On the underside remove just the outer perimeter screws: 13 screws plus the 6 screws along the underside of the front rail (top edge in photo)
Lift the hood and rest it back against a pillow on the sofa so you don't have to unplug the wires.
Remove the 7 millimeter nut from each end to finally remove the black metal front rail guard (black metal panel shown to the right of wrench).
Side view : Low A was removed. Metal weights on the fronts of the hammers. Front guide post is seen to left of green felt. Guide post is black plastic with white factory grease smeared on the side and top. Pink colored contact sensor is shown plugged into green chip board under the white hammer tops.
The end of a Magic Marker pen spreads open the pronged end of the key which releases the key (removal).
Another view of releasing the key, note the pink grease on the rear hinges
The grease has slipped down and off the front guide post of a black key
White grease has slipped down the black front guide post, it looks like a small blob of shaving cream.
Overhead view of front guide posts, you can see the blobs of white grease on them.
Using a round toothpick to liberally swirl new grease all around the front guide post for a black key. Note the key weights beneath up front on the right side.
Out of focus view of greased front guide posts.
I like to apply it thick and heavy so I don't have to do it again. The two big blobs are for black keys. The smaller blobs are Roland's original grease. For the black keys I cleaned off the original grease with q- tips and denatured alcohol.
Pointing at the pink grease at the back hinge where the key snaps on and off. No need to add grease there. Notice the pink contact sensors are peaking out from under the white plastic hammers in the middle. The contacts are plugged into the green chip board.
Pointing at the pink grease on top of the hammers. The key (removed) has a plunger that pushes into the pink greased causing the hammer to move down and strike the sensor underneath. No need to add grease. Notice pink contact sensors peaking out from under white hammers. Notice front guide posts with fallen white grease are on the right side of photo.

Close up of the grease wells in the middle tops of the hammers, the key has a plunger in the middle that presses the hammer down on the sensor contacts. No need to add grease there.
