Could anyone tell me what Torque settings should I apply for my frpmt wishbones (bolt to chassis brackets) and rea De-Dion (trailing arms to chassis to Tube brackets)

all bolts are high tensile 12mm

you are wrong!

the bush should rotate on the crush tube, not on the bolt. if the bush binds before the crush tube, the tube needs to be longer.

please don't reopen this can of worms - we've had it too many times before.

as for bolt torque, there was a torque list put up a while back. istr about 90Nm for M12 bolts.

Yes, the crush tube should be firmly gripped in the braket and the polybush should rotate on the tube. Hence why the crush tube is longer than the polybushes.

Max tightening torque for an M12 bolt is about 85Nm (EDIT - after seeing Toms post, it seems values differ in various sources!!). Though you will find you might not need it that tight. Its a case of feel (like tightening most fasteners) thats hard to explain, and you learn through experience. Its worth checking all the critical fasteners after a few miles anyway, as things will bed in and they may come loose.

I used the same table and have had no problems, always check after say 500 miles and then regularly.

it's fine with my 19" monitor. get with the times!

it wasn't my pic anyway

and finally, your original statement was ambiguous, and could so very easily start the crush tube debate. AGAIN.

i won't take this any further though

Fine on my old fashioned flat CRT 17" monitor running at 1280x1024 as well.

I am guessing your fancy flat panel only runs at 1152x864 at most?

Its not monitor size that determines how much fits across your screen, its the resolution it runs at.

David

Monitor size is fairly irrelevant, resolution is what makes big things fit in little spaces ;

KY jelly's pretty good too, allegedly . My crush tubes are the same length as my polybushes when they are fitted in the wishbone tube.

Sorry, I'll get my coat before Syd gets here.

you can run a bigger monitor at higher resolution, but still be able to read the text.

tom

Or the same size monitor at a higher resolution to achieve exactly the same, like I say, the size of the monitor is irrelevant.

Thanks for the information

I also need to get some torque settings. The chart is good, but i'll need to translate. So, grade 8.8 metric is the same as sae grade 5, right? And sae grade 8 is metric grade 10.9? So, what is the equiv sae for metric 12.9?


Or, more to the point, what are the torque settings for the various bolts on a cortina front upright?

Thanks, -Scot
