We take a little time to install the fuel flow divider. This one looks a little different than the usual Precision Airmotive divider because it is part of the FADEC system. It is not the simple chamber with 4 tubes running out of it.
It's time to torque the case through bolts (30 foot pounds) to bring the case halves together.
The last of the case bolts (and nuts) are added on the case bottom. Because these are not visible for inspection once the oil sump is installed, these will have to be safety wired before everything is closed.
They are through-bolts, so they have to be torqued on both sides of the cases.
Now it's time to get the motor back into the upright position. I'm wondering if that block and tackle is strong enough, but Kirk has no doubt.
Yeah, it seems to be holding. But, what if it doesn't?
Rubber o-rings seal the bottom of the cylinders when they are attached to the case. No, they don't go around the piston...
Plenty of lube is applied to the wrist pin bushings.
The lube is smeared evenly on all the bushings.
The cylinder (with the piston and rings already installed) is held up to the case and the wrist pin is pushed through the bushing at the rod end. The nuts are screwed onto the bolts and the cylinders find a home.
I just had to peek into an intake port and look at the valve and honing done to flow match the cylinders.
Kirk continues to inspect my work. I have mixed feelings, I don't want him to find anything wrong, but if there is something wrong, I want him to find it. So far, so good.
The cylinders are installed and we use this nifty bent wrench to torque the cylinders to the case. The small cylinder bolts are torqued to 30 foot pounds and the large ones to 30 and, in a second round, to 50 foot pounds.
