Introduction
This tutorial shows you the steps to change the timing belt kit of your Peugeot. The model presented in the tutorial is a Peugeot 306 1.8 16V phase 3
-
-
Lift the hood.
-
Disconnect the negative terminal of the battery.
-
Loosen the 2 clamps and the nut behind them.
-
Remove the air filter.
-
-
-
Securing the vehicle: removing and refitting the wheel -
Remove the front wheels and place the vehicle on jack stands.
-
Keep your jack so you can raise and lower the engine later.
-
-
-
Don't forget to place a jack with a wooden block under the engine to support it once the engine mount is removed.
-
The bracket is fixed by 2 BTR screws and 3 nuts.
-
-
-
Using a 1/2 square, loosen the accessory belt and then remove it.
-
Mark the routing of the accessory belt before removing it.
-
-
-
Unclip the hoses at the locations indicated by loosening the hose clamps and pulling gently on them.
-
Remember to place absorbent paper or rags under the hoses to wipe up any fuel that leaks out.
-
Once unclipped, remove the hoses from the timing cover.
-
-
-
Upper timing cover
-
Fish BTR
-
Ecrous 10mm
-
Loosen the screws and nuts and then remove the housing.
-
When reassembling, make sure that the 2 "feet" of the casing are properly fitted together.
-
-
-
Your vehicle must be in neutral.
-
Rotate the engine clockwise by the crankshaft pulley screw until it reaches the pegged position (12 o'clock).
-
Never turn the engine counterclockwise.
-
Once the Damper pulley pin hole is aligned with the one in the engine block, pin it with an 8mm pin.
-
-
-
Since the crankshaft is pegged, the camshafts must be in the correct position. All that remains is to install the 6mm pins.
-
-
-
We now know that the engine is in the correct position.
-
After locking the flywheel, you will need to loosen the crankshaft pulley screw, hence the need to remove the pins.
-
-
-
This step will prevent any rotation of the engine when loosening the crankshaft pulley screw.
-
Some people use a large flathead screwdriver, it is safer to use a more suitable tool.
-
To lock the flywheel you need to insert the teeth of the tool into the teeth of the flywheel then secure the tool by inserting a 6mm bolt and tightening the nut hard enough so that it does not loosen.
-
Another method if there are 2 of you is to shift into the highest gear and press the brakes very hard to prevent the engine from spinning.
-
Never attempt to lock the crankshaft pulley with a drill bit or pin in the timing hole.
-
-
-
You can now loosen the crankshaft pulley screw.
-
Once loose, remove the pulley.
-
When reassembling it is essential to use a new screw.
-
-
-
Loosen the 4 screws using an Allen key then remove the housing.
-
-
-
This step is not mandatory, however if you are unsure it will help.
-
Make marks with white on your belt as well as on the crankshaft and camshaft wheels.
-
-
-
Replace the crankshaft pulley and its screw.
-
Do not overtighten the screw.
-
Replace the 3 pins.
-
-
-
It is not easy to access, you need a 13 key to loosen.
-
Once loosened, remove the tensioner roller.
-
-
-
Now that the roller is removed, your belt is completely relaxed, you will have no trouble removing it.
-
-
-
Reassembly is carried out in reverse order.
-
Copy the markings from the old belt onto the new one.
-
Match the marks on the new belt with the marks on the pulleys.
-
To adjust the tension you do not need any specific tool since the tensioner roller is automatic. The tension is correct when the needle is between the 2 marks. To do this, take a 6mm BTR key and apply an anti-clockwise rotation until the needle is correctly positioned then tighten the screw to the prescribed torque.
-
Remember to use a new crankshaft pulley screw and tighten it to the specified torque.
