If you like that one, you should have seen how we checked his rear wheel bearings and found they had come apart.
That was a real classic.
All the parts were sourced locally, cups, bearings, races, etc... all cheap and good quality name brands, if you buy bearings or cups from BMW you are going to go broke! The complete change out of the cups and bearings and all was done for under $100.

Less work to just grease them - you only have to go as far as removing the headset then cleaning the bearings, applying new grease and re-assembling.
One of these can make the job easier:
http://www.walmart.com/ip/Plews-Grea...-2In./15838252
It snaps on the end of the grease gun and lets you inject grease into the roller cage filling most of the cavities...


Some folks have commented that the factory grease job is light on grease, I had mine apart a while back and it seemed adequate.

If you ever submerge the bike I would do that at the next opportunity, otherwise not very often...
Just an opinion but maybe every 25K - 50K miles depending on how hard you are pounding the front end?

Saved you the trouble. I just finished doing two bikes this week - my wife's F650GS first, then my F800GS.

I took this picture of my 2009 F800GS steering stem while it was off the bike, to show the holes.



And this picture is of the tool I made to knock the bearing off from below. Took me two minutes to pop the bearing off this way.



I bought the drill bit in the picture and cut the flutes off it, and it did the trick perfectly.

The size of pipe needed to put the lower bearing back on the stem is the diameter you find on chain link fence top rail tube. Just so you know... I happened to have a spare piece of top rail tube so cut one to fit.

Also, if you put the bearing cups into a freezer for a couple of hours before putting them into the frame, they'll go in much easier. The cold makes them a little smaller.

Why does the parts fiche only show 1 set of bearings?

In this pic, the manual says to do this:



Which will save wrecking the cup washer dust cap thingy.

For what it's worth.

edit: that's a 4mm dia hole in the bottom clamp that allows you to use a drift, heat the bearing and just tap it off.


An easy/alternate way to shift the outer bearing ring from inside the head stem is to run a light bead of weld around the inside of the outer bearing shell. It will shrink when it cools and fall out.

Edit 2: Embeedee got to it between me thinking about it, and me writing about it. Oops.

To give you an idea, with nothing but trail riding on the DR650 I do it once a year...so every 10~15,000kms or so. It gets a work out, and the bearings get wet with the high pressure washer. I do all the wheel bearings, swing arm pivot, linkage etc at the same time.

The BMW has 40,000 kms on it in the last year and I'm about to do it. I'm prepared to let it go longer because the bearings were replaced when I bought it, and it's not had the high pressure washer near the steering bearings. I'll do the wheels, swing arm pivot etc all at the same time.

It's maybe a 20~30 minute job for the steering head. Jack it up, remove the top triple, drop the lower triple enough to get grease in by lifting the bike on the jack, grease the bottom, drop the jack, grease the top, back together. I don't plan on removing the bars.

Unless it's full of dirt I don't plan washing them out. Just work the new grease into them. If it's full of dirt, out comes the tin of degreaser...liberal use...wipe it clean...pack with grease.

A hell of a lot easier than changing the sparkplugs.

Stephen, it's because they are both the same. Don't buy them from the BMW dealer, source the parts at a local bearing shop. You'll pay less and get far better quality.

It's odd indeed only showing one set. I've ordered a set of SKF bearings, 21 each. Got them as spares. Mine were tightened a while back so they're good for the time being.

I don't know the SKF number but this is the Koyo brand.

The parts fiches says: 28X52X16
So that's 28mm ID, 52mm OD, 16mm thick tapered roller bearing

I've not had to replace mine yet, but a buddy did and NAPA p/n: BR32 (mfg. by SKF) did the trick for him.

I found them using this code. But you can search via the size 52x28x16

What grease did you use? Is it a lithium grease?
