Removing a Sakae Crank

VeloJon said:

I need to remove an mid-80's Sakae crank off an old Shogun 600. The
crank bolts have a large horizontal slot with diamond-shaped hole.
Since my meager wrenching skills only date back to the mid-90's, I am
unfamiliar with this beast. Any cheap suggestions that don't involve
buying an expensive tool I will never use again?

I think you're just talking about old school dust covers? I have a
similar Sakae crank on an old bike and it has dust covers covering a
14mm crank bolt.

And, if it is a dust cover, it is a screw-on hard plastic one, not a push-on
soft rubbery one.

Large screwdriver should remove it easily. If it shatters due to age, a
modern cover will do the job.

A quarter works nicely.

You'll need a crank extractor, about $15 as well as a coin. Depending
on the clearances around the crank bolt that'll be exposed, you may
need a thin wall socket to get in there. My vintage SR crank on one of
my bikes is a tight fit--so I bought a $3 socket, and ground it to
fit. I'd replace the crank arm bolts with some modern allen wrench
ones that serve as both bolts and dust cover, well, only if you break
the dust covers.

That's just a plastic or metal cover. Use a cone wrench or a quarter to
unscrew them. Your crank bolts are under those covers, the extractor is
the standard 22mm tool.

I just pulled a Sakae off an old Cannondale. As others have said, just
use a flat-blade screw drive to take the dust cover off. Then the right
size socket to back the crank bolts out. And then the black-handled Park
crank extractor (#4 as I recall) to pull the crank arms.

Hello,

I'm in the same situation. I've got this old bike equipped with a (SAKAE) SR-SC 1.37" X 24T Crank bottom.
I live in Denmark, the land where almost everyone commute using a bike. So you would think the "know-how" is substantial.
Apparently not so. Of the three bike repair shops I've talked to so far - none of them could give me the right answer.

How do I remove this crank bottom? It's broken and has to be replaced.
Haven't found any useful tools yet.

And yes, as the picture reveals I did loose my temper and went totally mental on this thing with a large wrench.

Threading is right-hand on the left cup (your pic). Your lock ring is off and now you can tap off the adjustable cup with a brass drift and a hammer. After loosening the threads with the hammer/drift you could probably use one of Park Tool's Adjustable Pin Face Spanners to continue turning the adjustable cup.

The right side (fixed) cup is left-hand thread and uses a standard type BB spanner.

If you can get the fixed cup off the opposite side and pull the crank spindle out, you can make up one of Sheldon Brown's el cheapo cup removers:
