Allen Key Campy 8 speed crank?
Trying to remove an older record crank. I dont have the correct allen key even tho i must have removed several of these cranks before. Is it a 7mm i need (i guess) since 6 to small and 8 to big!
Weird dont think i ever had a 7 :/ |

If the 7mm allen bolt flats get wallowed, striped, you will play hell getting the cranks off...unfortunately, you would also need a LH threaded Campagnolo crank puller too...easy to find, but not cheap. I have one FS, BTW-$70. BUT if you end up using these, take them off, lube the threads and reinstall.

Also be aware that the self-extractor cover in some of these cranks was reverse threaded. If you remove the cover and lose it, you'll need a special reverse threaded crank puller to remove the crank (these have gotten hard to find). |

One ruined crank arm has now been months of hell and expense trying to keep my Campy ride rolling. Just amazing. Doubles with different spindle lengths, fd's that don't seem to have fine adjustment and shifter throws that are comically wide ... and I've redone the cable and tension already LOL |

Trying to keep 80/90s Campag stuff 'going', 8s, is really no easier than 80/90s shimano 8s stuff.

After that fiasco I picked up an alloy Record crank but the chainline was a disaster so I chased down the "correct" length spindle. I bought a full bb and that doesn't fit into the shell in a way I like - too many threads exposed as it screws in a wicked distance. I removed, checked my work and it did it again ... idk, never seen that happen before. However, it does spin and that seems to have fixed my chainline issue Last night I was adjusting the cables and fd and it's just not going as easily as it should. Going from small to big ring I have to push the lever so damn far it's not even funny. It could be that I'm a sucky mechanic, but in the 15 or so years of serious riding I've never once needed anyone's help for such simple issues, or almost any other issue, actually. It could also be that I have a full 6800 grouppo in a box and I'm kinda itching to install it on something haha. |

BTW I am a Campy fan generally but especially the 8 speed. They really hit their stride with this line after some hiccups in the C Record 6 and 7 speed era. Last edited by Spaghetti Legs; 12-09-2017 at 02:18 PM. |

Maybe have the BB threads chaced and have it faced at the same time..by a decent LBS..makes BBs last longer. LH lever is ratcheting friction BUT if fder adjusted, it 'should' take chain from small to big in 3 clicks. Chain really close to inner cage, cable TIGHT...sometimes with the uber adjustable LH shifter(you can use any fder, even a non Campag one)...a few clicks, then center, then push again for the fder. Do some study on the 6800 fder setup..one of the more complicated fders out there(along with 9000 and 5800)...

The BB issue first: The threads are all smooth, but the non-drive side piece threads well into the shell, leaving a few threads of the shell visible. The "cup" if you will is inset of the shell ... not sure if that's normal but I've never seen it before. The BOLDED section: straight my error if you're telling me the three clicks are correct! I like the trim feature of the fd but didn't realize it wasn't supposed to swing up in one motion like all my Shimano stuff does. Well, it does make it but I have to push wicked far and that's why I've been so annoyed lol. I'm going to try it again with a new attitude and see if I like it. Thanks! |

I get that but sometimes 2 or 3 short shifts, movements(clicks) and then it'll shift. Not like the shimano or even sram 'sweep', not positional like theirs are and Campagnolo not tied to their own front der(well, sorta, any sram, road 10s system would benefit from a shimano 10s front der(and cogsets..and chain...)

If I'm getting your story straight, you have a 102 mm cartridge BB which would make it Chorus, Record, or one of the replacements such as Token. All of these are made with a ledge on the drive side cup which locates the BB laterally (same as Shimano square taper BBs by the way). Where the left side cup comes out is determined by the rest of the BB and the width of the shell. I measure an English threaded Campagnolo bottom bracket at 68.4 mm from ledge of right cup to end of threads on non drive cup. So with the intended 68 mm shell width there would normally be a bit of thread exposed when the left cup is tight. If your left cup is seating inside the shell, the shell must be wider than spec, assuming your BB is intact. This isn't a huge problem if the extra shell width is on the left side. If it's on the right it could affect chain line. It could cause a removal problem if the exposed threads corrode.
