|

I want to paint my 1959 swing axle tubes, I have serveral VW transaxle gasket sets. Will they work for the side flanges if I take the black plate off to paint them? _________________ http://karmannghias.org/

The side cover that the boot attaches to uses the same gaskets as 356's.
There are different thickness to account for the end play in the axle tube.
So paint away. |

I must disagree with Frank about the 356 and VW axle plates being the same.
The VW version may look and function the same as a 356, but with one difference............ they are cheaper!

It would be pure luck if those cheapo red VW gaskets provided the precise clearance required. OEM came in two thicknesses, while the Brazilian VW gaskets are considerably thicker than either of those OEM German sizes. _________________ aka Pablo, Geary

BB: There could be differences in the VW & Porsche retainer, but the gaskets work very well if a little comman sense it used in figuring
how thick the gaskets need to be. VW has over the years used several different retainer plates. Even offered a undersize one, not sure what that would be used for. As for Porsche, they have only had two as I remember.

I just meant the outer gasket, one one each side (the metal black portion, I intend to leave the aluminum side plate in place) those are the only two that I want to have to replace because I want to paint the tubes. That surface should not impact any bearing clearances for the axle because it is where the boot attaches.
What is the 48 ahead of the gearing sets. Is that a month year?
Further below you can see where they cut off the front trans supports. This was done to create a custom support to put the trans in a VW chassis (custom mount not shown).
What is the best treatment for the housing, soda blast and leave natural?

The clearance of the spherical end of your axle tube is what's affected by the gasket thickness. This is steel against aluminum, and it's a smart idea to get the clearance right.
Original gaskets came with one hole (thin) or two hole (thick). The Brazilian red ones are thicker than the OE thick ones, and have a two hole designation. Without the OE thin ones, you have to have a bit of luck NOT to have an axle tube that is either too floppy or too tight. _________________ aka Pablo, Geary

I have some old German VW swing axle gasket sets from the 60s or 70s. I will certainly measure the old gasket when taking it off. These german ones are all a grey color. _________________ http://karmannghias.org/

This seems like it should be a simple job, but it's often a PITA. Guys tend to over tighten those 6 nuts, distorting the stamped plate and causing an oil leak. The next guy comes along and slathers sealant all over to cure the leak .. etc.
Anyhow, the goal is to have slight drag, without any binding. Always oil those surfaces before checking. I've seen a pretty neat mod promoted for keeping oil on that surface .. three slightly spiralled oil grooves in the hemispherical portion of the side cover. _________________ aka Pablo, Geary

Good tip, if any are distorted I'll check with a straight edge and use my press to touch em up. Thanks _________________ http://karmannghias.org/

Took off the tubes. Good insight, I now understand what you meant be spherical surfaces. In reading my VW shop manual it talks about this Axle Tube Retainer gasket used to set the axle tube end play.
I couldn't find my sets of gaskets, must have given them away during my couple of moves. There seem to be a 10thou and 4 thou thickness gaskets.
I see your point to set the gap so they just move. _________________ http://karmannghias.org/

Here are the different gaskets, ranging from .004" to .010" ..

Frank, it sounds like you might be able to help with an issue I'm having regarding retainer plate differences... could you take a look?
