Transmission ID...

[lazarus416]

I've looked at the posts I've been able to find on this topic and still am not sure exactly what I have. My wife rides a custom VW trike with a Type 3 engine. I am working on the brakes and the wheel cylinder matches several Beetle years around 68-71, but the drums and brake shoes do not match those years. The numbers I have been able to find/see on the transmission is:

Part# 113.301.103
SN(?) AH 3443 389

By the shape I'd say it is an IRS off of a Beetle, but I need to know which one so I can get the correct shoes and/or drums. (Edited to add a pic of the drum in case someone can ID that instead...)

[VOLKSWAGNUT]

AH cases were used Type 1 69-72 . Main ID features should be CV joints and dual removable side diff covers. 4.125 ratio.

As for brakes and hardware.. .. its custom so really any year combination may be on it.

Add some pics and we may can help ID parts for you.

I realized something that I had not noticed before. The holes on the interior of the drum do not match the outside. Did VW brake drums normally have a separate piece for the lugs? Or is this a 4 lug to 5 lug conversion? (Cause I have yet to find a picture of a drum that matches this one...

[VOLKSWAGNUT]

They look like Beetle drums with 4 to 5 lug adapters on the outside..


IMO .. buy drilled drums for the right 5 lug pattern and loose those adapters.. Just to note if you remove the adapters it will narrow the rear track by the thickness of the adapter.

Any idea what year? The brake shoes O'Reilly's shows for them has the wrong radius for this drum. It only makes contact with the center half of the shoe. The ends bend too far away from the drum to make contact. As best as I can figure, the "AE" seems to indicate that they are off of either a '71 or '72 Beetle?

[VOLKSWAGNUT]

How deep are the brake shoe surfaces? They do look deeper but could be the angle.

also... What is the diameter?

Inside to inside of the drum...9 3/4.

[EVfun]

All the VW Bug brakes are the same diameter, 230mm new, and 231.5mm maximum should be the brake drum diameter. The brake differences are in width and seating style. Looking at the drum and transaxle information it is most likely you have 1968 up type rear brakes, 40mm wide shoes.

You posted just ahead of my post. Based on that size I would suggest you have Type III rear brakes (Squareback.) I'm not sure how to determine the year, but I think later, 1967 and newer, because of the 4 lug drums.

Looking at the diagrams you posted, the brake shoes most closely match the 270's, but the ends are slightly different. 315 is what the parts store was showing, but when I set them inside the drum (I happened to have it with me), the ends of the shoe didn't even come close to making contact. Both ends were probably at least 1/4in off the drum.

[VOLKSWAGNUT]

9 1/6 to 9 3/4 difference is a lot..
If someone turned 1/4 out of that drum it would equal 1/2 all around.. ..if so.. they really need their ass kicked for it..

Forget the drums for now ...
How do replacement shoes compare to what it had..??

.. they are most likely 68 and newer Beetle..

That's my problem, because of the curvature, the replacement shoes only make contact on the middle half of the shoe....

[VOLKSWAGNUT]

[lazarus416]

The shoes I have are not BAD, but since I am replacing the wheel cylinders I figured I would go ahead and replace the shoes too and start fresh. Her brakes have never been the greatest and I finally figured out that 1/2 of one of the left cylinder was bad and the right side was out of adjustment. The thickness of the shoe you see in the pic is about average all the way around. I can put the old ones back on if need be (she doesn't ride a whole lot anyway), but I was trying to ID what I had.

Face palm to all the experts here,,,, you have t-3 drums. Tell the parts monkey you have a 1969 squareback.
