- Engine underbody protection and left mudguard
- Front exhaust pipe
- Disconnect the right drive shaft from the transfer case side and move it to the side
- Intercooler
- Engine cover
- High pressure fuel pipes
2. Disconnect the two fuel hoses from the high-pressure fuel pump.
Remove the eye bolts and hose connectors.
Apply paint marks to the hose and fuel pump connectors so that they can be installed in the same directions later.
3. Disconnect the electrical wiring connector from the fuel injection pump.
Pull the locking mechanism completely out and remove the connector.
Note: If you pull the latch all the way out, the connector will move and come loose, but if you insert the connector about halfway and press the latch until it clicks, the connector will snap into place.
4. Remove the rear fuel injection pump bracket.
5. Remove the front chain cover.
Move the power steering fluid reservoir away from the bracket.
Loosen and remove the mounting bolts in the reverse order to that shown in the figure.
Since the space for removing bolts 6, 10, 11 is small, remove these bolts together with rubber washers.
Caution: Cover the exposed parts of the engine to prevent foreign particles from entering the engine when removing the front chain cover.
6. Set the piston of the 1st cylinder to the TDC position of the compression stroke.
By turning the crankshaft pulley clockwise, set the marks on the camshaft sprockets as shown in the figure.
Note:
The crankshaft pulley position indicator is missing.
The installation of the secondary timing chain is carried out according to the colors of the chain links, so there is no need for marking before removal, however, the mark on the fuel injection pump sprocket is difficult to see, so it is better to apply marks.
7. Remove the chain tensioner.
Shoot in the following sequence.
(1) Press the chain tensioner plunger and secure it with the pin.
(2) Loosen the mounting bolts with a hex key (special tool, 5 mm) and remove the chain tensioner.
8. Remove the chain guide at the bending point.
Loosen the mounting bolts using a hex key (special tool 6 mm, short) and remove the chain guide at the bending point.
9. Remove the chain guide at the tension point.
10. Remove the secondary timing chain.
You can remove the timing chain separately without removing the sprocket.
11. Fix the fuel injection pump sprocket.
(1) Insert the installation stopper (special tool) into a 6 mm diameter hole in the fuel injection pump sprocket.
(2) Using a TORX key (special tool) turn the pump shaft slowly and precisely position the sprocket, aligning the holes.
(3) Fix the fuel injection pump sprocket by pushing the installation stopper into the fuel injection pump body.
The installation stopper is inserted until the flange touches the fuel injection pump sprocket.
(4) Remove the TORX key.
12. Loosen the fuel injection pump sprocket mounting bolts (4 pcs.) using a hex key (special tool 6 mm, long).

There is no need to remove the sprocket washer.
13. Secure the fuel injection pump sprocket using the holder (special tool), so that she doesn't fall.
If the installation stop interferes with the installation of the sprocket holder, pull it out approximately 10 mm.
After pre-installing the sprocket holder, align the holes, insert the TORX key with extension into the 3 holes A and tighten the holder mounting bolts (3 pcs.) (for installation tool see item 14).
To install the sprocket holder, use Mb bolts approximately 15 mm long (excluding head).
Make sure that surfaces a and b of the holder contact the bottom surface of the small diameter sprocket.
Caution: Do not remove the sprocket holder until the injection pump is installed.
After removing the sprocket holder, remove the installation stopper from the fuel injection pump sprocket.
14. Using an extension cord (special tool, total length 43 mm) and a TORX key (Q6-E12, available for sale) remove the mounting bolts (3 pcs.) and remove the injection pump through the rear of the engine.
Even if you unscrew all the mounting bolts, the high-pressure fuel pump will still be held in place by the mounting pins.
Caution: Do not disassemble or adjust the injection pump.
Note: The high-pressure fuel pump cannot be repaired even at a service station.
15. Loosen the fuel injection pump mounting bolts.
Note: Sealing washers are not reusable.
