Title: Torque Wrench or just guess?
Post by: MoToFaLcon on August 16, 2014, 08:54:14 PM
Thinking about getting a craftsman 3/8 in. Dr. Digi Click torque wrench. But wanted to know if its really THAT important? Couldnt it be possible to just use common sense when torquing large and small nuts and bolt and never have any problems ever, as a result?  What do u guys think??

Depends on your experience and how many bolts you have broken and how many holes you have stripped out! Forget the torque wrench if you have that invaluable experience. Use that "feel" which is the common sense. Use the Digikey wrench if you are just startin' out.

I have two beam type torque wrenches, one in inch pounds, the other in foot pounds. They are necessary when you are building an engine, for say like the head bolts. But for everything else, the are not used too often. Once you get a feel for it, you don't need them much. But they are good to start out with especially for when you have a steel bolt going into aluminum,like an oil drain plug.

I got 2 Habor Freight TW's $21 a piece: a 1/2" drive and 1/4" inch drive that seem to get the job done. 1/4" over 3/8" because cheaper quality TW's have their best accuracy in the middle range as what I've read. Also set them to zero when not in use to take tension off the spring. I've snapped one too many bolt and striped one to many threads on this scooter.

Yeah like Chris said get a 1\4" if anything, I've found the larger ones are too big for lots of places on s scooter and you hardly need to torque that high. And I only use a torque wrench for head nuts and case bolts. Everything else is impact or feel (not a guess!!!).

I have an old friend that uses one on everything including his lug nuts. I've changed many flat tires and never ever had a problem going by feel.

If I came across one and was doing some major work I'd use one for sure (as mentioned above) but for everyday things I don't think it's needed in the least, common sense.

Yeah, Blue! You guys ever hear about "white knuckle, red face tight?" Harley old time mechanics used "white knuckle" for low torque, "red face" for medium and "white knuckle AND red face" for really high torque! All cast iron, stove bolt Harleys were like that. Not any more! Too much alloy these days......

use impact wrenches to tighten variator and clutch nuts and have always done it this way.
Some time back I watched a video of a Vespa mechanic servicing a Vespa. Variator, belt, clutch etc..
He stressed that it was important to properly torque the variator nut because if not properly torqued , it could cause engine damage. Think it had something to do with the pump chain.
Think I saw the video on Modern Vespa.
Anyhow, torque wrenches are not very expensive so when I service mine i'm planning on torquing to spec..

I started to use that on almost everything after I stripped the gear oil filler bolt.
