Notes

A ring clamped between the cross's top face and the port cap, like a thick gasket, each side its own Type B gasket and clamp. Its Ø30 bore lets the gas and the motor's three leads through to the port cap.
From the ring a column hangs down the cross's top run to a mount face 62.1 mm below the plate. The motor's base bolts to it with four M3 × 6 countersunk screws whose heads sit flush, because the top run leaves no room for heads behind the face. The holes follow the motor's 16 and 19 mm pairs, turned 45° so the face stays inside the Ø47.5 bore.
Everything stays inside the bore and inside the gasket lip (Ø45.3) where it passes the joint. The motor hangs over the crank, its axis parallel to the crankshaft, its pinion in mesh with the crank gear.
