Deore crank: spider coming loose!
Hi.
I've got a Deore Hollowtech crankset, just over a year old. In that year, I've put some serious milage onto it, but no other abuse. I was very unimpressed to discover that the spider is now loose (has play) on the crank arm. I think they're attached to each other with splines, but it doesn't look like they're designed to come apart, so I can't really check that. What I'd like to do is take the spider off the crank arm, and then put them back together again with some bonding agent (Loctite/Epoxy?) on the splines. Has anyone managed to get the spider off the crank arm of Deore cranks before (without writing off the crank set)? If so, how? The dealer that sold the cranks to me (as part of a complete bike) told me that the guy who evaluates warranty claims said that this was "normal wear and tear", and not covered by warranty. I've been thinking about this: How can it be normal if the orginal chain rings are still okay to use a new chain (they are), but the actual cranks need replacing? Maybe Deore cranks have bolt-on chainrings so you can replace the arms and spider regularly, but re-use the same chain rings! Thanks for any help, Travers |

Thanks for any help, Travers Deore cranks are so cheap it's not worth investing much time or effort in trying to repair this one. On the other hand, there's no way this swaged junction should start coming apart before the rings wear out, so you should be hassling your shop, the bike company and Shimano over premature failure.
