Removing the cylinder head, checking the axial play of the balancing shafts
Using a 10mm socket wrench, in several passes, loosen and remove the ten cylinder head bolts in the sequence shown in Figure 13.
If the bolts are loosened in the wrong order, the cylinder head may be damaged or cracked in the cylinder head.
Remove ten washers.
Use a screwdriver to separate the head from the cylinder block.
Remove the cylinder head gasket.
Remove the oil cooler fitting.
Remove the VVT-i oil filter.
Use a dial indicator to measure the end play while moving the balance shafts back and forth (fig. 14).
Axial play of balance shafts:
- standard - 0.050-0.090 mm;
- maximum allowable - 0.090 mm.
Checking the radial play of the balance shafts
In several passes, sequentially, unscrew the eight fastening bolts and remove the cover of the balancing mechanism (Fig. 15).
Using a plastic calibrator, measure the clearances in the plain bearings for each journal (Fig. 16).
Apply some engine oil under the heads and on the threads of the mounting bolts.
Install the balance mechanism cover.
In several passes, sequentially, tighten the eight bolts securing the cover of the balancing mechanism with a tightening torque of 22 Nm (Fig. 17).
Mark the bolts with paint.
Tighten the bolts by 90° in the sequence shown in Figure 2.70.
Make sure the markings on the bolts are now at 90° from their original position.
Remove the balance mechanism cover. Measure the maximum width of the flattened gauge wire to determine the radial clearance.
Radial clearance:
- standard - 0.004-0.031 mm;
- maximum allowable - 0.031 mm.
If the clearance exceeds the limit, replace the balance shaft bearings.
If the clearance is within specification, reinstall the balance shaft bearings.
When replacing standard size liners, use liners of the same size group.
There are three standard earbud sizes.
Bearing bed diameter:
- marking "1" ..... 26.000–26.006 mm;
- marking "2" ..... 26.007–26.012 mm;
- marking "3" ..... 26.013–26.018 mm.
The diameter of the bearing journal is 22.985–23.000 mm
Liner wall thickness (in the central part):
- marking "1" ..... 1.486–1.489 mm;
- marking "2" ..... 1.489–1.492 mm;
- marking "3" ..... 1.492–1.495 mm.
Replacing the crankshaft rear oil seal
Cut off the lip of the gland with a knife. Using a cloth-wrapped screwdriver, pry out the oil seal (fig. 19).
Using sandpaper, remove the remnants of the oil seal from the edge of the rear oil seal holder.
Apply grease to the surface of the new oil seal.
Using a drift and a hammer, press in the new oil seal so that its surface does not protrude beyond the edge of the edge of the rear oil seal holder.
In several passes, sequentially, unscrew the eleven crankcase mounting bolts (Fig. 20).
Checking the timing chain and the sprocket of the shafts
Measure the length of fifteen links of the chain under tension with a vernier caliper.
If the chain length is fifteen links longer than the maximum, replace the chain.
Make three or more measurements on arbitrary sections of the circuit.
Wrap the chain around the sprocket.
Measure the diameter of the sprocket over the rollers with a vernier caliper as shown in Figure 21.
Minimum sprocket diameter:
- - camshaft - 97.3 mm;
- - crankshaft - 51.6 mm.
If the diameter is not as specified, replace sprockets with chain.
Check the tensioner shoe and timing chain guide for wear.
Maximum wear should not exceed 1 mm.
Checking the operation of the timing chain tensioner divisions
Make sure the plunger moves freely when the ratchet is raised.
Release the ratchet and make sure the plunger is locked (fig. 22).
Checking camshaft runout
Install the camshaft on two prisms.
Place the sensitive head of the indicator on the neck.
Turn the camshaft by hand to one side and measure the runout with a dial gauge (maximum dial reading) (fig. 23).
The maximum runout tolerance is 0.03 mm.
Checking the camshaft lobe height
Measure the height of the camshaft lobe (fig. 24).
Standard cam contour height is 46.495–46.595 mm.
The minimum height of the cam contour is 46.385 mm.
Camshaft journal clearance (outer diameter of the camshaft journal)
Measure the outer diameter of the camshaft journal (fig. 25).
Standard camshaft bracket inner diameter:
- No. 1.....35.971–35.985 mm;
- No. 2,3,4,5.....22.959–22.975 mm.
Installing wt sprocket (intake camshaft)
Hold the sprocket in such a position that the groove in it is slightly to the left of the camshaft locating pin (shaft side).
Install the sprocket onto the camshaft.
Press lightly on the star and rotate it counterclockwise.
Make sure there is no visible gap between the sprocket and the end of the camshaft.
Hold the shaft with a spanner and tighten the mounting bolt to 54 Nm.
Make sure the WT drive moves clockwise and locks with the locking pin in the correct position (fig. 26).
