Thanks and I agree. It’s only shiny and new once! I can’t wait to get this monster bolted together and get some complete pictures.

Oooooooohhhhh..... shiny sparkles....the crank is here....

 

[Hemirunner]

It’s a real nice piece.

It’s got a 1” slug of Mallory up front

And a little one out back

That looks like a sweet piece

The beauty of machined steel.

I like the chamfering on the on the oiling holes, looks great.

Thanks. It’s the nicest forged one I’ve ever used.

The beauty of machined steel.

Even the counterweights are fully machined on this one.

yeah, they did a nice job of that. It’s a real nice piece.

Managed to clean up the work bench so I could gap some rings...

Bearings should be here next week. I went with Calico coated Clevite H-series bearings. Ended up with .0028” on the rods and .0035” on the mains.

Did some cleaning myself tonight. Looking good there.

If you can stay with cool oil and lots of it all the better as mains are close to max clearance

It’s a dry sump system with an adjustable pressure regulator. I ordered the crank with the main journals at 2.7495 to get this kind of clearance with the housing bore at the low end of the spec which when hot, should open up the clearance to .004-.0045. The main thing is to not lose clamp load on the insert.

Did a little ring gapping last night. Top ring and second ring at .035 gap. Top ring is an AP Steel and the 2nd is a ductile napier.

The first time I read the clearances on Aircraft crankshafts I was concerned
With the dry sump and cool oil all is good

 

[Hemirunner]

Rod bearings showed up.

Secret coating?

 

[Hemirunner]

Secret coating?

Yes!! I should not have posted pics of these top secret bearings! Lol. It’s just Calico’s CT-1 dry film coating. It’s purpose is to minimize the damage if for some reason we have an oil issue. Hopefully it would keep the bearing from spinning in the bore. I have a set of mains coming from them as well. They’re Clevite H Series bearings.

All the rings are gapped and on the corresponding pistons.

Oil squirters are in and so are the block plugs

Need to cut some valley screens and epoxy them in.

 

[Hemirunner]

Main bearings showed up. At least the first set. I ordered a coated set of MS1277HGs so I could have a larger diameter thrust bearing.

Had to take a break and put some cabinets in the front garage.

Now to get the ugly stuff off the shelves and hang some slatwall.
