Engine control system

Transmission

The transmission is located at the rear edge of the engine on a 6 mm thick steel plate, which is screwed to the cylinder head and engine block, and fixed with two guide sleeves and a guide pin. All wheels are angle-cut and nitride hardened. The crankshaft gear (5) also works as a spacers between the crank shaft flange and the flywheel. It is screwed on with 12 ea pass-through screws and fixed to the crankshaft with two socket head cap screws and a guide pin. Above the crankshaft wheel is a dual wheel (3) consisting of two gears screwed together. The wheels are pre-installed on a hub journalled in two conical roller bearings. The inner wheel drives the upper (adjustable) intermediate gear (2) which in turn drives the camshaft wheel (1) and is journalled in a bushing on the hub. The backlash shall be adjusted between the upper intermediate gear (2) and the camshaft wheel (1) when the transmission has been serviced. 1. camshaft drive 2. upper intermediate gear 3. dual drive 4. lower intermediate gear 5. crankshaft drive 6. oil pump drive wheel 7. fuel pump drive wheel/servo pump

Camshaft wheel (1) is screwed into the camshaft flange and controlled by a guide pin. The vibration damper with teeth for the camshaft sensor is installed on the outside. The lower intermediate gear (4) is journalled in a tworow ball bearing and drives the combined fuel pump/ servo pump. The wheel is fastened with a screw that runs through the flywheel casing and is threaded into the cylinder block. Drive wheel (7) is installed on the servo pump passthrough shaft, which drives the fuel pump. The oil pump drive wheel (6) is powered by the crankshaft gear.
