Jim the formula I always used for tank capacity is length X width X height / divide by 240 should get you close in gallons..with basic 15w40 going for $16.50 a gallon,it would be a couple hundred to change that oil. I'd keep workin on it with your 'dewatering' process..great job
I'm bass ackwards. your number would be more accurate accounting for baffles, plumbing etc. I have my days.
either way I'm looking at a 40-gallon tank. 8.5 X 32 X 36. I sure don't see a need for that. this truck did at one time Have hydraulic connections at the bucket. I assume it was for hooking up implements like saws & stuff. for what the system has now I'm sure that I could make do with a much smaller tank. shit that sight glass will NEVER see a level. I see no need to have that much oil. Don't run the truck long enough to get the oil very hot.
