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 The previous version was outdated and no longer supported.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

TE449 Front Sprocket loose

Performing some post-ride servicing and having removed the chain the front sprocket has some noticeable play - is that normal?

I changed the drivetrain about 200 miles ago (front and rear sprockets plus chain) so everythign is pretty new. Front sprocket is a steel Renthal and both sprockets are in good condition, no significant wear/hooking.

The 2 bolts holding the lock-washer to the sprocket are tight. The fitment is such that the sprocket slides on the shaft and the lock ring is slid on afterwards and rotated within the groove so that the "teeth" on the lock washer are misaligned with the splines to prevent it coming off, but that means that the only tension that can be applied to the sprocket will come from just those little teeth I can't tighten anything up to remove the looseness, all I could do is shim out the lock washer (or behind the sprocket) so that a little more pressure is applied when the 2 bolts are tightened.

Is that looseness normal, or something I should worry about?

Axial play: okay. Radial play: no good. (axial is side-to-side, radial would be fore-and-aft). from your description, it sounds good. I actually prefer that method of retention (or a giant e-clip which you could use too) as it allows the sprocket to float slightly.
 
Yeah Trenchy is right. I had the exact opposite problem with a SuperSprox up front. It was just a tad too thick to allow the lock ring to engage. I used the latest in redneck tech to fix the problem. 100 grit sandpaper and a nice flat surface. Rubbed the back side of the flange down little by little until it was just right.
