BLOWN BELT / COOLANT EXPLOSION

[kyleshane]

Was riding across lake yesterday and my 2003 RX1 with 2800 kms blew a belt and in doing so the coolant exloded out the bottom of the sled. It is now stuck up north waiting to get picked up. My question is ...has anyone ever blown a belt on their RX1 and if so has it ruptured a coolant line. Im hoping that is all that happened but not sure until it gets to a shop. The belt blew into a million pieces and is shredded into the clutch. Not a pleasant experience and not an expected one for a fully serviced sled with only 2800 kms. Yes we do lots of full throttle riding so I am being told to change the belt every season.

belts

i have blown belts only when my alinement was out. there is a metal cover over the hose on that side. is it in place?

 

[kyleshane]

there is a hose that runs through the plate, about 1 inch thick that is exposed for about 4 inches

I blew a belt last year that exploded really good when I was racing and it went everywhere!! I suggest that you take the side cover off and get to your clutch and secondary and clean it all up andd out. Use acetone to get out all the nasty rubber grime.

thats nothing....mine literally disintegrated into hundreds of 1 inch pieces...
and even though i dont see a hole in the hose that comes through the motor im hoping that is what it is..will find out tonight.....my coolent flowed out the bottom in literally 5 secs

I know it doesn't look like much but the entire top of the belt was gone into a million pieces. I was lucky I had no real damage except one hell of a mess. I'll bet you flat out cut the hose.

Or yanked the hose right off the steel pipe it connects to or the heat exchanger.

I was looking at that hose yesterday when I was changing my belt.

I was wondering what would happen if a belt blew.

Now I know!

I will have to keep a close eye!

ok I have the full scoop.....
when the belt disintegrated it bent the cover plate back and one of the pieces hit the hose so hard it dislodged it, causing the hose to fall off and split. My Yamaha mechanics have never seen anything like it. They believe that these belts should be replaced every 2000 kms. The torque of the big motor and weight of the sled and the combo of high speed drags and runs will create more of these problems.
learned my lesson.......check/change belt frequently....cheers all

Changed my belt at 4500 miles. Still looked good and debated leaving it on. Perhaps it was an omen that I changed it.

belt

Man thats bad....

what belt is best. IN my experice it seems on Yamaha sleds that the oem belts work best.

What belts do you use????

I am currently running the yamaha...
