I recently looked at a case with a part number 081-301-051-C    The case was wrapped in plastic and had one of the moisture aborbsant towel in the wrapping.
The guy who had it said it was a mag case. How do you tell visually if it's mag or the new alum case?
any feedback would be appreciated.
 thanks and Merry Christmas!

I've read the white rhino case (aluminum) is roughly twice the weight of a mag rhino case. Shipping weight for the aluminum case is 30 lbs.

.
I checked on another forum and was given these numbers
Mag 12.2 Lbs

Alum.  18 Lbs

 it's interesting that the part numbers do not designate if a mag or alum.

Visually you should be able to tell if the case is an aluminum one. I'm going to use one in a project.  Has to be stronger than MAG.

I've yet to break my 12 year old Rhino case, so i'll have to keep trying.

Rick,
there is a batch out there of the 1st aluminum version that appear to be bad,material to soft so side covers come loose,and when used in high hp application have split in 1/2 :o  One version the casting is rough,the other smooth but I cant remember which is good and which is bad right now,i will try find out and let you know

cheers richie

Hey Richie....I would welcome your input on this one.  I ordered one thinking Aluminum had to be better than Mag in terms of strength. Then again, type of aluminum makes a difference. If you have some insights...I'm open to your input.

Heres 2 quotes from Mike herbert,this should give the info needed

I have seen some issues with the Alum. Rhino but it was only in the begining and the Cases had
a realy bad finish on them.

these rhino cases come with what size of clutch shaft? old or new style?

i noticed these cases are very similar to the gearboxes found in Brazilian Type 2s.

Would that be the ones with IRS and reduction boxes?

16mm

A trans builder friend of mine also stated that the aluminum AUTOCRAFT trans housing when first out had really tight pinion bearing bores. I have not heard that of this case. In fact, when I get my case from CB I will have him compare it to the $800+ AUTOCRAFT trans case.

I personally like how Porsche uses a steel race for the pinion bearing in their housings. Another thing about the AUTOCRAFT trans case is it uses the 4 bolt pinion retainer instead of the later larger pinion bearing with the screw in retaining collar.  Many trans builders prefer the later bearing for its width and support of the pinion bearing over the earlier 4 bolt narrower bearing.  I cannot remember what the RHINO uses for the pinion bearing...but I believe it is the 4 bolt.

Hi rick

The new autocraft cases are much stronger than the rhino aluminium cases , so they are worth the price.

When you get your case, send it to DK Machine in Norwalk CA.   Don can machine and press in a steel ring that he makes.  It will allow you to use the late bearing in the 4 bolt case.  As a side note.... many of the trans builders I have talked to prefer to use early cases over the late for drag racing.

the ones i find in this part of the world does not have reduction boxes.
