Oilhead Valve Adjustments for Dummies – 2003-09-23
Ok – so it is REALLY hard to communicate the feel of ½ snerk on paper. The
best we can do is show you the illustration above, and give you a couple of polar
extremes to avoid…
Do NOT just make the locknut finger-tight, or tighten the locknut just a little bit.
You’ll be paying the big bucks for someone to dig it out of your engine block 50
miles from now, and…
…you most definitely do NOT want to be doing this…
This tender little expression of leverage would rip the shit right outta threads.
IT IS NOT A GOOD THING to over torque the locknuts. Go for that smooth ½
snerk shortly after real resistance is felt. Use a slightly disabling grip, and the
thinnest, flattest 10mm box wrench you can find, and you’ll be fine.
But more importantly, develop the feel for consistently repeating this amount of
torque so that all 4 lock nuts are the same.
Also, be aware that other wrench’n techniques will work. It is important that you
find a means to apply the desired ½ snerk consistently, if this means using a
different grip at the end of the wrench instead of choking up on the wrench with
your whole hand that will work as well…It’s the ½ snerk every time that is
important.
