i am about to install the works throttle body shaft seals and in the instructions they say to use a seal insertion tool. i dont mind having to buy one for a proper installation. can anyone tell me the exact size i need to buy, or a specific tool for the job? thanks

 

The key is something round with a flat end. Our maching shop fabricated it's own tool for just such a job, but we've had guys using small sockets do the job effectively. You just want to make sure the seals don't "walk" as they're being pressed/tapped into place.

 

i used a small socket and a rubber mallet to "tap" them into place. worked perfectly.
