Torque specs
Can somebody point to me a source for typical recommended torque specs
for things like chainring bolts, crank bolts, etc? I've checked the usual source (sheldonbrown.com), but can't seem to find it. -- Dave Kerber Fight spam: remove the ns_ from the return address before replying! REAL programmers write self-modifying code. |

may have said: Can somebody point to me a source for typical recommended torque specs for things like chainring bolts, crank bolts, etc? I've checked the usual source (sheldonbrown.com), but can't seem to find it. Someone else has already provided the link to Park. I'll point out that they don't tell you some of the things you'll eventually learn by experience. One of those is that a torque wrench is a nice tool, but it doesn't really tell you if a fastener is tight. It just tells you how hard it's being turned. To get those two to coincide, everything has to be done right; the proper spec has to be in use, the fastener has to be in good condition and have clean threads, the parts being tightened have to be in good condition and properly aligned, and in some cases there may need to be a lubricant on the threads or on the mating faces of the pieces being joined. For square-taper cranks, I recommend reading this page as well: http://draco.acs.uci.edu/rbfaq/FAQ/8f.11.html -- My email address is antispammed; pull WEEDS if replying via e-mail.

Torque specs
There are two related links on the Park Tool web site,
See both http://www.parktool.com/repair_help/thread.shtml and http://www.parktool.com/repair_help/torque.shtml The second one does include a discussion of fastener tension, which is what holds a fastener secure. Torque is used to achieve tension, but it is the tension that is really needed. There are no "Park Tool torque recommendations", only listing from various manufacturers. |
