Hope this is the right place to post this.
I am installing a Ultegra BB-6500 and need the
torque values for the install. Can someone help me
with this information?

If no one here can help you, try re-posting your question in the Bike Mechanics forum.

Granted, this is for the 6600 BB, the torque values can be found at:

I thought the 6600 was the external bearing, while the 6500 is Octalink. Probably different specs.

Alright, in here it says the torque should be 35 ft/lb.

No. According to the Shimano Service Instructions, tightening torque is 435-606 in-lb, or an mean of 43 ft-lbs. 50-70 Nm for the metric guys.

Take the fixed (R) side down kinda tight but don't torque it. Then take the separate (L) side down kinda tight. Then torque the R, then the L.

go to parktool.com under repair help, misc topics .they have a complete list af all shimano torque values.

probably doesn't make a difference because most torque wrenchs won't fit your BB. Just put it on there as tight as possible as the torque value is high.

...or you can use a dumbell that's laying around the house and hang it from the wrench at the correct moment arm to produce the torque needed...

...not that I've done that or anything....nothing to see here....move along, move along...

Okay, got it. A thanks to everyone for the help.
This is a great place for information.

NO. Different BB design and different torque specs.

Here are the 6500 Service Instructions.

tight enough without having to jump on the wrench
