Rear Sprocket/drum replacement...

[hortoncode3]

SO, on my 2009 G5, the front AND rear sprocket is trashed. Got both, but now I'm told there's a rear wheel bearing that needs pressing out of the drum/sprocket. If I'm going to need to do that I suppose I'll need a new bearing, as it seems kinda stupid to not do it. This project seems to get more complicated by the minute, I was sweating pulling the side of the case off to change the FRONT sprocket, and then getting to together well enough to not make it a perpetual leaker. GAHHHH! Now I have to press out a bearing too? There are times I pine for the simplicity of a Jap bike..but then I look in on  "Winston" and smile!  I'm prepared to say screw it and send it to my fantastic dealer..Suggestions anyone?

They offer a kit where  you can replace the sprockets independant of the rear drum, but you have to buy a new rear drum to do it.  It might be worth it.

I may be wrong but I think that kit works only on the old iron barrels and maybe the AVL's?

The bearing in the drum is almost a wear item and should be replaced. It's a 6005-2RS/C3 bearing available at any bearing shop. There is a seal in there too and if you use a bearing with a rubber seal you can use the old seal.
Put the bearing in the freezer for an hour or so and heat the drum up with a heat gun and the bearing slips in pretty easy.
You'll need a new cover gasket when you replace the front sprocket.

You way overthinking the Enfield.

I find most of them are a PITA to work on. That's why most people take them to the shop for $100/hr.

Would you happen to know what the other two wheel bearings are?  I was thinking of replacing them while I was in there.

Sweet, thanks!  Is the seal a standard part too?

I did buy one at the bearing place but tossed the box without writing the # down in the back of my manual like I did with all the bearings.
It's kind of redundant with a sealed bearing though.

I just took the rear apart tonight.  It is a 6005 2RS C3, so rubber seals on both sides.  There was just the tiniest hair of the outer race visible so with a screwdriver and hammer I was able to remove it without destroying it.  It feels fine, smooth and clean, but I'm going to replace it anyhow.  It's a pain to get out, I can't get any fresh grease into it with the seals, and  I don't want to do it again any time soon.

The seal came out easily too.  I may reuse that.  There's also an o-ring in a groove on the inner side of the sprocket/drum.  It came out and is fine so I'll reuse that. 

I'd probably be more picky about the seals but this bearing is double sealed and the wheel bearings are sealed on at least one side from what I can see.  So I'm not too worried about it all.

i got the bearing locally for $15.26. got the original one out no problem the same method. just cheap insurance.

While it never hurts to replace a bearing..... we sell very few of them. In the old days they used to be open bearings that required greasing. In fact I imagine we still have a few. The irony is that none of these were ever imported to the US.

Kevin,

The bearing that came out felt just fine.  If it weren't sealed on two sides and I could get some fresh grease in I'd keep it, but for the $15 I paid for a new one this morning it's just cheap insurance so I don't need to take apart the whole rear end again any time soon.  Do it right once and forget about it

Although I preach it I rarely subscribe to the school of "if it ain't broke don't fix it". I would have done the same thing

[Ducati Scotty]

I was going to get the seal too, even though I said I'd probably keep the old one.  They didn't have the right size so now I will be reusing it.
