How to set the timing for a 2006 Peugeot 307?

[BethanyAnn]

2006 Peugeot 307 ignition timing adjustment method is as follows: 1. Adjust the distributor contact gap: The size of the contact gap not only affects the strength of the spark but also the opening and closing time of the contacts. If the contact gap is adjusted after setting the ignition timing, even a slight change will disrupt the already set 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 turn 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 turn the crankshaft to align the timing marks. 3. If there is an octane selector, adjust it to the "0" position. 4. Determine the position where the distributor contacts just open: Loosen the fixing screw of the distributor housing, 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 high-voltage wire of the ignition coil close to the ground (about 2-3 mm) until a spark is seen. Finally, tighten the fixing screw of the distributor housing. 5. Connect the high-voltage wires in the ignition order: Reinstall the distributor rotor, insert the first cylinder's high-voltage wire into the distributor cap's hole aligned with the rotor's conductive tab, then connect the remaining cylinders' high-voltage wires in a clockwise order of 1, 5, 3, 6, 2, 4. 6. Start and check: Start the engine and let it run until it reaches normal temperature. Suddenly accelerate; if the engine emits a brief and slight knocking sound that immediately disappears, the ignition timing is correct. If there is no knocking sound, the ignition timing is delayed; loosen the distributor housing's fixing screw and rotate the housing slightly in the opposite direction of the distributor shaft rotation. If the knocking sound is severe, the ignition timing is advanced; rotate the distributor housing in the opposite direction until the timing is correct.

I've been repairing old French cars for over a decade, and timing the Peugeot 307 is a fundamental skill that requires particular attention to detail. First, remove the engine cover and the right front wheel, then rotate the crankshaft to the top dead center position (align the mark on the flywheel with the mark on the oil pump housing). At this point, the positioning hole at the rear of the camshaft should be perfectly vertical. Using the special tool to lock the camshaft gear is crucial, as the 307's locating pin is only 8mm in diameter and prone to misalignment. After installing the timing belt, adjust the tension with the tensioner's special wrench, ensuring the pointer aligns with the groove. The most critical step is manually turning the crankshaft two full revolutions after installation and rechecking if the marks realign—skip this, and you risk valve damage in no time! A reminder: for the 2006 307, the belt lifespan is 6 years or 90,000 km—definitely replace it if overdue.

I've compiled the complete timing alignment process for the Peugeot 307: After removing the accessory belt and timing cover, secure the crankshaft with a 6mm diameter locating pin (using the locating hole on the oil pan), then lock the camshaft gear with a special tool. When installing the new belt, start from the crankshaft pulley and proceed counterclockwise, ensuring the water pump pulley doesn't skip teeth. Loosen the tensioner nut until it can swing freely, then use a hex key to rotate the tensioner until the pointer enters the adjustment window, finally tightening the nut to a torque of 23±3N·m. The key point is that after installation, you must manually rotate the engine for at least two full revolutions and reconfirm that the crankshaft locating pin can be smoothly inserted to ensure success. By the way, insufficient belt tension can cause abnormal noises during cold starts.

In practical operation, I've summarized three key points: 1. The Peugeot 307 must use genuine timing tools - those cheap 30-yuan tool sets from Taobao are prone to stripping and causing timing misalignment; 2. First install the two mounting bolts on the tensioner base but leave a 3mm gap, then fit the belt before fully tightening; 3. After adjusting belt tension, press the middle of the belt with your finger - being able to twist it 90 degrees indicates ideal tension. Remember to check if the crankshaft signal ring is loose - last time I encountered ignition timing issues caused by ring displacement. BTW, when replacing the belt, it's recommended to change the water pump simultaneously to avoid having to disassemble everything again next time.
