2010 cat 800 completely puzzled someone please help.

[Destroyer]

2010 crossfire 800 pclaw track

480 miles

Started vibrating, grinding, felt like the belt was slipping. more noticable at slower speeds in deep snow with rpms between 6500-7000

-primary clutch bushing was shot, so cat replaced the entire primary under warranty

-problem didn't go away

-took apart diamond drive, 6203 bear was in pieces, replaced, cleaned and re-assembled. I think they should replace the gears and other bearings, 4 balls were demolished in there somewhere.

PROBLEM IS STILL THERE!!! can anyone suggest anything?

sounds a little like the guy on here who's bolt on the brake rotor came loose and was grinding on the rotor????

Take the machine back to cat, still under warrenty isn't it?

It's there...we can't figure it out.

I can make the belt slip big time. I can make a a pretty thick black mark 2/3's up the primary if I ride it in the really grindy zone.

 

[diggerdown]

Sounds like you could have a broken primary spring.

 

[Destroyer]

Nope. Entire new primary...spring and all. Bushing was toast.

 

[diggerdown]

I don't know about the grinding noise without hearing it myself, but They should have replaced the planitary in the DD when the bearing went out. You know metal pieces were ground up in it and it will fail. 100% certain of that!

 

[Destroyer]

I wonder if it could be a crank bearing? it's not throwing any codes or anything like that.

 

[cfr800ho]

i would have dealer replace diamond drive. if the bearing failed and pieces ran through it its junk!!!! if dealer wont replace find new dealer that wont waster your riding time.

If the dealers best mechanices can not figure it out. Then tell them you want a new sled.

A friend of mine had a problem that the dealer could not figure out. The dealer ended up giving him a new sled. Granted the dealer was not real happy about it.

Problem is still there. The dealer has another 2010 doing the same thing. They can't figure it out. They asked us to write a symtoms letter to cat including the vin number. Something is up with the 2010's. They've been through my driveline with a fine tooth comb. It ran good for 460 miles. Crank?

My sled hasn't ran properly since Jan 28th. I can't take it out west like this.

Loud grinding, hard vibration, and lots of belt slip. Most distinct around 6000 rpm at slower speeds under load (deeper snow, uphill etc.)

check and make sure your helix has not sheered some of the screws or if their loose on the back of your secondary clutch.

 

[columbus]

check the driveshaft bearings on the brake side.

 

[kane13]

Maybe something with that track? Something destroyed that primary and bearing, i would check the crank runout now foresure then clutches for offset, parallelism. Dealer should be able to figure it out take it back its their baby now no good to you like that its brand new and its not up to you to send a letter to cat thats their responsibility, take it to another dealer.

 

[mmsports]

Secound that

This is the first place i would look and I think you dealer would also. Put a different secondary on if that does not fix it you probably have a driver tooth out of time or bent just a bit put new drivers in it if secondary is not the fix.

check and make sure your helix has not sheered some of the screws or if their loose on the back of your secondary clutch.

 

[Destroyer]

Tried a new secondary, Checked the brake side bearing. Inspected the drive shaft and drivers. Checked clutch offset. No helix bolts sheared off.

Track would be a wierd cause. Ran good for 460 miles

Vibration

I seen this were the Drivers just moved a little and caused a vibration. You can try that or just go get it ride the crap out of it until it breaks and the have it fixed.

exactly give it hell until it breaks then have it fixed, I wouldn't worry about it, thats what warranties are for . I am 100% sure I could get to the bottom of it

I got a chance to spend some time looking over my sled today. This is what I found.

I like to set my belt deflection so that the track slowly turns on it's own or is really easy to spin with one finger. I had it set, spinning it with one finger and then it hit a tight spot. Pushed through it, Spun it some more, and another tight spot. I thought it was in the belt so I shut the sled off and removed the belt.

I turned the track with the belt off, motor off of coarse. And low and behold there are two tight spots per revolution.

I inspected everywhere under the sled, and around the drivers looking for the track to be binding somewhere. It didn't appear to be binding anywhere. I still believe it's in the gear case. Or it's binding somewhere on the drivers that I can't see.

Any thoughts?
