Hi, Just got the bandit's tyre plugged, but in replacing the brake caliper, the bolts didn't want to torque up (supposed to be 25 lbs/ft). Didn't want to over do it, as they're only softish metal... Is this usual? -- Stonge ====================================================================== AP50, YB100, GSX250, Z400J, CB250, GPz550, FJ1200, GSF600S http://www.brainbashers.com ======================================================================
Don't follow you. Are you saying they are stripped? My SV caliper mounting bolts are spec'ed at 28 ft-lb (39 N-m). Did you use a torque wrench?
Are you saying they are stripped? No (at least I don't think so). Yes - but it didn't trigger it and it just felt wrong as I was tightening, so I stopped turning. Put the spanner back on and they feel tight. 25 lbs/ft isn't far off hand tight with a spanner, so I'll probably leave them alone. Kev
Stonge wrote in sounds like the torque wrench is fucked leave the setting the same and try it on a bolt with a higher setting[1] to see if it triggers before the bolt moves [1] axle?
sounds like the torque wrench is fucked Definitely works... Torqued axle up to 100, and the tested on 25 - worked a treat. Stonge
Ooh, good call. My cheapie clicker wrench sometimes decides it isn't going to click...[1] so I've taken to clamping the square drive in the vise and testing it before doing up bolts. I suppose I should bin it and get a better one. [1] I suspect it happens if I've unwound the spring tension too far, so I've started leaving it set to at least 120 inch-lbs or so.
Be feckin' careful. I've stripped bolts before when tightening them up to the recommended torque. And I've known Haynes manuals get the torque settings wrong.
Hmmm... you're generally supposed to leave them untensioned. It's probably fucked, or at least needs an overhaul and checking the calibration.
That will shag it completely. When the spring is left compressed for any reasonable period of time it will give a lower poundage than shown. DAMHIKIJFK............. /d
Just got the bandit's tyre plugged, but in replacing the brake caliper, the Brake calliper mounting bolts on mine are 27Nm. I had one that wouldn't torque up, the first time that I had the calippers off. You can put so much leverage with a torque wrench - I didn't want to strip the threads - and it felt wrong. I tried the wrench at lower settings. It would click up to about 15Nm, after that it never reached the click point. So I took the bolt out and inspected it. It had been stretching - the centre part of the bolt was thinner than the rest. I reckon that the previous owner had over tightened it at some point. Rather worrying. I replaced all of the mounting bolts.
