Misc Torque Specs - Use at your own risk! (FAQ)

[Hugh Heifer]

First I have to say I had nothing to do with any of this other then compiling it. If your bolts shear off thank somebody else.

It seems folks often have questions about proper torque settings for various items on their 40’s. I figured as an ex-helicopter mechanic, I would do something that may be useful while I drink my beers.

First I searched Mud for torques and found about 75 posts and weeded through them for good ones and applicable ones. This is what I found:

“There's a generic torque table, by bolt size, in the back of the FSM.”

“Torque specs are [usually] determined by the bolt used, not the application. You should be able to find standard specs for each size, grade and the tread pitch, both SAE and metric by searching the internet. Although popular, OP never uses Locktite but prefers Never-Seize. It makes the bolts come apart easier later and it is water proof when used in the wet spots. OP uses NEW lockwashers: split-ring, highcollar, I/O stars, etc. OP used to have an old engineering manual that said those are not designed for multiple uses, so considering the cost, OP tries to always replace them. [sic]” Sound advice on the washers as an ex-aircraft mechanic.


“…verify that the threaded holes are free of dirt, grease and or oil and install these bolts using blue Locktite…”

[Hugh Heifer]

Now for the miscellaneous posts (I left out the names and cleaned them up to protect the innocent):

Water Pump Bolts
15-25 f/lb (1964 FSM)

Pressure Plate Retaining
8mm diameter fasteners 11-15 foot pounds

Shackles
36-58 f/lb FSM

Differential Bolt Torque Specs
34 ft. lbs from the 1990 FSM

1981 2F Head Bolt

Connecting Rod - F Engine
The FSM says 35-55 ft-lb. for the con rod caps


Remember - these are from your fellow members! I am just putting them inone place....

I also came across this from AutoZone and it appeared very useful if correct:

[Hugh Heifer]

It is late on the East Coast so when I have an opportunity I will be glad to load the FSM Torque Specs as well as the Generic Torque Specs listed in the back of the FSM and else where.

HAVE ANY RELIABLE LINKS TO TORQUE SPECS???? LINK 'EM HERE!

If you want to list a "Gutentite" please advise it is such and not FSM or other manual. Also - site your reference in case folks have questions.

And for now,

Here are some decent Web Sites I have come across for SAE threaded bolts as I have been doing this:

U.S. BOLT TORQUES SPECIFICATIONS AND FACTORS


For the real Engineer - The FUTEK Online Torque Calculator


Torques for SAE Grade 5 and 8 Fastners (oiled and dry)


SAE Torque Specs for Fine and Course Threads Iron and Aluminum

[Hugh Heifer]

And finally (and probably more importantly) some generic sites on metric bolt torque:

Metric Torque Specs for Fine and Course Threads Iron and Aluminum


The FUTEK Online Metric Bolt Torque Calculator


A 2 Page PDF that includes a computation for surface condition (more then you need)


I guess that is about all the damage I can do here. Hope this helps somebody that keeps breaking off 5mm bolts with 188 foot pounds of torque!!

[Spud]

Awesome...Thanks for taking the time to do this...
