Front wheel bearings

Post by Fireypete »

Hello all,
The front wheel on the sport turned smoothly, anyway I removed it for new tyres. I noted the axle does not turn the bearings, sticking a finger in (as ya do) and I couldn't turn them. Stuffed I think. So how to remove? Has anyone used the workshop manual method of using a drift in the inner race and belting them out, should I seek a press?I gather you hit one side and the opposite bearing comes out,then put the drift through the wheel and push the 1st set out... replacement number if you know it...I can search for that😉

There is a spacer tube that sits between the inner bearing races that the axle goes thru , you have to knock this over to one side to expose the inner race of bearing and then gently beat the shit out of it :P , tap it out evenly round the inner race so that the bearing comes out pretty square . You can tap on the inner race because you are fitting new bearings , normally tapping on inner race would damage bearing , if you cock the bearing it will deform the bearing seat in the wheel .....same deal when fitting new .... keep it square but only tap on the outer race , best idea is to get a socket the same size as the outer race and use that as a drift ( there will be vids on YT showing how to do this ). Dont forget to put the spacer tube back in.
I dunno the size but if you take the old one to any bearing shop Id be surprised if they didnt have them on the shelf ........at 1/4 the price of Ducati parts > :)
I wish I was young again............Id be heaps smarter than last time
