hi the part of the front part of the chain where go like the front sprocket for the chain because i think the teeeth are worn out any buddy kno the name of the front peice ?
does anyone know how to take out stripped bolts???

 

kx, you'll likely need to replace both sprockets and the chain. Driveline wear is like DNA of inbreeding; if one gets it, they all do.
Which bolts do you need to remove? Make sure they're correctly identified as left-hand or right hand.
Be specific as to what you're doing. We'll be glad to offer advice.
Gear up; stay safe.

 

Yes please be more specific.
and how bad is that stripped bolt and where at? Good luck.

 

its the bolt to loosen up to move the tire back because i thought the chain needed to be tighten and i found out that is was the sprocket not the chain and i need to loosen up the bolt again where i pull the tire back sum

 

If that bolt and adjuster is stripped, then there is no way you can properly adjust and align the chain and sprockets. You will eat up chains and sprockets let alone run the almost sure chances of jumping a chain and taking out your case at the same time.
