Title: Axle nut size
Post by: spelunker on February 15, 2014, 02:26:13 AM
I have a 2013 S.  What size socket do I need to get for the rear axle nut?

I'm sure you have the manual, so I'll just make clear that it states the torque spec for the rear axle nut (75 ft lb = 20 Nm) but not the size. I haven't tried it myself (haven't needed to adjust the belt yet) but can find out this weekend.

I called Zero.  They said, 27mm.

Just a question why is an American company using metric fasteners?

And that 20 Nm figure is an error.  It should be 102 Nm.  I brought that to Zero's attention as soon as I finished proofreading the owner's manual.   ;)

I think most American manufacturing companies have switched, or are switching, to metric fasteners.  They are a lot easier to buy when you source fasteners from China.   ::)

Because imperial measurements are moronic?

Is that a question or a statement ;D

I still get my feet tangled up.  And I have no idea how to convert F to C, or mpg to liters per 100 km.   ???  It would be nice if we were all on one system of measurements.  But then I would have to learn something new and you know what they say about old dogs.   ::)

I agreed, I just always use google and the search engine just pops out with the conversion.  I always thought for Euro and Japanese they used metric and American and UK?? used imperial.  They should just switch to metric and get it over with!

Seconded!

I worked with bicycle parts and designs for quite a number of years before motorcycles and they were always metric. I got so used to that I started using metric fasteners in anything I design. When I go to get hardware I just always pass the SAE section and head directly for the metric. I find the diameters and thread sizes easier to work with.

When I got my 2010 DS I was upset with Zero's design because everything was metric except the motor mount bolts. I stripped out a couple socket head bolts because I used metric "Allen" wrenches. I had to drill the bolts and take them out with an easy-out. Zero told me, when I complained, that the only way the motor was available was with SAE threaded holes. Many US component manufactures these days will either supply their components with metric mounting only or a choice to the OEM of metric or SAE.

I go with Trikester,

it is easier to use metric and I think the standard thread pitch of metrics is "tighter".

The only pity I see is losing the "feeling" for SAE! I guess you will have a native understanding for fractions - most mechanics "feel" which fraction is bigger because they have their tools in mind - I have to calculate with some of the fractions  :-[
