Torque for fork tube bolts
on: October 10, 2019, 03:52:45 AM
Any one with a 2019 service manual I need a question answered-what is the torque for the upper and lower fork tube bolts as they bolt to the fork tree-just need to see if Honda changed the torque for the 2019---thanks

So no one has a 2019 service manual

Apparently not.

However, if the bolt is the same size/length, and it's clamping the triple around the same size diameter tube, you can safely assume the torque is the same as it was before.

Or just nip them up and call it good - the torque is not especially high on these, as it is the clamping surface of the triple clamp that does the work.

Seems all Honda's with a 10mm pinch bolt have a torque value of 24 flbs including the 2013-2018 with the same 10mm bolt-just wanted to make sure-on Rally Raid's site the instructions for the fork kits  have a lower torque figure than the manual-in the old days if we did know the torque of a clamping bolt it was diameter in millimeters times 2.5 in foot pounds so a 10mm bolt would be 25 flbs-very close-the top bolt is a 8mm 2013-2018 has it at 16 flbs my method would be 20 flbs a little off but doable without damage

Most of Honda's bolts from the factory seem on the tight side to me, I've had a few that that felt like they were going to shear when undoing them. I don't usually tighten them that much when doing them back up.

I've just fitted the RR fork kit and just went with the usual 2 white knuckles and a grunt for the top and bottom yoke bolts.

Japes this method, though useful, is totally unscientific as we all have differing degrees of arm and finger strength before our knuckles turn white.  :192:

Well - you only need to calibrate your knuckles with a proper torque wrench. Something like: 1 white knuckle = 20N*m, 2 knuckles = 40N*m and so on  :001:

This was one time that just real tight was not enough- one of the fork tubes slide up-all good now
