Picked up the engine today..dusted it off and it still looks good. It's
been about 15 years since being turned over, still has compression...

there is some damage on one intake runner that  got banged in and the
fuel injector lines in various places are dinged....


Ross reduction unit has 4 planets and a bunch of end play......Was this
designed for CS prop??? the engine is setup for it.......


Not sure what to do with it but I think its time to disassemble,
inspect, rebuild for display only.....pull what ever info or ideas that
are worthwhile...

Sure is beautiful. It needs an airplane :)

Not a CS prop PSRU. Probably a 2.17:1. I think it can be converted
to a six pinion 2.85 to get the prop to rotate in the right direction
and allow the engine to rev up and gain a little HP. It probably
also needs a thrust bearing added for the sun gear.

Jeff,

Curious as to how you ended up with this engine in the first place? I knew
the original owner for a lot of years and first approached him about putting
the engine on my RV-4 about 10 years ago. At the time he was looking to
market the engine and I thought it might help to get it on an airframe and
get some visibility. He declined. Last time I saw him about a year ago he
asked me if I was still interested but by then my engine was installed and
running so I said no. I think he regretted turning me down. I recently heard
he'd died and I wondered what happened to it. You've got a real nice piece
of work there. Hope its going on an airplane and finally going to fly soon.
I would recommend dumping the Ross drive though - Maurice had problems with
it and was going to switch to an RWS drive.

I like it because it is better designed and therefor 10 pounds lighter than Tracy's.
Two inch hollow prop shaft (stiffer, stronger) and better housing casting.
