I DONT CARE

[SP450andLE]

Put up a services thing on TM, but also auctions, then tell anyone who asks a Q them to go to your service listing and call/email/contact you using the details on there

would hate to start a debate about it

[Sadam_Husain]

what would you and jafa know anyway

[taz01]

I DONT CARE

im with you tom fark em all..... keep doing what you do all looks great.....

[tomsoffroad]

I was just taking the piss I believe the day you stop learning is the day you sleep with the worms

[tomsoffroad]

Well some of you might know of Sams 130 Surf I had a play with the suspension on.
This thing......





Anyways..... I used a 3 link front and rear set up. I had a yarn to my certifier before I started to see if he could see any potential problems. Go for it, I know what your works like blah blah blah. So I did.
Sams takes it for cert and fails on a few things. Inclueding 3 link front and rear!!! Bugger.

Both front and rear have an off set top link. Certifier worried about the axle tubes twisting under braking. Ok I understand where he is coming from but the front diff is trussed and the lower link mounts are below the centre of the axle tubes. I didnt think it would be a problem. Long story short, its in the shed getting a 4 link front.
The rear is only offset 130mm from the centre of diff. If the top link is in the centre of the diff its all good, but not off set. So Im doing that while Im at it.

Also........ front panhard rod needs to be lengthened (probably should've though of that first time round ) and a brace between the coilover hoops.
So hows that for a lesson on how not to make money??


The rear 3 link is now sorted. Turned into a bit of a mission to get the X member up over the tank,but I think its ruff enough









Also I have put the 4th link in the front. I'll get some pix of that tomorrow

[muddyhilux]

now that sucks ass,sorry to hear mate.ive had similar issues with certifiers saying one thing then changing their mind and of course its us that ends up out of pocket.nice work with centring the rear top link though.looks very pro

[wjw]

hey Tom,

My understanding is that is why quite a few people go to the other guy (not Wayne)

Cheers,

Bill

Im just upset cos I've aced the six certs before it
Had dealings with Don before and Wayne is much better to deal with and is a good guy to go with it. Shit happens aye, sort it and move on Wont be doing any more 3 link fronts

[LOLYF]

Wont be doing any more 3 link fronts

Sweet idea to make it a 4 link.......now you can just remove that pesky panhard rod

[tomsoffroad]

Not quite. Its a parallel 4 link so still needs the panhard

Opening a can of worms there bud.
I'm with Tom. I think most people around here would be too. The other fella is a complete TWAT!

I know....... But the other guy is consistent over time....

[kbjj]

Wayne certed my 3 link plus panard front, it's got minimal separation and an offset top link

[churchill]

Hey Tom, this problem could be modelled and finite element analysis undertaken on it to determine the twist in the housing. It would be good if you could find out from your cert guy what the allowable amount of twist in the axle housing is during braking.

I've bought a kit from the states that allows me to put a 3 link front end on my truck so I might be going through the same problem. I have FEA ability so might be able to come up with an answer, it won't be immediate as I have to do it in my limited spare time but it can be done.

[DieselBoy]

^^^^^ Take this man up on his offer, beat them at their own game!!!!!

[SamLogan]

yeah it is an interesting one. I was going to model it in Autodesk inventor and do FEA analysis on it but it becomes very difficult to do it properly. If you can be bothered to draw it up i would try but the amount of time it would take to do wouldn't be worth the effort in putting one more link in. You would need to work out the actual loads that are being subjected upon the axle etc and that would be hard to try and prove. We did manage to convince him on the some geometry issues but that was much easier to prove then that. In the long run it is probably better as it will give a much more balanced loading on the axle.

Sam

[churchill]

I suspect he's worried about the box section where the upper link is connected to. Strange due to the fact that Hilux front axles come with torque link on them from factory so you'd think the housings could withstand a good amount of torque.

[Sketchy_Racer]

I don't know what qualifications the bloke who "assessed" your work, but any one who has cut a diff housing up before would not be questioning its ability to resist warping under braking force even with an offset top link.

Do these guys make these calls from "gut feel" or is there a bit of science behind the madness. I can't imagine that they should be given the power to say yay or nay to a cert because they "Don't like how it looks"

If it were not for the fact I am flat out at work I would love to model the housing and put it through stress analysis for you in solidworks, but I put money on it that the lower links would collapse long before the housing reaches its yeild strength.

If that being the case, the only test that should matter is how it drives, if it is stable under heavy braking, there is no problem with the setup.

[tomsoffroad]

I cant really get drawn into this discussion but I do agree with the above statements.
As Sams truck is now a 4 link front I wont push it anymore, but I'm not giving up on the 3 link front, just playing the game for now

Anyways more pix.............

4th link



And new panhard mount. Shouldve done it this way 1st time round

[tomsoffroad]

Well thats that issue fixed Now to make up the 48hrs it took me

One last pix of the coilover hoop brace



Off to build a front bar for a Pajero now.....................

[tomsoffroad]

Still got a few loose ends to tie up but getting there

[ClassicCruiserSpares]

Nice work dude, be keen to see some pics of it finished then i mite chat to you about a front bar for my 80 .

Cheers man. Should have finished pix up here tomorrow night.

[taz01]

tom Ive come to the conclusion your a workaholic insomniac who somehow gets 25hr days 8 days a week the amount of stuff you do along with the quality is farken awesome ......keep it up dude nice work

Thanks
I told ya.... slaves out the back

[rokhound]

See I told ya if you kept at it you would finally design something that looked cool, and you have.

Looks real smooth fella

You'll keep
