How to remove cranks with 15mm bolts
I usually have no problem removing cranks. I use my 14mm socket wrench. I
have a bike that appears to have 15mm bolts. My 15mm socket won't fit in there. Is there a special tool for these (I would guess early 80s) Sugino cranks found on a Univega. |

Sounds like your socket has a thicker wall than mine (12-point Sears Craftsman), it works fine on all my 15mm-bolted Sugino cranks. Sugino made a socket with a built-in T-bar, or there's the 15mm Park (or Campagnolo) "peanut-butter wrench": http://harriscyclery.net/site/itemde...466&Catalog=39 I'm guessing you could save a few $ with a trip to Sears for a single 15mm socket. Take your crank dustcap in and make sure the socket has a smaller diameter. Regards, Mark Janeba |

Or get a crank remover with 14/15 sockets included. Or a trackie's "peanut butter" wrench. -- Andrew Muzi www.yellowjersey.org Open every day since 1 April, 1971 |

Grind the outside down if you cannot get your hands on a slim wall type. Otherwise a tubular spanner will do the job (better to carry on the bike). You may refer to it as a pipe spanner (not for pipes). Trevor |

To be more specific, look for a premium quality 3/8" drive 6 point socket. I've never found a 1/2" drive socket that will work here. (Generally, higher quality sockets have thinner walls and better clearance. Cheap sockets make up for lower quality steel by using more of it.) Then again, It might make more sense to borrow a suitable socket to remove and discard the 15 mm bolts, then buy a pair of newer bolts that use either 14 mm socket of 8 mm Allen wrenches. The bolts will likely be cheaper than a suitable 15 mm socket.

The bolts will likely be cheaper than a suitable 15 mm socket. This has the added advantage of eliminating the need to have two tools to get crank bolts out. Should the need arise to remove the crank again later, no added time need be lost looking for the thinwall 15mm wrench. -- Typoes are a feature, not a bug. Some gardening required to reply via email.

Is your 15mm socket a 1/2" drive? - ----------------------------------------------- Jim Adney Madison, WI 53711 USA ----------------------------------------------- |
