I got some new front rotors, wheel bearings, and seals. I've seen a tread on how to do this, but can't find it. The seating of the rotor, how tight. Also went to adjust rear inner clearance on rear pads, but there where no gears in them, lol, so i called PMB, and there sending me new gears, copper seals, and the new better caps. Any suggestions. (IMG:style_emoticons/default/blink.gif) I've done rotors before, but not on the 914. Just want to make sure its done correctly, thanks.

I think the perfect method is the following:
1 - Overtighten the nut (while turning the rotor) to verify bearing races are seated. 2 - Loosen the nut until you can get some free play in the wheel (top & bottom wiggle just barely). 3 - Retighten the nut until no noticeable wheel wiggle. 4 - Verify that you can move the washer by prying with the tip of a screwdriver. Of course you can tighten the nut until you have no wobble, but overtightening means you cannot move the washer. No perceptible wheel wobble PLUS able to still move the washer = "just right". I then drove the car a mile or so & jacked up the front and checked, and they were still just right. |

(IMG:style_emoticons/default/agree.gif) Don't forget to re-check after a few miles like Stu mentions. Same goes with CV bolts in the rear if you don't have them safety wired. They can back out even after you think you have them torqued done. |
