How to Remove Shimano Cranks

BeeRich said:

Hi folks.

I want to remove my Shimano cranks (XT) and I can't seem to get them
off. I took out the hex nut, but she's pretty solid. Do I need a
puller at all?

Yup.

they are on so tight.

I just shot some lubricant in there, and I'll give it overnight to
penetrate.

Any advice needed.

You need to know *which* XT cranks you have. Take a look at

and

and

to determine which you have. A picture would help.

XT cranks are two piece, the spindle being permanently attached to the
right crank, the left one, the removable one, fits on a fine spline
and is secured by two pinch bolts. Loosening the pinch-bolts allows
manually pulling the crank off the spindle. Assembly should be with
grease between spindle and crank to prevent corrosion and facilitate
removal. This is not a friction joint and gets its strength from face
contact pressure between crank and spindle spline ribs.

When you say you removed "the hex nut", I suspect you don't have these
cranks:

If its not a ISIS drive. You need a puller and it better be a real
good one. There may be a washer from the removed Allen or Hex bolt in
there. Had that happen once.

If you have a Hollowtech(spline type BB), need a little plug,
available at the LBS, for the puller to push against. If you have
square taper XT cranks, just the puller..make sure it's screwed in all
the way. Don't use the self extractor cap, if there is one, these caps
are aluminum, cheezy and if the splines(if HT) are not greased, this
will blow up.

Hi there. I don't have those cranks. This bike is from 1992.

Ah so. Those are some of the best cranks Shimano ever made: one-piece
forged arms (no seperate spider) and 110/74mm bolt pattern, square
spindle. That's probably mumbo-jumbo to you, but, speaking as someone
who's been around bikes for (eek!) 35 years, if you ever want to sell
them, I want first dibs.

They are also 180's, so I knee my chin when I bike.
