T1 generator stand
I've worked on 4cyl Porsche motors for many years and wonder why on
these motors you can easily remove the generator/fan assembly while on T1 VW motors it's more difficult, due to the fact that the assembly must be lifted, as opposed to slid off as with the Porsche. The photo of the typical Porsche stand (link below) shows the rear slots which, when the front 2 bolts are removed, allows sliding away from the 2 rear studs (which remain in place). Any thoughts? I'm tempted to cut some slots in an old VW stand to try it, but it seems that after all these years and aftermarket modifications to these VW motors, there must be an obvious reason I'm missing....different metals, etc? TIA Bill http://picasaweb.google.com/WFBowen/...09670232814770 |

T1 generator stand
Usually the 912/356 engines don't have an intake manifold blocking the rear
of the fan housing since they are equipped with dual carbs. And aren't the 12V generators of these Porsche engines smaller than the typical air-cooled VWs. IIRC the Porsche 12V generators are as small in diameters as the VW 6V generators.

Interesting idea however, I am going to do that on my next build. (Dual carbs) Jan |

T1 generator stand
On the Porsche, the forward (towards front of car) two studs stay on,
the rear 2 are bolts. From what I can tell, the threads are cut directly into the alloy - no inserts visible. I suppose that the same can be accomplised on the VW by just removing the 4 studs and replacing them with accurately measured bolts. The beauty of the Porsche version is that the two studs serve as a locating aid when sliding the unit on. Also, I see the point single carb intake runner - forgot to mention that the 2 VW motors I have both are dual carb. As for the generator physical sizes, the Porsche units (there are 2 12v versions-lg & small - and the 6v) they're very close in size, if not exactly the same diameter on some versions. The VW alternator, of course, is a whole different story. Bill |

> Michael : The Porsche version does all for pretty much sliding the assembly off to the rear. In this photo: http://picasaweb.google.com/WFBowen/...nd/photo#50485... the circled slot has the opening facing the front of the car...you just slide it on until it stops on the slot. The only tilting I recall is to keep the gasket from sliding around too much, but it was never a big problem. Bill. |
