jsp Posted April 17, 2012 Author Report Share Posted April 17, 2012 which wheel has two different size bearings in Taff ? never changed front bearings whats the best way ? jsp Quote Link to comment Share on other sites More sharing options...
taff_d Posted April 17, 2012 Report Share Posted April 17, 2012 (edited) The rear has 2 different bearings, the 6004 is thicker but be carefull the thin 6905 bearing was also in a thin bush which came out as I drifted the bearing out, make sure you dont throw the bush away with the old bearing and refit the bush before you fit the new bearing. The front wheel bearing change is really easy, knock the inner sleeve between the bearings down then drift the bearings out, to refit I think it's a 32mm socket is the right diameter too knock the bearings in with. Some people flick the bearing covers out and repack the bearing with grease I've tried this but the bearings never lasted any longer so I don't think its worth the hassle. Front bearings can be changed easily within 1/2. Hope this helps. Thinking about it I reckon my rear hub was a Friday afternoon one ! it has a sleeve because if was machined over size and has had a repair done on it !

jsp Posted April 17, 2012 Author Report Share Posted April 17, 2012 sounds simple enough, ive always packed the new bearings with grease when ive done the back ones, and i also do it everytime i have the wheel out, but never changed the front ones. and i havent changed any on the ossa. order my new 6905 from ak, i had some 6004 in stock as there the same as most bikes jsp Quote Link to comment Share on other sites More sharing options...
furse Posted April 17, 2012 Report Share Posted April 17, 2012 I dont know if the wheels are different to the 2011 but Bill was machining them to take proper size bearings that will last. Quote Link to comment Share on other sites More sharing options...

taff_d Posted April 20, 2012 Report Share Posted April 20, 2012 Where do you guys ride , to have SO MUCH bearing problems ? In lots of water sections and then there is all the cleaning using chemicals and power washers. Quote Link to comment Share on other sites More sharing options...
toothandnail Posted April 21, 2012 Report Share Posted April 21, 2012 I ride prob 40% of the time in/around creeks , pressure wash(I make sure to avoid seals) EVERY time I clean it. That much bearing problems is amasing. Quote Link to comment Share on other sites More sharing options...
