Well got a helpful tip from someone on a good replacement bearing. So I went and picked them up. Much beefier than stock and slid right in. Best part about them is they can be picked up at your local napa. Bearings are about $30 a piece and seals were like $35 for both. I got mine back together tonight and it was pretty straight forward. Took about 45min total to tear down and put back together. Here is the brand and part number.

Bearings
Brand SKF
part # 32008-x You will need two.

Seals
Brand SKF
part number 19832 and 20430

Im pretty sure the first number is for the drive side. Might wanna double check when you buy. I think this will be a perminant fix. Mods might wanna sticky this if everyone agrees.

Thanks, great info!

Good info on the seal numbers, but I had to replace the left bearing on the '08 Fourwerx 540 xc yesterday and that was the bearing that was in it already. SKF brand 32008x Maybe not all of these came with the same brand bearing?

Mine went out on my 505 already. Are the stock ones known for going out pretty quick? Under ten hours on my bike. haha

I had play in mine up to about 10hrs, I would have to tighten every ride until they "set" in, now I've checked and they don't seem to need any more adjustment.

Did you overtighten them?

mine fell out after about 4 miles...haha it was only because my axle nut was loose! so now I get new bearings and sprocket!!

I think the previous owner over-greased them.

mine are out and i was going to pick some up tomorrow and want to make sure i was getting the right stuff, i looked up the part numbers on NAPA Online and here's what i found. Are these the correct things? Thanks

yup just install the sprocket side seal backwards so the grease can excape when it is full otherwise you will push a seal out.

 

[Higgerson#665]

is this true? that wouldnt look right to me, that would put the "hollow" side out wouldnt it? i just opened up the seals i bought and even tho they are diff part numbers they are exactly the same??

 

[DirtyMaxDiesel]

Yea I noticed that too, exact same seal on both sides with different part numbers, so I put the old seal back in on the chain side.

 

[Oloof]

Oh yes, Swedish bearings is the shit

Ya the hollow side would be out. The factory seal on the sprocket side is reverse of normal, it allows grease to exit with out blowing the seal out of the housing. The Napa seals are very similar to each other but they are different. I tried the Napa seals and after blowing it out with grease I went ahead and ordered the OEM seals from KTM and they were cheaper than the Napa seals.

These work on the XC as well?

Ya the carriers are the same between both quads.

how often are you supposed to re-torque the bearings?

how often are you supposed to re-torque the bearings?

And by how much torque ?


Just pulled out my bearings, and they were exactly the same as driver listed. Don't know if it changed between 2009 and 2010?

Anyone?? - Come on guys!

 

[AZ450XC]

Anyone?? - Come on guys!

Are you talking about the torque on the 47 mm axle nut that puts pre-load on the bearings?

If so 18.44 Ft lbs
