...crank arm removal.
The screws normally needs a 14 mm socket, but mine doesn't fit, nor do my 15 mm socket. The screws have campagnolo printed on them so there's no funny ones. The crank in question is a record, and my 14 mm socket worked well on my campa chorus cranks.
I'm thinking, could it be that I need a 9/16" socket, which is about 14,3 mm. Inches on Italian screws is not likely though I know, but I have to ask.

Which Record?

Screws? You mean bolts?


Older Record, Nuovo Record and Super Record took a 15 mm wrench.

EBH

Nuovo or Super, not entirly sure, but from ca. 90'. and yeah bolts.

EBH

15 mm, ok, then my standard 15 socket has a too large outside diameter.

rootboy 

Was just asking because I'm totally unfamiliar with later Record. Better confirm with someone more knowledgable than I.
Yes, the too thick walls on many sockets is common.

EBH

Ok, rootboy, thanks. Perhaps someone else on here can confirm.

You most likely need a thinner walled 15mm socket. I cannot use the 1/2" drive 15mm socket on my set-up but the 3/8" drive 15mm will fit inside the crank threads (that is where your present 15mm socket might be hanging up), allowing me to easily remove or install the Campy spindle bolts. Stronglight - 16mm - for that I had to grind the wall of my 16mm socket.

I had the same problem. Tried about 4, 15mm sockets I had until I found one with a thin enough wall.

dedicated crank bolt wrenches are not that expensive, single sized park wrenches are about $11 on ebay, and park used to make one w/ 14, 15, 16mm, which show up on ebay occasionally.

I took a socket to the grinder for mine, then two years later I couldn't for the life of me remember where I put it so I ground down another and then promptly found the first.

EBH

Ain't that typical...

Cheers folks, seems like a 15 purpose made or ground down is the options then.

At the bike shop we have a swivel wrench one end 14 the other 15mm the 15mm side has the walls ground to fit Campy,this tool is a workhorse and is used almost every day

We all have that drawer of improvised tools that work - They vary from miss matched sockets to pieces of bent wire and shims to odd looking bolt and wood contraptions - All more than valuable - And don't even ask to borrow any of them - I try to mark them with spray paint once they are found so they don't get mixed into my regular group of tools - I wonder if they talk to each other in the drawer - Most of them must at least speak French or Italian...

Thats just the fun of it...

Oddly, Robbie, my Snap-On 15 mm socket won't fit in my Record cranks. I bought the tool in the early 80's but I don't know if that has anything to do with it.

Craftsman 15mm are thin wall..

lostarchitect 

+1, my Craftsman fits fine.

The stories about grinding reminded me of why I have a 5/8" (poor man's 16mm) socket whose outer diameter I had to reduce w/ the grinder for some Stronglight cranks I used to have. For 15mm crank bolts, I normally just use my Park tool, and 14s are never a problem.

Went to the flea market over the course of several weeks and tried nearly every 15 mm socket there. I finally found an older Craftsman socket that had sufficiently thin walls to fit.

I have the easiest solution though might be difficult to find a Campi Crank extracter and the wrench that went with it works on Record cranks Shimano and Suguino and C-Record era cranks.
Those are all that I've used it with.

What do you mean by "ca. 90'"? If you mean circa 1990's, then your talking C-Record; C-Record did not use hex crank bolts. The early C record (1985-86 I believe) had self- extracting crank bolt with a reverse threaded retainer ring and a 7mm allen head screw; Campy later went to a standard 8mm non extracting bolt. The reverse threaded retainer ring and a 7mm allen head screw had many issues that caused Campagnolo to re-think the design. #1) if the reverse threaded retainer ring was lost, you needed a reverse threaded crank puller, #2) 7mm is not a standard size allen wrench that comes in a set, #3) a standard allen wrench did not have enough leverage to extract the crank, resulting in this wacky looking tool. that connected a 7mm allen wrench to a Campy 15mm crank bolt (aka peanut butter) wrench. BTW Campy also sold a reverse thread crank puller..



Edit; To clarify when I said C-Record I meant C-Record, not C-Record era, since the OP said he had a 90's Record crank. Several C-record era cranks other than Record had the reverse thread extractors, those being Croce d' Anue and Victory. I believe the other cranks, Chorus, Athena and Triomphe had hex crank bolts.

rootboy 

All I've ever used was the fabled Peanut Butter wrench.
But I did check my sockets after reading this thread.

callig

I have an Athena crank that I bought in 89, 90 not exactly sure when it has a bolt on cranks my C-Record crank has a self extracting crank bolt that takes a 7 mm hex wrench

Italuminium

My cheap and cheerful chinese crank extractor has a little clip-on socket which fits 14 mm on one side and 15 mm on the other - only not tolerances are way off, so there's too much play when actually using it. Besides, it's made from peanut butter grade steel. But beggars can't be choosers.

EBH

Sparked alot of discussion this tiny question. This is the crank in question.
