Hi,

Can anyone tell me what the torque values are for the front ARB on a 1990 S2? It's the two nuts on the clamp and also the one at the top of the hanger.

Better still, where are these values documented, so I can look them up myself?

Cheers,
Bryan

I haven't got a 944 but a quick search with our friend google found this if its any help....

Other than that a Haynes manual assuming they do one for the 944?

The Porsche 944 workshop manual is readily available for download and has this and much other useful info. There might be a link in the stickies if not google will find it for you.

Just checked and there is an active link in the sticky - 'READ ME FIRST...' at the top of the thread list. I have successfully downloaded a PDF, so the manuals are still available there.

However, the torque for the anti-roll bar bracket fixings is 23Nm (17 ftlb)

Thanks folks. Now you've pointed me in the right direction, I can see that I should have spotted it myself. D'oh!

I doubt very much that outside of the engine, trans box, suspension etc, that torque settings are not that necessary. Is your spark plugs set to a torque setting? Who does that! Your steering wheel - your wheel nuts? Unlikely too. An ARB bracket is just tightened with a bit of logic grunt...

Fair enough if you're experienced with spanners, but for the inexperienced like me, if gives some reassurance that things have been done properly. Steering wheel is certainly tightened correctly. Don't want that falling off!

disagree somewhat. Wheel nuts should always be torqued up, mine are. I also tend to torque suspension bits as well, steering wheel errr... no. Some of this may be because of my aircraft background & training. Also I find people that don't work on cars frequently or are new to it tend to either under or over tighten fasteners.

my wheels are always torqued too....if your used to working on cars things like spark plugs become common things and you get used to setting them close to torque settings without needing to check....mind you a good mechanic can set most things by hand just by using the correct sized bars and feel...only critical things need a gauge....

I did not used to butI do torque up spark plugs now. I have not snapped a spark plug for years now. You would be surprised how many need helicoiling due to idiots generally overtightening the plugs and that is from a friend of mine who works in the trade. NGK also reckon it can affect plug life as well.

A friend's rocker cover was also scrap after a specialist overtightened his rocker cover bolts. Honda specified 8Nm on the bolts. They were tighter than spark plugs when we removed them (I thought I was going to break a few)!

But yes, some bolts may not be as crucial as others.

"Experienced" mechanics should get their torque wrenches out more often. I have had a wheel come loose because it wasn't torqued up properly. I have been unable to get a wheel off the car, because it wasn't torqued up properly. The cam cover bolts on my S2 were so tight they wouldn't come out without bending and stripping. The cam chain tensioner oil feed was so loose it nearly fell off... the list goes on and on and on... each time from a different "experienced" mechanic.

So yes, my wheel nuts are set with a torque wrench as are my spark plugs. When I changed the steering wheel, I used a torque wrench. Once you've nearly been killed by someone not doing the job properly it focuses your mind somewhat. Torque settings are there for a reason.
