I was riding my scrambler yesterday down the road. I was probably doing about 50 miles / hour. I heard something make a pop like noise and I thought I blew a tire. I pulled over and the tire was okay. I tried to put it back into drive and go but it was making a "clicking" and "grinding" sort of noise. I then realized I still had the thing in 4 wheel drive. I know I shouldn't be driving at those speeds or on pavement period in 4 wheel drive so I think the problem was caused by me doing so. The ATV is automatic & chain driven (I think all the scramblers are). Any help would be greatly appreciated.

 

have u checked ur transmition at all it could have striped the gears in the trasn...or set the chain off....just mi to cents

 

Chances are you broke the main chain inside the tranny.

 

Check to make sure your front sprocket is still on the shaft. I wernt through the same thing on my TB and the front sprocket had slid of the shaft. I didn't have a pop noise tho. Just check the little thingsa before you go taking apart the tranny, but it does sound like the tranny chain to me.

 

I wanted to add some additional details that may or may not be helpful in determining the problem.

When in neutral or reverse the respective indicators display properly. When I put it in Drive the "D" indicator does not come on. Everything is blank, no indicator lights are on.

My main Drive Chain is not broken but exceptional loose. I put two people on it but it didn't tighten up at all. It's possible it was that loose before the incident, I'm not sure but I don't think it was.

I also want to be more descriptive with the noise. It?s funny but the more I think about it, I don?t think there was a ?pop? noise. I was doing 50 when I heard what sounded like I was driving on a flat left front tire.

Thanks for the help.

 

It ended up being the Main Tranmission Belt. Under the black panel on the left side (by your left foot). It cost me $47 to replace it.
