Right here goes,

I know the tread was created a while ago but I've been thinking about this.

I have a 40mm body lift in the truck, 'if' the wheel was recessed down into the bonnet , how much clearence does the engine have nrmally when the bonnet is closed.

I'm thinking if there is around 60mm normally, and I can lowere that a further 30mm, leaving a gap, I may be able to make it so there is a clear view over the tyre.

Just a thought

Hi.

To the best of my knowledge there is little or no space between the bonnet soundproofing and the engine sondproofing on my 300TDi, as the mud on the bonnet has been rubbed off by the engine cover. Therefore, as the 200 series didn't have the engine cover I guess you might have the 10-20mm that it measures. I don't know if you have the bonnet soundproofing fitted.

Maybe this helps, a bit?

Cheers, Dan

To test the visibility why not take the bonnet off and rest a wheel on the top of the engine. This will at least show you if its worth taking any further.

Put a ball of playdow on top of the engine and shut the bonet ..

When you open it up you'll see how much gap there is ;)

ps don't use brown or you might not find it again :lol: :lol: :lol:

I don't think there's much clearance between the top of the engine and the under side of the bonnet ~ but the play-dough trick should tell you for sure.

Remember though that the bonnet is a large expanse of (relatively) thin aluminium and you're planning to mount a big, heavy wheel and tyre on it. It might well need bracing which will reduce the available clearance even more. Even if the bonnet can support the weight of the wheel and tyre it is likely to flex quite markedly when moving, especially off-road.

If you put the wheel in a recess you well have to put some form of drainage you could use some form of piping to carry away water from the engine plus the bonnet will need some strengthening to take the weight of the wheel have you got any drawings. What sort of visual clearance will you get with the wheel in this position?. There all sort of questions on this one I would love to see this done keep up the posts and add photos . Jeff

So do I :roll:

Anywho.

I will give this a try for definite, however I need to finish off making my roofrack and tree sliders first. Then do my lift and body lift, as the old truck died and I'm swapping bits over.

This means I have a spare bonnet lying around. What I'm planning on doing is cutting a hole in the bonnet the size of the wheel and refitting the bonnet, then sticking the tyre into the hole. I am planning on bracing the bonnet and adding drain holes into recess. I will also be trying to find suitable gas stuts to lift the bonnet as i don't fancy having to lift it manually.

So the truck will end up with a spare on the back, and one on the bonnet, full 'shaped' roof rack, rock and tree sliders, and full chequer plating. and hopefully ARB style front HD bumber. I get the feeling I'll also need twin front shocks and maybe even front spring spacers.

But that's the fun of Landy's isn't it, there's always something else to do!

I'll post pics when I start.

Just out of curiousity, why do you want the spare on the bonnet?
Surely it'll block your driving view and make the bonnet a pain to open due to its weight?
:-k

If he wants to do it let him. you never know it might work :-.

And they do look cool on military landys :D

They do look cool on Military Defenders, your right.
It just sounds a bit of a strange thing to be doing with a disco. :-k
Each to their own, and all that ;)

SteveGoodz · « **Reply #11 on:** March 21, 2008, 16:56:47 »

One of the reasons the current military Defender (Wolf) doesn't have the spare on the bonnet is that there wasn't enough room between the top of the engine and the underside of the bonnet to add bracing. It's not the only reason, but certainly one of them.

My thinking is because I can :twisted:

I've not seen it done, so I want to give it a go.

Just like everyone said I couldn't put a turbo engine into a volvo 240 and run high boost, oh but I can :-o :-o

SteveGoodz · « **Reply #13 on:** March 21, 2008, 21:24:56 »

Anything is possible ... if you have the time, skill, patience and (often) money to solve the problem :D

muddyjames · « **Reply #14 on:** March 22, 2008, 23:05:59 »

let me know the clearence with the play doh as I am intregued as when I jump onto the bonnet to get on the roof for vaious reasons I do wonder how far the bonnet flexes downwards to the engine.

and Im not joking! Roof rack says max 60kg on it, I am 61kg. Just avoid the sunroofs and should be fine. not had any mis haps yet!

lee celtic · « **Reply #15 on:** March 23, 2008, 15:12:27 »

I'm 100kg :oops: best steer clear of roof racks ;)

stuntman · « **Reply #16 on:** March 23, 2008, 15:27:29 »

Haha, I'm 16 and a bit stone and it held my weight without stress, although I'm not planning on making a habbit of bouncing up and down on it :twisted:

muddyjames · « **Reply #17 on:** March 23, 2008, 18:12:51 »

I do it all the time. I wash the caravan roof from the roof of the disco, put a towel on the windscreen before a frost night whilst on the bonnet, wash the disco roof, whilst on the roof, put xmas decorations up. The list is endless. The most stable step ladder I have ever used!! :D

:lol: you fat people! :lol: :lol:

i cant help thinking its the odd-way about doing a task... maybe a split windscreen next? ;) if you making a roofrack, why not make a wheel rack in it? it also means you wont be limited to a certain size wheel...

as for height.... 40mm body lift = extra 40mm between engine and bonnet, as engine is chassis mounted, and bonnet is body mounted.

remember cutting a hole = weakening of the bonnet, thus "sag" will be your next problem

good luck ;)

Haha, right I'm clearing up jobs that need to be done so I should have a go at chopping the bonnet about in 2 weeks time.

I'm happy sticking with 265/75/16 tyres to be honest as they are fairly easy to get ahold of and it's also my everyday car.
