In regards to the bolt loosening as the crank settles in...
During a MTB ride someone noticed that a friends crank bolt was
missing (gone, disappeared, it's outa here!). The crank seemed tight
so he decided to keep riding. He finished the 90 min MTB ride with no
problem and installed a new bolt
Best of luck with the crank Eric!
I've had a crank come loose far from home and didn't have the 8mm
wrench to tighten it. I thought I had "damaged" the taper. After
cleaning up, greasing, and torquing (properly this time) it has worked
fine ever since.
Now I make sure I have a tool to fit the c
Reading this short piece by Jobst Brandt (courtesy of Sheldon, RIP)
was very important in my education regarding square taper cranks, it's
worth a look:

Reinstalled the Sugino this morning. Wiped all the grease off the
spindle and off the crankarms. Torqued down to recommended. Then
went riding. Including some hills that were grunt up quality.
Stopped three times in 30 miles to check the tightness. Including a
stop at Hiawatha Cyclery and borr
Chuck is right; the pressure on the grease is great enough to negate the
difference between "enough" and "too much'.
I torque mine to (forget what; have it marked on my torque wrench) and then
ride forever after with no problem, never bothering to retorque. I think it
is the initial torque that, i
Although a thin coat is probably best, it would be hard to damage a
crank by applying too much grease. The excess would just be forced out
when you applied the proper torque. You can damage them by riding
when they are loose - as others have said, I re-torque after the first
few rides...

The arm, without tightening down, seems to sit on the spindle
"funny". Not like the right arm does.
However, it could be I had over-greased everything. But that would

Eric,
Why are the cranks "beyond repair"?

Well, it may have been too much grease on the spindle. Quite a bit
when I cleaned it off. Things were fine for a month or so. Then the
looseness became apparent.
Frustrating as two cranksets are now beyond repair. Couldn't even
make a single work, as one was 170, the other 175. Sigh.

Had a similar issue recently with my XD 600, I had used too much
grease on the spindle in order to eliminate a squeak issue,. turns out
it was the bb instead, and had a couple instances of the left (non
drive) crank coming loose. After wiping down the spindle and cranking
down on the crank arm bol

I go to 28 or 29ft lbs with Sugino cranks and the thinniest posible
film of grease. Never a problem.

Eric,
I have had a couple of crank arms looses...it has always been my
fault.
When I torque the crank-arm bolts I have not had one come loose. I
torque to 25-28 ft-lbs although the recommended value varies from
crank to crank and non-square drive cranks (which I don't own) are
probably different
I have found for me that it takes about 10+ rides of check and tighten
after every ride before it's set and won't tighten any further. After
that it seems to stay that way forever.
