Do I need a special tool? I'm afraid to use a screwdriver and pry it off...help.

 

Are you talking about the one for an underdrive pulley? I changed my pulley and used a flat tip to take the seal out. Just be careful, it's not difficult to do. Just email me or leave a reply if you have any other questions.

 

I did it! I replaced the seal carefully using the screwdriver and a plastic tire iron for my mountain bike. Thanks!!!

 

Good deal man! Glad I could help an ORG member out
