288 and 377 are wider than the 166. the 377 is 4mm shorter than the 288 and 166.
The new 377 Belt?
- Thread starter northof40
- Start date
So to repeat an earlier question - has anyone tried the 377s on a pre-08 800? It seems like they should work with just a deflection adjustment...
And why has Skidoo suddenly admitted to a problem with the 08 sleds that has been ongoing (at least for me) for years? I.e. Excessive heat has been causing premature belt failure on my sleds for as long as I have run a 700+cc twin mountain sled in deep snow. What has caused Skidoo to do something about it? Any ideas?

I picked up 377 last week for my 06' summit adreniline ($140 ouch) and have about 200 miles on it riding the deep stuff. So far, so good, belt still looks brand new. Had to go up a number on the clutch adjustment to get full rpm's though.
Can you run the 377 on an 05??
got an 05 summit, what do you have to do to run it on an 05??

do these new belts work on the 07's ?
yes they do!!!
Have close to 200-miles on my first 377, still looks new other than the belt dust. However, during the first ride with the 377 I felt it slip once as I was crossing an open flat area with about 10-inches of fresh. Was doing a steady 3/4 throttle around 7000-rpm and heard / felt it slip just for a moment. Then during my last ride (Spring time conditions with temp around 35 deg F) my belt was slipping and motor was over-reving (hitting rev-limiter) most of the later part of the ride, and mostly during steep climbs.
Anyone else experiencing these problems???
My sled is an X-154, and I ride from 8200 to 10500-feet. Clickers set to 3.

I think you have those turned around.... 4mm wider is A LOT!!!
I put the new 377 belt on my sled and withing 120 miles it blew into a hundred pieces. I checked it at the bottom of a very steep pull, clutches were cool (we had been hanging out for awhile putting the 4 missing y-pipe bolts back in my buddys XP) and no cords showing. Started ripping up a steep climb, got about 300 yards up and the belt exploded. Sled started going backwards down the hill, I jumped off, sled slid into my trench turned on it's side and stopped somehow.
This exploding belt thing really stinks. Now I have a fear that this will happen again at a very bad time. BRP Fix It Already!

I threw a 377 on my '07 and found I had to drop the belt so low in the secondary to be able to start the sled (or not creep BADLY at an idle) that it was about 1/16" BELOW the top of the secondary sheaves and was still too wide to have correct belt/sheave clearance on the primary. I took it off and returned it....not sure how others are making it fit without shortening the C-C. ???
I wanted to run one just for grins but have had no problems with the 166, plus it's less $$.

This only happened to me with the 166, I thought for a moment that the drive shaft broke. I finally decided that a bunch of snow got in on the clutch.
Try the Gates Extreme, it was cheap from Napa and better than the 166 but now I will use them up on my kids zx. 38x4320 is size and model
$74 CAD and I hear $50 US.
Blew a 377 yesterday. About 1200Km on it
