With the new vented /4 front hub coming out soon (prototype next week I hope), proper torque of the wheel bolts will be critical as in not too tight.
(factory specs okay) There is a safety factor built in of course, but if you don't use a torque wrench and have the strength of a gorilla, "something" is going to give (IMG:style_emoticons/default/sad.gif) (IMG:http://www.914world.com/bbs2/uploads/post-3-1067558082.jpg) |

I torque my nuts at least once a week...wait, that didn't sound right. (IMG:style_emoticons/default/ohmy.gif)
I check the torque of the lug bolts on my car at least once a week. Ah, better. If I'm going to an AX, I will check the torque before I leave the house, check the torque before I run, and check the torque again after the event before I head home...and I mean the lug bolts.

I torque lugs/nuts to spec then after 50-100 miles I check them to make sure then that's it until they come off again.

Yes, in three steps 60, 80, 95.
When I worked in a VW+Audi dealer we had tires changed at local shops. They used the air gun to put the wheels back on and would warp the rotors. That was far too expensive. Did I ever ream them out for the practice. And do not lube the bolts/nuts. That can cause you to over-torque a fastener. It is not a trivial exercise despite appearances. I'm forever having to remind the production team on why the rules have to be followed. DaveP |

Mike, you are asking this for the screw-in version of the hubs, right?
IMHO I believe you should only offer pressed-in type studs with alumunim hubs. There is just too much risk of screwing the threads up over the many times they will be on and off. If someone already has the long bolts for factory alloys, I think they could sell those and make up a good portion of the money to buy 911 studs and nuts anyway. |

For a design such as this, studs and nuts would be much preferred. New nuts are cheaper than a new hub. DaveP |

I agree - I much prefer to play with nuts. Errr..... I mean - it's nice to be able to drop the wheel on the studs while you fuble around trying to get the lugs on - it's hard work holding the wheel up while you get that first lug in with the stock system.

If I'm not mistaken it's 94 lb/ft for five lug and 108 lb/ft for four lug. Word to your mother.

Correct me if you're wrong, but I believe the following to be true:
It is 96 lb/ft for alloys (Fuchs 4 or 5 bolt, Pedrinis, Mahles) and 104 lb/ft for steel wheels. |

We generally do 85 lbs for alloys at the shop. Is that too little?

OK. You just made me dig out my VW/Porsche 914 Repair Guide, a Glovebox series book by Peter R.D. Russek., published by Peter Russek Publications Ltd.
According to this comprehensive technical manual: Standard (steel): 15 kgm (108 lb. ft.) Light Alloy : 13 kgm (94 lb. ft.) Based on this, I would say that 85 lb. ft. is well below spec. |

According to the Porsche Factory Shop Manual you would be mistaken. And thus corrected. Torques in parenthesis are for the 914-6 (i.e. the 5 lug nut pattern wheels). Higher 108 lb/ft torque is for the 914-4 lug bolts. Attached thumbnail(s) |

I see the source of the confusion. You are using an older version of the manual. (IMG:style_emoticons/default/wink.gif)
If you look at the version published in 1974, you will see that Porsche specified: For 25mm bolts (for steel wheels): 108.5 Lb. ft. For 39mm bolts (for alloy wheels): 94 lb. ft. For nuts: 94 lb ft. So, we both are right. Wanna grab a beer? (IMG:style_emoticons/default/beerchug.gif) Attached image(s) |
