Replacing rear wheel bearings

[BribieDuc]

Thought I would try to do this myself.

Two questions:

DoIi need special tools to remove and replace the bearings - I see the workshop manual talks about drifts...I am thinking of using a punch for removal and a piece of metal tube the same diamter as the outer bearing ring to insert...will this work.

Types of bearings...I see from the board that 6005 is the go... do I get these from the duc dealer or is there a better source to get them... do they come in different grades?

Thanks.

Just read the recent thread re bearings... okay so SKF 6005 C3...where do I get these from in Brisbane...CBD or Northside would be best...

Type in SKF or Bearing suppliers on Yellow Pages or even a normal web search and you should get shops in your area! 

On the DS the hub bearings were the same front and rear wheel, but the sprocket carrier were different.

not sure about your wheels, but mine have a shoulder behind the bearing so you need a bearing puller to get them out, this consists of a slide hammer that threads onto an adapter that suits the inner diameter of your bearing with 4 vertical grooves and shoulders to grip the backside of the inner race. to reinstall them a press is best but plenty use a socket of the correct outside diameter with a little WD40 for lubricant. be careful to centre the bearing and knock it in evenly.

On my bike the rear spacers have a notch in them to allow a drift (or, if you're a backyard butcher like me, an old screwdriver) to hook up on the inner race to drift them out.

You can make a good bearing getterouterer by getting a large screwdriver, (The big one with the metal cap in the top. Its usually the 2nd largest in a Stanley kit with the yellow handle.)

And grind the end of the blade down until its about 2-3mm thick, and then grind a notch in one side around 4mm or so long and deep. And you have a long punch that will locate in the notches in the hubs so you can give a good solid whack to knock 'em out.

Tut, tut, tut, such terrible brutality, use a brass drift which is much softer than bearing races, its safer than tool steel on bearing steel, they tend to chip if struck wrongly.
Ande yes always, always go to a bearing shop for bearings, then for full satisfaction go to your ducati dealer and ask for the price of the same bearing through them, it will be much dearer

Good thing I started on this last night!

Got 2x6005 bearings and disassembled no problems.

Two issues:
Couldn't get the wheel bearings out with a drift ...  spent a few hours and different 'tools' without any joy.... so took the wheel to the dealer this morning to have them remove the bearings with a blind bearing remover. Will collect on my way home and finish the bearings tonight.

Didn't know there were bearings in the sprocket carrier and yes they are different (not that I had surplus wheel bearings anyway). This was where the problem was... shield was gone and the ball bearings easily bunched up on top of each other allowing the centre tube to move all over the place!! ..in fact cleaning the carrier and ball bearings everywhere! Picked up 2x6006 bearings for this this morning.

Learning heaps.

it may be too late now, but did you think about dropping the bearings at the shop and getting them to fit them using their press? it's safer and easier to get the correct fit using the correct tools, and for a few bucks in labour it's done with just reassembly to do.

All done - other than  removing the bearings it all went well. 

Used a large sprocket as a drift to insert the 6005 wheel bearings...was very careful all was centred and went in evenly.

Heated the sprocket carrier in the oven and froze the 6006 bearings as I was told...all went in easily.

On the road and it's surprising how quiet it now is - not just the clunks but there must have been a bit of continuous noise!.

Think I will put some spare bearings on the shelf and invest in a blind bearing puller for next time.

Thanks for the info and confidence to attack this task by myself.

To me its part of the adventure of owning and riding motorcycles. 

Unfortunately some bikes needed a LOT more work than others to keep mobile. BSA springs to mind. They got nicknamed "Bastard Stopped Again" and another mates Laverda (Lavatory!!)

Its very satisfying to do stuff to your bike and feel/see/hear the results and know that you did it.

Well done.    [moto]

good work john. i got my bearing puller from glenfords and it cost me about $150 or so, funnily enough, i've used it about three times and it's nearly always on loan to a mate or one of the guys at work.
