Type 3 drums & short axles...?

[Kaferdog]

I know theres gotta be a thread about this but can't seem to find it ..!!...How much do you need to take off to fit on short axles...??...

[stealth67vw]

About 5/8" or 16mm.

[Lee.C]

Do you mean on the "snout" of the drum/hub

[DKK Ted]

Yes, they are. 66' short axles, I'm going to take the hubs to work to shorten them for the 66' axles for Kaferdog. So I need to make sure before I cut them.     Ted

Yes the snout..Thanks ..I heard it was 5/8 just wanna confirm it ?

[nicolas]

yep that is it. same for drums with 4 lug and 5 lug type3 drums.

[rick m]

The 5/8 figure is right. I ran type 3 drums on my 67 cal looker and used 66 axles too. I love the width of the brake shoes on the type three.  Great braking power.

And.......the rears work even better with a larger (as in front) wheel cylinder to get a better brake biais when run with small front and larger rear tires.

or look at the square back cylinders they are a bit bigger then the one for a notch or fastback. but it must be original Vw items as nowadays i see they sell only one size for all models.

yeah I heard that super Beetle are I think 23mm...?...and they were the ones to use..!

[DWL_Puavo]

1302 front drum brake cylinders are 23mm and fit great with T3/4 rear drums. Also, they are dirt cheap when bought as a new - same thing with the "drum part" of the 2-part T4 rear drums. The hub part itself is best as old original - much stronger than, for example, Kärscher-made rear disk brake kit's hub.

Another question regarding this conversion...

I have Type 3 backing plates on their way to me.  My '58 still has the original bearing retainers, which should have an oil damper (?) on the outside to collect any oil which escapes past the seal.  I don't have these. I was thinking that whilst things are apart I should therefore fit the later style retainers which direct any escaped oil through the hole in the Type 3 backing plates.  However, I'm told these retainers come in various depths...logically I should wait for my backing plates to arrive and check what depth I need with these in place, however I have a deadline for getting everything together!

Has anyone else done this conversion/update who can help?  Is it worth making this change given I currently have parts missing?

Also, the one other  part I don't have is the short Type 3 springs which are on the lower point on each shoe.  Does anyone know if these are similar to any other VW (Type 3 parts are hard to find here and we didn't get Super Beetles with front drums either which I think may have used the same setup)?

These are the current bearing retainers:




Many thanks

Gday Richard.

How about something like this perhaps?

[RichardinNZ]

Unfortunately the Springs are different in the Type 3 kit.  I was hoping they may be similar to something used on a Beetle ot Bus as it'd make it easier to obtain here. 

This is the Type 3 kit:

Unless T-3 backing plates are thicker than T-1 backing plates, you should find bearing retainers from a '64 to '67 Beetle.

Many thanks for the link.  I'll have a good read through the information and see what I need.

If Super Beetles have a 23mm front wheels cylinders... what size do Squarebacks have in the rear vs front? What size do  Notch/Fastbacks have?  I'm curious to know the comparison. I'd assume that Super Beetle front wheel cylinders are easier to come by that Type-3.

My backing plates arrived Today; hooray.  One of the springs on the adjuster is broken;  boo.  Looks like I was over optimistic in hoping to finish the car for Easter!

Does it look like one of these . . . http://www.wolfsburgwest.com/cart/DetailsList.cfm?ID=211609185a

[RichardinNZ]

I think the Type 3 ones are longer and wider.  The seller has said they will send me one so should all be good in the end.  I just have to have patience and accept I'm driving our T##ota minivan to the NZ VW Nationals.          I do admit that then 3 hour drive will be easier in that than in the Bug with 4 people plus luggage!

[Chris W]

I got springs out of a Bus kit I believe. I just bough a few till I found the right springs. It took a few kits to get all the hardware.

[RichardinNZ]

Hi Chris
Vintage Warehouse have the spring kit...unfortunately shipping from the USA isn't cheap but probably still more cost effective than having to purchase a number of different kits.
I like the weight saving on yours; very neat setup.  I'm thinking that as the pressure is now off in terms of time, that I'll get the backing plates powder coated for mine.
Thanks
Richard

[RichardinNZ]

Back to the springs....I just can't bring myself to pay $27 shipping on a $16 part!  Does anyone have any spare lower springs (x4) they would sell or leads to a which bus springs are similar?
Thanks
Richard

[RichardinNZ]

OK, after months of too much work and too little time to spend on the Bug I thought I'd made some good progress on this, having sourced sensibly priced hardware etc.

However, somehow I have managed to snap the new adjuster leaf spring which was welded to my right hand backing plate...does anyone have any replacements or know where I can find one (or perhaps 2 just in case!)?
Thanks
Richard
