greese fitting in neck of frame

I think I over tightened the spanner nut and let water into the top bearing......found a little rust during the last inspection on the top bearing. Cleaned it and packed with grease, just need to order a new one. Buddies' 06 had the same problem, but don't think he over tightened the spanner nut, anyone have the same issue?

Quick question about that nut. The manual for my 250F (08) says torque spec for that thing was 105 ft/lb. I couldn't get it past 60 ft/lb. 105 seems a bit much too...any thoughts? Maybe a misprint?

Hole drilled in center of bolt.
So, you drilled holes up the axis of the bolt, then cross drilled it? Did you also drill the inner bearing sleeve so grease could get from the bolt side to the bearing side? How did you align the holes in the sleeve with the holes in the bolt?

Tricky work if you can do it, but complicated to the point where it's probably beyond the skill set/equipment capabilities of many home mechanics. It would seem to weaken the bolts significantly, too (the cross hole more than the center hole)

What exactly do you mean by saying that you "couldn't get it past" 60 ft/lb? Weren't strong enough? Bike kept falling over? Nut felt like it was stripping?

The torque actually is 105. What happened?

The bolt on the '00 426 is drilled thru the center from the factory, I cross drilled into that passage and then a groove to the brg, the linkage is way over engineered, If I get time I'll disassemble and take pics of the bolt and race. Some tough drilling and a steady hand. Mike

Justin 314, the spanner nut I was referring to is right above the seal. Spec is only 7 nm for that nut.
