Anyone know the torque pressure of the nut that holds the arm of the steering idler onto the mounting bracket ?. The idler comes in two parts and I've just replaced the arm. ie Female part, nut on bottom of mounting bracket. :-/ Many Ta's.
-
If you're talking about the large nut that has the protective cover on it (at the elbow in effect), then it is 118lbf.ft (160Nm).

There are a couple of torque settings tables on the forum, don't know if they help, but try here (http://www.omegaowners.com/forum/YaBB.pl?num=1161698682) & here (http://www.omegaowners.com/forum/YaBB.pl?num=1156365122).

I take it you mean the steering idler on the pass. side?
Idler to bracket 60 nm
Idler to tie rod 60 nm

Thanks very much for your input lads. Yes I do mean the steering idler, (on the pass:side ).On the drivers side its the steering arm. The nut I'm on about is on the bottom of the idler arm,not the two which bolt the mounting to the chassie member,and not the one that connects the idler to the center tie rod. It might have had a cover originaly but not for a long time. Info is not shown in Technical Info,and not in Haynes either. There was a time when you could phone Vauxhall Tec: Advice Luton, but like so many decent things its gone. Take a look at the Honda website ,theres so much advise and print outs, as it should be. One of my sons has a D reg Prelude and he can still get info on the web.

When it comes to suspension components there is only one torque setting that i use it is the torque setting FT. ;)

Where I used to work one of the lads used the same torque setting for everything:
Tighten till you fart then another quarter turn!! ;) It worked for him!! ;D

In that case mate it will be the one that is at 118lbf.ft (160Nm), does seem a bit high torque, but that appears to be what Vx state, you could always phone you're local Vx workshop and verify.

Its 60Nm....doesn't need to be hugely tight as its a pivot point not a weight bearing item.

The whole assembly though is subject to severe vibration so the torque is required to increase the stiffness of the joint and raise it's natural frequency of resonance. So it doesn't mean that because there is no great deal of weight support that the torque is not required.
You would find that sometimes manufacturing plants use generic values in order to standardise the tooling and save cost.

That one is know as the Steering Arm , links steering box to tie rod.

The data says 60nm so that is what I would use plus a new nylok nut or locktite. Increasing the applied torque on a part where you dont know the material specs etc is not safe.

Thanks for all your suggestions lads. Phoned Vauxhalls, torque value- 41 Ib ft + 75deg + 15deg. [smiley=happy.gif]

:-? Err, thats the values for bolting the idler bracket to the chassis rails. You should know better than ask a vauxhall dealer for any info relating to a vauxhall :(
I thought you asked for the idler arm to mounting bracket and tie rod to idler arm? both are 60nm, and use new nuts.

I guess "Vauxhall Technial Advice " have got it wrong eh? Don't say much for the rest of their cars ,does it? Let me know where you get your advice from, and I'll keep you in mind .

Same source. What usually happens is that you ask a question and they jump on the first bit of info that matches the question, in this case the steering idler fixing values are in one place in the torque tables and the values for the connections to the tie rod etc are further down the list.
If you had asked them "is that for the bolts fixing it to the chassis or for the attachment to the tie rod" it makes them stop and think. Same applies at the parts counter. It has to be said that the info isnt presented in the most user - friendly form which makes their job harder but then you would expect them to be used to it and double check themselves.

How I found out was to ask a workshop foreman whom I know to be very conscientious, ( old school ) with a lot of experience . He didn't know at the time so he checked on the Omega workshop manual (updated), and rang me back, and read it out to me. The two bolts holding the idler to the chassi are as you say 60Nn ie 44lb ft, so is the centre tie rod connection. The nut I'm talking about connects the two parts of the idler together ie the chassi mounting part and the part that joins to the centre bar. (So the nut that connects the two parts together) has a torque value of 41 lb ft, wait awhile ( giving the bush inside time to settle ) then turn the nut 75 deg: wait again, then turn 15 deg:

Thats newer info than I have then so I stand corrected.
