WoF related questions - 1990 nissan safari

[XJCrawler]

Hi ORE,

I need a couple answers for the following:

Are you able to weld straight to the chassis for I.e rock sliders?

Second question for safari owners, the rear quarter cut on the guards appears that you would be cutting through part of the rear body mounts, is this legit?

Your help will be appreciated.


Cheers,

James

look at tomsoffroad he has info there i believe near the end as hes just done this

[coxsy]

yes it means a tad off the rear mounts but no one notices so why point it out
you can cut lower to
minimize the cut to the mounts

[coxsy]

and rock sliders have been covered on this forum this month search is your friend

Interesting, thought it would be different for vehicles that don't have high tensile steel chassis like today's vehicles.

I thought someone said it was ok on pre frontal impact ('93ish) vehicles?

What's the frontal impact regulations got to do with chassis welding?
Think about it and you will have answered your own question.

[tweake]

maybe i missed something here but
your not allowed to weld anything to a chassis, any welding is to be done by certified welder and i guess any add ons would need certification.
even for repairs you need to show paper work from certified welder for every wof. right pain if you loose that paper work.

Chassis structure.
Dunno, just read it somewhere...

Yea, you've missed a bit there. No need to be certified welder. No need for cert to weld to chassis (1990 safari), No need for paperwork for wof for repair job.
I'll hunt down the relevant link for you all tomorrow, this kids up past his bedtime

[taz01]

short answer for you yes you can weld to chassis .....but not allowed to drill holes unless you have welded a plate onto chassis then you may drill and tap not allowed to drill through on most 4wds

[slide]

Here's your info

http://vehicleinspection.nzta.govt.nz/virms/in-service-wof/general/vehicle-structure/structure-incl.-frontal-impact

Make sure you look at table 3-1-1 - thats the relevant bit
To sum it up- if its 4x4 (class mc) and built before 1 october 2003 you can weld on sliders etc as long as its done to acceptable standards (ie birdshite welding or sharp / protruding edges not good enough)
Note even if its got airbags, if its pre 1 october 2003 it doesn't matter.
After 2003 you'll need cert. Fun huh?

Rear cut, looks like you'll need cert for that one.. (hard to tell without having exact details of planned modification)

Hope this helps you James, And might helps others too

Thanks very much for all your help guys.

So safe to say I can weld straight to the chassis. My main concern lies with the rear quater chop, meaning I will lose some of the body mount. Is there anyone whos done this and not had to get cert, or had trouble with WoF's etc.?

Anyone got a photo of their quater chop showing where the mount got cut?

interesting.
i've failed wof before because tow bar had one side welded on. the other side was bolted on which was fine.
mates range rover has had a bit of the chassis welded, required certed welder and wof keeps failing him unless he produces the paper work for welding.

There is this bit in virm,

Note 3

The vehicle inspector may request additional relevant information from a repairer or other relevant person. The vehicle inspector should withhold the warrant of fitness if there is reason to believe that the vehicle has:

a) structural damage, or

b) inadequate structural repair(s), or

c) corrosion damage

to the extent that it could affect the vehicle’s structural strength or one of the vehicle’s safety requirements. If the owner questions the decision, the vehicle inspector should recommend the vehicle owner obtain further written assessment from a panel beater.

but the repair work would have to be fairly obvious (and poorly done dare I say it) for it to be questioned. (I underlined it to point the relevant wording for a repair job.)

But this note could also be very relevant in regard to cutting rear quarter. Ie if you could get a written assessment from a panelbeater that the job hasn't reduced structural strength, then certification would not be needed.
How I interpret it anyways..

[coxsy]

tom welds a heavy tapped plate on and bolt to that ,thats all so a aussie idea , yuo can make U type brackets to go around ya chassis two bolt throught the top to clamp them, or C type ones like Roc hound,or get u bolts made like i did for one

[tweake]

How I interpret it anyways..

i think its a case of anything thats obvious. if its all nicely painted and hidden they won't even look at it. but an obvious weld on a chassis that doesn't remotely look like original they will knock it back.
wof guy would have to put his name and responsibility to someone else welding without knowing anything about welding. hence the requirement for paper work.
also add in that bolts are graded (certified) while welding is not. so you can bolt stuff on but not weld it on.

interpretation is the key here.

[crazyclark31]

heres how i did mine. This way i only ended up cutting off the bottom 25mmish isn't so obvious. Also welded a plate to the side of the chassis part of the body mount to bolt the side of my rear bar to. No issues with a wof so far.

Can take better pics of underside if needed

[coxsy]

afront mount for a idea

rear mount if swb only lwb add one more

bit of a shock found them first up on 90 page photobucket site

[XJCrawler]

when you say paperwork to "show" a certified welder has done the work, are you talking about a legit business giving you some form of tax invoice that outlines the work they carried out?

how do you go about a mate who's a certified welder completing the work, do you get him to make a fake invoice of some kind to suit what he's done on the truck?

..and for the quarter cuts a written letter stating he believes the structural integrity of the rear quarters has not been weakened as a new #mm plate has been welded to continue the support of these body mounts?

[coxsy]

mate your over thinking the laws,
its not needed, cut the bloody thing, mind the rear light loam on the right handside add bar work under it plus paint no problem

[tweake]

good question. i shall see what mate has for his. i know he had to show it recently for his wof.

i would assume that it would have description of work, welders name and ID and be signed.

[muskie]

i always ask a certifier before i do anything welding wise, although you can ask the same question on two different days and they will contradict themselves, if in doubt get it certed... everytime i have fitted rock sliders i have welded C section to the chassis (full depth of chassis) and put three stitches either side, then bolted to that.. always taken to a cert guy and always been told no need for cert, never had trouble with wof...same with rear chop the bottom part of the mount is minor and can be made to look factory by spending a little time tidying, there is a water drain hole anyway...having said that i always cert once my truck is done to avoid any troubles, i think having the paperwork covers any hassle, although its a ripoff i feel safer legally.

[XJCrawler]

well rears are now cut and welded some 2mm plate under there, looks really tidy actually. got some underseal and slapped that through. couple of offroad trips should make it look old and semi-factory.

roughly 20-25mm come off the body mount not too noticeable with the plate cut and welded to suit and yeah the underseal just hides it all. will post some pics in the next couple of days if anyone's interested in doing this chop on their safari.

also i got in touch with Wayne Martin via his daughter, and he's told her that the cut would require cert, but won't be an issue if it's cut and welded properly (can't see how you would stuff that up anyway).

next thing on the list is getting the rear bumper and rock sliders done. should have these finished in a week or two. got some good ideas what to do now, thanks for all your input guys.

one down fall while i was doing some other bits and pieces on the truck i found huge amounts of rust (right through) on the rain channel, this happened to about 5-6 sections. not pretty at all. come up with the idea of chopping the sections out and getting mate to fabricate some new pieces to weld in. not having much luck with the roof in terms of rust, can't have had much of a garage life before i got my hands on it.

Photos if anyone's interested

have a look here second pic shows my roof/rain channel repairs on my old saf, you can do it judging from the rear chop youve done, just take the roof lining down.. i have other pics if you need more.

hats off to you, that's some good repair work.

i spent today with the grinder cutting some of the rust out, it's like it's rusted from the inside out, the second layer (internal) is rusted near the a-pillar driver side quite significantly, goes toward the back of the truck. at the moment i've cut a majority of the rain channel out, cleared out most of the surface rust i could get too and flooded the roof inside with fish oil and primed. temporary sealed the holes with bog until i get a work vehicle to take it off the road and remove every last bit of rust. but its looking like a donor vehicle would be worth the money (if there's a good one been garaged most of its life - a new roof could be necessary).

[crazyclark31]

there seem to be plenty being wreaked at the mo. Surely you'd be able to pic one up? know a couple of people that have replaced the whole roof due to rust.
