Torque Specifications

Recommended Posts

I didn't see this via a quick search, nor in the FAQ section:  But something I've found very useful for other vehicle DIY maintenance is a simple consolidated list of bolt torque values.

 

Generally, although not always, these torque values can be found in various tables and buried as part of some loosely related assembly instructions within service manuals. But that can be frustrating to search for when performing a repair, or just trying to prep for some assembly work.  

 

And sometimes no values are provided by the factory for some fasteners at all.

 

So it might be nice to start a thread of fastener torque values as owners research and find them, and perhaps over time make it a FAQ.

 

For example, I'll have to replace my front engine mount sub-frame at some point due to rust, and I'd like to know what the frame and engine mounting bolt torque values are.

See Section B-4, page B-12, of the Workshop Manual. Most fasteners on the V11 are torque spec'd by their size and not location/application.

The WHB's do have a list on some page but it's incomplete - many settings are not included but scattered around at specific sections (which is good too but they should be in the list as well  :oldgit: )

 

I collected all I could find when I had the 1100 Sport (all or nearly all will apply to V11 as well) plus some generics, see this page: https://www.abc.se/~rasmus/1100Sport-torque.html

That is excellent, and exactly what I was looking to collect!

 

Would you mind cut/pasting that list to this thread also in case something happens to your location one day, and we can have that information here for easy reference?

I'm notorious for Excel-masturbating when weather or light isn't suitable for riding, it's a good thing others get some use of it  :mg:

Thanks everyone!

 

Here's my thought, as others come across new values specific to a component or find a correction we update the thread and ultimately the master list.

This begs the question where to put this information.  FAQ threads are locked. So, a page could be put there, but cannot be amended or added to by the membership. We could leave it here and hope a search will bring it up, but the search function really works best with the:

Advanced Search function and this tutorial.

 

Recently, the several pinned threads in Technical Topics were moved to the "How to  . . ." subforum. While discussion remains open, the "Answered" function was lost. I intend to talk with Jaap about restoring it as it makes "getting to the bottom of things" more approachable.
