As long as it isn't totally damaged, it should be okay. That won't cause a leak. It is there for just one reason, to keep dirt out of the seal/bearing.
If you want to, take a pic of the part so I can see how damaged it is. Hopefully, I will be able to tell if it will still do its job.
Take care,
Joe
