Float/maintenance charging is fine, but I do like a proper full charge put on the battery first. Before a maintanance float, check the water, then bulk charge at high amp charge rate. Then switch to low charge to get through most of the acceptance "top off" phase. Do this with a good MANUAL...
Not to derail things, but wasn't the 5.9L Cummins first developed by Case? I'm rather ignorant of the farm tractor world, so I don't know the connection between Case and IH. BTW, I enjoy your posts regarding the MAN/Continental multifuel. Very interesting reading.
If ya want to keep it simple, 15w40 HD oil for the engine (whatever is cheap, or the coolest lookin bottle), and the afore mentioned NAPA GL-1 for trans, transfer, and all 3 diffs. I don't know about your budget, but as far as I'm concerned the capacities of these trucks are too much for $$...
For GL1 (pure mineral oil / no EP additives): NAPA 65-205 for 5 gallon pail, and I think there is another, NAPA 65-201 for 1 gallon jug.
Good enough for me, though I wonder who else uses this stuff besides MV owners, and farmers with old tractors. I know, who cares?
All this is true. I'm still going to do this though. Its too cool not to. Not to mention, when the storm of the century hits up here, he that owns the biggest plow is king. Kinda like in the south after a huge hurricane hits, he that owns the biggest generator is king.
I get the sense that the 915, 916, 920.. are better road trucks i.e. more power, auto, and more civilized. M818 is more old school and seems more fit for heavy off road use. I don't own a 900, just have experience with the M818. My 2cents.
