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?
I know HighFive has messed with them. You could PM him directly for advice. http://advrider.com/index.php?threa...uestions-thread.850525/page-267#post-25460059
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
