  • 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 The previous version was outdated and no longer supported.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!

Excessive Sprocket Wear

Husqvarna
AA Class
I replaced my sprocket due to excessive wear, and after 2 rides it looks like the sprocket is excessively wearing on the inside of the sprocket. (original sprocket pictured)
I have confirmed that the wheel is centered (used a ruler), swing arm has no play in it. I have yet to confirm that the sprockets are aligned, that will be next. My rear suspension really sags, I am having it re-done by Lt-racing, not sure if this could play into excessive wear.P1010914.JPGP1010913.JPG

The really odd thing is the wear on the sprocket isn't even around the sprocket? I spun my tire and used a straight edge against the rear disc brake and there is a very slight gap between the straight edge and the brake and I am curious if my wheel is not True? Would this cause the sprocket to wear?
 
All that side wear looks really strange ... I don't see how sag can cause that but it appears something is out of line back there ...

That brake disk may or may not be the best place to check for warping ... Unless someone give you something more specific, I'd keep measuring back there and looking for something out of alignment ....

How old is this bike?
 
It may be that your chain is too tight. I use 2 fat fingers at the end of the top chain slide as my ready reckoner for chain slack.
 
Are you sure the sprocket is mounted flush against the hub at all mounting points? And if that is a new sprocket, the teeth look like they are already cupped out to a bad degree and not going to last too much longer ... Did you use the old chain or a new chain?
 
as said it is probably the rear chain guard is not flush or is bent.perhaps a brp chain guide will help.dan
 
Thanks for the feedback everyone, I installed a BRP chain guide 2 trips ago, looks straight to me and with a new sprocket that is showing signs of excessive wear already. The guidance I received from a friend of mine is that the hub may be bent. I am going to put the swing arm back on this weekend and try spinning the wheel and check if the tire is true.
