Ring Gear Replacement

Arrangement Engine 116.96, 117.96 (3rd version):

16 Plates
17 Driven plate 1.5 mm

19 Necked-down bolt
20 Ring gear
21 Bolt

NOTE: When removing the transmission the ring gear remains on the engine.
The ring gear (20) with 4 segments for the position indicator of the ignition system is forged from one piece, balanced and bolted to the driven plates (17) and (18).
The 1.5 mm thick driven plate outer diameter is a machined fit for the centering of the ring gear.





When removing the ring gear unscrew the position sensor (3) and pull it out of the bracket (1) 50 that it is not damaged.





NOTE: The ring gear must be installed so that the 3.5 mm dia, holes (arrows) in the ring gear and in the driven plates are at the same angle otherwise proper operation of the ignition is not assured.
