How much engine oil is in an International Harvester UD525 power unit?
I need to change the oil and filters, I have never worked on one before. It was made around 1956, it's a large diesel power unit that starts on gas.
Guess I should state I've been an auto tech for 30 years, tried all the easy stuff. Nobody knows about this dinosaur, hoping to find someone out there with experience from the old days. Got the service and parts manuals, no help. This engine was installed in crawlers as well. I can drain and measure, probably will, but you know...
