Torque wrench range?


Recommended Posts

What is a good range for a torque wrench? Have been looking at the Precision Instrument ones.

 

Would 20-100 lbs ft be a good range? 

 

It seems to cover most "important" engine related, lug nuts, suspension components?

 

Some less important things like oil pan covers, chain guides seems to be below 20 ft-lb. But I guess a good "feel" or over tighten might work there?

 

Seems like there are some delicate engine parts that requires less torque, things like camshaft towers?

Really depends on your car... E30 has lots of fasteners that are >100 ft lbs.

 

This is my go to wrench.  Buy one and be done.

E30 has one VERY important fastener that exceeds this wrench's capacity.... so I had to buy another, larger tool, but other than that...

Definitely a nice torque wrench. For those looking to spend less for nearly all the same features my buddy picked one of these up; https://www.lowes.com/pd/Kobalt-1-2-in-Drive-Programmable-Electronic-12-ft-lb-to-250-ft-lb-Torque-Wrench/1000248545

 

It's nice quite as nice as the snap-on. But for someone not making their living turning wrenches I think it's an appropriate substitute. They also have it in 3/8".

 

Also for shade tree mechanics the crank bolt can be tightened using math, a lever arm, and a bathroom scale.....:ph34r:

So what about micrometer vs split beam?

This is the one I went with, and I have been happy with it. Split beam does not need to be relaxed back to zero pre-load between uses.

Head bolts are the only thing that I torque, everything else is just yep......that feels about right, or 5 seconds of air impact for stuff like axle nuts. 

 

20 - 100 ft-lb sounds like the right range to me. 

We have found that our wheel bearing life is directly related to axle nut torque. There was a redesign in axle nut that only called for 150 lbs. The nuts would always come loose. Found the originals and went with the recommended 235 lbs and haven’t had a bearing failure since.

Got that one, $125 after tax.
