Tach Drive Seal Replacement - O-290-D

My bird has the O-290-D, which I believe has a little more complicated to replace tach drive seal. My seal leaked, the oil leaked into the cable and into the tach. I bought a new cable and seal and had the tach rebuilt/cleaned.

My question is if anyone has any suggestions for getting the old seal out. With a little google searching it appears like it's a rather tricky seal to remove. There's a specialized tool to remove it, but it's $314, seems hardly worth it for a (hopefully) one time job.

Any experience or insight? Thanks as always.
