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 The previous version was outdated and no longer supported.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

Replacing headset bearings

I'm somewhere north of 30K miles on my Terra and my headset bearings are notched pretty badly. Has anyone replaced theirs yet? I found this video of them being replaced on a GS650 and have to assume they would be the same.

I'm not the most mechanical person in the world but I'm also not an idiot. While it looks fairly straight forward I am slightly intimidated by pulling the entire front end apart. Is there anything I need to pay special attention to (bearing or fork removal). I figure if I'm going to go through all of this it might be time to also consider doing the fork swap. Is there any real danger of riding it notched until I can secure the new forks, i.e. can the bearings fail or lock up?

 
Be very conscious of the ignition switch and ring antenna. Remove your battery first thing. Take the time to remove and lube cables, if you try and just remove only what has to come apart, you end up taking longer than just removing things that need inspection and service anyway. Tag things if you need to.
 
SHB from the Brazilian post at Advrider - SKF (2x): RBT1B 329013 A/Q, Brazil

There is confusion re the SHB both at Advrider and at CH, in the parts interchange it is claimed to be 29x48 and a special bearing size

An SKF RBT1B 329013 A/Q is a standard bearing size and the Q indicates it is part of the international series for interchangeability

See this page at simply bearings

The ID and OD (29x50.2mm) is the standard size used by Husky on other models, and by KTM/Husaberg and others, it is actually an imperial bearing
BMW dont use that bearing size they stick to a couple of metric standard sizes
Inner Diameter d ( mm ) 29
Outer Diameter D ( mm ) 50.29
Thickness B ( mm ) 10.72
What is interesting is they are using a fibre cage and it is a lower height than the KTM bearing

KTM SHB
Tapered Roller Bearing Single Row - L45449/L45410
Inner Diameter d ( mm ) 29
Outer Diameter D ( mm ) 50.29
Thickness B ( mm ) 14.22

Manufacturers - NSK, Timken, MPN, NTN, Koyo, ZVL-ZKL, LYC

You would proably be able to use the more common KTM bearing but Timken are sure to make an equivalent anyway

Why is that, what could possibly go wrong?
