430 Diffuser captive nuts broken

Nutcerts. Fix them regularly. I strongly suggest using the steel variety with the large shoulder. Proper crimping will require a special tool that has long handles much like bolt cutters.

The Rifledriver link is not opening and whatever he recommends is what I would use. I had the same problem years ago and replaced the spinning nutserts on my 360.

 

Called AVK inserts in the uk

 

You can also buy the original ones from Ricambi.

 

I assume u have ordered the installing tool for the incerts ?

 

Aluminum, and no there is not.

 

When you install these inserts, be careful not to use too much force on the handles- it is possible to tear the threads out of the small size. Just enough so the insert grips

 

As the insert thread size goes up, the outer diameter of the insert increases, no need to ream out- just use a file. No reason you could not put some Araldite on the outside before you squeeze it up. Or what ever they call 2 part epoxy in your neck of the woods

 

what is the part #, do you re call?

 

They sell every size. It wasn't easy to find but there is a page with all the fasteners for that section of the car. So if you go to let's say rear frame there is a page at the beginning with the fasteners for the rear frame. You need to know the size bolts that go there and then just pick the right nutcert. I just bought a few of every size so I had them on hand.

 

Ferrari used aluminum inserts which is part of the problem. The steel inserts are a better repair. The frame section in question usually needs a little repair and in some cases for the holes to be enlarges just slightly for proper fit of the particular inserts I use. They should be 6mm if possible. On many cars I have seen prior attempts at repair damage the frame enough that it was impossible to use 6mm inserts and I had to go up to 8mm. If a good quality repair isn't made it will snowball into a bigger job next time. If unfamiliar or ill equipped to do this have it done by someone who knows how. I have fixed far too many that have been butchered in the past.

 

If the proper part, tool and technique is used epoxy will not make it a better repair. If the proper part, tool and technique isn't used epoxy will not make it a better repair.


Ferrari does not use epoxy and the manufacturers of the inserts are not suggesting its use either.

 

I suspect the reason they used aluminum inserts instead of steel or another metal is the dissimilar metals corrosion problem. It can take years but it is going to happen. Unless there's a moderator between the steel and aluminum, one or both metals will corrode and eventually fall apart. Using similar metals, even though aluminum threads are pathetically weak, is the way for a manufacturer to go unless they want to go to extraordinary efforts to be sure there is something between the metals to stop galvanic corrosion.

If a steel insert is used, the epoxy could help mitigate corrosion.

 

Its called "zinc".

We have been using them for several decades now.

 

The inserts are plated and i have used them with salt water so they are pretty robust. Come with a shiny green finish which i think is cadmium with a passivation coat to seal the cadmium. Might have changed since i retired through as cadmium not so popular these days.

 

About the rattling of the loose cert, or something else, behind the seats of my 360 Modena. Have had one loose in the cross frame tube that forms the lower part of the engine access area and just got used to it rattling in corners. No access port so I thought about just pumping in a blob of grease in one of the bolt holes and letting the loose whatever it is get snagged by the grease. Or maybe injecting some insulation foam in a similar fashion and them driving the car around until it gets snagged in that?
Do these ideas seem to make maybe a little sense? Does not seem like it will hurt anything.

 

This might help if there is a hole somewhere to get the cable into the tube.
