Finished it last night but had a problem with the camera SD card so only managed to rescue a few pics, but enough to get a good idea of what's involved ..
Used this stuff to seal and glue everything together ... used it on my windscreen surround and it's made that waterproof, so should be good for a snorkel. Part No STC 50551 (didn't realise the pic didn't get the No in fully)
Holes in airbox bottom ...
Sealed with the sealant and these plugs ...
Fitting the reducer from pipe to airbox
airbox all fitted back ..
Top put on loosely for now. I will seal and adhesive it later.
And the whole finished thing ... needs a bit of a clean, whatever I touch i get it mucky, doesn't matter how careful I am ..
So, a few observations ..
I've not sealed the wing/tube plastic 'grommet' to the body yet, going to give it a few days for all the bits to bed in and settle, and I want to edge the wing hole first.
The self-tapping screws for the A-post bracket are crap, and I appear to have run out of M6 rivnuts, so ordered some to do a 'proper job'. Similarly the Allen bolts supplied are soft (self-tappers and allen bolts are stainless so obviously soft) so they'll be replaced with decent socket screws as soon as.
The flexible tube from snorkel pipe to airbox is the main bit .. it's the right diameter to fit inside the standard airbox inlet hole, but can't be held in reliably without the reducer .. which could be easily made up, IMHO and the length is just enough (1.5m) with just a tad extra, so it isn't pulled or pinched too tightly. A 1m length simply wouldn't do.
It's not necessary to take the wing off, but the wheel well plastic shrouds are a b'stard to remove and refit properly! It's hard labour, and very fiddly, pushing stuff past other stuff, but it can be done in about ten to fifteen minutes! If you have the strength of Garth, the thin arms of Mr Bean, and the dexterity of a chimp then it might be easier ..
The wing hole template as supplied seems to make the hole too big at first, but there's a fair amount of manouvreing to do and it does make sense for clearance and to keep from bending the wing. I'm going to use some rubber tubing, split lengthways, to 'edge' the hole, the stainless snorkel tube almost catches and I suspect might make some vibration noise, so this might stop it.
Altogether it all seems to fit nice and closely, with the snorkel top below the roofline so won't intrude on the scenery/foliage too much I hope. Looks good, and seems strong enough to withstand knocks, once the mounting bracket bolts etc are sorted! I think I'm going to make an extra bracket to bolt through the top and to the roog gutter, might stop tea-leaves who fancy nicking the top from actually doing so successsfully!!
Certainly, IMHO, worth the money. I got the unfinished thing for £139 from Southdown, via ebay .. for something like this that's out there getting hit by the brush and trees I wouldn't bother with any finishes or painting it (though black stoved might be good!!) as it's just gonna get scratched anyway .. this way you only need a bit of wire wool and it's cleaned up again!
