  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Corroded ? chain tension adjustment bolts question

Doing some maintenance over the winter, and addressing an issue i found last summer. It seems that the end of the adjustment bolt that is inside the swingarm is gobbed up, probably rusted. Googled it and found at least one mention of something similar, basically it was a tip to take these bolts out and coat them with anti seize before it becomes a problem. LOL, well I'm past that point i think. Both bolts move freely in and out , but only out so far before they get tight. I don't want to keep turning them and damage the aluminum swingarm. Thinking someone on here may have a tip. ? I have a couple ideas, One is to cut the head of the bolt off , cut a slot in the end and then run them on into the swingarm and let them rattle around forever. Replacing them with new ones from the outside. the other idea is to go ahead and wrench them out or drill them out and then tap the hole for a larger bolt. Anybody got any " more smarter" ideas?
Thanks, Dan
 
It is a common issue. I broke one off, had to drill it out and re-tap the thread. If you do run them in you could get them out next time you have the swingarm off.
Instead of replacing with more of the same I got anodized alloy from the bolt shop and applied anti-seize too.
You may be able to find an adjuster kit with axle blocks for that bike, check 7602 Racing, maybe ZipTy.

:cheers:
 
if you have access to a propane torch, heat the aluminum where the threads are, and spray a good heat resistant penetrant on there..work the bolt in and out and with it good and hot, they should come out.
greasing these bolts is pretty standard on all bikes..not just a hoosk problem
 
thanks for the replies / advice. First bike with this type of adjusters, the old kawi has "snail" type adjusters.

While i was away,I drilled .125 holes on the underside of the swingarm where the bolts comes through. Sprayed a bunch of Kano-Kroil up in on that side of the bolt and worked it in and out some. Plan to do this a few more times over the next few days, and see if i can work it out. The Kano-Kroil has worked wonders for me before on rusted parts.

If that doesn't work, mix diesel and ATF in a 50/50 ratio, and use as penetrating oil. Hopefully the Kroil will work.
 
I got them out ! Kroil, perseverance and patience did the trick. Ran them in and out and sprayed inside the holes i drilled a few times each day. Never twisting the bolt toooo hard. The gummed up threads on the bolts pulled some aluminum out with them, but I ran an 8mm tap down and cleaned everything up. The bolts go in and out pretty welll now. Planning on putting new ones in there, possibly stainless. Also plan to pull them out occasionally and check and lube/anitisieze them up . Now to look up how to press out swing arm pivot bearings..I've got the swingarm off and the needle bearings on one side are pretty cruddy. Thanks, for the help guys.
 
One of my bolts broke as well, ended up welding a nut to what was left of the broken stud, come out easy.
Then re tap and plenty of anti seize.
