ahhhhh!...
O.K.....so I know your cleaning them now!.....:rofl: Your looking how to take out that MAG side......:rofl: Yeah, it's a pain in the royal butt, but I found an easy way, as it seems you already figured it out.
Once you pop the cap, get a metric socket (I don't remember the size) and holding the bellows assembly in one hand, remove that plastic looking nut in the center. Then, the bellows assembly will come off. You don't have to worry about the guillotine valve. There is a stop on it and it will not fall into your cylinder.
After you take out the bellow, then you should have enough clearance to remove the two allen head bolts on either side and just slide it out.
Make sure, when you clean the RAVE, you look at the bellows for any cracks or holes. Make sure it's still soft and in good condition. Make sure the little hole you see in the engines casting is clear and the one in the RAVE is clear. Be careful while cleaning the holes. You dont want to drop anything in there. Make sure the guillotine slide valve slides in and out smoothly. When you put them back together, you may want to adjust the little red caps all the way down. If yours are flush with the black plastic housing of the rave, then your adjusment was made after the supplemental. I find mine works better where it was originally set and that was all the way down.
Let me know if you have any more trouble............oh, and don't force nothing. You sure as hell don't want to break it........you'll be up that ole mans creek without a paddle!...............:ack:
