Fit the spinner
Fit the spinner using 5/32” countersunk screws and Tinnerman washers.
Use a long sanding block to sand the rear mounting plate flush with the rear of the spinner.
Reassembly
Refit the spark plugs – refer to the engine manual for the torque settings. Remember to fit the
CHT sensor under the left rear spark plug.
Refit the spark plug leads. Each cylinder pair can only be fitted to the correct cylinder.
Push each spark plug cap until it clicks fully home onto the spark plug end.
Refit the ram air cooling ducts: fit and tighten the tappet cover screws and clip the spring
retainers to the cylinders.
Check that everything inside the cowling is as it should be – all wiring secure, hose clamps
tight, scat hoses all tight, etc.
Refit the top cowling. Fit the piano hinge pins first. The cowl fittings come in 2 lengths: the 3
shorter ones go across the rear of the cowling while the 2 longer ones go each side of the prop
hub.
This completes the
