609100 ASSEMBLY - CRANKCASE UPPER HALF is complete and posted to GrabCAD!!

 Hey guys, welcome back with big news.  The upper crankcase assembly is complete!  I've been working on it for a year now, almost to the day.  If you want to be technical it'd be a year and 4 days, but who's counting?

Here's a few renders of the completed assembly first.




It may not look like a ton has changed since the last update, but I've added in the timing marker that mounts to the No.1 main bearing cap. It's to help align the crankshaft with TDC (Top Dead Center of the number one piston) during assembly.


Something most Rolls Royce made Merlins do not have is this lifting eye, which was next on my list.  This is exclusive to the Packard and Continental Merlins.


Next I modeled this cool little banjo fitting. I don't know why I find it cool, I just do.


There are two of these used on the oil supply to the variable pitch propeller mechanism.  These attach to the top front of the reduction gear housing. I'm not sure if they are turned right, yet, I'll have to figure that out later as I model more parts.


The last major part to be added was the main oil supply pipe.  The oil pump pumps oil out to the oil pressure regulator which mounts to the side of the crankcase.  The oil then pumps back into the case and through this pipe to be distributed to all the main bearings.


Here's what it looks like mounted.


Well, that's about it.  You can click here to download the complete assembly in SolidWorks native, Parasolid, STEP, IGES, and STL. You can download the files here.

 I am on to the next assembly, which will be the lower crankcase assembly, a.k.a. the oil pan. I'm still looking for a job, so if you like what you see, maybe pass my name on to your friends who might be in need of a CAD jockey. Hope you guy's are having a good day.

Something something studs

 Not a huge update so first I'll post a couple of images of the current progress, then we'll get into the meat of the post. So, the astute follower might notice that the assembly has gotten a lot more studly.  Studs have taken up the majority of my time over the last few days, 25 of them to be exact. Other than that I did the main bearing caps. There are three different part numbers but two of them are the same with minor differences. 620792 and 620793 are practically the same part except 620793 has two small holes with spotfaces in the front for the timing marker. 620793 is the No. 1 bearing cap, while 620792 is used for almost all the rest of the caps except No. 4. The No. 4 cap is 601423 and it's a bit beefier. Or maybe you'd call it a bit studlier. bah dum bum tsss

THIS BEAST IS COMPLETE!!!!

 I've finished doing all the machining operations on 618110; CRANKCASE - UPPER HALF, which means the part is finally complete. I feel like that's an odd thing to say after almost a year of work.  To wrap it all up in just a couple weeks feels a little bit off to me.  But it is what it is. And, at the very least, what it is is complete. :D Again, I've highlighted all the operations I've done in this part in blue so if it is blue, then I have "machined" some material away there. Aside from about 300 - 400 holes, there was the bearing seats, a bunch of spotfaces, and the mounting pads were very thick as cast. The cross section being blue was a result of how I did the materials in the part to make it easy to highlight the machining operations.  It'll go away when the rest of the blue does. It just struck me as I was doing the screengrabs for this page but there are no cooling passages in this crankcase.  I mean I realized they had huge oil coolers to do the co...
