Remove the timing chain

Step 1: Set the No. 1 cylinder to TDC/compression

Firstly, you need to set the No. 1 cylinder to TDC (Top Dead Center)/compression. This will ensure that the piston of the No. 1 cylinder is at the top of its compression stroke when you remove the timing chain.

Step 2: Turn the crankshaft pulley clockwise

Turn the crankshaft pulley in a clockwise direction and align its groove with the timing mark "T" on the lower timing chain cover. This will ensure that the crankshaft is in the correct position before you remove the timing chain.

Step 3: Check the alignment of the camshaft timing sprockets

Check that the marks on the camshaft timing sprockets are in a straight line on the cylinder head surface. If they are not aligned, turn the crankshaft clockwise by one full revolution (360°). Do not rotate the engine in a counterclockwise direction.

Step 4: Remove the timing chain cover

Now, you can remove the timing chain cover. Be careful not to damage the contact surfaces of the cylinder block, cylinder head, and timing chain cover. It is important to keep these surfaces intact to prevent oil leaks and ensure proper sealing when you reinstall the cover.

Step 5: Mark the RH/LH timing chain

Before removing the timing chain, use an identification mark on the RH/LH timing chain based on the location of the sprocket. The identification mark on the chain for TDC may be erased during the removal process, so creating your own mark will help you realign the chain properly during installation.

Step 6: Remove the oil pump chain cover and tensioner assembly

Remove the oil pump chain cover and the oil pump chain tensioner assembly. To release the ratchet, pull the link down using a thin rod, then compress the piston and insert a stopper pin to hold it in place.

Step 7: Remove the RH timing chain components

Remove the following RH timing chain components in the order listed:

• Cam to cam guide
• Auto tensioner
• Tensioner arm
• Guide
• Timing chain itself

Step 8: Remove the crankshaft sprocket and oil pump chain components

Remove the crankshaft sprocket that drives the RH camshaft. Then, remove the oil pump chain sprocket and the oil pump chain. To release the ratchet for the oil pump chain, use the same method as in Step 6.

Step 9: Remove the LH timing chain components

Remove the following LH timing chain components in the order listed:

• Cam to cam guide
• Auto tensioner
• Tensioner arm
• Guide
• Timing chain itself

Step 10: Remove the crankshaft sprocket for the LH camshaft

Remove the crankshaft sprocket that drives the LH camshaft.

Step 11: Inspect and replace components as needed

At this point, you have removed the timing chain and related components. Before proceeding with reinstallation, inspect the sprockets, chain tensioner, chain guide, and tensioner arm for abnormal wear, cracks, or damage. Replace any components that show signs of excessive wear or damage.

Step 12: Support the engine and align the crankshaft

Install a jack to the edge of the upper oil pan to support the engine. Insert a rubber block between the jack and the upper oil pan to prevent damage. Align the key of the crankshaft with the timing mark on the block. This will ensure that the piston of the No. 1 cylinder is at TDC on the compression stroke.

From here, you can proceed with the reinstallation of the timing chain and related components, following the reverse order of removal and torquing specifications provided in the service manual.
