ACK!!!!! HELP Rear axel main bolt head size

[Mad Dog]

Changing my rear tire. I saw Freebirds tutorial, which is working great but it says I need a 1-1/6" socket for the rear axel main bolt. So ... thats not a regular thing, and it converts to something like 29.5mm which isn't a real thing either. Since I need to buy this socket can someone please let me know what size it is??

 

Thanks

Hmmmm, been a while!! I sort of remember it being 29mm but don't quote me. The 1 1/16 will work but it is a loose fit. If you decide to buy the metric socket, do yourself a favor and spend just a little more than the single socket and buy a set, then you will have other sizes if and when the need arises...

Sorry...that is a Typo. I will correct it. I think that Bob is correct that 1 1/16 is correct or the metric equivalent would be even better. I know that it torques to 110 ft. lbs. when you are reassembling it.

No problem. The 1-1/16 will convert to 29.5mm so it probably calls for a 29mm. Thanks for the great tutorial, I am following it step by step and it is a great help. Thank you for doing that.

You are welcome but credit actually goes to "Cougar". He originally did the write-up and I just posted it to the tech library.

Your math is off somewhere. 1 1/16 is 26.99mm, close enough to fit the 27mm rear axle bolt.

 

SAE to Metric chart

5/16 = 7.94

3/8 = 9.53

7/16 = 11.11

1/2 = 12.7

9/16 = 14.29

5/8 = 15.88

11/16 = 17.46

3/4 = 19.05

13/16 = 23.81

1 = 25.4

1 1/16 = 26.99

1 1/8 = 28.58

Gray Ghost may be right, and it is a 27mm!! Sorry, I haven't had to torque the rear axle since I converted to trike in '11...

You are correct. I fat fingered something somewhere. Thank you

27mm is the correct size.
