1954 235 rocker arm push nuts.

[img]https://www.stovebolt.com/ubbthread...ame/16243694666743798942508483389441.jpg[/img]On top of the rocker arm lock nuts there are also a spring steel push nuts. That I assume helps keep the lock nuts from loosing up. I took off the valve cover to adjust the rockers and noticed that three of those push nuts had fallen off. Do I need these to be there? And if so, where to buy new ones?

Thanks in advance.
Elmo.

Can’t say I have ever seen spring nuts on top of the rocker adjustment nuts. My ‘59 235 does not have them. Maybe thats why their coming off.

Can you post a picture of the rocker with the spring nuts installed?

Those are called Pal nuts, are used on aircraft, external places, not on internal locations, among other places. Not required on rockers, small enough to be sucked into dangerous places.

They're called "Pal-nuts", and they aren't original equipment. Pitch them into the nearest circular file and don't bother to reinstall them. They're used on 235 connecting rods in some applications, and they're also worthless there, although Chey did use them as OEM for some silly reason.

Wow you want to get rid of them. If they came off they could make an awful mess.

Ditto to ather responses. Be gone with em. Extra unnecessary parts gettin flung around in there is not an ideal situation.

I will remove them tonight and discard. They were there when I bought the truck.

I wonder if the pal nuts were deemed necessary to keep the connecting rod dippers in place, then continued using them on the later 235s just because.

Probably not- - - -the PAL nuts wouldn't have enough strength to retain the dippers- - - -they're always installed between the rod nut and the cap. The force of the dipper hitting the stream of oil several times a second would rip the sheet metal nuts off.

Isn't it amazing what we sometimes find both in and out of old engines. I believe the reason is due to some folks believing that simplicity of an engine meant simple applications. Maybe Jerry can go on the Greasy Spoon and elaborate, he has to have some interesting stories. Ed
