Mondial Qv Exhaust bolts dumb questions

Hi, when I changed my back box, I just used new bolts I obtained from the local factors, nothing special.
Similarly, with the O rings I went to to local Exhaust Place and asked them to match it if possible. The one I used in the end looked like a steel wool doughnut, I put sealer paste on it and it crushed (as designed) into place.
Perfect job.
I cannot answer your third question, I carefully blasted mine and painted them, I have not had any problems so far.

Good Luck

 

Pete,

When I changed the exhaust on my old Mondial QV, the hanger springs looked pretty nasty also. I just cleaned them up and painted them, like Phil said, with rust-proof paint. They are up high and no one sees them anyway. I just did it to protect them from future corrosion. As long as the mountings are sound, no reason to replace them. But if you are dying to replace them, you should be able to find the part numbers on the Ferrari UK website.

I got my "olives" from T. Rutland here in the US. But I'm sure you can get them from Ferrari UK more easily over there. It's a stock item, not expensive. And you don't need grade 8 bolts. Stainless bolts, properly sized, should be fine.

I have the same problem, OEM Ferrari springs are $18.00 USD ea, so I’m having 100 SS springs made from .160 wire, all but 20 will be for sale. Should have them in a week. Probably be in the $4.00 USD range.

What Philip said for the first two questions and yes there all the same for question 3.........I just strip em down and have them bead blasted, normaly brings them up like new

 

I think this is where I disagree with my friends on the forum, I just run the car up on ramps. Its easy and quick and safe. Only good if you don't want to take the wheels off.

 

In the centre on the engine support crossmember........not the crossmember with the anti roll bar

Phil's sugestion of ramps is equally as practical if you don't have a lift

 

Pete,

Let me tell you, those springs are not bad. Mine were worse, and with a little bead blasting, they cleaned right up. IMHO, don't waste your money. Clean them up a bit and spray them with Rustoleum (or whatever anti-rust stuff you get over there) and forget about them.

My Mondial was a Euro spec car, so no cats. I did not remove the short pipes. I only replaced the exhaust/muffler. The old olive can either be knocked off with a chisel and hammer, or if it's too stubborn, use a grinder or Dremel type tool. Just be careful, go slow, and don't bugger up the pipe. (Like the way I slipped in that nice British terminology??).

Have fun!

 

Sorry for the confusion, I was refering to the springs which hold the exhaust flanges togeather, Three used per flange. The springs in the picture is the hanger bracket. When I restored mine, I removed them from the car, bead blasted them and had them yellow zinc coated. They look like new except for a small amount of pitting. If you take yours to a plating shop tell them to bake the springs in an oven at 350 F for 4 hours or the zinc coating will just flake off.

Take them off, pull them apart, paint / plate them and put the back on, your building a race car not a conkers contender.........if your really worried about how it all looks underneath you may want to invest in a tub of TFR (truck wash) and clean all the dirt off what I'm really trying to say is even with the noblest of intentions I'm sure your money's better spent on bits that will make it go faster rather than prettier

 

The zinc parts is a regular clevis, purchased at the local hardware store. It is a standard 3/8-16 thread so I drilled and tapped it to mm size. This was only done to get me by during the exhaust system construction. I'm having a custom 304 exhaust made and the exhaust needs to be removed several times during its construction, I wanted something cheep. Anyways, I'll have the clevis made from 304 to match the rest of the exhaust system when it's complete.

 

Just a thought guys, but you might want to check a marine supply specialist. Stainless steel turnbuckles and clevis pins are used in a lot of applications, especially by sail boat racers.

Quantity always helps in the build price, but Bill308 suggestion may be the best option and least expensive if you can live with something off the shelf. I'll have them reproduced like original except in SS. That way they will look correct an never rust. If you want, I will check on the price, just let me know.

Not sure about the hangers but Peter gave me a great idea for the bolts. He suggested using 288 exhaust bolts. Don't know about the later cars but on my '78 the existing stuff was studs, springs, washers, and nuts. It would have been very expensive to buy all new 308 hardware but was only 150 GBP for all new 288 bolts springs, washers and nuts. I wasn't too worried about the hangers since you really can't see any of it on a US spec car and they seem to be in decent shape. I wanted to replace the hardware though because it was not in the best shape.
