Well Darkseid, after dealing with lowsy HPI pulley fences I have learned that before assembling the drivetrain you need to "test" the strenght of the fences first. I to origioanlly placed the fences on backwards, but when I looked at the pulley it looked wrong, so I began to take it apart and when it came apart quite easily I knew it was wrong. Why the manual has the discrepency I don't know, I can only assume that the diagram was to make sure people didn't try to use the wrong part, and they also assumed that most builders would take one look at the fence and see the rounded edge should go in. Actually if the pulley was molded with the fence on the opposite side they wouldn't even need a fence on the resultingly (is that a word????) empty side.
Not to beat a dead horse, but I haven't an idea where you're coming from. Intuitively if you look at the fence it "looks" like the ridges are there on the inside of the fence and meant to go in facing the pulley. It doesn't look wrong when you assemble this way - it looks right because the smooth edge is on the outside. It looks like the other lip of the pulley without the fence looks.
I don't see what the point of having those ridges on the outside of the fence are for if they are not going to interface with the pulley.
Also - I tried putting the fence on "backwards", the right way, with the smooth edge in, and Darkseid is right, it's very easy to crack the fence. I used vice grips but when the fence nearly cracked I backed off and just put it back on the other way. If I have a problem and it comes off I'll CA it. If I hadn't read this thread there would have been no reason for me to think the fence goes on with the ridges facing out.
Much ado about nothing really - first time it comes off it gets a permanent bond.
