Which impact wrench?

[AHPP]

Does undoing with a torque wrench give you a true reading? Like how you’re meant to be moving when tightening to click to read friction, not stiction. Plus they’ll be rusted on etc. Plus in tension with the wheel.

I won’t undo them Alex, I’ll tighten them.

 

Start low then add 10Nm incrementally until it clicks.

 

Try it with a few then I’ll know.

 

If they were right in the first place….

 

I find it baffling that I can’t find out?

 

Surely the tension in your nuts is fairly important?

This may provide an idea

I reckon 99% of garages just whizz wheel nuts on then clack a clacka for a few seconds. 

 

On a wee skid steer I'd just whizz them on and maybe check them in a couple weeks. Maybe. I mean if the wheels are slopping about it would remind me to check

If it was me I'd whizz everything, then final test/nip with a bar on the socket. I am supposed to be an engineer though.

 

The highest rating you need is able to undo the nuts where they are stuck on, but once you've done it and copper greased the threads that won't be too bad.

Gotcha. Sometimes I'm thicker than I look. You'd still be finding the amount of torque taken to overcome stiction, not friction though. If that distinction does matter.

 

I share your amazement that there aren't easier papertrails for stuff like this. We have the internet. I asked Hyundai about the bolts for my my little chipper. Something fairly small like M8s that hold the blades on the drum. They told me something mad like 165 Nm, which they clearly googled and ripped off the Timberwolf specs that appear at the top of google for 'woodchipper blade bolt torque.' I suspect the bolts would have snapped like blackboard chalk. They gave me a more reasonable number after that, which I use because it's in writing and it's sane but I suspect that was still just derived from a chart.

Had a look at Dewalt and Milwaukee impact wrenches at the APF that were supposedly on offer? A quick Google and they weren’t🤔. Have got mainly Mikita so made sense to get the same, however came across a dewalt one on offer with two batteries in a local dealers that just happened to be cheaper than the makita body only? At least I can now find it quickly on the shelf when required.
