Paralever Bearing.

[GedJack]

Just had the mighty GS in for its MOT. Passed with no advisories but he did comment on the fact that their was some slight play in the rear wheel bearing, not enough for an advisory.
He said it maybe Paralever bearings and if it was they can be tightened.
Any idea how folks ?

Should be lots of info on here if you do a search. First of all check if it really is the paralever bearings and not the FD bearing. Get someone to hold on the rear brake while you test for play. If it's still there, then most likely it is the paralever bearings.

You might get away with tightening/adjusting them, but I'd bet they're shagged and need replacing. How old is the bike?

Yes they can be adjusted/tightened.

Inner pinnion, loosen locknut and take up the play. You don't even have to remove the rear wheel. Use an extension and go through the spokes.

My Gs is still on the originals after 14 years and 75k miles simply by adjusting and greasing once in a while.

Bike is a 2002 model with 47,000 miles on it.

I'm a great believer in prevention rather than cure, so will try and adjust later.

How do you grease them Steptoe ?

If you're just trying for adjustment, then rear wheel off, some heat (well, quite a lot actually, with a hot air gun) on the inside lock nut to losen everything. Then judicious adjustment of the pin (12mm allen I think)and final re-locking with that big nut.

Don't attempt to force the nut or pin. If they don't turn, add more heat

ps. If you're into prevention, then really you need to take it all off, re-grease and keep checking/re-greasing thereafter. As per Mr Steptoe, who clearly knows how to look after them

Thanks for the advice,
Now to find a heat gun.

If you are careful, you can use a blow torch if you have one. Just be careful where you aim it so not to melt the rubber bellows or to take the paint off the swing arm.
