Joe, I have the service manual and it is NOT much better than the owners manual. Just more detail on the insides of the equipment, no better drawings of plugs and such.
I just did the 50 hour service this weekend. I did the engine oil and filter - piece of cake. I also drained out the hydro fluid, messy, but OK to do. Checked the suction screen - took longer to FIND the thing than it did to check it. NO filing at all. Filled the sucker back up - pretty easy with 2 big funnels and a drill powered oil sucker/pusher that I use on my boat oil changes. (Yes, I rinsed it until it was clean before using it! Can't be too careful)
BUT, I didn't do the front axle fluid. On an
L3410 HST what's in there? 80W-90 or hydro fluid? i didn't have enough of either to do the job, so I'm stalling until next weekend. But, I would rather have the stuff (what ever it is I need) on hand before cracking the seal! Any one changed the fluid ???
While it's still in my short term RAM, Here is what I learned on the 50 hour service.
1) The yellow hydro filter is on da_n tight! It has No "ribs" on it so the filter wrench slips. I had to use 80 grit sandpaper folded over between the wrench and the filter to get a grip.
2) All the filters dribble oil on you, and everything else. I used a big funnel to catch the fluid and direct it into the 5 gallon plastic jugs.
3) If you drain the high points first and completely, you don't get as much of a bath when you drain the low point by the mid-PTO.
4) I drove the tractor up onto some 4x4 posts to gain extra ground clearance. BUT, I NEVER trust that the tractor (or car) won't fall on and crush the living S__t out of me. I know someone that died that way. Not crushed to death, but just compressed enough to not allow any inhaling. Not nice. Your last 4-5 minutes are spent thinking, "Why didn't I block this thing up??". Always respect gravity, it don't care about you, at all.
5) The screen is a bear to get out. I undid a spring that goes to the hydro pedal to gain extra clearance, but it was still hitting on linkages and "stuff".
6) After spending a couple of hours under the tractor, I have to say that it's is a real nice piece of engineering. Everything is tucked up out of the way real nice. I would like to make a belly pan to go from the bottom of the FEL mount to the draw bar using the FEL frame as a mounting point. Anybody done that?
