OIL NON-RETURN VALVE Preceding Work : Removal of timing gear case cover
1 Oil Non-Return Valve
Functions The non-return valve prevents the oil in the chain tensioner from drying up. In other words, it stops oil-returning in order to
prevent the oil in the chain tensioner from getting dry. As aresult, the chain tensioner can be activated with oil in itself.
Replacement Procedure
1. Remove the non-return valve using a pliers.
2. Insert new non-return valve with hand.

OIL DIPSTICK GUIDE TUBE
1 Oil Dipstick Level Gauge
2 Oil Dipstick Guide Tube
3 O-ring
Removal & Installation Procedure
1. Pull out the oil dipstick level gauge (1).
2. Unscrew the bolt (4) and remove the oil dipstick guide tube (2).Installation Notice 4 Bolt (M6 X 16, 1 piece)
........................... 9-11 Nm
5 Clamp
Tightening Torque 9 - 11 Nm
It is very hard to remove the oil dipstick guide tube without
special tool. If it is not necessary, do not remove the guide tube.
3. Installation should follow the removal procedure in the reverse order.
4. Check for leaks by starting the engine.

16. Remove the power steering pump lines.Notice Completely drain the fluid.
17. Disconnect the fuel feed line with prefilter from the feed pump on injection pump.
18. Vehicle with automatic transmission. Remove the hydraulic lines (19, 20) from oil cooler (2).
19. Disconnect the engine harness.
20. Disconnect the preheating time relay cable.

Assembly ProcedureNotice In case the prechambers are reused, inspect the
prechambers thoroughly, if the ball pin by heat and fire is broken, it can not be used.
1. Clean the sealing surface of the prechamber.
2. Insert the prechamber into the cylinder head at the same time aligning the cam on the collar of the prechambers with the slots in the cylinder head. Notice If the spacer rings are fitted to the prechambers, the spacer rings should be replaced with rings of the same thickness.
Thickness of Spacer Ring 0.3, 0.6, 1.0 mm
3. Coat the threaded ring with oil and assemble the ring by using the serration wrench.
Tightening Torque 130 Nm

1B3-40 OM600 ENGINE MECHANICAL Disassembly Procedure
1. Completely drain the coolant from the radiator and cylinderblock.
2. Remove the cooling fan shroud.
3. Hold the fan with counter holder and remove the bolt and then remove the cooling fan. Notice Keep the fan in vertical position.
Counter Holder 603 589 00 40 00
5. Remove the nut.
6. Remove the nut on the tensioning lever and insert therod(F12 ´ 180mm). By pushing the rod to the arrow direction,
pull back the bolt.
7. Push the tensioning lever to the opposite direction to release the spring tension and remove the poly V-belt.
4. Remove the bracket oil dipstick tube.
