Torque wrenches

After owning many different makes of cars and just doing simple maintenance I have never felt the need to own a torque wrench. I always thought that they were for Real Mechanics - which I am certainly not!

But now as a serious MB owner I feel that I ought to get one, as quite a few of the basic items on my car have designated torque values.

e.g. Spark plugs 28Nm, Oil filter 25Nm, Wheel nuts 110Nm

Surprisingly, not many budget tools in the market span this range - most fit either the top or the bottom end only. I do not want to buy two, but I think that the Sealy AK 624 would just about fit my bill.

Anyone got experience of buying a torque wrench?

You really ought to get two. Torque wrenches work best in the center of their range, not at the extremes which is what you'd be doing in you bought one to try to go from 110nm to 25nm.

Hey, keyhole.

I actually went with two, both click-type, one 3/8" drive for 90% of the stuff and the other 1/2" drive for the bigger stuff. From the old "beam type" days I try to use one that has the settings I need closer to the "bell curve" of the range for the wrench. In other words, the 3/8 is great for those smaller things because it is 5-70 lb/ft (I'm guessing from memory here) and the 1/2 is 25-125. I'm not sure how necessary that is for the more modern wrenches, but back in those days the beam types were not as accurate near the ends of their ranges. In other words, if the beam was 10-100, the indicated 95 might have a 5-10% variance, but at 60 it was dead-on.

In any event, what galled me in buying the two new ones was that the price difference between the two was only a couple of dollars. For some reason I thought the smaller one should be much less expensive.

Side-topic: great tip for the oil filter housing: torque it once, then use white out to mark a line from the cover to the engine. In the future just tighten until those line up. There is a discussion about this in the 210 forum, in the end it's pressure on o-rings, so that on is not so critical as say a lug bolt.

Hope that helps a bit.

Take care and enjoy maintaining the ride,
Greg

Hi guys - many thanks for your replies.

One of the great things about these forums is that it provides the opportunity for us to bounce our initial ideas off those here with more hands-on experience.

I think that the suggestion you both made that these tools would not be very accurate at their range limits was something that I had not considered, but it makes sense.

The Sealy AK 624 range of 28-210 Nm will do for the wheels. I will find another to cover the lower torques.

Ref Greg's tip about marking the oil filter housing before removing it - I had already picked that up on the 210 forum and will use it. We call that stuff Tippex over here.
