Leaking output shaft seal

[Meanwhile]

Thanks JMBT, mine is definitely leaking. I’ve been checking it and adding oil the past couple days. Looking at that seal, it looks like a larger version of the ones on my pickup. Normally I’d attempt it but I don’t think my tired old air compressor could do the job. I can’t justify buying a new compressor and impact right now though I’d really like to. I’ll figure something out over the next couple days. Thank you all for your input and assistance here on this forum.
