 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.

 Talked with Maurice and his wishes would be to see it flying.........it
 needs to be rebuilt and upgraded and I said I would get the engine to
 the point it could be installed..

 It will be sent back to Racing Beat inspected, rebuilt, run on the dyno
 as before...I told him I would fund that...

 However my pockets are not deep enough to get the airframe and would be
 looking for a partner to acquire the right experimental for the
 project(preferably RV8).

 I agree with you Paul on the re-drive, but it needs some work to get it
 right and would stick with it or something like it in whatever form.

 To set the record straight, I do not own the engine..I am just trying to
 see his dream come true and there will be spin-off positives back to me
 in other ways...

 He declared I would get whatever contribution I made back if it
 ultimately sells or grows into something more...

 To keep the cost down you could leave the box as a 2.17:1
 and just add the thrust bearings for the sun gear.

Would that thrust bearing also fit the 3.17 Ross drive?

Lewis Bjork

Yes.
