I sure appreciate the responses other day (1-10-07) answering my questions, now I got more. I'm learning about dozers, but this dozer seems to be in pretty good shape. I bought it last year for my wifey....our anniverisary. Thought I was gonna have to sleep on it for a while too....she got a bit upset for some reason. haha Anyway,I bought it last year from a widow.... apparently the gentleman that had it really kept it up & spent some pretty big bucks on it in last few years he used it. I've put about 20-25 hrs on it since I got it.I been looking for manuals on Ebay & other sites. Anybody got any good suggestions where to look? My 12' dozer blade is hyd. up/down, manual angle. The tag on blade shows serial #16C5869, then 6A Bulldozer. In looking round for manuals I see 6A & 6S, then usually some serial #'s. Are these #'s for which dozer/tractor it fits, or serial #'s of blade the manuals fit? Also I see books & manuals like "44Hyd, 153 Hyd, etc," then serial #'s of book. Once again, these #'s fit tractor, or the Hyd system? I guess there will be a tag somewhere on the hyd system showing model #? And how I find out what hyd system my D6-9U ser#6914SP has? I haven't pulled any covers off yet, but need to. Fan belt is loose, but been keeping eye on temp. Need to service the tractor everywhere it needs. Another question: Does the hyd pump mount & run off the front crankshaft? If so, is there any U-joints in there usually that need greasing??? I learned the hard way on an old Ford 4500 BH I bought years ago....grease worms got it & spit u-joints out the front. Just about everything I've ever learned thru the years, I've learned the spendy hard way.....& usually it's been on some kind of machine that I bought to learn on myself. (semi's, dump trucks, BH, welders....now this dozer) Going to try to post some questions over on ACMOC forum when I can. Thanks James
