Timing Chain and Sprocket Removal Camshaft

Important: 

•	Ensure that the timing marks are correctly aligned before disassembly.

•	Do not turn the camshafts and the crankshaft once the timing chain is removed. Valve and piston damage may occur.

1. Hold the camshaft with a wrench and remove the camshaft sprocket bolts (1).



2. Remove the camshaft sprockets and chain.
3. Inspect the following components for wear and damage:

•	The camshaft timing chain upper guide

•	The camshaft timing chain tensioner

•	The camshaft timing chain sprockets

•	The camshaft timing chain

4. Replace damaged components as necessary.

Timing Chain and Sprocket Removal Crankshaft

Important: 

•	Ensure that the timing marks are correctly aligned before disassembly.

•	Avoid turning the camshafts and the crankshaft once the timing chain is removed. Valve and piston damage may occur.

•	If necessary, the camshafts may be turned 15 degrees from the marks on the cylinder head in either direction.

•	If necessary, the crankshaft may be turned 90 degrees from the mark on the engine block in either direction.

1. Remove the 2 bolts and the crankshaft timing chain tensioner (3).
2. Remove the 2 bolts and the crankshaft timing chain fixed guide (2).
3. Remove the bolt and the crankshaft timing chain adjustable guide (1).
4. Remove the idler sprocket and the crankshaft timing chain.
5. Remove the crankshaft timing sprocket.
6. Inspect the following components for wear and damage:

•	The timing chain fixed guide

•	The timing chain adjustable guide

•	The idler sprocket

•	The crankshaft timing sprocket

•	The crankshaft timing chain

7. Inspect that the latch and teeth of the crankshaft timing chain tensioner are undamaged and that the tensioner functions correctly.
