Hey guys I'm not trying to beat a dead horse here but I could'nt find it in my search. Do you have to machine the shaft to get the 5203 bearing in? Or does somebody have a link for the 11'? Thanks for the help

I did the same also on my 11 and it seemed fine although I have not checked it yet this year.

I replaced my 2010 6203 with a SKF 62032rs and all well so far. I just checked it.

Back off your track tension some and pull the DD. Lots easier to work on it on the bench because you can access the cover bolts easier and easily save the gasket instead of risking tearing it.

Remember, there are 2 pins built into the cover plate for alignment purposes and it helps to lift off the cover evenly on all sides.

The 11's I went through were the same as the 10's. I did machine the shafts and installed the 5203 bearings.

There are some of the boxes that will fit the wider bearing in them....but....is the carrier gear aligned with the driver gear and are the planets aligned with the sun gear on it....those are the measurements that need to be taken into consideration when deciding to machine the gear or leave it. Measure up first....saves you money in the long run.

I've put 5203 in 2 09's & one 11 and didn't machine anything. No issues, cover closed just fine.

I had mine machined (11 m8 HCR). Not sure if it was required or not. Wasn't going to take the risk. Had a local machinist do it for me. Was pretty cheap if I remember correctly. The bearing is obviously wider than the old bearing and washer.

Didn't have mine machined on 3, 2010 M's. Also, talked to a head mechanic at Arctic Cat in town and he said they do not need to be machined. If you want the extra piece of mind though, it wouldn't hurt.

I was told some will have a hard time closing without the machining... not sure if that's the proper way to tell or not, but mine closed easily, so I ran them.

The double row bearing (SKF 3203) went into my 2011 HCR DD just fine, with no machining required on the DD shafts. The DD cover closed with no problem and the DD output shaft still has 0.012" axial clearance.

My track drive shaft was too long for my tunnel by 0.130", so I had the drive shaft machined to match the tunnel, and installed the bearing shield. Here's the link:

Good Luck!
