Re: Torque vs Thred pitch

 

I watched a fast pro/privateer off road racer change the rear wheel on
his KTM. He torqued the axle nut by standing on the wrench handle, and
bouncing up and down exactly 2 times. Perfectly tightened, I guess...

The only time I ever used a torque wrench was for 1968 Ford head bolts,
and I couldn't pull hard enough.  That was the only thing about the
head-gasket/valve job (aside from the machine shop work) that I didn't do.

And hated every minute of it. Other hated jobs:  (1) cutting my fingers
to ribbons replacing a water pump;  (2) replacing stubborn motor mounts
when the engine was held up by a floor jack and I had to try to get the
old mount out with my fingers potentially part of a finger sandwich. I
ultimately left the old one in and stuck the new one on top of it; it
worked;  (3) ripping the shorted alternator out of my 1980 Suzuki GS550
-- I never did replace it and I still feel guilty about it.

Lots more, of course...

Why do men's hearts beat faster, their knees get weak, their throats
become dry and they think irrationally when a woman wears leather clothing?
Because she smells like a new truck.

 
People get on me cause I use a torque wrench for everything I can. A few
weeks back we were visiting another track and a guy did a big step up
over a hill. When he landed, his bars collapsed and he went over, broke
both wrists real bad. I was one of the first there and when me and
another guy grabbed the bike to pick it up, the bars (which were facing
down) rotated right back to place, obviously they had not been torqued
properly. These were very bad breaks, I wonder if the kid will ever ride
again...

Torque wrenches are good, but don't help if you forget to use them.
that's probably what happend to handlebar guy.  I never put a fastener
on/in unless it is fully torqued, even if I am just going to pull it
out again.

One of my friends had just got his KTM 300 EXC forks back from Factory
Connection.  5 minutes into the ride, while he was crossing a very
rocky section of road and was tapped (~50-60MPH we figure), his bike
high-speed wobbled and promptly tossed him off.  He was a bloody mess,
and his elbows were both the size of his head (and he had guards on).
Turns out he forgot to torque his triple clamps.
