Oil?

If someone installed petcocks on the right side of your oil pan they did so to replace the standard pipe thread plugs that came on the tractor. You should open the top one and add oil through the cap in front of the mag until oil begins to come out. Close the petcock and stop adding.

These old engines will use some oil, but if you keep the level up it will run forever. I drain and refill my engine oil once a year (only put about 50 hours on it each summer to mow), but check it regularly and add as needed.

There will be engine oil in the cluch housing as the earlier Cases have wet clutches. When changing your oil you need to be sure and drain the clutch housing as well. It will fill itself back up from the crankcase when running; so you need to top it off after you run it for a bit.

My SOHIO chart for SC says 5 qt capacity. Says to use 5W for below 10 degrees, 10W for 10-32 degrees, 20W for 32-90 degrees, 30 for above 90.
Transmission capacity is 83 quarts of 90. Check level at filler plug on back of tractor.
