Once you remove the panel, there is a large, black Styrofoam insulator (bottom left in Grif's pic).

It takes an external Torx socket to get it out, but putting the new pieces in is relatively easy. Just make sure the lower rod is in place first, then slide the new tensioner body over it. Then torque the two external Torx bolts back down.
Here is a pic of the new and old parts:
I'm outside doing this upgrade now. Styrofoam did just slide off. No big deal. Aircleaner snout was full of dragon flies and grasshoppers once i twisted it loose from the rubber retainer on the back-side of the snout. Air filter was dark enough not to allow me to see any yellow while held up to the sun. It's the original made 2-06 not with 14K on it.
Back to the tensioner upgrade....
I will "assume"
the spring from the old assembly is not to be used
on the new assembly as it is not shown on Max BMW's online fiche?
Also, there is a notch made on the mounting flange of the new black cylinder near one of the bolt holes. Looking at the bottom of the assembly, there are also two holes that look to be for oil channels that may align up to one that is in the bike's engine.
From the larger photo on this page, the notch on the flange would be on the back facing the engine and isn't shown facing outwards (??). On MAX's BMW fiche it faces outside with the stick-on BMW label showing to the outside as well. If true, the large one in the jpg shown is mounted backwards. Wondering if it matters?
...but then again, they do not show the O-ring in the Max BMW fiche either although the new kit comes with one (opps. Never mind. It is shown as item #10, just no pic of it in the blocked image on the fiche.
(oh, a 1/4" socket fit the two Torx-headed bolts mounting the unit. Didn't have T40-45-50 (or whatever it is) external Torx driver socket lying around and I was afraid to call the Snap-On or Mac Tools man on a $aturday).
