I have the parts in hand to do mine now too. I hope it works as well.
As a side note, what prop do you have? I have a 3-blade 68" warp with tapered nickel leading edges. 450 hours tt on the motor.

fantastic. when i left the airport last night I saw you going out the gate with your airplane in tow. I take it you went up to deer park with it. did you get a chance to fly it yet. I know a few years ago they complained of a rough engine and it kept the airplane from flying. glad you found the problem. what parts did they change out, very curious.
After diagnosing with techs at LEAF they thought (for me) it is a problem with the Bellevue washers. These are cupped shaped washers that make up the spring that retains the driven gear in the gearbox, similar to the two stroke boxes.
I was sent these washers, the retainer half rings and all the lock washers and gaskets to do the install.
I'll take some photos of the job when I get to it, and post them here.
back when I had the early 912ul, I replaced those bevel washers because they wore so bad. Not sure if it ran smoother after ward, don't remember. It was a few years ago. with a press, it was a fairly easy job.
There are a couple you tube videos out there that show the process, doesnt look that hard to do
Flew it this morning- spent about two hours in it running around the patch with no issues. Gonna spend a couple of days up in Deer Park til I get used to it then fly it back to my hanger at Felts. Felt great to get up in the air again- with all the issues I was beginning to question my purchase![]()
Here is a couple of photos of the rebuild process.
The bellvue washers are 5th from the right in the last photo.
The old ones are .2015 and .2030" thick. The new ones are .2145 and .2205" thick.
Quite a difference.
