a wrench. Lift the rocker arm off the rocker stud.
2Slide a stack of flat washers onto the rocker stud. Leave enough space at the top of the stud to fully engage the threads of the nut.
3Thread the nut back onto the shaft. Tighten the nut by turning it clockwise with the wrench. As the nut threads move down the rocker stud, the rocker stud will gradually pull out of the cylinder head.
