You're right, Ironbark--I have little experience stripping/rebuilding engines. The extent of my knowledge is rebuilding chainsaw, but parts were available and videos were a'plenty. Also, I have several saws so the risk was less if I failed. I only have this one splitter that is currently out of commission. Splitting season is around the corner so aim to have it ready.
I'm really trying to keep up/follow everyone's considerations/suggestions. They've been good... Very helpfuI, and food for much thought.
I still don't understand how I could modify the 3" shaft (attached '0068') to spec of 2" shaft ('0066'). The length isn't what concerns me--a cutoff wheel handles length easily. But the keying of the shafts is entirely different. If was to cut the 3" shaft to 2" in my first step, what is my next step? To me, it would seem I'd need to "turn" (in a lathe) the shaft to maintain uniform diameter? I can't imagine trying to do this with the shaft "static" while I'm operating dremel. I really feel like I'm missing something here. And then, if somehow successful at removing the material to the spec displayed in '0064', I'd still need to figure out the protruding key.
Doesn't sound like an option, but from my layman mind, I'd like to purchase a pump coupler that mates with the '0068' shaft. Would likely have to reduce the length of the shaft, but this is fine (this part I'm comfortable with). But moot as I guess such a coupler doesn't exist.
If nothing else, I just hold to the new motor for rainy day... Work on the old motor that seized up due to low oil running on very un-level surface. I've read these have forgiving tolerances that bode well at a chance that once unseized it still has compression... But time will tell as I work on it. And working on something that is broken is always justified. My hope was to have two identical motors, but the shaft is a critical component and it greatly differs between them. It happens...
Aside... Unseizing piston... I removed the plug months ago and flooded the cylinder with penetrant. Attempting to pull start still is unsuccessful (I expect this) at getting it unseized. Is next step attempting to torque the shaft, or better to access the piston in attempt to break it loose (thinking piece of dow and mallet). If torguing shaft, I've been thinking of what kind of "lawnmower blade" type part I have that I could attach to the shaft to gain leverage. The plan isn't really to crank the hell out of it, but to jar it back/forth some in hopes that something gives. Ideas on this?
Thanks to everyone. Big help. I'm learning a little too.
