putting a tractor back together.

can't find torque specs for flywheel and clutch on this antique ford.

I've got 7/16 NF and 5/16 NC bolts. How tight?

Tighten until things deform, then back off by 1/2 a turn.

How antique? The 39-48 Fords used (essentially) model A engines -- with
some digging you may be able to find the torque specs for that.

As of a couple of years ago, one of the fellows that works in the
service department of our local feed store was an old Ford tractor nut.
If he's still there, call Fischer's Mill Supply at (503) 631-3411 and
ask for Will in service. http://www.fischermillsupply.com/. Even if
Will's not there, I think you'll get sympathy from a company that
dedicates a good part of their tractor shed to a 12-foot tall, 18-HP
steam-powered monster that they keep in shape for antique tractor shows...

(When I called, Will in Parts answered the phone, transferred me to
Bill, who runs service, who got Will, to talk to me about my dad's 41
Ford-Ferguson. So ask for Will _in service_).

Milady found general specs. vs. bolt size. I'm going with 65 and 20

Look up the torque for the bolts you are using. See
http://www.raskcycle.com/techtip/webdoc14.html

the only things i use a torqu wrench on are conrod bolts, main caps and
cylinder heads...

just tighten them up fairly hard.

IOW, you *don't* use one on brake or suspension components? Not wise.

Anything that just doesn't need to come loose by itself (as opposed to
needing a specific clamping force or an even clamping force across
multiple bolts) just need to be tight enough.

Telling what fasteners are doing which type of job is of course one
way to get into trouble with that philosophy.

Lug nuts are on the hairy edge of really needing to be done with a
torque wrench or not. Some cars you do really need to use one, 99.nnn%
don't need it.

Yabbut, on disc brakes, which every car now has, it's HIGHLY
recommended. That said, once you've done 1,000 of 'em, you develop an
internal torque wrench of your own.

I once needed a tire fixed, they let me watch them do it. The tire kickers
actually used a torque wrench on my lug nuts! I wanted to buy them a pizza
or something!

I was kind of surprised when I learned that the reason for a torque spec
is so that the bolt doesn't get _over_ tightened!

My usual tyre dealer ( family business ) insists that his staff
tighten all nuts by hand using a normal 4 way tyre spanner. They
remove them with a rattle gun though. He also insists that
customers return every 10,000 km for a FREE tyre rotation and wheel
re-balance. My last set lasted over 100,000 km as a result. Having
moved away from the area I now travel 80 km for my tyres at very
competitive prices.
