				Torque Wrench
			 
			What kind of torque wrench is needed for basic maintenance on a 911. Harbor Freight has them for around $20.00, is that adequate? Also, what is the most commonly used size? Do I need to get a 1/4", 3/8", and 1/2" Thanks, Jon

			I think the first one would be the bigest one, 1/2", to torque your wheel lugs/nuts. Then the next one would be the 1/4", smallest you can get, for your valves cover nuts; which I don't have yet. I wish I can get something smaller than the one at HF. I also have some in between, which I rarely use.

			+1 on getting a 1/4in and a 1/2in.  I have a 1/4 and 3/8in from HF.  They work fine.  I only use the 3/8in for torquing my oil drain plug, headstuds, and fan nut.  My 1/2in drive is my dad's, which is some other brand.  The 1/4in from HF is big for a 1/4in, but in/lb measurments are handy for things like the alternator strap and oil level sending unit.  With some good small 1/4in drive torque wrenches costing above $100, the HF is a good compromise for most general stuff.

			Like rnln says, I also have 2: 1/2 in for the heavier stuff like wheel lugnuts, and a 3/8 in for most other things.  I have Craftsman, myself.  I've had them for about 10 years.  There are better (more expensive) ones.  There are cheaper (?less reliable/durable?) ones.  The inexpensive ones often can't be rebuilt/repaired.  Course, they're cheap so you just throw them out and buy another.

			a torque wrench is not just a wrench; it is a precision instrument I would never use a cheapo Harbor Freight one on my car - esp. on the wheels which could easily kill you if too loose but there is no need to get a 1/4" one for the valve covers - just make them snug - search up the thread active in the last 2 weeks on this; I think Peter Z. posted, not sure search up the numerous threads on torque wrenches for much much more info Bottom Line: get a good 1/2" one for the lug nuts; get 3/8 for engine or trans. rebuilds, and test them periodically for accuracy Craftsman used to be fine; no idea nowadays | ||

			talking about perfect torque, it is recommended to check/calibrate every month or so. I use to write documents for a limo manufacture years ago. They have all good/expensive torque wrenches and they can't skip this rule. I went through several torque wrench and still get the HF because I figure for this price range, if it go bad, just get another one. Later, I realized that they went bad because it was my fault, didn't release them after each use. The last set I have (cheapo HF) lasted me years. Periodically, I checked them with a friend of mine. Can't remember what his was, but not HF.

			+1 on Grady's post. Multiple torque wrenches are needed depending on the application and torque requirement. Torque wrenches are most accurrate at +/- 60% of the respective wrench mean value. I.e, if you have a troque wrench rated for 25-100 ft lbs; it is most accurate +/- 60% of the midpoint (62.5 ft lbs) Personally speaking, I would not use a HF torque wrench for any critical engine assy. My experience and training are in aircraft / aerospace applications. Earthbound applications can and should be less stringent. Some of the better torque wrenches are Snapon, Matco, Proto...Before I tossed away money on a HF torque wrench, I'd look for a good quality used wrench on craigslist or fleabay, and have them calibrated/certified at a local calibration shop.

			I buy things like, gloves (for example) at HF. For precision tools I might buy new or used if it looks like it's a legit buy on eBay. I realize it's tough to know when buying used online. That said...I have a Mac that goes up to 150 lbs that I bought for $200 used and it looks like new. It is a beautiful tool that feels much different than a lesser quality tool. If funds are limited and you have to save bigger spending for the car, that's understandable. Been there and done that too.

			Interesting thread: Is a Harbor Freight Torque Wrench Really Bad? Personally, I own both a 1/2" HF and Craftman clicker type plus a 1/2" Craftsman beam type unit. Periodically, I check them against each other. So far they agree well enough to make me happy.

			I recommend torque wrenches from CDI Torque (CDI Torque Products, America's Largest Manufacturer of Torque Equipment).  The company is owned by Snap On and they make a quality product at a very reasonable price.  You can purchase them from Amazon at a very good price. I have a selection of CDI Torque and Hazet (love me some German tools) torque wrenches.  You won't be disappointed.  As the other poster mentioned, torque wrenches are a precision instrument and as such you should invest accordingly. Regards, Chuck | ||

 I'd suggest he gets a 20 to 100 lbf.ft. 3/8 ich drive unit made by Precision Instruments who I believe make them for Snap-On. Its a flex head ratchet click type. After that one, a 1/4" drive unit that takes care of all torques below that one. Personally, I own three that cover from 3.5 to 250 lbf.ft....they're also calibrated.   | ||

			My 3 Snap-On torque wrenches have worked for me for 25 years without needing to be re-calibrated due to proper care and use. I have checked them regularly, and they are still 100%accurate. They will last longer than I will.... Quality and accuracy in precision tools, you get what you pay for....

			Like Traveller, I prefer the Precision Instruments split-beam torque wrenches.... I have the C2FR100F and the C3FR250F. I like the flex heads. These are the same as the Snap-On torque wrenches that look like them. Just cheaper..... Scott | ||

 I bought my first one in 1975. It wasn't till I had the chance to personally calibrate it in our labs in 1992 that I knew how accurate and precise it was. Of course proper use and storage make a big difference. In fact it was good over the full 5 to 75 lbf.ft. range and repeatability was incredible (I took 5 readings at every 5 lbf.ft over the full range). Repeatability is the most important factor. I don't care if I have to dial in 52 to get 48 as long as I get 48 every time I dial in 52...that is called repeatability and time enters into that as well. A good wrench stays in calibration. | ||

I don't actually own that brand. I just recommend them since they are the same as those from Snap-On, just a bit cheaper.
