2009-2011 Diamond Drive Bearing Failure

[smoking_powerstroke]

Here you go, but if you just want the one bearing you will have to call them.

Those are the wider or upgraded bearings??

 

[thump426er]

Wow, why is it I can't find this bearing cheaper than $40???? The only one in the $20 or under bracket is made in china,,,, and that ain't going in my sled if I have a say. Not a big deal as I'm willing to pay to have N. American made (or European if it comes to it) but I'm guessing the ones out there that people are quoting the lower price on are the chinese ones made out of recycled cardboard, dog bones, and 10-speed parts.

I would just give them a call. Whoever answers the phone will be able to help you.

Contact Freeagent. She's selling the double row bearings for $12.

Mine fit perfectly.

Here's a couple of pics with the 2010 stock bearing/spacer and the double row. You can see that the double row is wider. This is what i think is causing the problem with the 2010 case closing.

Im not at all familuar with the 2010, so help me out.
Is the stock bearing on the 2010 a single row bearing? if so has cat tried to make a larger internal ball or more balls in this stock bearing to cure the 2009 failure? rather than just going with a double row bearing from the factory. looking at your mic, looks like about 55 thousanths difference between the two bearing. Maybe cat figures the 2010 stock bearing is heavier than the 09 and will last. what do you think?

Here is a pic of both bearings on a set of BDX gears. I'm curious to see why the bearing doesn't fit a 2010.

I put over 2000 Miles on my 2009 last year, I geared down to M8 Gears as soon as I bought it, I had the Dealer do it, Decided to go back to the Stock Gears at the end of the year Last Year, Had the dealer change it back, He did not say anything about any problems. Not Saying this is a bad idea, but I never had any problems.

The 2010 spacer is thiner than the 2009 spacer. The stock bearing actually rides down on the gear further and the end of the gear rises through and above instead of flush (stock 2010 bearing/spacer). I'll post some more pics as soon as I can.

This is just an FYI but I checked with 2 dealers near me and both said the only way they have heard about this is from a few people phoning in to ask, pressuming they read this thread maybe??? Both dealers also stated, similar to rsp111 above, they haven't had any issues to date with the 09 bearing which includes no bearing failures on any RnR's done and they both mentioned there were several high mileage sleds come through.

That being said, both also mentioned it wouldn't hurt to stick the bigger bearing in but that they are not doing the change.

Here is a pic of the two bearings side by side. Notice how the stock 2010 bearing (right) sits lower on the gear. I think this is what's keeping the case from closing completely.

so how does the case wher the bearing sitts look like? ar ther perhapse a loose shim in ther that can be removed?
i doubt that cat will redesign the casing from one year to another just to fit a thiner bearing.


edit: or is the -09 intended to use some sort of gasket between the cases and the -10 just put the casing together whitout a gasket?

Good point..... It would make sense that there could be shims do to the spacer being thiner. It appeared to be solid case but I dont have it apart to check. Maybe this weekend I'll give it another shot. I do remember cleaning the oil out of the case where the bearing goes and it felt solid so I don't think there's shims but I could be wrong...

In for later

Here you go guys. I took pics and installed the new bearing from bdx.

I started by taking the belt off the secondary then pull the secondary off. I then took off the bracket bolted to the foot board. That was in the way from the DD gear cover to pull straight off.

Then i took all the T-30 torx bolts out. I think 13 total.

then i gently pulled the cover off as to not tear the gasket.

then brought the cover to the work bench.

Then i pulled the lower gear off.

I used a pitman arm puller ($15 at napa) to get the 6203 bearing off. I had to stack a 5/32 socket on the gear for clearance.

I put the pitman arm puller in the vise and pulled the 6203 bearing off.

6203 bearing thickness.

5203 bearing

Difference.

So i took the old bearing (6203) and the shims off and pressed on the new bearing (5203) till it seated all the way down.

My cover wouldn't snug up tight so i had to loosen the 16 MM bolt inside the shaft of the brake rotor.

I then Taped on the cover and bolted it all back up. the two bottom bolts are a PITA. I used the wrench from my cat ATV to do the bottom bolts.

Tipped it on its side to fill it up.

Put the secondary clutch back on, slide the belt on and your done.
If i didn't have to take pictures i could have done it in 20 minutes.

 

[silverram323]

I noticed the motor mount on top looks kind of funny, its tight and just looks bent or something. Not centered like the other. Does your guys look this way also?

 

[1M800]

Wow! Thanks for all the pics! Can't wait to change mine! Yeah right. I still think this sucks that we have to do this to our basically new sleds. What a joke!

 

[Desperado]

Thanks for the info, this was for your 10 right? The 09 bearing and spacer are the same width as the new wide bearing from BDX so there shouldn't be a need to loosen those 16mm bolts? Hope I understand this correctly.

I have a 09 XF8

Thanks for all the photos,that will let everyone see what they are getting into. its not hard.
My question for you is, by loosening the 16mm bolt thru the brake side, explain what all happened when loosening the bolt. Did it let the planetary move 150 thousandths for clearance? I never had to do that so Im curious
what happened. Thanks for adding to the post. RickM
