DodgyRog Posted March 27, 2011 Share Posted March 27, 2011 As above, going to do a home refurb on my Work Split rims, I intend to take the bolts out and remove the centres, then strip and spray them Before I take them apart, does anyone know if there is a Torque setting for the bolts, when I put them back together I am planing this to be a tempory tidy up until I can get the cash together to get them done in Black Chrome by Ibrar at Speedwells, I just need to tidy them up a bit, as they are letting the car down and I am fed up of seeing the paint flaking off:rolleyes: Quote Link to comment Share on other sites More sharing options...
sideexitsupra Posted March 27, 2011 Share Posted March 27, 2011 90 NM or 70 foot pounds should do it. Quote Link to comment Share on other sites More sharing options...
nasoup Posted March 27, 2011 Share Posted March 27, 2011 Do you know what thread size the bolts are? Quote Link to comment Share on other sites More sharing options...
Dnk Posted March 27, 2011 Share Posted March 27, 2011 90 NM or 70 foot pounds should do it. On my Work Equips their M7 x 1 mm and your looking at around 20ft lbs, use a dab of thread lock when you torque them back up Quote Link to comment Share on other sites More sharing options...
DodgyRog Posted March 27, 2011 Author Share Posted March 27, 2011 90 NM or 70 foot pounds should do it. That sounds like way to much to me, but where did you get the figures from Do you know what thread size the bolts are? Don't know yet, I have not checked, how do I check:blink: On my Work Equips their M7 x 1 mm and your looking at around 20ft lbs, use a dab of thread lock when you torque them back up That sounds more like the sort of figure I was expecting, I would of thought Work would of used the same bolt in all there wheels Quote Link to comment Share on other sites More sharing options...
Digsy Posted March 27, 2011 Share Posted March 27, 2011 Do NOT do them up to 90Nm. FFS where the hell did that figure come from? On my BBS split rims the perimeter screws were M7x1 and I did them up to 35Nm and part of me thought that was pushing it. Use a dab of Loctite 242 or 243 as well.

Scott Posted March 27, 2011 Share Posted March 27, 2011 I'm guessing the 90 was plucked out of the sky Quote Link to comment Share on other sites More sharing options...
sideexitsupra Posted March 27, 2011 Share Posted March 27, 2011 Not plucked from the sky. From experience with circuit cars. Each to their own. Have never used threadlock on a wheel. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted March 28, 2011 Share Posted March 28, 2011 20 ft lbs is plenty tight enough for bolts that size. I'd use 18 myself. Quote Link to comment Share on other sites More sharing options...
Scott Posted March 28, 2011 Share Posted March 28, 2011 20 ft lbs is plenty tight enough for bolts that size. I'd use 18 myself. 7mm should be good for over 100lb surely? I take it they are stainless? Quote Link to comment Share on other sites More sharing options...
Digsy Posted March 28, 2011 Share Posted March 28, 2011 I'm going to reduce my figure to 25Nm. I'm still 99% sure I did mine up to 35Nm but I just re-did the calculation and it came out much lower and I can't think what I would have changed. A "normal" torque for an M8x1.25 is about 28Nm and for an M6x1 its more like 10Nm so an M7x1 should be somewhere between the two. I've assuemd that the bolts are stainless steel going into aluminium.

You know these are the rim bolts we are talking about? Not the hub bolts. Quote Link to comment Share on other sites More sharing options...
Dnk Posted March 28, 2011 Share Posted March 28, 2011 You know these are the rim bolts we are talking about? Not the hub bolts. I was thinking exactly the same The torque on the rim bolts will vary due to material spec, diameter, pitch and if you use a thread lock or not. Also if there a nut and bolt set up like mine or bolt into the aluminium center piece. There is no way on gods earth you should be tightening these up to 70ft lbs Quote Link to comment Share on other sites More sharing options...
jagman Posted March 28, 2011 Share Posted March 28, 2011 in AF but metric would be similar (these are standard bolts ie highest quality) Halfords,made in china bolts ,from some sort of cheese derivative .....this does not apply !!!!

Not so sure the alloy of the wheel would though Are split rim bolts that big? I didn't realise they were that size. Quote Link to comment Share on other sites More sharing options...
Dnk Posted March 28, 2011 Share Posted March 28, 2011 Just google split rim torque settings or something similar and you wont find anyone listing such high figures, BBS are 22/24 ft lbs Quote Link to comment Share on other sites More sharing options...
Scott Posted March 28, 2011 Share Posted March 28, 2011 Just google split rim torque settings or something similar and you wont find anyone listing such high figures, BBS are 22/24 ft lbs Oh I didn't think for a second they would be, I was just referring to what a 7mm bolt could actually take and why people shouldn't worry so much about it falling to bits Quote Link to comment Share on other sites More sharing options...
Digsy Posted March 28, 2011 Share Posted March 28, 2011 Jagman's figures are in LB inches, not foot pounds. 107 LBin = 8.9 LBF = 12Nm Quote Link to comment Share on other sites More sharing options...
jagman Posted March 28, 2011 Share Posted March 28, 2011 Also "Standard" bolts Once upon a time when Britain ruled the world , lol, "Standard" was the finest quality , so a "Standard" instrument for example was an instrument that was used to calibrate others by, in a standard calibration room , all other instruments were then "sub standard" or lower catagories over time such terms were lost , who would buy something sub standard now? ... and we went all metric and loads of EU numbers that no one actually knows , and then made in china ...

I don't think we go into feet until after 10mm. I would need to check the torque wrenches though. But yeah, don't go trying 100lbs feet Quote Link to comment Share on other sites More sharing options...

Fortunately enough of you spotted my error before the OP acted. Must read things twice, must read things twice, ..........................
