This, finally, is how it wil live. The only things missing in this picture are the oil pump drive gear and retaining ring (you can see the splines that hold the oil pump gear in place). Oh… and the whole bottom half of the crankcase is missing…
The retaining nut holding the flywheel flange in place needed to be small enough that it, and the socket that tigtened it, could fit safely within the ring of flywheel bolts. This meant using another bearing collar as a nut, since it's much more compact than a hex nut..
A couple more details had to be dealt with before we sealed up the case. This is the engine in its original form, sitting in place on a temporarily modified subframe. Draw a straight line between those two stel brackets on the subframe and you'll see where the steering rack has to go. The protrusion on the bottom is the lower engine mounting bolt and a mounting spacer, both of which thankfully just pull out.
Right above that is the bike's shifter, and above that, the drive sprocket. Both of those will have to be removed and their holes plugged.
The drive sprocket is replaced with this aluminum plug. A snap ring holds the plug in place, just as the output shaft's bearing was originally held in place. Magic grey case sealing schmoo handles all the sealing duties.
The shifter was attached to a complex sequential shift mechanism that left an odd-shaped hole. For now, we've just sealed this hole with a flat blockoff plate, but in the future we'll have to make a more complex plate with a dipstick hole, oil fill cap and turbo oil drain hose.
So that's it for now. Enjoy this peculiar view of a Hayabusa engine with a Miata flywheel. We'll actually be mounting the engine in the car next week, and we've even solved our starter problems, so I can promise you won't have to wait 9 months for the next update!
Oh, I almost forgot… 11,000 RPM!
All the Miatabusa you can handle:
