Don't get anal about bolts and torque!

[Bob A.]

I searched my old Motors manual ('35-'50) and the only torque specs I found under Ford was for the head, but "only when a torque wrench was available". So who's right, who's wrong ? I think Marco hit on it.

I'm guessing your Motors Manual is a 1950 version. It would be interesting to find the first printing of a Motors manual that includes any mention of torque values.

It appears the first patent for a torque wrench was 2,159,354, granted in 1939. It's interesting that the patent application mentions "the tightening of cylinder head nuts on internal combustion engines or assembling precision devices such as air craft engines and the like"

I'm really curious when torque standards were finally adopted by the auto industry.

Reminds me of the exchange on "proper torqueage" in My Cousin Vinnie. Marisa Tomei's performance was inspired. If you haven't seen it in a while, go through the $5 bin at WalMart and get it! Great motorhead movie!!
As for proper torque application being related to the leverage of graduated wrench lengths ... I am in need of a new set, with each wrench about 3 inches longer than the set I bought back in '75!

Also Marco, My old Dyke's Book (Nineteenth Edition) Published in 1942 Doesn't mention anything about a torque wrench or torque specs..

Most people miss the first step in tightening anything..forethought.. at 20 lbs. the pan gasket IS split at the bolt hole!
A lot of you guys have done this ALL your life, some 1 or 2 times , this maybe there first experience with taking anything apart! I have 4 torque wrenches and they specifics uses. At one time or another I have torqued EVERY part on an engine, depending on it's use or design
This mite be a good time to write a list of what type of tools to use were(the RETIRED guys are the writers), for the folks that are lost or need a hand? Think about this, I saw somebody tighten a rear axle nut with a 12" Crescent!
