Removed the old seal and cleaned the seal housing cavity - seems to be pressed into place. Was any lubricant used or needed to press fit the new seal into place? Adhesive/loctite?
It's pressed in. It can easily be forced into place by using a wrench socket of equivalent diameter as the seal... and a hammer.
Place the socket so it lines up with and rests upon the outer periphery of the seal. The seal should be sitting squarely (not crooked) on the hole's lip. Keeping all that as straight as possible, gently tap on socket. Only do a tap or two at a time, then stop and check the seal to make sure it's not going in crooked. If just the tiniest bit crooked, try adjusting the angle of force. If it's going in too crooked, you might damage the seal.
Do this...a few taps at a time - until the seal is fully seated.
You may want to make sure that the lead edge of the housing has no sharp edges or burrs and is clean. The outside of the seal has a elastic surface to seal is, so just a light coat of food safe lubricant on it will make it easier. Something like sanilube.
