Do an internet search for a Ford 8010 Service Manual. You should find ssbtractor.com has a service manual for $54. I'm sure there's others with service manuals.
Incidentally, there are many Operator's Manuals for a Ford 8010 on ebay. Unfortunately, I did not see a Service Manual. I prefer the I&T Shop Service Manual - it's about 100 pages and very useful. You might keep an eye on ebay - they'll probably have one for sale one of these days.
I called ssb tractor this morning, and they do not have a service manual for either a Ford 8010 or a New Holland 8010. That quote I gave you yesterday was for an Operator's Manual, not a Service Manual - my mistake.
They were going to check with another warehouse to determine if they could get one for you.
