Default No loctite on swingarm pivot bolt?

Hi All,

Swapped my black swingarm for a Harley chrome swingarm last night on my 2012 XL1200V. I had new bearings pressed in to the chrome swingarm so it was a breeze swapping it out. My Harley service manual states to torque the bolts to 60-70ft lbs but doesn't mention any loctite. Is there any reason to put some blue (or a single drop of red) on the bolts before I start reassembly of the rest of the bike?

Thanks.

I would add a drop of blue on those swing arm pivot bolts.

I believe those two bolts are on the annual service check critical fasteners list.

That's my 2 cent comment.

If you add loctite (since it is not called for), reduce the torque value.

Thanks guys. I'm in between on this one. I definitely don't want one or both of these bolts backing out, but I'm also not able to get a torque wrench on them once I put the exhaust and passenger foot peg brackets back on.

FWIW, the bolts didn't appear to have any loctite on them previously. I've just learned to loctite everything usually. The only bolts/nuts I haven't loctited in the past are the exhaust flange nuts and the upper shock bolts.

Hi,

I’m not sure if this will work on a ‘12 but this is what I did on my ‘96.

After everything was was cleaned and repacked I cleaned the Allen bolt and threads in the pivot shaft.

I then threaded the Allen bolt into the pivot shaft before slipping it through the frame and swing arm. After the pivot shaft was through I removed the Allen bolt and slid the swing arm bushing into place.

Doing it this way prevented the threads in the swing arm shaft from getting grease on them. I then applied some blue thread locker and tourqued to 50lbs.

I tightened the bolt from 35 to 50 in 5 lb increments checking that the pivot was moving smoothly.

Hope this helps,
Craig

Thanks Craig.

On my 2012, the bearings don't need to be packed and are pressed in to the swingarm with a snap ring to hold it in place, so getting grease all over the place shouldn't be a problem.

I think I will pull the bolts and put a drop of blue on them, and torque to 55/60 ft pounds so I don't have to worry about retorquing them.

The bolt still needs doing up to the specified setting.

Blue is medium strength and will be easy to undo. If in doubt heat the socket before putting to the bolt and it will soften the Loctite.

Hes is saying the locktite will give a false torque reading and will be excessive if torqued to spec.

EDIT: I stand corrected

Page 21.

You learn something new every day. Cheers.

As the service manual gives a range for torque settings maybe just use the lower figure.
