The fittings you see on the outside grease the rotec bearing, which holds the house onto the carbody. Grease these frequently but sparingly. To much grease at once can push the seal out that separates the rotec bearing and the ring gear, which is under your 3 bolt cover. The grease on the ring gear should be half the height of the gear. It is filled through the hole by whatever means you have. A 45,000 pound machine will take around 20 pounds of grease to fill if empty which is about 23 tubes.
