B230 sump plug torque

bluesntwos · Apr 5th, 2019, 14:07

I've looked high and low for the torque figure for the sump plug bolt on B230 (1995 940). The only figure I could find was as below;

The Bentley book for B230 recommends a 1" socket and a torque setting of 60 Nm (44 ft-lb).

I just wondered if anyone could confirm this. The last thing I want to do is strip any threads!

Thanks.

Yes that is correct :-)

I have always thought 44 ft lb seemed a bit excessive particularly since torque settings are usually quoted using dry threads and it is impossible to dry the sump drain thread. Personally, I usually use 22 - 25 ft lb on oiled threads and have never had any problems; but obviously you don’t want to risk the sump plug working loose.

I've usually gone for a similar approach to spark plugs, nip it up then 1/3 - 1/4 turn more, don't think i've ever used a torque wrench on a sump plug.

You need the plug tight enough to compress the new every time copper washer (gasket) so that you do not get oil leaks from the plug. I find the recommended torque does that fo me on a B200.

I do it to about 55 Nm. Wouldn't feel comfortable torquing it only half way.

About 5 seconds on a half inch impact gun should do it..

When I was fitting my suspension balljoint I asked Colin, a very experienced mechanic, how much torque.

He made a motion with his arms, saying "gnnnnnrgh ... that much"

I think similar is required with the sump plug.

I think the correct internet torque ratings are measured in "ugah ugah's" as provided by air guns.
