R1150RT Replacement of Front Shock

[wrchunter]

I tried to torque the top nut on a replacement aftermarket shock to the torque specification...but the piston of the shock started rotating before I could get to the 43 Newton torque spec. I don't know what to do next. Any help would be greatly appreciated.

If I'm not mistaken there is a flat spot on the top the shaft (above the nut). Use a wrench to hold shock from spinning.

Welcome to the forum! Let us know how you make out...your info could help the next person!

There should be either provision for a wrench (flat spots) or allen key at the top of the threaded shaft.
Tighten the nut tight securely while holding.
I don't worry about torquing exactly to spec. (43nm) but you can always use a crows foot if you insist.

And yes, welcome to the forum!

"Across the flats" at the top of the shaft is small enough that any wrench I have would flex instead of hold, so I've used a small bench vise (not mounted on anything) snugged down on it and held in one hand while I tightened the nut. Works great. Torqued to one medium grunt (about what it took to remove it the first time).

Flat faced vice grips.

Thanks for the response

The shock didn't have a flat spot to hold, but I just bit the bullet and put some channel locks on the piston and torqued the upper nut to spec. It worked with only a slight scratch.

Thanks again.

What brand/model shock did you install - that didn't have flats or a socket for an allen wrench? I want to know what to avoid.
