I got a slightly rough and modified Olympic .15 last Sat. in Lexington, NC real cheapo. Turns out that I have enough other new and nearly new parts on hand to piece together a fairly decent looking specimen. However, I'm going to need to switch out the prop thrust plate (among a couple of other things) to get there. The Olympic has ball bearings and I can't find an exploded diagram of this engine and I don't want to botch this piece up while removing the thrust plate. Help please.

I replied to this earlier must have forgot to hit “send”

Anyway, if anyone will know it will be Jason, hopefully he sees this. The one I have is brand new and I have not disassembled it. I would imagine the crank is not pressed into the bearing, so it will probably come apart just like any .15.

I would wait until Jason posts before doing anything.

I used an arbor press to press it out. Threaded in a hardned cap screw to press against. The standard prop screw is too soft. Came apart just like any other .15. The rear bearing stayed in the case. Must keep it straight when pressing it back together. Cutting new splines in the new drive hub takes some force for the .15. I use a spacer with a hole in it to press back together as the drive hub has the prop hub sticking out.

It’s been a while since I did one. Peterparisparts on eBay is where I got a new drive hub from. Hard to find part.
