Timing Chain Tensioner Removal Camshaft
- Remove the spark plugs in order to make rotating the crankshaft
to line up the timing marks easier.
Important:
• | Align the timing marks before disassembly. |
• | Do not turn the camshafts and the crankshaft once the timing chain
tensioner is removed. Valve and piston damage may occur. |
- Rotate the crankshaft so that the following conditions are met:
• | The number 1 (frontmost) cylinder is at the top dead center (TDC)
position on the compression stroke. |
• | The keyway on the crankshaft (5) aligns with the mark on
the engine block (4). |
• | The arrow (3) on the idler sprocket is pointing upward. |
• | The guide pins (1) on the camshaft sprockets line up with
the notches (6) on the cylinder head. |
- Relieve the tension on
the camshaft timing chain by turning the intake camshaft slightly counterclockwise.
- Remove the nut and 2 bolts (1, 2).
- Remove the camshaft timing chain tensioner.
- Inspect the camshaft timing chain tensioner for wear, damage and
correct operation. Replace as necessary.
Timing Chain Tensioner Removal Crankshaft
Important:
• | Ensure that the timing marks are correctly aligned before disassembly. |
• | Do not turn the camshafts and the crankshaft once the timing chain
tensioner is removed. Valve and piston damage may occur. |
- Remove the 2 bolts (1)
and the crankshaft timing chain tensioner.
- Inspect that the latch and teeth of the crankshaft timing chain
tensioner are undamaged and that the tensioner functions correctly. Replace
as necessary.
