Joe, Only the three rotor 20B  has a bearing between rotors, the two rotor 13B  does not - only bearings are at each end of the eccentric shaft (one in the iron front side plate and the other in the iron rear side plate - none in the center plate)  and, of course, the rotor bearings themselves that ride on the journals.

Not sure why the rotor housings were replaced – it may just have been easier.  I’m trying to remember the second area of wear. If I recall it was in the center housing where the E-shaft goes through the center housing and just on the forward 1/10”. Doesn’t the E-shaft rest on some bearing in the center housing?

 

I got the engine back in the plane on Saturday and turned it over with out plugs to check out oil flow. Oil flows quite well out the oil return line from the oil cooler by just turning the engine over. I then connected that line to the engine and removed the oil return line from the PSRU and turned it over. It took a while but began to get a good oil flow from the PSRU (of course I had emptied the PSRU of all oil when I took everything apart. So, now all I need is my EM-2 back from Tracy (hint hint) so I can start the engine. I’m a little skittish starting the engine without knowing what the oil pressure is J

 

Thanx Guys!
