Craftsman torque wrench

Fair warning, this might be one of those things that only bugs me. Okay, I noticed that most of the torque specs for a Jap bike are kinda weird numbers when given in ft/lbs. This is of course because they are converted from normal numbers given in Newton/meters. We work in metric all the time with these bikes, and it's loads easier than keeping track of 11/64ths and silly numbers like that.

So, I look up a torque spec in my manual and they graciously include the metric (easier) equivalent ( say 50 N/m just for grins) I look at the back of my Craftsman torque wrench, and the numb-sculls have engraved the settings as conversions from the standard side at the same increments. So you end up with no 50 N/m, but an often used 47.69 N/m instead. I realize you can guestimate the proper setting , and these $70 wrenches are certainly not calibrated by those 5 secretive Swiss guys that run the world, but what kind of retard is paid to design these things and thinks this is the way a tool should be?

Uh, rant mode off..

I LOVE harbor Freight!!!
But I also love Craftsman stuff too, so go figger.

There's no reason that the metric side wasn't scribed and marked for even #'s that I can figure out.

50 N/m?!? Wow! That's, like what? over 300 ft/lbs?

My wrench (a no-name brand) has as the following for size on the metric side of things:
(daN.m)
M. KGS.

I don't know about the (daN.m) over the M. KGS stands for, but the M equates to Foot on the english side and the KGS equates to the pounds on the english side.
So, is M/KGS the same as N/m?

well the 50 N/m thing was just hypothetical. except of course on those little nuts that hold the front axle clamp on.

Colorado Mike, it sounds like you are almost aggravated enough to buy a Newton - meters torque wrench. :grin:

skipro3, the wrench he is talking about is a Sears Craftsman Microtork (the used to be $70, now $75 torque wrenches they offer). I have two of them. It is set by turning the handle a certain number of clicks to get to the proper torque setting. He is using a foot - pounds torque wrench, so it advances a certain amount of foot - pounds with each turn of the handle. Since the foot -pounds and Newton - meters scales (or Kg - meters scales for that matter) do not match up, the fractional N/m equivalent is listed.

Kg - m is not the same as foot - pounds or Newton - meters. Where have you heard Kg - meters before???? Suspension springs! :grin:

Also, metric is Kg - meters or for the little stuff Kg - centimeters.

Sears has three N/m wrenches listed in the catalog, $160, $180 and $200. If those won't do, there is always Snap - On, starting at a little over $200 each. I am just thankful to have my "I hope this is close" Sears Microtork wrenches.

To all: Don't forget to loosen the tension when you are finished!
