ok delving into the realm of CV's i have found some tid-bits.. thought I'd share
They are really called Rzeppa Joints
here is an artile on the invention and physics of a CV joint. http://www.niehoff.com/cprotest/cpc12g.html

Approx Max Joint Angle
930 28'-30'
181/T4 20'-21'
Bus 17'-18'
beetle 12'-13'
280Z 20'-25'

Joint thicknesses
Thing 1 1/4"
T2 bus 1 1/4"
vanagon 1 1/8"
beetle 1 1/8"

Some Axle lengths
beetle 16 1/4"
T2 bus 18 3/4"
T2 to T1 15 5/8" (for T2 tranny in T1)
T2 W/3" arm 17 1/2" (for T2 tranny in T1)
T2 W/3X3 arm 19 3/4" (for T2 tranny in T1)
vanagon AT 22 3/8" (long axle)
vanagon AT 20 1/2" (short axle)
vanagon MT 21 1/8"

Bug and Bus CV joints don't have the same ability to operate at as severe a drive angle as the type 4 joint used in the type 181. Thus will operate up to an angle of approximately 21 degrees, versus 17 degrees for the Bus joint. However, as a temporary fix, the Bus joint (VW part no. 211 501 331B) can be made to work. <HR></BLOCKQUOTE>

I hope this clears up some questions, It has helped me.

Here is a good article about clutches on thesamba.com. Very useful info, and it goes into more detail than my post about throwout bearings...

how high of a r&p gear can you get for an 002 trans? are there any lower gears for an 091? i rode in my buddys buggy this weekend, he has slightly smaller tires than me, and his 002 is geared WAY higher than my 091. he is running a turbo 1600, and while i was in 4th wishing i had a 5th, he was cruising in 3rd...

Tako do you know what gears you have cause the 002 is geared lower, if stock then the 091.

scotts post on fore/aft cv angles

scott the viking wrote:Get yourself and angle finder...they are cheap. With car level, set the finder on the axle. I don't remember what the max angle for your cv's are...it's on the blind chicken site...Anyway...you can't go to the max degree...because you have to figure in the degrees that the axle is aft of the tranny. In other words...for every degree the axle is pointing toward the rear of the car...count those degrees as 1/2 degrees and add them to your total... Hope that came out easy to understand...I am in a hurry. If not...I will explain it better a little later.

Here is a thread with info about transmission casting numbers...

Using a Type 1 engine with an 091

I want to add this additional information, which I have recently learned:

If you want to use the 091 with a T1 engine, there is no need to modify or switch any parts around. However, if you do this you must use the 091 bell housing and 091-only starter.

If you want to use the Type 1 style starter (it's cheaper and easier to find) with your 091, you must do one of the following:

Get the 002 bellhousing and input shaft, and swap them to the 091.

Get the 002 bellhousing, and trim the 091 input shaft. IIRC, you need to cut about 1/2" off the end.

There is also one other option that I have heard of, and that is to simply have the starter area on you 091 bell housing milled down so that a Type 1 style starter can be used. However, I do not remember the specifics of this modification...

I've never done it but 0.25" is what I've been told many times

Richmond Lock-Right

I don't know much about this one, but it seems like it would be worth the money.

http://www.richmondgear.com/01pdfs/ptrax.pdf

I bought this 091 carrier with the lockrite in it. I put it in my 002 3 rib.

All i can is you point it and it will go, get a push sometimes when riding in the woods. Got to use the clutch or let off the gas and it will turn. I might be getting a baja if so then it might turn better in it.

There is a way to put a bus box in a bug WITHOUT a 10-degree mount, rasing the shifter or using one of those crap adaptors.

It is a intermedate housing that lets you use the bug nose cone on the bus box.

It is very popular in the drag racing comunity. where it has proven it self to be bulletproof.

http://www.thesamba.com/vw/classifieds/ ... ?id=140691

It might seem spendy but how much do you have wraped up in the 10-degree mount fab work etc..

I like it .. So that the nose can mount in the stock postion... But what rear mount do you use with it?

If anyone would like, I have an 091 noseshift and an 091 midshift both torn down at the moment I can take some pictures of.

Let's see what ya got. Thanks.

What would you like to see. I've got pictures of the 091 midshift reverse gear setup and I can take some of the 091 noseshift showing the differences.
