There was no machineing done on the crank so all of the journals are std (I know for a fact). So the machine shop ordered Clevite 77 std size bearings for it.

Subaru bearings don't go by .010", .020", 0.30" over sizes like american cars do.

What you do is mic the journals and look up the reading you got on a list thats in the manual and it will give you the bearing size to use on that journal. Their bearing sizes are oversized by less than a .001 So say you measured a journal and the reading you got was 2.0275mm. You look up on the list where this measrment falls and it will tell you what undersize bearing(if needed) you need to get so it will be within specs. Thats it no machining. I quess thats assuming that the case or rods are in good shape and don't require machining.
I think honda and a few other imports use this method.
The only thing I can figure out why they do it this way is that maybe not all of the cranks are machined the same at the factory and they use this method to get the crank and rod in specs.

Well the rebuild has stalled out.

The subaru Dealer had to call Subaru USA to get the right part numbers for the main bearings so those are on order and the machine shop is replacing the rod bushings(that they should have done in the first place). Subaru has discontinued the bushings so the machine shop will have to find a supplier for them. If someone brought in an engine for rebuilding and the rods were there, don't you think you would at least check the rods out???!!??. I give up, at least here in vegas. everyones lazy and doesn't want to do their job but wants to get paid big bucks for doing nothing and if they do something the quality is way below what it should be. At least the Subaru guys gave me a break on the price for the bearings. You guys better sit down for this one. They got me for $350 for rod and main bearings. I need to start carrying vasaline around with me. This motor rebuild is not going to be cheap. It'll be in the $2000 range I fear. Thats still not to bad for a blue printed engine.

I wonder what a crate motor would be from Subaru? No, it wouldn't be blueprinted, but at least it would be zero mile..

More bad news. The machine shop cann't locate bushings for the rods and the dealer cann't get them either.
My choices are to use what I have or get new rods. I searched the internet and came up empty.

OK here's whats going down.
In the Subaru service manual they have two measurments. One is std tolerances and the other is the service limit. The rod bushings are 0.0001 out of std tolerances but are not at the service limit so I'm going to use them as they are.
With that being said the cases are back together and tomorrow I'll check the pistons and rings and if everything is a go there I'll install them and the rebuild will continue.
I talked to the machine shop that did the work on the engine and they commented that they don't put together engines with these tight of tolerances. The reason I mention this is because there is no play hardly at all in this motor. Crank and rod bearings are all at 0.001 or less but thats factory specs.

I'm leaving out alot of posts of this rebuild because I assume everyone here knows how to rebuild an engine and this is mostly to show the progress only. There are thousands of books out there that cover rebuilds and everyone has their own way to do things.

Rods are stamped with what cylinder that they came out of.(do this before you remove them)

Rods have a front and back. Mark on rod points to the front

Back side of rod has no marks

Pistons are mic'd for what cylinder they will go in

Ring gap is checked on all rings

Oil Pump is checked to see if its with in limits

Once oil pump is checked and passes specs it is packed with assy grease so it with pick up prime faster than if left dry.

Head bolts are tightened per factory specs
