Last Time I Use A Torque Wrench! .......Update......

[fozzym]

Bloody nora

I've only gone and broken the bottom yoke when I was doing up the clamp bolts.....using a flippin torque wrench!
I don't often use a torque wrench but thought that as the forks staying in the yokes is fairly safety critical I'd do the bolts up to the book specs 20nm.

I've had the forks out to do the seals. Popped the left fork in and nipped the bolts up then torqued them, smashing no probs. Did the same on the right side and crack, the clamp bit literally sheared.

Bloody Hell

Oh well I've managed to pick up a bottom yoke ass on ebay for 18 quid so not too bad. I'm more pissed because I wanted to get the bike back together today.

Balls to using a torque wrench in the future!

What do you need a torque wrench for. Two grunts and a groan is always right.

Snap on wrench, as used in my father inlaws prof garage so in tip top condition.

I think the yoke was probably fooked so yes better it failed today than the next time I popped the front wheel up!

I've snapped bolts with a torque wrench on low settings - 15nm if I remember correctly.
Bolts were made of cheese and didn't feel tight at all. Just went 'pink' and the heads came off.

I'd suggest there was something horribly wrong with your bottom yoke if the clamp split without both hands on the wrench and the veins popping out on your forehead.

I'd fully expect either the thread to strip or the bolt to snap before the clamp itself let go.

There was almost certainly a flaw or hairline crack in the casting, either from new or from a frontal impact at some point in the past.

Lucky it didn't happen while you were riding it really.

even a snap on needs to be calibrated now and then

Couple of photos.

[yampug]

maybe it was a defect in the casting?

i would have thought the bolts would strip first on most yokes before the yoke cracks.

has the bike ever been in an accident?

Torque wrenches shouldn't be used with extensions either. Think of it like this, try undoing a screw with a stubby screwdriver and then the same one with a much longer screwdriver, which is easiest?

Torque wrench - why? You always know when something is tight enough. It comes with practice. Have got a pretty reasonable Clarke one but haven't used it in years. Not necessary. With a ratchet or spanner it becomes obvious when a nut/bolt is just right.

I've lost track of the number of times that I've recommended using a deflecting beam torque wrench as an assistance to Mk 1 Mechanical Sympathy.

It looks like there were some old cracks in the casting although the majority is fresh, I have highlighted them but would need to look under a microscope to be sure.
