Title: Spool Install into Steel Swingarm
Post by: b. on October 08, 2009, 08:47:57 AM
I'm installing spools into my steel swingarm and having trouble with the threaded rivnut inserts that the spools screw into.  They keep spinning despite using the correct size drill bit...any suggestions on how to keep them from spinning so that they'll properly crush into the swingarm?

TIA.

I haven't heard of anyone doing this, you might get more replies if you take some pictures of what you're trying to do?

You need to crush them before you install the spool. They make a tool for that.

Try installing a bolt with a nut threaded on it of the proper size for your insert. It has to be long enough to pass all the way through the insert. You can use a washer if you're concerned about marring the swingarm while tightening the nut. Tighten the nut against the insert while holding the bolt stationary. That should 'squash' it. It will take some force so use long wrenches if you have them.

+1 I had to do this as well when I installed them on a couple bikes.

This is what I'm doing, except on a steel swingarm:  http://ducatimonsterforum.org/index.php?topic=1777.msg18999#msg18999 (http://ducatimonsterforum.org/index.php?topic=1777.msg18999#msg18999)

This is what I've been trying, but the rivnut keeps spinning in the hole that I drilled into the swingarm, which is preventing it from being "squashed."  Would it be bad to use some sort of cement to try and hold the rivnut?

Glue never worked for me.

You might try going to a local auto body shop. They should have the tool and might do it for a modest amount. You have the inserts, and it will only take a couple of minutes.

I put spools on my 600ss using the washer+nut+bolt and had no problem.   the trick is to hold the bolt head with one wrench while turning the nut.  you can't let the bolt turn at all. 

make sure the washer covers the rivet head completely and it acts as an anvil.

it only takes about a quarter turn before it starts to expand.  another quarter turn and you should be good.

i used red locktite on mine IN ADDITION to squashing it.  t'ain't goin' nowheres.

You could also try putting a nut on the end of the bolt on the inside of the swingarm...then tightening the bolt while holding that nut. You can access the inside of the swingarm by removing the axle and end-plate adjuster screw assemblies. I had to go this route on one of the spool instals I did. Pain in the ass but it worked.

It's too late already since it sounds like you've already got the hole in the swing arm, but I hope you got it far enough away from the axle plate that you can upgrade to fancy stuff later if you so desire.  :-\

The location clears the axle plates, but I don't really follow your thought... ???

This thing. Companies like Desmotimes sell fancier axle plates that are bigger than the stock plates and hence the spool needs to be farther away from the axle. Notice how in the pic with the spool measuring clearance the fork of the stand goes right over where the fancier plate would be? I didn't check clearances when I installed my and when I took the bike down from the stand, the stand made a nice big gouge in one of the plates.  :-\

Solution: I don't use my spools anymore.  Oh well. Luckily I got a stand that had both the spool and under arm attachments so I just flipped it over and didn't have to get a new stand or give up my fancy new, albeit now damaged, axle plates.

Yup, I've got the Corsair ones that are going on as well...precisely why the spools are so far forward.   [thumbsup]
