Good (tire shop) words to live by!
And more.....
TORQUE WRENCHES 101:1. For pickups, TTs & 5th Wheels.
Harbor Freight - good deal (for the price), but short length.
Xln't to toss in your RV compt and forget it.
For home use - the Husky brand from Home Depot (under $100) - is 26" long, with a limited lifetime warranty. Max TQ is 250 ft lbs.
The Harbor Freight breaker bar (or similar) is "OK" - however the pin holding the head can break (had that happen before)..:(
A better choice is a 3/4 "sliding head T-bar" type.
(No pin to break!).
Unless *designed* to remove lugs (etc.), these types of TQ wrenches should *not* be used as a breaker bar or used with a "cheater" for that purpose..:(
Also, always "zero it out" when done, and it's good idea to check your wrench from time-to-time.
See YouTube for lots of "How To": Enter - "Torque Wrench Calibration".

2. Motor Homes & MDT/HDT - "serious" TQ necessary!
A TQ wrench - like Mod Barney is holding - will run about $200-300 - or more.
The 3/4 drive "Klutch" brand in your 2016 Spring Northern Tool Catalog (pg. 432) is $250., and with a 4:5:1 planetary gear ratio, delivers low torque (488 ft lbs) to high torque of 2200 ft pounds.
Performance Tool brand (same page), range 100-600 ft lbs is $300.
Also see Proto tools etc., for "pro" type TQ multipliers = lots more dollars - and no need to have the monster Barney is holding.
Back to "Tvov" - the OP's question....
Nice "cheap-O" multiplier info and "tutorial" w/pics here..
DIY *HDT* Tire Changing MethodAnother Torque Multiplier thread...
*here*.
The inexpensive multiplier (Northern Tool) linked in the first post is no longer available, but it was similar to what Tvov referenced and avail on lots of internet sources.
Happy CQ-ing - oops, edit! - That's Ham lingo, I mean "TQ-ing"..:C
