09 146x, 2 belts 150 miles

Double L · Nov 24, 2008

So i took my sled out for its maiden voyage last week and it ran great. I was riding between 1500-2500 feet and pulling 7900 on the hills with 2 feet of dry powder on a good base. The belt had 30 miles of trail riding before getting to hills and opening it up. Was planning on changing the clickers to from 3 to 4 but decided to get another ride in before messing with it. 2nd ride sled was pulling 8100 rpms but started to vibrate bad towards the end of the day. The belts grenaided at 103.1 miles. Put the new belt and went straight to the trail and rode out 12 miles. Got home checked the deflection and it was good. Went to dealership to get a new belt and ask questions. They told me it could have been an old 377 belt, WTF does that mean? I was also told it could be the clutches out of alignment but to ride it one more time before bringing it in. 3rd ride I babied the sled, after 5-10 minutes of playing I would open up the side pannel and let the clutches cool down. 30 miles into this belt it started vibrated agian and I noticed the cords coming out of the belt. 25 miles of trail and 5 miles of playing in some descent powder. Brought it into the shop this morning and we'll see what they come up with. Has anyone else gone thru belts this fast on their 09's yet. Has anyone heard of "and old 377 belt". Thanks fellas

I think Doo had the 377 in the 08 xp's ,but they changed to a different size. I'm not sure but someone on here will know fo sho.

First things first CLEAN THE CLUTCHES. TRA clutches have a tendency within the first few hundred miles to have sticky arms. Pull the arms out and use a srewdriver or something else round like that wrapped in sand paper and clean the indside of the arms and rollers. Next look at gearing down the xps come geared too tall out of the box. Gearing down will defenetly save some belts. The biggest thing though is to really keep your clutches clean. I have not even pulled a thread in my belt for over a season and I'm a big guy(230) and I ride hard. Ski-doo's get a bad wrap for being bad on belts but if a guy makes sure his clutches are clean and to break belts in they actually are not that bad.

Dude, 2 belts in 150 miles is brutal! I can't believe 09's are having the same issues as the 08's. Last year I had the same probs with belts. I cleaned clutches, belts and took er easy but to no avail. Hopefully the dj's kit I just put in will make it better. Don't believe the "old 377" belt bs either. Sounds like something AMDS would tell you. (Am I right?) Why would an 09 have an old 377 in it? Let us know what it was once you get it figured out. Good luck

I would guess your dealing isn't perfect and is getting the "old" 166 story and new color 166 confused. Tell him that 377's aren't old they came out in January.

2 Belts sucks!!!!

What i find even more interesting is a lot of guys have run to the dealers asking for all the new 09 clutching and it is not even proven. It sounds like the 09's are junk as well as far as clutching goes. I took my 08 in to get all the updates done and they had all the 09 clutch part numbers on one of my invoices.

They couldn't believe me when i told them i didn't want it. This is a perfect example of how BRP makes money off the backs of its customers.

There are countless threads on the 09's already amongst the major forums. BRP needs to fire Team and go back to original Quebec based clutch part manufacturer and pay the little extra and get something better for its customers. BRP can you hear me ????

This sounds like 2001/2002/2003 no ? I bet 2010-2012 will be the bomb !!

turbo al you need a job?

Double L · Nov 25, 2008

Just got off the phone with the service department(yes AMDS) and my sled is next in line. They are convinced the clutches are out of alignment, a couple other 09's have had the same problem he told me. They are going to do there best to get it done before they close tonight so I can go riding tomorrow. Rumor on the street is there is chest deep snow up north which means knee deep snow but I still don't want to miss it. I let you guys know how it goes. Has anyone or is anyone planning on regearing their 146's? I've read about a lot of the 154 guys going to a 20t or 19t and it sounds like it helps. Thanks

There is an article in the new snowtech mag about the new doo belts. 2 new belts replace the 166 found on xp's last year.
383 is the same compound, but 1.5mm wider, same length. Recommended for trail sleds
377 is a harder compound than the 166/383, is 1.5mm wider than the 166. Same length as the others.

I had 3 XP sumit 800's last year. The only time they ate belts (166 or 377) was if the deflection was off.

dieselwerx.com · Nov 25, 2008

mine is the same way i found it best to run the belt a little tight and never had a problem soon as i loosen it up i would have problems.

Brutis20 · Nov 25, 2008

In my humble opinion...cleaning clutches, setting deflection, venting, old belts, gearing, are all poor excuses for the belt problems, they do help but is not the root cause. Its like having a plugged radiator in a car and cranking the heaters full blast to cool the engine - not the source but it helps (trust me I have done this...)

Plain and simple like you dealer said they are out of alignment and obviously gets worse as the motor torques up. Slot the engine mounts or shim the secondary and stiffen up that motor so it don't flex as much or buy a floating secondary system. Yes it is pathetic they come out of th box this way but that is whats generating heat. Same old story last year - what I think is funny is that most people were getting more than 100 miles on 377 belts on the '08's though - maybe BRP is moving backwards??

I would have your dealership drill out mounts, align properly and put in stiff MM or something to keep it from moving instead of bringing it in every week for "updated belts"...thats funny...

Anyway my rant is over!!

PS: What do you do with 365 blown belts from an XP? Melt them down, make a tire and call it a Good Year...

Team makes Polaris clutches and no problems with them other than some sleds have excessive belt to sheave clearance. Nothing like the issues people have with their TRA's. BRP gives the manufacturer(Team) specs and tolerances and Team makes them according to their specs don't they? I think the blame needs to be placed elsewhere(Doo) but maybe I'm wrong.

another ride another belt

Ok fellas, got my sled back last night 2 minutes before closing. They said the clutches were out of alignment but it does not specifically say that on the work order they gave me. What the work order does say is as follows:

"The units drive clutch ramps have been changed from 441 to 413, The unit was then test run and was found to be operating correctly through all RPM ranges. Both blown 377 belts have been replaced. Unit has 141.9 Miles."

"The PTO side front motor mount has been found to have been backing out. The motor mount bolt has been replaced, Unit has 141.9 miles."

"The unit was found to have BR10ECS plugs installed. The plugs have been replaced with BR9ECS."

I read the work order after they rushed me out of the store to load up my sled. I know there is a long post about how ramps work but what does dropping from 441 to 413 do for me? I'm assuming it is for the elavation that we are riding here in Alaska, sea level to 4000', but I could be way wrong. They would have had to realign the clutches if a motor mount bolt was backing out right? Why would this sled come with BR10ECS's? Anyways Rode it today and after the 7 mile trail run pulled over to check the belt. Everything looked good besides the cluthes were smoking hot. Babied the sled again, stopping alot and letting the cluthes cool down. At 28.3 miles noticed cords coming loose again. Ran it the rest of the day and the belt is wasted, 40 miles. Rode in 2 and a half foot of fresh and rarely opened it up over half throttle. I know I could have broke the belt in a little more but come on 28.3 miles. BTW my clutches were so hot that it is begining to melt my side panel. I'll take pics tomorrow and show you guys. Sorry for the long post but I just wanted to give you guys the heads up and ask for much needed advice. We'll get her fixed one way or another, just wish I would have kept my rev for a backup. Any suggestions would be grealty appreciated.

Sounds like you need some venting

Double L · Nov 27, 2008

Thanks for the reply RGM, but I think there may be more going on here than the need for aftermarket venting. I agree that it would help. My thoughts are that if everyone that had this sled without aftermarket venting was seeing their clutch side panel start to melt down after 190 miles and after three belts there would be uprising. Maybey when more people get some miles on their 09's this will bee the case but I'm hoping that mine is the lemon for everyone else involved. I'm just trying to get some ideas on what may be going on before I give it back to to the shop on Friday.

Blu Du · Nov 27, 2008

this is bad news. i should a bought a d8 or m8. i won't know if mines a pos until i get out west and i don't want it to sit in the shop

Adrenalin · Nov 27, 2008

my clutchs wearnt out of alignment ( well my workorder didnt reflect they were)

venting isn't a fix for BRP's inability to come even remotely close when clutching a sled.

Same crap as '08 concerning the clutches, why am I not surprised.

winter brew · Nov 27, 2008

The fix for the '09's is as simple as it was for the '08's.....proper alignment and clutch setup. Until you get rid of the reverse helix, ramps and gear a bit lower, it WILL eat belts.
We have proven our setup on the '08's and was going to wait until we get some time on the '09 before judging BRP's new setup, but with the amount of bad reports I have heard we will now offer our setup for the '09 as well.
Ramps, spring, helix, pin weights and uses a belt that costs less $$! :beer;

V-Man · Nov 27, 2008

What's the deal? Are they trying to push clutches to new limits? Is it the extra HP on new sleds?

I'm blown away to be reading about Doos clutch problems again, before the season has really even begun. Clutches are nothing new. They've been around for ever. You figure that's one part of the sled that would be rock solid. I think I've changed the belt on my wife's Summit 600 once in 8 years, and that's because a friend gunned it with the ebrake on.
