Balancing
#1
This question has been asked before but I've never seen the answer. Anyone care to share the weight of the oil figured for a 13B rotor? Only thought is that it would be the bob weight given by Mazda in their outline of the balancing procedure minus the given rotor weight and the weight of all springs and seals. Thanks!

I don't really know either.
But the centre iron has a hole for the crank to spin in the middle of, that hole is cast to drop anything into the oil pan. The rotors when assembled, the cooling side with the vanes go on the centre iron. The jets being on the crank spin 3 times faster than the rotors (stationary gear ratio), and spray at the vanes of the rotor.
I believe oil is splashing into the rotor and eventually being flung back into the centre iron and dripping down back to the oil pan.
I don't think they are actually full completely at any point.
Say the centrifugal force was holding the oil in the rotors. As you spray oil into the rotor, and spray and spray and spray, the oil "level" can only ever be as high as where the holes are cut in the centre iron for the oil to return to the oil pan.
You'd have to get out your fancy drawing board to illustrate it. Here's my MSPAINT attempt. This is a REALLY quick sketch and not even entirely accurate (at no point does the combustion chamber ever see the oil crank hole ). But this is to STIMULATE your MINDS! Consult your pile of scrap 13B parts for actual measurements and more information.
