944 n/a hubs on 412 spindles..project

[Wally]

Since I wanted to use vented disks up front too, I am going to try to adapt 944 (n/a, early) front hubs so a type 1 bearing can be used for an inner bearing and a spacer bushing will be used for the outer (944) bearing as the 412 spindle is a litte smaller in diameter and not the same as a type 1 spindle. It does use the same type 1 bearings though

Here is the adapter ring on top of the still original 944 hub:


This is after the hub was shortenend by 6,5mm and the inner part openend up for a shrink fit with the adapter piece:


After heating the hub in the oven and putting the adapter ring in the freezer, it fell right in


Next job is to install the wheel bearings and try it out on a spare 412 spindle...

Well, the 944 hub fits nicely, but could have used a little more room on the nose for the retaining screw/clamp and washer. I might had better shortenend it by about 10mm I think now, but its work this way as well

Tried the 944 caliper, but its too close for proper fitment:
(pity, as the bolt hole spacing of both calipers is exactly the same...)



This also leaves open some other disk and caliper options hehe..
To be continued.

Wally...you got too much time on your hands. Great job though!

I did something very similar, but to fit 1303 hubs...

Hi Wally

Nice work. This is what I did to adapt Porsche callipers to my 1302.
