snap-on's 'wrench force' crank puller is the one to use. $7 or so and works simply and perfectly with an adjustable wrench. the park one with the built in handle is for ****.

The site states that the threads directly on the crankarm (traditional extractor threads) are reverse thread, when the self-extracting bolt has been removed. The bolt itself is standard-thread.

Snap-On makes a crank puller? My oh my.

Actually my reaction was more along the lines of..... Snap On has tool that is only $7?

HA! Yeah, right BG. I thought that must've been a typo!

Cut and paste from your site:

"*Campagnolo's C-Record, Croce d'Aune, and Victory use 22mm left-hand extractor threads on the left-hand crankarm only. "

That statement is wrong. Both crankarms are left hand thread. The phot in my original post is of the bolt from the drive (right) side and is obviously left hand threaded.

The comment I made about right hand thread was to demonstrate that it made no sense to have one side left and the other right, given that both crank bolts are right and the point of having the extractor left threaded was so it didn't unscrew with the bolt.

Mind you there's a long history of decisions that make no sense in crank bolt and extractor design, as per earlier posts in this thread.

Snap-on makes the tools for Trek's "Wrench Force" product line.

True, but this is only a concern if the self-extractor components have been lost.

Yeah. I read they are already defunct, and that the tools were "engineered" by Snap On, which doesn't equal "made by", but, I also read some very good reviews.

In the early '90's, a mechanic friend removed the crank extractors in my C-Record crank. I had bought an SRP Ti replacement upgrade kit & two Ti crank bolts were part of the kit. 20 years later (last week), I decided to pull the crank off the bike. The Ti bolts came right off w/o issue. Figuring I could just put the extractors back in I could then easily remove the crank arms. After about a 1/2 hour of trying to screw the extractors back-in clockwise w/ no luck, I thought how could the extractor's possibly even be effective if they screwed in right-handed, when you have to also have to also screw the allen bolt in clockwise for crank arm to come off? Frustrated, I finally tried putting the extractors in counter-clockwise & viola...right in? This is where they are going to stay henceforth....
Righty-tighty / Lefty-loosey does not apply here.

^ Yes, you caught that too JD! Both my C-Record crankarm extractor's screw-in...in-reverse (counter-clockwise). Confusion...?

In other words, the extractor threads (not the self-extracting bolt threads, but the crankarm threads) on both the left and right arms are left-hand thread?

-Kurt

Wouldn't they have to be to use the same tool on both?

Yes, exactly.

I've re-written the site to reflect the correct data; hopefully it is clear enough.

From Headbadge.com:
All fixed... :thumb:

You don't think I had a hard time figuring this all out as well? ...esp being left-handed.

I have to sit and read through this thread again. I believe there was only one or two model of Campi cranks that were LH thread and it may have been only the C-Rec or even just some of them.

I have a Campi LH extractor and I believe I used it once, or maybe bought it after I used the shops tool once.

Excellent - one less page to worry about ;)

(Though I just added a bit to the first sentence so there's no question that the LH threads are on both left and right crankarms.

-Kurt

It's my understanding that Campy didn't stick with lefty extractors through all the c record era. Just earlier stuff.

My reaction is, the brand of the tool does not matter. The threading spec does.

But yeah, I'd expect $7 from Snap On is the price of a replacement Phillips tip for a magnetic screwdriver!

But still, the Campy tool is in the $30 range, which I don't think is out of the ballpark. i've had one for about 30 years - they are not disposable and have no useability issues.

True 'nuf Road Fan. Hard to go wrong with quality tools. My Campy puller is aged too, but still fits like a Swiss clock. Runs like a glove, etc.
