Swing Arm Removal

 Is this a task someone can do, or should I take it to the dealer?  As noted
before, I broke off the right lower shock mount that is bolted thru the
swing arm.  Is this easy?

You want service documentation (i.e. manufacturer's shop manual).  If you
don't have this, take it to the dealer.

Never done it yet, but the normal arrangement is just a long bolt, loaded in
shear, through some collars and bearings.  There will be some seals in there
as well to keep out water.  But in the end it is no more complicated than a
door hinge with bearings.

Things to consider:

a)Without having the manufacturer's documentation, you may do things in an
awkward or unworkable order.

b)The swingarm pivot is a structural component.  You want to do things as
the manufacturer recommends, including reassembly torques and any special
instructions.

c)While you have it apart, you probably want to inspect it all.  You also
want to inspect it even before you take it apart for any unexpected play.

d)You want adequate hoist capability.  Remember, to get the swingarm off,
you'll have to be jacking on something that is not the swingarm.

Easy for me, hard for you, unless you know a machinist that can make
you a new stud and drill out the remnants of the broken stud. Then
you'd need a certified welder who can weld the new part in and get it
straight.

If you haven't talked to your $tealer$hip about this and told them how
you mistakenly tried to torque the stud to 100 foot pounds, maybe you
can convince the $tealer that you were just going over the bike,
checking for loose fasterners and when you put a wrench on that nut,
it just snapped off because of a defect in materials or assembly.

Like Datesfat suggests, I'd definitely want a manual,
not so much for taking it apart as for reassembly.
On mine, the swingarm bearings get torqued to maybe
5 ft/lb and the locknuts to about 70. YMMV.

Are you sure you need to remove the swingarm to extract
the bolt or stud in question ? Does it thread into the
arm or run through it ?

You said you had enough stud protuding to actually mount
the shock and ride the bike. If so, you might be able to extract
the stud possibly removing the wheel but not necessarily
the whole arm.

You might want a heat gun, especially if it's a steel
stud in an aluminum arm.

In this case I might consider taking it to the dealer,
seeing as how the actual extraction and reassembly
might be a little tricky and I'd already had some bad
luck with the job.

If I did it myself, I'd want to go slow and have the whole
procedure mapped out in my head before I started, and
maybe consult the shop first to see what they thought.

Best of luck.

 

There is no possibility of "extracting" a cantilevered steel stud
that's welded to a steel swingarm in the traditional manner that the
Japanese have been building
swingarms for the last 50 years.

He broke the threaded part of the stud off, leaving the larger
diameter unthreaded part of the stud in place. There is nothing that
can be done to the stud to repair it without making it weaker.


Forget extraction, there is no way a $tealer$hip would do anything
except replace the whole $360 swing arm, due to liability concerns.
