Technical Front bolt on cross member

[airwave]

Hi guy's , quick question here .

I'm sure it's being asked many times in the past , but i'm pretty new on forum , and can't find the search function .

I'm in the middle of some quite major work on my 2000 , 2.8 duke . It was during this work i discovered some minor corrosion to the front off side chassis , just above where the front cross member bolts . Already having the radiator out , i dropped the cross member to make access for the repairs better . I also ended up giving it a harsh power sanding , and repaint .
Now the repair is complete , i'm ready to replace the cross member , but i can't find any information regarding the torque setting ! .

Anyone else know ?

The search tab is located on the green bar, towards the top of the page. Scroll up as necessary to view.

Attached eLearn pdf of various torque settings for front suspension, which is the nearest that I could find.

Given the quoted ranges, the settings are obviously not ctitical.


I suggest selecting the appropriate diameter, and selecting a round Nm value (table x 10) mid range value. If you have greased the bolts, go below the mean value.

My largest torque wrench has a maximum setting of 250 Nm, but I cannot remember what I used when I had the bolts out for preventative greasing.

If you have not tied the chassis together, it may have spread. A heavy duty webbing strap may help if this has happened.

Thanks for that my friend , actually i had already found that particular table , and yes suspension is the closest i could find , myself . There is a cross member listed under body , but the torque setting was extremely low at 21 nm .

It's interesting the values are so low , for such major components . Even more so with the fact , that i will be fitting an A frame type nudge bar , with one setting of 50 nm . To be honest , i've still not torqued them up yet . I decided to remove one bolt to check it's size and use a standard setting . I believe these bolts to be around m10 - m12 , so i'll probably go for some thing between 27-35 nm .
It would appear i was lucky , the chassis had not spread , and that's despite the strut being removed for nearly 8 months . I would not have considered this a possibility due to the proximity of the engine mounts , and front subframe , so thanks for the heads up , despite it being late . Mind you , i can add the vehicle in question is a non runner , due to the cooling system being compromised , and battery(s) removed . It never moved with the strut removed anyway . Wiring , timing , breathing and charging circuits were also compromised , some more than others , i did say quite major work . This vehicle is 20 years old , and though only 47000 miles , is a typical motorhome , and not had any regular maintenance , probably since it was 3 years old .
