Title: Newton Meters
Post by: miggy on 17 April 2009, 16:41:31

Hope you mechanics out there can help on this one, i am changing the springs on the miggy tomorrow, i notice a torque setting for the spring strut to the steering knuckle reads 90Nm + 45 angle + 15 angle, could someone explain what the + angle means.

obviously tighten to 90 nm
then without torque wrench 45 degree tighten
then 15 degree tighten

think its a stretch bolt thing  :-/

presumably you are supposed to let it 'rest' in between - otherwise it would specify '+ 60 degree'. But how long?

 Yes, as above, let it rest for 2 days. you need to get an angle gauge. Machine Mart do one for about a tenner.

No mention of how long on the TIS 2000, just how to do and torque settings.

you're referring to the mechanic after doing the job aren't you ::)

The reason for the 3-stage tightening is easy .. you do all the bolts in sequence to the torque setting, then the first setting, then to the second setting. This ensures the 2 components are evenly pulled down without any distortion.

Torque settings can be unreliable as many folks incorrectly lubricate the threads, or threads can be dirty, both affect the torque values badly.... so a light torque setting followed by angle tightening is far more accurate.

Oh well, thats put paid to that doing the springs this weekend, tried all over the place in Newport and cannot get an angle guage anwhere, would you belive it.....weather is good also.

How important is it to angle tighten now. :question

You don't have to use an angle gauge. You can easily work 45^o out by "rack o' th'eye" Draw your angles on a piece of paper and use that for reference.
Obviously a gauge makes life a little easier .....  :y

You tried your local Halfords?

make your own gauge with a circle cut out of card- easy :y
