looks like a tight fit,any tips to make it easy

I just did mine .... I put the seal into the bottom of the channel, and then used a blunt flat blade screwdriver and pushed the top into the channel. Went right in with no problems. I did push the seal to "compress " it rather than "stretch" it so that amybe it wont shrink so quickly !! Maybe I did it right ..........

Yes, drop the drive train ...

Do it like David said.

Don't try to start at one end and slide it on, that does not work too well.
