Crankshaft timing gear marking
The marking of the crankshaft timing gear is indicated by an arrow.
Selection of crankshaft gear
1 – camshaft gear; 2 – crankshaft gear; a – nominal clearance; b – the gear is shifted inward; c – the gear is shifted outward
Crankshaft timing gears for 1.0L 37 kW and 1.4L 50 kW gasoline engines are supplied as spare parts in three width sizes, differing by 0.2 mm. The gears are marked with the letters E, F, and G, which are stamped on the gear hub above the keyway, as shown in the figure. When replacing, you need to install a gear with the same markings as on the old one. Otherwise, the chain may jump off when the engine is running.
1. Install the timing gears onto the camshaft and crankshaft. Press them axially and apply a rigid ruler to the camshaft gear as shown in the figure (the arrows indicate the marks).

2. Measure the gap using feeler gauges (see figure Selecting the crankshaft gear) between the ruler and the crankshaft gear. The nominal gap should be equal to (0.11±0.18) mm.
3. If the measured clearance differs from the specified one, a gear of a different width must be installed.
