Rear swing arm play

[donny1972]

Just had a good look around my 04 1200gs last night prior to mot and noticed a slight bit of play in the rear swing arm. Has anyone ever had this problem? I take it there must be a bearing that is gone.

Yes, it could be that the taper roller bearings need adjusting but more likely they need replacing due to wear as they are not a sealed bearing. Laser tools make a special adjusting tool or you can grind open a socket and use an Allen key.

Thanks for that puk. Is that the same tool as the swing arm removal tool.

The previous owner of my bike mush have killed mine with a water blaster so I had rusty balls. When I priced the BMW bearing I had to sit down. I looked it up in the SKF catalogue and there was no equivalent. So I just chose a sealed ball bearing race rather than the special taper roller from BMW. It worked fine and did another 25,000 on it ..... it was still doing fine when I sold the bike.

It's laser tools part 4740 and costs about £17.

New swing arm taper roller bearings are BMW part C33.17.2.311.729

The ones I have as spares are marked as:

FAG Z-539816.01.TR1. HUNGARY 18E (and are sealed on one side only).

You should be able to cross reference these at a bearing suppliers if you need to replace them and BMW are out of stock, probably cheaper too.

Try adjusting the bearings first before spending money as I bought new bearings for my old bike then found the existing bearings just needed a nip up.

What a shame grease nipples seem to be hinges of the past.
