Different tractor....same proceedure.
I just finished last week, installing new oil pan gaskets on my 150 Massey Ferguson. (Perkins 3 cyl. had a tendency to blow out the rear pan gasket and dump oil in the bellhousing. (New O.E.M. gasket is kevlar re-enforced rubber instead of cork now)
The entire operation took about 3-1/2 hours.
Wedge the front axle against the axle bolster (with wooded wedges) That keeps the front end "rigid" while unbolted from the engine. Block under the tranny. You want to take weight off the front end, WITHOUT lifting the wheels off the ground, while blocking under the middle.
Never had ahold of an 8N oil pan. The one on my Massey was about 50 to 70 lbs. Have a floor jack handy to lower the pan once it's unbolted.
It sounds like a major task, but all in all, not that serious. There-in lies the beauty of old iron. Anyone with basic hand tools, and some mechanical aptitude can repair about anything on one.
