2009-2011 Diamond Drive Bearing Failure

[silverram323]

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

Rick, I'm not sure. I called BDX and he told me to try and put the cover on and if it don't fit, that means the planetary moved when the cover came off. He told me to loosen the 16mm bolt a ways, bolt on the cover and tighten the 16mm bolt back up.

BDX, can you explain this?

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?

yes, mine looks the same. looks like the bolt on the top back mount is bent forward. i gues that this is normal. anyone that has a mount that looks straigt?
i have a -09 cf1000.


don´t get why the new bearing i thicker then the old one including the spacer. and how it´s working to have bouth kinds of them in ther.
the new one shoud either be to thick for closing the casing. or more likely. the old one does not make the bearing on the outside of the lower gear sitt al the way out to the bottom of the outer casing. in that case you move the lower gear 1.5mm outwards whit the new bearing. is this a optimum thing to do?
the gears might line upp less then perfekt.
or am i wrong? what holds the lower gear i latheral position?

Your right...the new bearing has to move the gear out 1.5mm. I replaced my stock gear with a BDX gear that has holes in it and I can see that the gear does not line up flush with the planetary gears. You cannot see this with the stock gear. Does this cause problems...I have know idea...I hope not. Maybe that's why Cat went with the smaller bearing to start with?

The small bearing and spacer allows that 1.5mm of gear shaft to stick down into that hole in the planetary you see in the pics so the bearing on the outside of the gear must not seat all the way into the cover?

This bearing does work on 2010's I was able to get my cover on.

Here's a pic with the double row installed on my 2010 HRC. You can see how the transfer gear rides higher in the planetary. I don't know if this will cause an explosion in the future so I still have the stock bearing in... Maybe some gear experts can chime in......

 

[mr p-j]

i still don´t get it!
if it is possible to fit a 1.5 mm thicker bearing then stock then the gear must have a latteral play between the outer casing and the planetoid ring gear of atleast 1.5 mm stock since ther is nothing to hold the gear in place exept the outer casing on one side and the planetoid ring gear on the other side.
the way that i understand is that the planetoid ring gear is beeing hold against the inner casing by the 16mm bolt inside the drive shaft. right or wrong?

if that is the case then the bottom gear can move about for atleast 1.5 mm whit the stock bearing. that cant be right now can it? please tell me i´m wrong! am i missing something?

Does Cat offer this wider bearing?
Anyone have the part number?

I guess we have to decide whats worse. The gear moving or not lining up completely. I would think the gear moving would be worse but I don't know enough about transmissions or gears to make that call.

I just received the bearing from Cat. It is Part #2602-108 bearing,transfer gear-17mm-peer. I will be installing it later today.

Cat knows of the issue then.
I'm going thru my dad's 2007 Z1 that has 5200 miles.
The plan is to replace all bearings and seals.
When I picked up the parts they replaced the bearing with a 2602-108,

Man O Man - Some of you guys are taking this way way way to deep - Replace the single row bearing and bee happy that you did - And to think i went the opposite way last fall because of BDX and there bearing kits - Me personally , as i always have , i would take the complete DD Gearbox Out of the sled , clean everything up proper , put it back together , and make sure everything moves nice and free without any resistance , all things are looked over , but thats just me

Read my story on HCS - 2006 Crossfire

Yes , i found out the hardway with that sealed single row bearing last winter - BDX started putting that sealed bearing and spacer in there bearing kits , even for the 05/06sleds that left the factory with the wider double row sealed bearing - Why , i have no ****ing idea other then cost , will get back to that in a minute

Well i replaced all my bearings in my 06 Crossfire DD for preventive maint last fall , using the BDX bearing kit

Well after about 500 miles my sled started making a grinding noise - It would come and go

Finally after one trip in da U.P. , i got home and ripped into my freshly rebuilt DD Gearbox - That single row bearing was toast (And when it came apart all the ball bearings took out my planetary gears) - In a nutshell my gearbox was toast - I had to order the correct double row sealed bearing from Arctic Cat (That the sled initially left the factory to begin with along with a new planetary gear setup ) Man i was ****ing pissed

So i called BDX Extreme and blasted them on the phone - They stated that the newer Cat Sleds were leaving the factory with that single row bearing and spacer and thats why they switched it over in there kits , even for the 05/06 sleds - They also stated i was not the first to have issues last year and they apoligized (Mostly guys sidehilling or something to that effect they said, putting more strain on that bearing ) - They offered to take care of me on my NEXT Purchase and said i should of called them first before ordering the parts from my dealer , but in the end , they said it would bee the last of that single row sealed bearing in there kits

I have pictures somewere along with a thread i started last year on the subject - ****ing Cat and BDX just trying to save a buck or two - Maybe they figured the newer bearing was lighter also , save a few ounces HA HA HA

****ers costed me a few hundred bucks because i replaced a bearing that probably didnt need to bee replaced in the first place , with even a cheaper bearing and spacer that took out my whole DD Gearbox

What is the difference between the Arctic Cat wide bearing, and the BDX wide bearing? One better than the other?

 

[CatAttack]

Question for you guys, I have ordered new gears ( 56-64) for my 09 M1000, will these gears come with the new double wide bearing or not? Oh yeah sled does have reverse

 

[1080paul]

No...you will have to put bearings on them.

Has anyone had problems with stripping the threads out that the cover bolts thread into?
I had two strip out when I torqued them to the repair manual specs which is 12.5 ft lbs. After that I stopped and just torqued to what I thought was tight enough

Yea I stripped one too, although I attribute that to the fact that my torque wrench goes from 5 to 100 lbs. Not exactly in the prime range if your using a cheaper torque wrench. I hope it doesn't leak.

X2. The bottom left bolt never really tighten up.

I went to install the bearing that I got from Cat, #2602-108. That is the part number that Cat is replacing the bearing in question with and it is not the wide bearing. I ended up going to a local bearing shop and got a 5203 which is the correct wide bearing. The bearing that I replaced looked fine, but I thought I might as well replace it since I was in there.

 

[aktreekiller]

hey

I'm having a local dealer do a pre-season check, including changing dd oil, and they told me they would replace the bad bearing before I even brought the sled in. They couldn't believe arctic cat isn't doing it yet.

Where were you told this?

I don't ever get squat out of the dealers up here. Dealt with Anchorage, Wasilla, and Big Lake.
At this point I've resorted to doing everything myself unless I have a major warranty issue.
