Dog Bone Mount Fitted but Some Advice Please

[edmong]

Hi Guy's,

I fitted my Powerlex DBM today but I think I have made a boo boo!

I have torqued the 'clamp' bolt to 40Nm, which I think is too much as the vibrations through the car are bad, liveable maybe, but bad!

The good thing is that the traction is a 125% better!

What I need an answer for is the correct torque setting for the clamp and if loosening it by a great deal will ruin the traction I now have. Hopefully there will be a happy median.

Remember its the clamp torque amount none of the others.

Do not worry kind sir, these vibrations will subside over 300-800 miles isssshh!

I had the same problem and i cant tell iv got mine now!!

The settings vary depending on the mount, but i used these http://www.seatcupra.net/index.php?option=com_content&task=view&id=503&Itemid=6


Hope that helps

Thanks for the reply but the link does not show the torque setting for the clamp and thats what I am after. Whats yours too?

Mines the powerflex one dude,

This is the guide i used http://www.neuspeed.com/data/installs/22.10.89.pdf

Recommends around the 20ft-lb of torque

so 27Nm approx.

40Nm is high then

Just see if it dies down, i think my vibration was a visible steering wheel wibble, and a low freq hum with some transferring into the seat!!

All only on tickover

wouldnt worry to much about the torque setting as the vibrations will stop after a few miles of bedding in. they will slowly go away

Worth getting a decent rubber one if you can instead as it doesn't suffer from this...

 

[Jimski]

This is the whole point of them though, the stiffer the better? More traction, less wheel spin, i couldnt believe the difference it made, once you've done some miles, you wont even tell you've got it on.

OEM mounts are made of playdoh compared to these babies, and for £15 they are pretty evenly priced i think!!

Yes, stiffer is definately better - but poly bushes are not really very good as they transmit harsh vibrations. A very stiff rubber mount will have all the good properties you are after (reduced movement) but without transmitting the vibrations. Poly bushes are really just a cheap way of stiffening up bushes but they are quite crude. I'd prefer to pay a little more for some good quality rubber. Take a look in the INA thread they're very good products.

I set my idle to 800rpm to get rid of the vibration on stand still and as the others said it will settle down, eventually!

Thanks for your replies.

I dont want to start a war on the 'VIBRATIONS' so i'll put this thread to bed now.

All i wanted to know what the correct torque setting was for the 'clamp', which now I know is 20Nm.
