Tightening a camshaft sprocket bolt and no room to get the torque wrench on it directly. It calls for 66 lb. ft. The distance from the center of the box end wrench to the square drive of the cheater bar is 18 inches. What do I set the torque wrench to?

When at 90 degrees, there is no modification. When "A" is negative... you have to have a higher indicated torque on the wrench.

Make sure the bolt isn't a torque to yield bolt if your reusing it. If the vehicle is European, there's a good chance it is.

Thanks. Also found this http://www.fordservicecontent.com/renderers/torquewrench/wrench_formula_main_en.asp

Wouldn't a torque to yield bolt have a + angle to it? There is no mention of replacement in the repair manual.

Total Wild Guess. 44 should be plenty 18 is 3/2 of 12 and 44 is 2/3 of 66. Never used a torque spec when tightening a sprocket bolt . hide

Yeah this. You can get a little ratchet with 3/8" or 1/2" drive in-and-out if the setup you have won't give you 90.

OT That cheater bar looks neet.

so you would take the org length of the torque wrench (L)

find the total length the wrench and cheater bar (A)

and then divide [L /(L+A)] x required torque(66)
Which in this case I think you would end up at about half or 33lb-ft


example numbers if the torque wrench is 16" and the cheater/wrench combo is 18"

you would take 16/(16+18) or .47 x 66 =31

Me too!

Far more elegant (and likely to fit) than my current cheater pipe (an old jack handle).

It's called a wrench extender. Great for getting more leverage on a wrench when a pipe wouldn't fit over the end of it. Much safer than latching two wrenches together.
