I'm leaving an extra post free in case I forgot a future topic. The reason I just posted the subject of the article for now is so people won't have to wade through several pages of posts to find the info they are looking for when it is finished.

ZF LSD for IRS

Let’s see what I can add here just off the top of my head. I'll start with the biggest pain in the ass. The Autostick. The VW Autostick breaks down like this. It is a three speed manual gearbox lubed with 90w gear oil and a standard type clutch. The clutch is operated by a vacuum servo controlled by a set of trigger points in the shift leaver. These trigger points operate the servo control valve that supplies engine vacuum to the clutch servo. To keep this vacuum constant there is a vacuum accumulator tank under the left rear fender. All this monkey motion is coupled to the engine through a torque converter that uses ATF. The converter gets it’s pressure via its own pump. The ATF pump is piggybacked on top of the engine oil pump and plumbed to the converter through a series of flex and hard lines. There is a tank for the ATF under the right rear fender. IMO one of the biggest pieces of crap ever produced by VW. I made good money fixing them back in the day. But you would never want to use one in an off road car. The reasons are many but mainly it's just plain unreliable.

swingaxle transaxle. All 6 volt with short axles up to 1967. The 1967 trans was a one-year only trans due to its new long axles. But it still used the narrow 5 lug brakes so the splines for the brake drums were short like a 6volt trans. 1968 was one year only as well. (IRS in 69.) the new 4 lug brakes were wider so the axle splines for the drum were longer. These axles are also the same dimensions as the type 3's axles but the over tubes are a little different because of they're sway bar mounts. Type 1 is bolted on and type 3 is welded on.

that's all for now. more later. I got to get up early for work :)

throw in www.2weddle.com , just in case they ever get it running

I'd like to clarify a couple of errors in the first post.

The first Bus IRS trans in 68 is called a 113 type Bus trans. Same for those up to 71. This is because all the parts associated with the 4 forward gears and reverse are exactly the same as what are found in a Beetle 113 trans. Exceptions are gear ratios and tooth configuration.

Then in 72, the 002 Bus trans came out. The individual gears were all completely re-designed and are called 002 gears. These were used to the end of 75. Beetle gearboxes with only one side cover also use the exact same 002 Bus type gears.

I have this exact tranny but I am running 930CV's. The tranny hatched on me not to long ago and I just picked up a new one. Anyway I'm switching them out and I'm having a problem getting the flange off for the CV joints I removed the seal and the "C" shaped clamp around the inner flange but the CV flange will not come off.

Is there a special tool or something to get this thing off or what??

Thanks in advance for any info......

When fitting a pre 64 bus tranny to a baja, how much does it widen the rear by?

try a prybar under the drive flange, use one of big screw as the pressure point for the prybar.

mine came off pretty easy with out a prybar though.....

I'm not sure on that one. I would think about 3 inches or so....Just whatever width the reduction boxes are. I will try to find out when I write that post about it.

Wanted to add to Bruce's post above...the '68 three-rib bus trans is a good one to avoid. Aside from being weaker, many rebuilders don't carry parts for it anymore. It can be identified by looking for 6 nuts behind the CV flange, as opposed to the 2 screws on all later ones.
Compare this to the red one...

Guys, here are two pics of a Synchro front diff I found for sale in the classifieds. This would be great for a 4x4 project, if you could find one.

Also, if you will check the thread HBB linked to in the Lockers and LSD's post a few posts up, I added some pics on the Synchro locking diff to the other thread.

'71 sounds about right. I'll have to check a manual and verify that.

90Volts, "freeway flyer" means that the gear ratios allow the car to go faster on the freeway.

Here is a pic totally unrelated to the above post...
