Drain Hydraulic Fluid From 1944 H

Hi. I just did what you are wanting to do. Who ever changed the hydraulic fluid on my H reinstalled the drain plug so tight that when I tried to remove it all it did was round off . first I tried a 12 inch crescent wrench and then 10 or 12 inch pipe wrench with a cheeter bar. and this was done on a work bench. Your drain plug will be on the bottom of the belly pump about 4" to the rear of the lowest point of the pump housing. It is the only plug pointing down. Just make sure you are on the belly pump. I had to drill out my old drain plug up to the largest drill bit that would just miss the threads and then I took a small pick and hook and chiseled with the pick to get the remains of the plug that was in the threads out . took a while but it cleaned up nicely with the pipe tap. I haven't put hydraulic fluid in mine yet. What weight hydraulic fluid will you use ? Richard

I found from another soars that the proper fluid is 30 weight non detergent motor oil, I found the plug and it came out not easy but came out, I was also told that 4-5 quarts would do but I think it will take a bit more because it just does show on the dipstick.
