What's Inside the Manual

This documentation provides a complete breakdown of the construction, overhaul, and testing procedures for these four-cylinder, air-cooled aircraft engines. It covers major sub-assemblies in detail, including crankcase construction, crankshaft specs, and valve mechanism adjustments. You will also find comprehensive sections on gear train timing, lubrication pathways, induction system maintenance, and ignition configurations for both Bendix and Slick magnetos. Factory instructions for unpacking, shipping, and long-term storage preservation are included as well.

Specs & Tolerances

The manual contains the exact technical data needed for accurate engine assembly and precision measurement. Highlights include intake valve clearances for lifters (.030–.110 inches), connecting rod bolt torque values, and oil system capacities (ranging from 4 to 6 U.S. quarts, depending on your configuration). It also outlines specific build specs, like the 3-7/8 inch piston stroke for the higher-compression C90 and O-200 models, and the 6.3:1 compression ratio for the C75 and C85.
