Thank you for posting. I recently bought a 4020 diesel and appreciate any maintenance or restoration knowledge and experience.

Is this a gas 4020?

If you look at 5:20 you can see the injector pump next to the oil fill spot. Definitely a diesel.

How do you NOT have dirty fingernails? I can’t do an oil change without getting dirty. Nice move removing oil plug. Was sure you were going to get black hands.
