HF has a great electronic strain gauge based digital torque adapter, intended for using any 1/2" drive setup as a torque wrench--however after dead weight testing and finding it to be very accurate (withn ∓0.5%) I now keep it as my "in-house" calibration standard. I clamp it in a vise (using cheap 1/2" to 3/4" adapter in the vise) and use it to check (and calibrate if needed) my wrenches periodically and before any critical application.This is neither here nor there, but in reassembling the pump on the engine, I learned the hard way that my cheap and seldom-used torque wrench may be on the fritz. I was thinking, hmm, I've been turning this wrench for kind of a long time...and then the upper left-hand bolt broke in half. See photos (in the first one, there's supposed to be a bolt head sticking out of that hole behind the belt). I should have the stub drilled out ASAP and get a replacement bolt (and torque wrench), correct?
P.S. As you can see, I put the pulley and belt back on anyway, and when I started it up, all systems seemed to be go. I'll optimistically consider it a job mostly done.
