OK Sudsters, here's the lowdown on the driveline angle situation.

Approximate measurements show my engine and transmission are set at an angle of approximately -3° relative to horizontal (that's nose down).

Using the Alfasud cutaway drawing on Tim's Alfasud site, I measured the angle of the engine and transmission in the 'Sud as +2.1° (that's nose up), relative to the sills. There's no accurate ground reference on the drawing.

So now all I need to know is whether or not the 'Sud sits level on the ground - i.e. are the sills parallel to the ground, or does the car sit with a bit of nose down?

The factory promo pictures suggest it sits level...

If the Sud sits parallel to the ground, then I need to change my driveline angle by 5°. If the car sits nose down a bit, then maybe I only need to change the angle by 2 or 3°.

I din't have a Sud I can look at, can anyone help me?

Thanks everyone,

Lauren

Hi Lauren,
Looking at my 33, I would say that the sills are parallel to the ground. However, I still think that the angle isn't that critical. My Minari has been jacked up at an angle of about 30 degrees ever since Stoneleigh and not a drop has come out of the gearbox (this is both nose up and tail up for days on end)
Hope you get it sorted,
Mark

Thanks Mark - I'll assume parallel then which means I need to shoot for +2° relative to horizontal. I need to make some accurate measurements to establish the actual angle of my chassis relative to horizontal, as I did the last set of measurements using a spirit level and protractor, but not on a necessarily level surface.

Hopefully I will find that I'm only a couple of degrees out.

Something must be wrong with my set-up. You don't get gear oil coming out of the halfshaft for no reason. And there's no oil seal to blame either - the oil thrower is supposed to be enough. My contention is, at this driveline angle, it isn't.

I think there must be a difference between jacking the car up (possibly for days on end) and driving it for mile after mile at this angle (over 300 miles this week, more than 250 yesterday alone).

I'll let you know how I get on.

Thanks Pat - I'm really just after a quick eyeball to see if 'Suds sit absolutely horizontal, or if they nose-down a bit.

Worst-case they are horizontal - that means I've got to make a change of about 5°. If the 'Suds are generally nose-down then I can get away with a smaller change to my engine mountings...

Don't be surprised if you see me skulking with a tape measure at Stanford Hall :cheese:

As all the suds that are still alive are rather old the springs will have sagged a bit and may well be lower at the front due to the weight of the engine. Or like my cars they will no loger be original and will have dampers or springs changed. Cars with Bilsteins, which are gas shocks, sit higher than cars with oil dampers . So I would judge ride hight by the factory promotion photos you posted and they show the cars to sit level.
