180MK STINSON 180HP MINIMUM KIT

This kit is made to order. Typical assembly time is 1 week if all parts are in stock.

Lycoming O-360 Series - 180hp

Our STC covers the installation of the O-360 series* 180hp Lycoming engine with fixed-pitch Sensenich propeller for the entire 108 Series of Stinsons. The 3/8 inch fuel lines in the 108 and 108-1 will have to be replaced with 1/2 inch fuel lines. This will require a modification of the fittings on the fuel tanks. Univair can supply all the necessary 1/2 inch fuel line components with the exception of the fuel valve. Also, the 108 and 108-1 will require the Rudder Bungee Kit if not already installed. Neither the fuel lines or Rudder Bungee Kit are included in the Minimum Kit; they must be purchased separately from Univair. The 108-2 and 108-3 already have 1/2 inch fuel lines. The 108-2 will also have the Rudder Bungee Kit already installed. The 108-3 does not require the Rudder Bungee Kit as it has a rudder with a pilot adjustable trim tab.

This engine conversion will allow the use of the existing cowling requiring some modifications to the nose and lower cowl.

Below are lists of major items that we require as a minimum of purchased parts from Univair. These Minimum Conversion Kits will be sold only as a complete package. Other "detail" items are needed for the installation. However, they may be purchased individually or from other vendors. These include items such as controls, ducting, hoses, etc.

Note: In developing this STC installation, Univair used the narrow (standard) deck engine. Installations using the later wide deck engines may require minor modifications to the baffling.

*O-360 engines approved for this STC are O-360-A1A, -A1D, -A1F, -A1F6, -A1F6D, -A2A, -A2D, -A1AD,-A2E, -A2F, -A3A, -A3AD, -A4AD, -A4M, and -A5AD
