If you do go with a place for bearings prepare to pay the extra markup..[ie: $5.00 - 15.00 online bearing being $15-25.00 each at most local shops.]ok i measure mine when i get off work thanks for the help, i googled 6904RZ but will take off bearings and measure them too, found a couple of bearing shops here
Especially SKF brand
Ceramic bearings....LOL..[I wonder what they'd cost at a retailer...!]
I once took all the crankcase bearings from inside a Kawasaki 450 4 stroker to a bearing shop because I wanted to finish the rebuild in the same weekend...They wanted $202.00 less sales tax for all...I waited an extra day and got an OEM Kawasaki crankcase bearing set online for $80.00 flat...…..
With all the bearings in a two speed transmission the price you'll pay would be slightly lower than buying a whole new trans unit when paying the markup prices.....LOL
Its pretty easy using your cellphone to take a pic of the bearing then expanding the picture to get the right bearing # from off the bearing case or using a digital caliper to do an actual measurement of them but having the # is faster to find...
Its a lot cheaper getting them from places like ebay or amazon too.....
When it comes to choosing I always go with the rubber shielded deep groove design as the deeper groove design handles the sideloads exerted on them a lot better aswell as keeps the bearing better centered while the rubber shielding keeps out dust and water.\
