@K7AAY - You've probably noticed I've edited and reopened your question. I think it's more viable now, as it asks a specific question. You are looking for information on removing/replacing the turbo. Now the question asks that specifically. I hope this doesn't go against your intent.
@BobCross @Bob Cross: No, I will unbolt the old assembly and replace it with one acquired from ebay motors if unable to find a rebuilder here in Metro Portland OR
@Pᴀᴜʟsᴛᴇʀ2 That's basically what I build, but I'm using an ACME trapezoidal lead screw instead of a ball screw. (Ball screws are significantly more expensive.)
Weird - that page doesn't say how long it is, unless I've lost my ability to read.
In other off-topic news (not sure if I mentioned this already): The window AC unit in my shop, that I installed through a wall in the back so it'd be a little less trashy-looking, was clogged up with wet sawdust, MDF dust (that stuff is not fun to clean up).
Fixed it; now the shop gets cold. Tinting the west-facing french doors and windows also helped.
I was making some hold-down clamps this morning on the CNC, and the cable for the Z axis got stuck on the back side of the table, ripped some insulation, and grounded itself against the frame. I need to re-do all the cables, anyway.
@3Dave - Magnets on the flywheel? That will give you engine speed, not clutch disk speed. And tail shaft speed will get you clutch disk speed as long as the transmission is not in neutral. Once in neutral, all bets are off.
