If the secondary timing chain is removed to remove the injection pump, see the preparatory work in the section above "Electronically controlled injection pump".
If the secondary timing chain is removed to remove the camshaft, see the section below "Camshafts".
1. Remove the front chain cover.
Remove the power steering fluid reservoir from the bracket.
Loosen and remove the mounting bolts in the reverse order to that shown in the illustration.
Since there is little space to remove bolts 6, 10 and 11, remove these bolts together with the rubber washers.
Attention:
When removing the front chain cover, cover the open holes to prevent foreign particles from entering the engine.
Do not remove the dampers installed on the back of the cover (in two places).
2. Set the piston of the first cylinder to the TDC position of the compression stroke.
Turning the crankshaft clockwise, set the marks on the camshaft sprockets in accordance with the figure.
Note:
There is no timing mark on the crankshaft pulley.
The installation of the secondary timing chain is done by aligning the colored links, so there is no particular need to apply marks before removing the chain, however, due to the fact that the marks on the fuel injection pump sprockets are difficult to see, it is better to apply marks.
3. Remove the chain tensioner.
Shoot in the following order.
(1) Press the plunger and secure it with the pin.
(2) Loosen the mounting bolts with a hex key (special tool, 5 mm).
4. Remove the chain guide at the bending point.
Loosen the mounting bolt using a hex key (special tool, 6 mm, short) and remove the chain guide.
5. Remove the chain guide at the tension point.
6. Remove the secondary timing chain.
The chain can be removed without removing the sprockets.
