RG150 - How to remove Sprocket Housing bearing?

[riffer]

Hey y'all.

Picked up this RG150 for a fellow KBer yesterday. I've pulled the rear wheel off - its failed it's warrant due to excessive wear on the rear brake rotor which I've discovered is caused by excessive wear and play in the sprocket housing, making it impossible to do the axle up tight enough.

So, I've flicked the outer seal off - and it's rusted to shit. And loose as buggery - about 2 mm play either side. Removed the internal spacer, but as for getting the sprocket housing bearing out - I'm not sure.

Is it a press fit? And I can just bash it out? Or is there something I'm not aware of?

I don't want to wreck this housing as it ain't my bike.

SpraY a liberal load of CRC around the outside of the bearng. Walk away till tomorrow--Tomorrow am -more CRC. Tomorrow night bash the shit outa it with a hammer and drift. If that doesnt work --Get a bigger hammer--if that doesnt work repeat step 2
Or of course being a sprocket carrier--ie fairly easilly moved enlisting the help of someone with a hydraulic press and the right sized pusher would be a better idea
I hope the new owner is bloody thankfull --actually Ill remind him of the effort people are going to for him

CRC + Hammer + punch. Get at it from the other side and tap it out evenly.

I would clean up the rust a little, where the bearing has to slide past, soak in CRC and tap it out from the other side, I would n't use too much force as the housing is probably cast ally and won't like the shock. Lay it on timber or a sheet of insertion rubber so you don't burr the bearing housing.

When you fit the new bearing make sure housing is clean, throw the new bearing in the freezer for a few hours, and with a light wipe of oil tap it in - use a drift/dolly just under the outside dia of the bearing so you only tap on the outer bearing race.

Hope this helps.

Awesome advice guys. Kind of what I figured, but you know how it is when it's someone else's bike. You don't want to fuck it up.

Warm the alloy just before bashing the bearing out. The oven is good for this. Wait till the wife goes out and set it to about 100°C.

Good advice. Burt Munroe would've done a batch of scones at the same time. Alloy, cheese and onion. Yummy

Actually he would have conned some dolly bird into making the scones for him while he fixed the wheel... Then enlarged the engine with the time he had saved by not making the scones..

So true. I have much to learn Obi Wan.

Give it to Str8jacket to ride, it'll blow apart in no time !

It's very common for the spacer to be fitted around the wrong way. I've seen plenty, road and race, continue on for a while like this. But it stuffs everything internally. The bevel goes toward the centre of the bike.
If you really get stuck I have heaps of spare carriers complete here. $30plus p&p

The CRC did the trick. Four bangs and the sucker is out.

Thanks for that advice oyster.

The bevel edge was indeed pointing towards the inside.

I just don't think it's ever seen any grease since it left Thailand 11 years ago.

If indeed it ever had any in it.

Parts ordered. Should be ready for the road test by Saturday arvo.

You dont have any rear disks in yer boxa tricks do ya?

Nice new bearing installed today (sealed one this time).

There was so much play in the old one it wasn't funny.

Back brakes rebuilt and work nicely now.

Now on to the next problem. It won't rev over 8K under load.

Charged the battery; it hasn't made a damn bit of difference.

I've got a spare spark plug; I'll try that first.

But I'm thinking that the petrol may have some water in it.
Or the carb's dirty.
Or the AETC valve is stuck on low rev mode.


Anyone got any other ideas?
