This is an LX crankset, Hollowtech, the first year of the really wide crank arms and the see from one side to the other BB.

I removed the crank bolts and was then at a loss. Unlike the 03 version, the bolts did not bring the crankarms with them upon removal. Are the arms themselves threaded onto the BB spindle? There are both threads and splines apparent on the crankarm.

Help.

I should do some research before I post this stuff. I'll answer my own question in the interest of future searches for this info.

Apparently I need a crank puller other than the one that used to work for my square taper BBs. Park sells it. Correct me if I'm wrong?

Still, it begs the question, why go from self extracting crank arms in an earlier model year to a version that demands a special tool? Just for the hollow BB? Please.

Helps to know what specific crank you've got when asking questions, last time I tried to decipher a description I guessed wrong. Shimano's Hollowtech has two versions, Hollowtech I uses a three piece design (separate crank arms & bb) with a somewhat traditional cartridge bb with internal cups; Hollowtech II uses a two piece design (sort of, two crankarms, the drive side arm having a permanently attached bb axle) with external bb bearing cups that fit around the outside of the bb shell. Another way to be specific is to look on the back of the crank arms and see the model number Shimano stamps in. Once the crank bolts are off you can see thru the "I" and you can always see thru the "II". Harder to keep track of Shimano by year.

That said, I think you've got the older version, just didn't have self-extracting bolts.
Need a Park CCP4 I believe. Shimano loves changing stuff to make it proprietary and self-obsolescing.

But isn't is cool to have hollow bolts so you can see through your hollow axle?

You don't need a new crank puller, you just need to buy one of these. They cost CND$ 10 and most bike shops carry them. As you can see it is a Shimano part with part # TL-FC15. It works with both Shimano octalink BB's and ISIS BB's. You just drop it into the hollow axle of the BB and use the crank arm puller to push against it.

Wish I'd seen one of those before; I got a CCP4 a while back, even though don't need it for my own cranksets, got it more to have a more complete toolbox for when wrenching on a friend's bike or a future crankset.

Sorry, but there is no excuse to not have self extracting crank bolts on an '04 LX crankset. It would cost squat to add them to the crankset. Do yourself a favor and buy some. I had to on a set of 2005 Bontrager cranks. I was pissed when I noticed they did not come with self extracing bolts

Wow, very cool. Thanks for showing me that, I'll find one right away.

As for the lack of self extracting bolts on that crankset, I think it's kind of funny that the same cranks came stock on my wife's one year old hardtail, but with the "cool" bolts instead of the see through, need another tool version.

Thanks for the help.

So last night I'm looking for that Shimano tool to drop in the crank arm and give the crank puller something to push against. On the way, I found a bolg entry by someone obviously annoyed for any new tool to pull these cranks who said that dropping a penny in the hole and pushing against that would accomplish the same thing the Shimano tool does.

How about that?

As long as the OD of a penny is smaller than the ID of the crank arm and you can position it correctly while pushing on th BB axle, sounds like it would work. A penny is soft so it wont damage the axle as it is deformed from pushings against it.

But hey, what would be the fun in that, this is a chance to buy a new tool!

I just drop a hex nut in the hole, Im thinkin a 3/8" nut or so, big enough so it doesnt pass through the small hole, and use my old sqr puller. No biggie.

Agree

I agree with Fisty, the old hex nut and square puller works and it's cheap.
