the rubber on two of my idler wheels has came off i was wondering if the idler wheels are universal between yamaha, skidoo, polaris ECT.?

most sleds use the same bearings, however the diameter of the wheels vary from one sled to another if you are refering to a ski-doo the idlers are 5 3/8" in diameter for the skid wheels and 6 3/8
for the rears but check your rears, ski-doo used a larger rear wheel on their older sleds. hope this helps!

actually those numbers are a tad off. ski doo oem wheels are measured in mm. given you have an older sled chances are that your back wheels are 180mm and the smaller ones on the bottom are 135mm. the top return wheels should be 100mm. just call the dealer give them your sled and year & they can look it up. you can go with larger wheels but i wouldnt go too much bigger. if you want to get other design wheels(which are measured in inches) here is the formula to figure out the size.

inches * 25.4 = mm
mm / 25.4 = inches

eg
stock wheels for my 98 FZ 670 are 180mm & 135mm

180/25.4= 7.087
135/25.4= 5.314

so if you decide to go with another wheel id suggest a 7.125 for the back & 5.375 for the smaller ones.

also the bearings are a 6205 which is a 25mm ID bearing.

I know i just replaced all my wheels & bearings.
like i said though call the dealer & find out what size is on your sled.

they may be listed at a DOO dealer in mm but most catalogs i use
have converted mm to inches and the sizes that i refered to were from dennis kirk and two other catalogs i looked at used the same dimentions.

you are right most aftermarket wheels are listed in inches, but if you notice you cant get the exact size. the closest i could find to 180mm was 7.125 which is a tad larger than the 7.087(stock). also the closest i could get the the 135mm (5.314) was 5.375. asy you can see you will never find the exact size unless you get it from a Doo dealer, but you can get close enough to where it doesn't matter.
