A while back I bought the modified type 1 CV's. Just getting to think
about installing. Look at the pic where the outside is machined down. (This is not the modification for 914, this picture is from online of normal type1 CV.)  I can't really show it with a picture, but the flange is built to the larger diameter, so it doesn't match with the machined area. This seems stupid. I guess when bolted down it should still retain the grease, but why is it like this? |

The boot goes on the other end of the joint. The cut down portion goes against the flange of the stub axle. The Cap'n

But the other side has the recess for the gasket.

Modded CV parts are outside my field of expertise, and I apologize for the apparently erroneous answer. Where's you get the parts?

The modified version is installed 'backwards' from the Bug orientation. If you're worried about the boots leaking, you can try some sort of sealant. They've all worked fine for me.

put the gasket on the boot side and sealant on the stub axle side.
The modification is so the CV will fit snug in the stub axle...not the boot. Also, pick up some paint gun cleaning brushes....small wire brushes...and super clean the threads with the brushes, cloths, brakclean...get them all metal, then use locktite on the threads. Rich |

Thanks all, I'm pretty sure these are the pmbperformance.com
ones. I'm going with the McMark way for installation, in fact I don't think it's even possible to do otherwise. Not only would the gasket have huge overhang on the thin side, also the pin holes are only drilled out on the thick side. |

I have never had one loosen as long as a new Schnorr washer was used
and most of the grease kept out of the holes. QUOTE(McMark @ Feb 21 2011, 10:23 PM) QUOTE(r_towle @ Feb 21 2011, 02:34 PM) l, then use locktite on the threads. Rich ACK! No thanks. (IMG:style_emoticons/default/tongue.gif) |

Another similar thread made me look at the pic Chris has at
Tangerine Racing, where he also sells the modified Type I's.  He adds an o-ring so the flange is tight at the sides. |
