Super C Trans/Rearend Oil Check/Change

I want to check the rearend oil level and probably change out the oil. I see in my IT Manual that it holds 19 qts but I don't see where to check the level or where to drain and fill. Also what oil do I use-40 wt gear oil?
Thanks for any help.

Drain plug is at the very bottom of the transmission. Level plug is is a pipe plug at the right rear corner of the tranny, facing to the right side, about level with the center of the axle housing. Fill plug is a 1" pipe plug on the top deck, just forward of your shifter.

Be prepared to find hard sludge at the bottom of the tranny, perhaps so hard and thick that it won't drain. It might take a piece of stiff wire or a screwdriver to break it up so that it will drain. If that's the case, there's something to be said for draining only three gallons or so, then topping it off with kerosene or diesel and driving it a while, just to flush some of the sludge out of it, before redraining and filling with regular lube.

If you've got a belt pulley/PTO, you can drain another quart or so out of that. The plug is at bottom, directly under the belt pulley shaft. That areas gets it's oil from a slinger gear, but a lot of folks will start their refill with a couple of quarts through the fill/inspection plug directly on top of the pulley/PTO unit, then dump the rest into the main fill hole until it runs out the level hole.

Some folks run light oils like Hy-Tran in theirs, but that seems awfully light to me, and if you've got any noise in the tranny it's only going to get noisier. I run 90 in mine and it's just fine. (Original recommendation was, I think, 80.)

You get points for having the I&T, but I'll gently suggest you get hold of the operator's manual. The I&T is more a repair and adjustment manual, and is very good for those purposes. It's the operator's manual that has all the general maintenance info. The SuperC has a lot of little oddball things to grease (like the distributor) and the Operator's manual is the only place you'll find them all. Well worth having.

Thanks for the info. It was just what I needed. I have a 5 gal bucket of 140 wt. Do you see any problem in using it? The tractor is only used in parades in hot north Texas.

I use 80-140, I don't think that you would have any problems using 140wt.
