For Questions Regarding WOFs/CERTs/NUMBER PLATEs

Recommended Posts

That is kinda a dumb rule really; my bmw had a wild steering wheel shake at 120 on the motorway to the point where I had to drive slower than the traffic, fitted hub centric rings to the front wheels and now it'll sit at 150 no problems/ keep up with all the new mercs and beemas hahaha

 

So even if it isn't required by cert, do it anyway, hubcentric rings are cheap and then you know they are right.

Wonder if there will be as many jobs in the repair certification industry if we follow the ozzys where cars get written off if they need structural repairs.

The icar  welding certification is of my interests.

How much pitting is considered bad on a diff'?  16c1e3b.jpg

it is no longer 100% thickness where the steel tube meets the casting, but the tube is still very thick.

 

Thats still sweet, I saw a model A with a diff that had big deep pits all over it and it had a new wof

Hi Clint.

A chick friend of mine has been building up a b1600 ute for a few years and it's currently at my cousin's place for paint.. I popped in to have a look and was surprised to see that her partner has had a DIY on the seat mounts. There are now two RHS rails each seat welded to the floor from front to rear under where the seats would sit.

It looks to have been mig'd to the floor with no doubler plates.

Am I correct in thinking this is completely un certifiable? She claims that's how she was told to do it but looks like a fail to me (the welding is terrible too)

you don't need a doubler plate if you are welding mounts on as the plate on the other side doesn't really do anything/ the rail isn't directly attached to it/ you are not pulling  "through". But if you are welding it needs sufficient weld area, so depending on the design you still need a footing plate or means of achieving sufficient weld area where it is welded to the floor/sills/chassis - and decent welds of course.

 

So basically it depends on the details, it's pretty hard to prescribe exactly what is ok or not as it depends on the seat mount design and the shape of the floor/what the floor is made of etc.

 

if you are unsure talk directly with your certifier.

you can weld in box/rhs for a seat mount if it goes across the car, ie how a lot of competition vehicles are done, from tunnel to inside the sill, with plates to spread the load.

 

welding it directly to the floor front- back would be a no go. a lot of vans used to be done this way and the floor just cracks around the welded parts

I know this has probably already been asked and answered a number of times but Ive had to resort to using my phone as my computer packed up so it's a mission to dig through this thread.

In regards to drive shaft loops.. Do you need a loop for every universal joint in the drive shaft?

I've had a new drive shaft made up, it's 2 piece the front section has a uj on the gbox yoke, the rear section of the drive shaft has a uj on the front flange behind the centre bearing and another on the rear flange where it bolts up to the dif.

My understanding is the loop is to prevent the drive shaft digging into the ground and causing the car to roll if the uj lets go, if the rear uj on the diff flange lets go the drive shaft will just drag as opposed to catching the ground an rolling the car.

So can i get away with 2 loops? one on the front section of the drive shaft within 150mm of the uj and another on the rear section of the drive shaft just behind the centre bearing?

Cheers

Matt

Drive-shaft safety loops 2.5(8)

A front-engine, rear-wheel drive low volume vehicle that has undergone an engine conversion, or has had its factory-fitted engine significantly modified, such that a significant increase in power or torque has resulted, must be fitted with an effective 360-degree front drive-shaft loop, mounted within 150 mm rearward of each front drive-shaft universal.

 

 

So one hoop per piece, within 150mm of the front universal on that piece.

Hi Clint

 

What are the dos and donts regarding mounting a fuel tank in the boot?

Im mounting a capri boot tank in to my escort with the battery in the left hand well and fuel pump setup in the right hand well, will i run into any cert problems?

 

Im also giving the suspension an overhaul. My engineer was going to get my coilovers crack tested and xrayed but the testing facility said I needed proof of certification before going a head with the tests? Im also wanting to install anti tramp rods and a panhard rod to the rear diff, what are the main cert requirements for when i install said bits?

 

Cheers

Wtf? The ndt guy shouldn't need cert info he is doing ndt on the part and saying yes or no if it has a crack or not. Someone has their wires crossed or is bullshitting you.

The fuel system info is here

crack test man might be talking about a form that the certifier supplies, detailing to what standard the part must be tested to, what it is, what it does etc

 

main thing to think about with anti tramp bars and a panhard, is designing it so i doesnt introduce any bind and is mounted strong enough to do the job. leaf spring and panhard is pretty much always going to bind though
