TYPE 1 - FLYWHEEL DRIVE!

Great Plains Aircraft Flywheel Drive Package uses the same high quality components offered in our front drive, rear drive and reduction drive engine kits. The crankshaft is forged, balanced, nitrided, shot peened, precision ground and micro polished from a virgin blank of E4340 steel (in the 2180cc kit).In the 1835cc and 1915cc, we use stock 69mm VW crankshaft made from a 1045 steel forging.

The engine case is a new dual by-pass case with all required machine work completed. The case is opened for 92 or 94mm cylinders, clearanced for 82­84mm stroke, drilled and tapped for #4 oil feed and has the reinforcement plate welded to the right of the rear main.

The connecting rods are balanced, bushed, sized center to center for length and cleared for stroker cranks, if needed. The camshaft has been selected to provide the maximum torque at the rpm we use the engine at in aircraft. The pistons are forged, balanced and graphite coated by Cima Mahle, new heads, valves etc and you're almost ready to go!

Why Flywheel Drive?

The flywheel drive drives the prop off the #1 main bearing. Many builders consider this the correct way to drive the prop on a VW (it's only one of four ways and we can't say one is better than another). It offers a lighter engine at 158 lbs., and the least expensive way (the 2180cc single ignition engine kit is $4574.30) to drive the prop on a VW engine. Even with the oil pump secondary ignition, it is the Lightest and Least Expensive 76 HP VW conversion offered in the market today! You can add the Nikasil Aluminum Cylinders for $600 and save 10.2 pounds!

(Note: when set up for a pusher - the flywheel shims remain between the flywheel and the #1 main bearing. When used as a tractor the end play shims are moved between the crankshaft and the #1 main bearing.
