Exclamation Torque Wrench Needed - December 12, 2008, 01:43 PM

Some of you might have seen my clutch thread "CLUTCH Question" and I will be getting my new clutch in the mail early next week as well as a new clutch cable.

The clutch kit includes the new clutch springs and they need to be torqued to 5.8 ftlbs, I only have a torque wrench that goes as low as 20 ftlbs.

Does anyone have a torque wrench I can borrow for a day or two? It can be in ftlbs (as long as it goes to about 5 or 6 ftlbs) or it can be in inchpounds (and I'll just convert it). I'm in Reston VA, thanks in advance

You really don't need a torque wrench for that. That's just a hair past finger tight.
Think of it this way, if your wrench is 6in long apply ~10-12lbs of pressure on the end 12in=5.8lbs, 18in=2.9lbs. Surely you have something around the house that will match up with the length of your wrench. See what that amount of torque feels like and learn to calibrate your hand/wrist/arm for torquing bolts.

I'm dead on when I check myself with a torque wrench.

thats what a friend of mine told me as well...."that its just a little past finger tight"

I just thought I'd ask before the install...I'll take your advice into account, thanks SV

6in/12=0.5 feet
0.5ft(12lbs)=6 ft-lbs

just hang a 12 lb weight at the end of a 6in wrench. 12 lbs is about the weight of 16-12 ounce beers, so we'll buy a case, drink 8 of them, hang the remainder of the case off your 6 inch wrench and then drink the rest.

so every half foot of tightening rotation past hand tight = 6 ft lbs of torque? is that regardless of bolt / screw / nut head size? or do you just hang the required # of beers on the end and spin the wrench lol

The amount of applied torque is dependent on 2 things. The length of the wrench and the amount of weight or force that you put at the end of the wrench. It is not dependent on the size of the nut head. Torque = length x force (hence ft-lbs).

In Spykers case he needs to apply ~6 ft-lbs of torque to a nut. He will first hand tighten the nut just until he feels some resistance. Then if the only wrench he has that will fit that nut is 6 inches (0.5 feet) long then he will need to apply 12 lbs of force to the very end of the wrench (0.5 feet x 12 lbs = 6 ft-lbs). In the case of hanging beers off the end of the wrench he will need to position the wrench on the nut so that the wrench is just above parallel to the ground, then hang the beers off the wrench and allow the wrench to rotate. He will repeat this process until the wrench doesnt rotate anymore. Finally he will finish the remaining beers in the case with dv/dt. (This is all assuming that he is tightening a bolt that is positioned parallel to the ground)

Please take pics of the beers hanging from the wrench!
I have one if you want to borrow it. I am in Frederick but would meet you someone half way!
Of course during the week I work in Beltsille so on the way home I could meet somewhere also.
