I’m tired of taking my bike in for nickle and dime little repairs so I’d like to start doing the minor stuff on my own. Which crank puller do I need to use on Ultegra 9 sp. I’m thinking park tool CCP 4. I need to do some maintenance on the bottom bracket that would require me to remove the crank arm.
Park tool description
The CCP-4 is specifically designed to remove crank arms from Shimano® Octalink (splined, oversized “pipe billet”) spindles, and ISIS Drive ® splined systems. It uses a long, comfortable handle and a fine thread for the leverage needed to remove tight crankarms. Rotating tip ensures smooth operation and long life
You actually need the tool you listed and a little nub looking thing. It’s a widget that gives the crank arm extractor tool something to push against. If you lie it on the end it looks like a “T” but is obviously round.
The bolt is self extracting but the crankarm is not. I’m in the shop, looking at an Ultegra 6500 crank, referencing Barnett’s Manual. The specific widget is called the spline adapter and is used if a spline-crank specific tool isn’t available.
Try and see if your Octalink/Isis cranks remove themselves after taking the crankarm bolt out. Ours in the shop don’t unless the crankarm bolts weren’t torqued up.
Please tell me that you are not the shop wrench. Ultegra 6500 cranks come with a self extracting crank bolt. By turning the crank bolt counter-clockwise you will remove the crank from the Octalink bottom bracket. The crank bolt will stay in the crank arm. Here is the quote from the Shimano service instructions:
“The crank arm can be removed simply by turning the fixing bolt counter clockwise”
I am a shop wrench and mature enough to admit that you’re right. However, I was taught to remove the dust cap and use the tools I described as they are stronger and can handle more force than simply using the dustcap. Either way the crankarm will come off with neither method being better than the other.

Lord man… it’s not a “dustcap”, it’s what makes the crankarm bolt self-extracting! And you don’t need that “widget” (as I believe you called it) to remove Shimano crankarms from Shimano bottom brackets when not using self-extracting bolts … that’s for Isis bottom brackets, not Shimano Octalink ones. What kind of bikes do you work on?!
