My Feedback http://www.3wheelerworld.com/showthr...ck+shortline10
Ahh, I see. How would one go about getting the right side bearing off on a 200 model though? With the oil pressure pad on that side I wouldn't really want to push on it??
Is there anything wrong with lubing the shaft? Make sense to me, though you wouldn't want it to turn on the crank obviously.

By oil pressure pad do you mean 12/13 in the pic below?
I don't have one right in front of me, but if it were me, I'd tap or press out #17 and remove the pad and spring to see if it would be possible to press on the shaft then. If not I'd probably use a thick washer and a socket. Put the washer inside the socket, place it over the end of the shaft and then press it off. The thick washer, or multiple washers if neccesary, should protect the end of the crankshaft.
ETA: Nope, nuthin' wrong with lubin' the shaft, just ask glamy
You may not have picked up on it barnboy, but "lubing the shaft " was a tiny bit of double entendre.
ETA@: I just looked at a good pic of that end and I would be removing that pin, spring, and pad to do a thorough cleaning anyway.

How the phuk did we get here from rebuilding a crankshaft?
I was born and raised on Venus & I may be here a while.....
What the!!!!!!!!
Did I really just get this lucky? I’m having a hard time believing it.
I used a good engine assembly lube and pressed my crank together.
The rod to crank side clearance is .0025
I figure it will loosen up a little as it breaks in and the thrust washers wear a little.
So...I get it in my little indicating fixture, zero out my indicator and it doesn’t move.
Hold on. I’m doing something wrong. Get out my flashlight and look closer. My eyes suck.
My indicator is .001 reading and I can see an ever so slight movement. So I go dig out my Interapid test indicator and ditch this cheap travel indicator. It’s tenths reading and will REALLY tell the truth.
Setting it on the furthest out machined journal I get 6 tenths runout.
.0006!!! Uhhhh, I’m calling this good!
No adjustments. Straight out of the press.
I had to have done something wrong. Nothing ever works out the first time. So, get the air hose and check my oil passageway. Squirt some penetrating oil in and hit the air. Oil squirts out around the sides of the rod. So that’s good
F me! Did I get lucky or what!?!?!
.....wait, NO! I’m just that good right? .....yeah, I’m just that good. Lol!!!
I guess even a blind squirrel finds a nut ever once in a while.
I was born and raised on Venus & I may be here a while.....
....ohh yeah, it’s a brand new SPI rod, bearing, thrust washers & crank journal.
Set me back just shy of $40 on eBay.
I am curious about this crank journal I just installed though.
The factory one had no holes in the side. This one does and has some cup shaped inserts pressed in the holes on each side.
The cups have a VERY tiny pin hole drilled in them. This is going to shed oil out the sides of the crank. Not much as the holes are only a few thousandths but I wonder how that will effect oil pressure?

That's a little tighter than I would make it, especially with an aftermarket rod.
I prefer to not have parts make their own clearances by wearing metal away.
I would use a very good oil with that tight clearance.
I can try to loosen it but no way it would ever run this true again.

Crank trueness is irrelevant if the rod seizes, and it is certainly possible to get it to run at least close to what it currently is. This being said, I'm not saying that it will definitely seize, or that you should definitely widen the clearance, and it may be just fine, especially if you don't plan to rev the bejesus out of it, but I for one would seriously consider increasing the clearance as I would prefer to have a greater margin of safety if it was available to me.
