Next Question! 500 Sprocket Carrier

[philward]

I'm trying to take the sprocket carrier out of the hub but its stuck fast. I've put the old sprocket on the carrier and tried to drift it out by using a bar through the spokes (not removed the old spokes/rim so I have a more stable platform to hold onto while trying to get carrier out). Bearing and holder removed already.
Am I missing something as it is struck fast - its not flexing as if its just stuck on the cush drive rubbers.

You have unscrewed the LH thread retainer havent you?

[philward]

Yep, thats out Bryan. Its solid with no 'bounce' if it was stuck on the rubber cush drive - its a metalic feeling through the bar as I shock the sprocket.

[Bryanj]

They can get incredibly stuck on the rubbers and also on the big O ring thats D shaped, dont damage that one i have run out of NOS ones

I did not disassembly mine, but I've read that a lot of heat (propane) helps. There are also some videos on YT too I was told.
I tired, but gave up as it was not absolutely necessary

[philward]

I think it may stay in the hub!

It needs to come out to be greased. If not kept greased they do wear out and very hard to find a good one

I'll get the lump hammer out in the morning!

Not sure I understand - grease what? That rubber dumper or bearings? If bearings are worn, yes you have to take it apart, but otherwise?

[philward]

Bearings are out Erny - don't need to take sprocket carrier off for bearings, just the retainer (which came out reasonbly easily - suprisingly!)

[Erny]

Exactly and that's why I'm wondering what to grease then?

[philward]

Over to you Graham!

[Trigger]

This part needs fresh grease on it all the time or it will get damaged

Then I should take it apart during winter
Thanks for advice!

There's also a flip side to this if it's seized,  it will give a very hard time to the primary drive system inside the engine and particularly the chain. 

Relates to your other thread about engine noise Erny.
