Yep.. sometimes it's just easier to spread out newspaper1
Speaking of oily concrete..I remember when i was repairing the hyds on my ford 8n... and an ordeal I went thru..
OK.. for starters.. an 8n is an open sump machine.. hyds, diffy, and tranny share a 5 gallon sump.
The hydro pump is a 'belly' pump, and is mounted in the lowest portion of the sump, under the hyds section, just ahead of the diffy. the pump base plate is actually the bottom of the sump.
I carefully drained the 5g's of oil out.. even let it drip during lunch.. etc. Removed the bolts around the perimeter of the base, dropped it, and another half gallon of oily sludge let loose. Seems the drain bung is ever so slightly higher than the bottom of the sump.. plus it is 90wt oil, nd there is usually 50 ys of sludge ont he bottom.. so it don't drain... well.. it does once the pump drops.. I had an oily mess on the garage floor that spread out almost 3' wide.
I put about 3 newspapers down and just kept working. took 2 days for the project.. on the 2nd day, after the wife left for work, I finished.. made sure the tractor worked.. backed her out of the garage.. tossed the papers into the trash, and then went to hand scrubbing the concrete with every detergent I could find. I actually got it 98% clean.... by the time the wife got home..
