engine and drivetrain Alpina Diff Cover

[Captain Manly]

Better yet, a Solidworks file?

Hi guys,

 

Here are the pics I promised.

This is a novel design reproduction more based on oil capacity than on fins being as large as possible. Note also the position of the 2 big holes for the connection to the car frame....

It also has connecting holes for an oil cooler and temperature sensor.

All the Alpina E21 ones I have seen up to now are missing most of the fins anyway because of hitting road surfaces or other obstacles...

Now for the good news.

I can still get access to the original positive wooden molds/casts (whatever you call those things). I've asked my aluminum pouring friend what a limited run of making these would cost per unit.

We assume it will cost (for a run of at least 10 pieces), about 300 EUR a piece, unmachined.

If the need is high, we can even extend the fins to look as sexy as the Alpina E21 system.

If I can get 10 people to pre-order I am willing to have it reproduced. The machining and surfacing/drilling will have to be done by the buyers themselves. I haven't sourced a company yet to do this...

More pics can be made if desired...

I can also fit it to a diff sump if desired.

Do let me know if interest exists.

Put my name down. [emoji1360]

Nice!  I've already got an original Alpina, otherwise I'd buy one of yours for sure.

[andreb]

For 300 Euro, I'm in! I don't even need one but it will look great on the parts shelf. Let me know if there is enough interest and I'll send the money.

I could be tempted by one of these...

I am in.   

 

Rough cast, so that would mean machining the bolt holes, diff mount holes(?), and mounting face.

[banaba]

Put me on the List. i want 2 Covers.

[02Anders]

Oh what the hell... I'm in for one too!

I'll ask one of my mates whether he wants one too - I'll get back to you on that...

[Driv3r]

7 so far, he needs 10 orders

Hi Tom,

and how much will be the machining? Do you know the precision and qualitiy of the cast aluminium he is able to produce? There are really big differences!

I'd be in

I'd be up for one subject to the questions from whs.de

 

Cheers, Nick

[halboyles]

Agree with Nick about  the question from whs.de regarding metallurgy.  Some assurance regarding the composition and QA of the casting would put me in the yes column.

He specifically said that it would be rough cast and not machined, so he does not need to quote that.

 

I'm not sure how you would quantify the precisioon or something ambiguous like quality.  Are you asking what alloy, is it a fresh mold?
