Saw a post by Guy aka 914GT about using Type I CV's since the 914 specific CV is NLA. So far Guy has not had problems and he is running a 300+ HP V8 (IMG:style_emoticons/default/burnout.gif)
So I bought a set of 4 (average price is $40 or so, Eric Shea has them in the resource area) They are not a 100% bolt on item, they are lacking the 10mm spring pin holes so 2 of the 8.5mm(?) thru holes need to be drilled to a depth of 10mm (.40") Normally I would use my mill, however I had a job setup on it and I didn't want to re-do my fixtures for that current job so I used my lathe. Not the prettiest tooling, but it works (IMG:style_emoticons/default/smile.gif) 1st pic is stock CV with un-mod'd CV on the right, lower CV has 2 holes opened up for the spring pins. 2nd pic is of the fixture, the 2 silver posts are for locating the CV, these are turned down to match the diameter of the thru holes on the CV, then I use a bar to clamp the CV down. 3rd picture shows CV having hole cut. 4th picture shows "step" cut into the CV for the gasket, Guy and others have just used RTV with good results, but I wanted to use the PITA gaskets (IMG:style_emoticons/default/screwy.gif) |

the dash marks in black ink are so that I re-install the cage w/balls into the correct CV and at the correct orientation......

Hey cool. Good to see you're keeping busy.
Do the girls sleep to the sound of the lathe now? |

Since you have the lathe out, can you turn them for the gasket recess?

mike, i guess this is more economical than 944 axles! they have same internal spline? so you just use the 914 axle? cool. |

Last picture shows the new relief for the gasket....the CV on the top right hand side.... arron, I'm using 4 lug parts still, I think the 944 parts have a larger OD for the CV. yes, the spline count is the same as is thickness, the only deviation is that the Type I has a slightly smaller OD on the end opposite of the spring pins where the boot goes, I see this as an non-issue since the mounting bolts will center the boot. |

That's it??? Drill some holes and bang in the roll pin. Perfect. When do you go into production?

Did you fill the two remaining holes with silicon so the grease doesnt travel through the pins and out the CV boot cover?
Just a thought: the 914 tranny is a VW part. Did anyone check to see if you could use regular IRS bug output flanges on the a 914 tranny? You would'nt have to go through any of this (at least on one end!) B |

and while you got your lathe all fired up, why not turn down my second axle?

The 914 CV has a thru hole for the spring pin, they too would have the same issue. Just a thought: the 914 tranny is a VW part.

Seems like more work and more cost to replace the output flange. B |

QUOTE Seems like more work and more cost to replace the output flange. Anyone checked to see if we can VW stub axles at the control arm. The whole idea would be to utilize a complete VW BUG IRS axle assembly one day so people could bolt something together. Not drill/mill/lathe something together. I have used a drill on 930 CV's for the early 911 spring pins. I know it works. The main question is: do the VW parts work? B |
