Mirror bolt torque?

[bduffey]

I'm replacing the mirror extenders on my bike and in reading the instructions, I noticed that the manufacturer calls for 46 ft lbs of torque on the replacement bolt that goes into the mirror attachment on the brake resevoir.

While I normally don't use torque (as opposed to 'guesstimating' the tightness) 46 nm seems high. This spec sound correct?

Ft/lb at 46 or Nm (newton/meter) at 46?

Either sounds too high to me.

Could they have meant inch/pounds?

Probably 4,6 ? I can't imagine 46 is ok ?

Could be a typo on the sheet. The directions are mostly in German. Sketchy at best. I'm sure I'll just use the old 'tighten then snug it' method.

Mirror bolts need to be fairly tight as otherwise they will come loose. However I agree with others on here that 46 Lb Ft is too much.

don't forget to add some threadlocker. red is probably too much,but blue might be just right

So I gave the directions sheet from SW-Motech to my mechanic while at the dealers this a.m. He read the thing twice and agreed with me that it said 46 nm. So whether the manufacturer meant ft lbs or inch lbs, the direction are way off-base. At least I know that I wasn't imagining things. Back to the old tighten then snug method.

Ditto.
