Dave's Favorite Bearing: The Main Bearing on the Drive Side on Vintage BSA and Triumph Twins

CN, C2 and C3 bearings are all under the same part number (70-2879 for Triumph and 68-0625 for the BSA CN bearing). Dave talks us through the different bearings, their history and how to distinguish them. (With special appearances from our old friends Stacy and Jürgen!) Check it out for some vintage Brit bike info.

Really good info! Any thoughts on bearings that work loose in the drive side crankcase? I heard the suggestion that too thick oil will work like a wedge, enlarging the bearing outer race, and thus the bore for the drive side bearing?

Hey guys where can I get that shirt with the triumph on the pocket? Kinda wish you had examples there.

Dave has actually had this one for 20+ years so we're not sure where you can find them anymore.
