cat E70B Excavator greasing

[Tracy Brown]

There is a metal tube sticking up in the floorboard near my right heel that has a rubber cap on it. You pull the cap off and there is a grease zerk there. What does that grease? The hose is missing off the bottom end and I need to know what I'm Not greasing. I assume it is for the big spur gear that spins the cabin or the swing bearing.

My guess would be the house (cab) bearing.
Usually grease it while holding the swing lever to rotatete 360

In the link is the is the online Cat part site. Their deal is that entering the serial number of your machine makes the use of the site much easier or so I would hope. I did have the E70B selected when I copied the link but I have no idea if it will transfer in the link.

Other poster is correct. It is for greasing the turn table. Our 307 is same way. Newer ones are outside on the turn table below the boom.
