Tried torquing head bolts with a beam wrench instead of my click type
I was doing an injector swap on a C15 Cat last week and grabbed my old beam torque wrench by accident. Figured I'd just use it anyway since my click type was acting flaky. Got all 6 injector hold-down bolts torqued to spec but when I double-checked with a different click wrench, three were about 3 ft-lbs low. Learned that beam wrenches are fine for rough stuff but I need something more precise for injector work. Anyone else had weird results switching between different torque wrench types?

Nah, I'm gonna push back on this a bit. A beam wrench is literally measuring the same physics as a click type, just showing you the deflection directly instead of hiding it inside a spring mechanism. If your beam was reading 3 low, sounds more like your technique or maybe the wrench itself needed calibration, not that beam wrenches are inherently less accurate. I've seen guys use beams for decades on critical stuff and never had issues as long as they read it at eye level and don't jerk it.
