I regret that I caused some confusion.  I am currently not having an oil pr=
oblem that I know of.  I just wanted to become more educated on how the oil=
 flowed into the unit since I observed in entered slowly.

Of course, I may have other issues yet undiscovered.

All the best,

Chris,
  Not Tracy but prop shaft main bearing is a sealed bearing not lubed by en=
gine oil.........The
other bearing of the prop shaft is a sleeve (plain) type and is lubed at en=
gine oil pressure....
 The planetary gears also are lubed from engine oil pressure..............

-------------- Original message from Chris Barber <cbarber@texasattorney.ne=
t>: --------------

I just received my PSRU back from Tracy.  If I understand his explanation c=
orrectly my prop shaft bearing at the end near the prop (pusher) bound up s=
omehow.  He machined it, made other needed adjustments (?) and sent it back=
 to me very promptly...bout a week turn around (of course I dropped a bit o=
n overnight shipping to make sure he got it before he was off again <g>).

The problem may have been due to a couple of factors....not really sure, bu=
t I discovered it after my plane was sitting out of the hangar due to roof =
repairs for about 6 or 7 weeks.  When I went up to start it to taxi back to=
 the hangar, I pulled the prop through a few times by hand and all seemed f=
ine.  I started it up, started, was tickled, but it it stalled. Did I menti=
on it was REALLY cold for Houston...about 27 degrees.  I started it again a=
nd is sounded "labored" and was running poorly.  It was about 1:00 am (I ha=
d just gotten off duty), so I figured I call it a night.  I got out and tur=
ned the prop through again and could barely turn the prop. Damn.  I thought=
 I toasted another engine. Damn.

A couple of days later a friend and I pushed the plane back to the hangar a=
nd I walked away from the issue for a couple of weeks. Went so far as to ev=
en looking at financing a Lyc <shudder>.  I distracted myself by doing some=
 interior work and wiring...actually got my radios far enough along to list=
en to ATIS for a few minutes...on the bench.

Finally, two days after my recent loss, I forced myself to the hangar and p=
ulled the PSRU.  I had already looked inside the exhaust ports and the cham=
bers looked clean and smooth.  I had also drained the oil, with a magnet (I=
 know, some is aluminum) in the drain filter and found it all to be perfect=
ly clean.  Well, without the PSRU the engine turned perfectly making that s=
weet churning sound through the open spark plug holes.

I turned to the PSRU.  I took out each section slooooowly.  No signs of bin=
ding, chipping or any other damage in each part....until I got to the last =
section, the sealed section by the prop.  The prop hub would not turn.  I c=
ould barely turn it with the prop on. Without the prop is was a no go.  So,=
 I sent it to Tracy.

ANYWAY, now that I have it back mounted on the bird I am curious as to the =
oil going into the system.  Even though I went through this long explanatio=
n, I only have a questions about the oil entering the PSRU.  There is no re=
ason to suspect any oiling issues caused the previous problem...I just like=
 to share on occasion.  However, last night when I was hooking up everythin=
g I decided to pour some oil directly into the in oil hole on top of the PS=
RU.  My curiosity is that it just kinda set there and very slowly seemed to=
 seep into the PSRU.  Does oil pressure forced it into the PSRU, thus getti=
ng more oil in.  I would think with everything spinning etc under power the=
 oil flow etc would be much more dynamic, thus providing a more significant=
 lubricating event.  I don't really know what I was expecting.  my oil flow=
 seems good.  It just got me thinking and wanting to have a better understa=
nding.  TIA

All the best,

Chris
