So...six of one and half dozen of the other? 😆
The bearings I removed are Japanese so I think they’re original.
The breather nipple on the 72 is beneath the cam housing, not on the rear cover so I think the pumping action from the piston is sufficient to move oil through a metal shielded bearing.

Interestingly i have had bearing distributors tell me the bearings will service the same lifecycle or better installed with the sheilding in place. Both opine the factory installed lubricant will service the bearing for the life of the bearing.
i remove the front shield of the rear main bearing and run em. At 12% lube. Have not had a re-failure of a boca stainless steel bearing yet. 5 years running.
Hey Gary
Got any open time for a pick up of that Waco this weekend? I need to irritate my lovely wife with another "stupid" plane coming home in her Subi....lol

hey guys, here's a thought on cam lubing on a Saito.
you would have to have 3 hose barbs tho. one barb on the back plate, and 2 somewhere around the cam area. one of those 2 barbs should point at the cam. run a hose from the back plate to the barb that is pointing at the cam, the 3rd barb would be the breather. this way you would not need flapper valves .
hummm, maybe use a new case/or engine with the breather on the bottom / front behind bearing, buy an older back plate that's drilled and tapped for a breather, then you would only have to drill and tap for the barb that points at the cam. slick.
what you think.
see, I told you I was a genius

Well, that $20 power supply from Amazon works perfectly for the Sherline CNC. Got it fired up for the first time since I got it 8 years ago. All 3 axis work perfectly, now to figure out how the heck to use it, but first need to get the server on my network so I can run some updates and make sure I can access the box remotely. I plan to enclose the server in a dust proof box and run it from my laptop via a remote desktop session. I also need to download Lightburn into it and figure out a way to connect it to the Laser so I can access it remotely as well.

I think the latest OS fourstrokes use a smart design for venting ie connecting a single vent output from the cam area to the intake pipe.
Boy did I just get delivery of a pos fa91. Price was too good to be true I guess. Not everyone on the rcg classies is honest or even fair. The guy who sold it is a real piece of work and very dishonest. PM me if you want to know who to steer clear of.
Spent the day getting the PC set up for the CNC. First, tried to install Lighburn for the laser. Turns out the OS for the Sherline software is 32 bit, the laser software is 64 bit. Wont run. I download the install for a 64 bit OS, need to burn it to a DVD. Well, my laptop doesn't have one, and come to find out my portable one stopped working. Spent at least 3 hours futsin around trying to get it to work and finally dug out my old windows 7 PC which has a DVD writer on it, and was finally able to make a boot disk. Got the OS installed, Lightburn is installed and works, Now trying to get the LinuxCNC software to install. In the meantime, it had to do updates, so have to wait for those to finish.
I do this every day for a job, I really don't want to do it at home, so now you know why it sat 9 years before I finally got around to it.

in the 2nd photo you can see the plugs and how short the flange was cut.

Jim, it seems to me that without a check valve(s) all the vents would see the same positive and negative pressure changes at the same time. If that's the case then there would be nothing to make the oil move from one vent location to another.

I see what you mean there about not using the valves. without valves it would just suck air from the vent because air is lighter then oil. as for the OS setup, that was how that Magnum 180Fr was setup.

I think Piglet got a longer scarf than the Panthers, he sure looks good. Douglas is looking into making a Albert Ball bust for another expat Englishman who lives farther south in France. I'm anxious to see how it turns out. I hope Douglas is having as much fun with his handy work as we are!
