Water pump seal install problem, please help!

So I got my new to me 2011 RZR home the other day. All excited after a couple trouble free rides, I notice some antifreeze coming from the weep hole on the water pump. To my relief, the dealer actually had a seal in stock. So following the great instructions on this site, I removed old seal and began to tap the new seal in, when the black plastic centre piece broke into 5 pieces. I’m trying to figure out what I did wrong. I did not have a 32 mm socket to tap it in, so I used a 1.5 in piece of PVC pipe. I used a dremil to bore the PVC a little, but seamed to fit perfectly around the brass edge. I almost had that sucker all the way on when it broke. What exactly do you use to install the new seal? Also there is not much room to get a hammer in there, any suggestions? What is with the clear plastic cover that comes on the new seal? I cut it off before installation. Was I supposed to leave it on and remove it after I tap it in? Anyways, I have to wait a week for another seal. All help is greatly appreciated. Thank you.
