SVA Shock nightmare

[Bonzo]

Hi to all,

I have been looking at UncleFista's homepage. www.bradford7.co.uk

I read with great interest the section titled SVA Result. The two items that cause me the most concern are the failure of the shocks and the steering arms on the front hubs. Both for a radius breach ( Less than 2.5mm )

Surely all coilovers are of a similar design

I have looked at the Sierra front hub. The steering arm on this also has no radius of 2.5mm on the exposed edges.

Do we need to modify them with a little linishing or was the SVA Inspector having a bad day.

UncleFista's SVA Fail serves to show us all the standard required for an SVA Pass.:

The prototype has unmodified steering arms and it wasn't mentioned at the SVA, I suppose it depends on how keen the inspector is being on the day, you could argue that as they're behind the track rod ends that they're not "contactable".

The coilover shocks need a large collar made from split heater hose over the lower spring adjustment collar and the adjustment knob, these can be tie-wraped on so long as the buckle of the tie-wrap is placed at the rear of the component. Make them big enough to cover the bottom through bolt on the shock.

Cheers

Good points Chris,

I would not have thought about heater hose over the adjustment collars.

UncleFista's SVA Fail serves to show us all the standard required for an SVA Pass.:

The coil-overs were fixed for the retest by putting a couple of Radio Controlled car tyres over the threaded body of the shock, the steering arm radius was sorted with a couple of minutes with the angle grinder (and look better for it too )

It's all a bit of nonsense really, we never expected it to pass first time, it was just a "punt" to get a list of problems to fix

The vast majority of it is common sense

Good luck !

Hi UncleFista, Nice to have your input.

I think I will be ultra keen on all things sharp. As you say a few moments with a flap disk in the grinder may save a lot of hassle at SVA time.

Had my fair share of dissagreements with MOT inspectors over the years. I cant Imagine an SVA inspector changing their point of view in the face of alternate logic from the person presenting the test vehicle.

My nearest SVA testing station is a 200 mile round trip. Not too keen on doing the run twice.

If the exposed suspension components are now under tighter scrutiny then perhaps take a leaf out of Dax's book. They run a tube across from the nose to as near to and in front of the wheel thus making it the forward part of the body. The dreaded 100mm sphere can't get past it to the sharp bits
