I found a hole!!!! Ali corrosion

Thought id get cracking on the soundproofing today, nice and easy i said. How wrong i was...

Found a hole, many holes actually, ali corrosion, how do I fix this? Cut it out and rivet a panel on top?

For me , it would depend where it is to how it gets fixed.

Rivets or bolts.

Cheers

That's what I did bud.

When I changed the chassis there was hardly any good Ali at the front of the tub, where the steel meets the Ali, I cut out all the crud, shaped some new Ali, coated the side where it was in contact with the steel with some thick underseal stuff and riveted it back. Its actually pretty easy....good luck

So it really is a simple case of cut it out, rivet a new sheet on top with sealant. phew!

Same on the other side!

Uuuurggghhh,

That looks nasty, where exactly is that @bankz5152


Cheers

@neilly Yep! rear seat box

Is that the same vehicle as in your avitar?

Nope, this is my 110, thats my old 90 (currently for sale)

Old picture now but I had to fold and cut/shape new panels on my sw tub , it started with small bits of corrosion in the 2nd row area but developed into needing everything replacing .
Not shown in the pic but new rear floor, wheel box sides and rear panels (the panels with the rear lights, number plate etc on them). I'm a bit anal with rot though, it's got to go and not come back ever! Wherever possible.

My pic shows the same panel doesn't it?

Yes is does! Ive checked the area veryc closely, there is only corrosion on those two areas.

Ive already managed to seal up the smaller holes with Lumiweld (not half bad! pics to come). Then picking up some Ali today, silicone, rivet in place.

I don't know because I only know the make up of the 90, but is that a structural connection for the rear body to the chassis? Looks like a main bolt down point looking at the picture showing the bolt holes in the steel section that's visible through the corrosion hole. Just thinking out loud.

It is, four brackets iirc bolt to a removable cross member which in turn bolt to the chassis. Corrosion in that cross member is an MOT fail.
The repair is sort of ok though imho in the great scheme of things but in these elf n safety times ....
That whole panel is spot welded on to the rear floor and has triangular end caps which also spot weld on.
What I did was drill out the welds to release the panel, remove the end caps and take it to a place that does folding and they knocked up the two folds for that panel in the 3 mm chequered plate that I supplied. The end caps, if good, can be reused . I blind steel rivited it back on which, arguably, is not as strong as the spot welds.
With Bankys repair I would be tempted to use large thick spreader plates that extend much further than the corrosion ..

Just had a quick look at the YRM repair panels for a 110. YRM LINKY

The steel seat supports are intact and un damaged with zero corrosion. They had spacers behind them which are also undamaged.

Cheers for the link! that looks good, ill check it all out now.

Few repair pics -






The otherside isnt going quite as well, the holes are larger so using an ali plate riveted in behind.

Had what I think is a good idea! Once I paint the ali sheet and its dry i thought i could cover both the front and back with some fatmat, should prevent any more corrosion from happening!
