Removing
1. Remove the oil pump.
ENGINE TD6, REPAIR WORKS, Oil pump.
Disassembly
1. Turn away 10 bolts of fastening of the bottom plate of the block of cylinders and remove a plate.
2. Using tool LRT-12-212 mounted on the crankshaft pulley, rotate the crankshaft to gain access to the connecting rod bolts.
3. Mark connecting rods and connecting rod caps by cylinder number.
4. Loosen and remove the connecting rod bolts, save them for now.
CAUTION: The connecting rod caps are mounted on pins. Avoid side impacts on covers.
5. Remove connecting rod caps, remove and discard connecting rod bearings.
6. Rotate the crankshaft to allow the connecting rod to move away from the journal.
ATTENTION: The upper connecting rod bearings are run-in coated and are marked with the letter "S" or next to icons "xxx" on its back side.
7. Remove and dispose of the upper connecting rod bearings, making sure that there is a mark "S" on their backside.
8. Do the same with the rest of the connecting rod bearings. Lay out the connecting rod caps in the order they were on the engine.
Examination
1. Wipe the crankpins, new liners, beds of the upper and lower liners.
2. Measure the diameter of each crankpin in four directions at 90°intervals. Record the measurement results.
3. Wipe the connecting rod bolts and lubricate them with engine oil.
4. Turn the crankshaft so that the connecting rod journals of the first and sixth cylinders are in N.M.T.
5. Install new eartips marked in BLUE and with the letter "S", into the connecting rods of the first and sixth cylinders.
6. Install the new bearings marked in RED into the connecting rod caps of the first and sixth cylinders.
7. Put both connecting rods on the crankpins.
8. Place on the connecting rod journals of the first and sixth cylinders, in the axial direction, the strips of the deformable caliber.
9. Aligning the marks, install the connecting rod caps in their places.
10. Screw in the old connecting rod bolts and tighten them:
- Stage 1 - 5 Nm.
- Stage 2 - 25 Nm.
- Step 3 - Using an angle torque wrench, tighten the bolts 70°.
11. Remove the connecting rod bolts and remove the connecting rod caps.
12. Using a special ruler, measure the width of the deformable calibers and determine the clearance in the connecting rod bearings:
13. If the used connecting rod bearings cannot provide the required clearance, then the connecting rod journals must be ground to the next repair size and the appropriate repair bearings must be used.
14. Leave the approved liners in their places, in the connecting rods and roofs of the first and sixth cylinders.
15. With a rag moistened with engine oil, wipe off all remnants of the deformable caliber from the surface of the connecting rod journals.
16. Do the operations described above on the remaining connecting rod journals.
17. After checking the clearances in the connecting rod bearings is completed, dispose of the used connecting rod bolts.
Assembly
1. Lubricate the connecting rod journals and approved connecting rod bearings with clean engine oil.
2. Install the bearings of your choice to the connecting rods and to the connecting rod caps, making sure to use the bearings marked with the letter "S".
3. Lower the connecting rods onto the crankpins, paying attention to the correct position of the liners.
4. Aligning the marks, install the connecting rod caps in their places.
5. Lubricate new connecting rod bolts with clean engine oil.
6. Screw in new connecting rod bolts and tighten them:
- Stage 1 - 5 Nm.
- Stage 2 - 25 Nm.
- Step 3 - Using an angle torque wrench, tighten the bolts 70°.
7. Wipe down the bottom plate and counter mating surface.
8. Replace the bottom plate, install the bolts and tighten them evenly. Tightening torque 22 Nm.
Installation
1. Install the oil pump.
