The Motion Pro seal bullet can be reused numerous times. If you expect to do more than one fork seal installation, you can bet on the seal bullet getting its uses. Just make sure to use a bit of grease or oil for lubricant, and youâ€ll appreciate its utility. Remember: It only takes a single mistake using a homemade method to make you wish youâ€d picked up a seal bullet the first time. The seal goes right over the bullet and onto the fork, avoiding the bushing groove altogether. Otherwise, the groove can damage the seal, which can cause it to leak - obviously not the scenario you want when you've just bought a new fork seal and are going through the process of installing it. In this way, the seal bullet is like cheap insurance.
