you have to remove the pressed in studs ,and tap the hole with the proper thread size for the threaded stud. this may require drilling the heads with the proper size drill, for the tap size you need. you must make sure that the new threaded studs are bigger than the pressed in ones, or you won't be able to thread the stud holes.
Some do some do not. Look at the stud, if it has a nut built into the stud bottom, then it is a screw-in
drill a small hole through the stud boss,stud and tap a pin through both boss,stud. This is called stud pinning, you can get a kit from napa for about 20.00 bucks comes with studs,drill bit.
with a hammer. u just smack it. they are pressed fit
To remove a pressed-in stud, you usually stack up a few washers and crank the stud out with an impact wrench on the nut. If the threads are completely stripped all the way down, you may have to take the head to a machine shop and have the stud drilled out and tapped for a screw-in stud.
rocker arm stud is pulling out. how can i get it back in
stud has all its length threaded and it is used with two nuts, but the bolt has one end closed and the other end is threaded ,it is used with a single nut.
Worn out rocker nut, stud pulling out, or bad cam.
Your best bet is to buy the manual. There are multiple ways of adjusting rockers and it depends on the vehicle. Your loose rocker arm may also be an indication of a bent push rod, bent valve, or worn out cam. there are 2 types of rocker arm studs pressed in and threaded in. if it is pressed i suggest buying the same size threaded stud, tapping the hole and using 2 stacked nuts screw it into the hole in the head. if its threaded just remove the old one and thread in the new one, be sure to check torque value for this application answer if a rocker arm is broken, u need to remove rocker cover the rocker arms are all on one tube bolted to the head remove the nuts that secure this tube slide as many rocker arms as need to get to broken rocker arm, off the tube replace with new rocker arm replace others that u needed to remove. sit tube with rocker arms back in place making sure that u align all rocker arms to the proper place tighten securing nuts to proper torque over tightening will break the studs then adjust rockers to specs if engine has hydraulic lifters you will not have to adjust replace rocker covers using new gaskets if the rocker ram is loose, adjust to specs if engine has hydraulic ligters, torque to specs job is done
Remove a rocker cover and measure one.
No, It does not change the ratio of the rocker arm. ( lift or duraration ) They are designed to keep from cutting into the rocker arm stud if you have a 500 lift or more camshaft that's it.
You have to much lift on the camshaft lobe, They make a long slot rocker arm that looks like a stock rocker arm but it will not cut into the stud. The slot is where the rocker arm fits over the stud. If you are not haveing coil bind problems with the valve springs are broken springs then you can keep the cam that's in it and just use the long slot rocker arms are roller rockers to fix you problem.
Take them to a machine shop and have the wheel lug studs pressed out. Or using a lug nut threaded onto the very end of the lug stud (to prevent stud damage) place a socket on lugnut and hammer the stud out. After all studs are removed the rotor and the hub will seperate.
