05 CRF 450 front axle nut

19 posts in this topic

You sure motofix? I have a couple of snap on hex sockets and I thought my 20 and 22mm were too small. I'll check in the morning.

Is it normal when tightening the front axle nut for the fork leg to creep in toward the hub a little? This happens no matter how much I tighten the two pinch bolts on that side. I'm always concerned that the nut will loosen off during riding.

Try tightening the nut first, then use the two pinch bolts to hold it. After you have that, you can align the right side.

Aaah, that makes sense! So, do you temporarily tighten the right side pinch bolts to keep the axle from spinning while you tighten the axle nut, then loosen again, tighten the left side pinch bolts, then center forks and re-tighten the right side pinchers?

Tighten the axle nut till axle begin to spin. Then tighten pinch bolts on left side (facing bike) Then tighten axle nut to spec's, then tighen pinch bolt on right side (brake disc side)

Torque the axel nut first with out tightening any of the pinch bolts. Once the axel nut is set then grab the front brake lever and compress the forks up and down a few times. Then tighten the pinch bolts to spec. (This is the proper way my man)

How about using an allen key to hold the axle while tightening the nut? I would say that is the proper way to do it, but your way works too.

My suspension tuner showed me how the slight burr on the axle head (from prev owner) made the fork bottoms pull to gether when the axle was tightened up. This make the front suspension harsher as the travel is used as the forks become like a slight vee. he machined the burr off the axle so it seated in fully.

you are supposed to torque the axle before tightening any of the pinch bolts. this requires a special tool for the large hex in the axle.

then you tighten down the non nut side pinch bolts, cycle the forks or spin the wheel a few times and hit the brakes. then tighten the other pinch bolts.

at least im pretty sure that is the correct way.
