Hello,

I have the following two items to replace the blade grips on my 300CFX, the items are BLH4504 (Main Grip Bearing Kit) BLH4502A (Aluminum Flybarless Main Rotor Grip Set). The parts in both of these items are more that the parts in the exploded diagram in the Blade 300CFX manual. So here is what I have figured out is the "stackup/layers" for all of the items in the Main grip.

Outer Bearing (in the grip facing the head)
Brass spacer (in the grip? did no find it in the bad grip)
Inter Bearing (in the grip facing the blade)
Thin washer (Did not find one when I took the org grips off)
Inner Race (Did not find one when I took the org grips off)
Bearing (Cupped side facing head)
Outer Race
Small Washer
Hex head bolt

So it appears the between the two items above I have more parts than what I need. So how do I put this back together the right way?

Regards, Dave

Hello,

Thanks for getting back to me, yes your post does help. I am assuming that items 4,5 and 6 are inside the grip.

Regards, Dave
