Where is the timing installation point for Jiangling JX493ZLQ3?

[LailaFitz]

There is a small notch at the 12 o'clock position of the crankshaft timing gear, a small protrusion at the position of the 4th cylinder, and a small notch on the camshaft timing tooth surface. There is also a small notch fixed with a screw from top to bottom on the camshaft timing tooth surface, and the same applies to the high-pressure pump timing tooth surface. After seeing the screw hole below, fix it with a screw in the same direction. Below are the specific steps for ignition timing adjustment: 1. Adjusting the distributor contact gap not only affects the spark strength but also the opening and closing timing of the contacts. If the contact gap is adjusted after setting the ignition timing, even a slight change will disrupt the ignition timing. Therefore, the contact gap must be adjusted before setting the ignition timing, within the range of 0.35 to 0.40 mm. 2. Locate the top dead center position of the first cylinder's compression stroke and loosen the first cylinder's spark plug. Slowly rotate the crankshaft until a hissing sound is heard, indicating the first cylinder is in the compression stroke. Open the inspection hole cover on the flywheel housing and slowly rotate the crankshaft to align the timing marks. 3. If there is an octane selector, adjust it to the 0 mark position. 4. Determine the position where the breaker contacts just begin to open. Loosen the distributor housing fixing screw, rotate the housing in the direction of the distributor shaft rotation to close the contacts. Then turn on the ignition switch, rotate the distributor housing in the opposite direction of the distributor shaft rotation while holding the ignition coil high-voltage wire near the ground (about 2-3 mm) until a spark is observed. Finally, tighten the distributor housing fixing screw.
