Had to make a hex out of a grade 8 bolt that needed to be ground down just a bit. Fit really snug as I miked it in. Frenched up a couple of nuts with some "J.B. Weld." Got a 15/16" deep 1/2" drive impact socket with a Posi-Drive shape (Orchard Supply had Craftsman one for $11). Impact gun was next step.
Before the gun, I took a long 1/2" breaker bar with a 3 foot piece of iron pipe to try and make the thing budge. It made a huge POP and squeaked like hell for a few turns. Very odd even though I soaked both sides with "Break-Free" and allowed to sit overnight along with the special tool that was setting up.
Looking at the axle, it may have had some Lock-Tite on it, but is seems a bit corroded where the nuts resides. Maybe water? I don't think BMW's like getting baths as the old RT showed corrosion on some of the plug in wiring connections. New ones seem better for that.
Only other thing I could conceive of was the fork may have gotten a bit tweaked in the fall over as the impact made a good ding in the old Moto-Light that was mounted to the brake caliper?
Anyway, I took the impact gun and ran the thing in and out a few times (fine valve lapping compound on the threads) while the wheel was off to loosen it up a bit. It now goes in and out as it should.
Front Avon tire took no weight at all. Stock Metzler Z6 had maybe 30 grams on it. These things look more triangular in appearance so they should fall into turns easier. Seemed like they weigh less than the Metzler did too (lack of steel belt?).
Now out to adjust and aim the Moto-Lights tonight and get some canyon twisting in before dinner before that.
