Steve,
Overall, the 50 hr service was very do-able. There really wasn't that much too it, if you've got a grease gun, a couple pans to catch oil, a funnel and some WD-40 or the like.
It took about two hours because oil filter and transmission filter were both tough to remove without the proper size filter wrench. Strap wrench wouldn't work because I didn't have enough room. I think I ended up puncturing both filters with a screwdriver in order to get them off.
The sediment bowl for the fuel filter was a little tough to remove also, because the FEL post was in the way; but the sediment bowl didn't take nearly as long to remove.
Also the transmission has a little metal pre-filter you have to remove and clean once the replacement filter comes off. That little pre-filter takes a couple wrenchs and a couple minutes of staining your neck before you get the retaining brakets removed.
Everything goes back together much easier, and you'll be glad when it's done; but, overall the project is very do-able.
Joe
