The housing of the oil pump, the oil pump and balance shafts

Dismantling

The housing of the oil pump, the oil pump and balance shafts cm. To Fig. 2.85.

Remove the timing belt.

Remove the bolts from the oil pan.

Rubber hammer bring down the tray and remove both parts.

Remove maslozabornik and its lining.

Remove the gauge, oil pressure switch (Fig. 2.86).

Remove the oil filter bracket and gasket.

With the help of a special key (09213-33000), unscrew the cap of the oil pump in the front cover (Fig. 2.87).

Remove the plug on the left side of the cylinder block and insert a screwdriver into the hole plug diameter of 8 mm. Screwdriver should go to a depth of 60 mm (Fig. 2.88).

Remove the bolt of the oil pump driven gear and left balance shaft (Fig. 2.89).

Unscrew the front cover. Remove the cover and gasket (Fig. 2.90).

Remove both balance shaft.

Remove the front cover of the oil pump cover.

Remove the gear of the oil pump (Fig. 2.91).

Remove the screwdriver out of the hole plug on the left side of the cylinder.

Check the front cover

Check the condition of the oil passage cover. Clean if necessary.

Check the condition of the forward bearing of the balance shaft. If any failure of the bearing, replace the front cover.

Check for cracks or other damage to the cover.

If necessary, replace the front cover.

Checking the balance shafts

Check for wear or scoring necks balance shafts (Fig. 2.92).

If you have a bully necks, carefully check the condition of bearings.

If necessary, replace the bearings or the balancer shaft.

Checking the oil seal

Check the oil seal lip on the absence of deterioration. Replace oil seal if necessary.

Check the gauge-switch of pressure of oil

Use an ohmmeter to check for a closed circuit between the terminal and the housing of the sensor switch. If there is no continuity, replace the sensor switch (Fig. 2.93).

Insert a thin rod into the hole of the gauge-switch and push the diaphragm. If between the terminal and the housing of the sensor circuit-breaker remains closed, replace the gauge-switch (Fig. 2.94).

If between the terminal and the housing of the sensor-switch circuit is open when the diaphragm gauge-switch operates vacuum of 50 kPa, the sensor switch defective. If depression is not maintained, then the sensor diaphragm destroyed. Replace the sensor switch.

Check the oil pump

Install the oil pump gear to the front door. Check for smooth rotation of the gears and no significant gap in engagement.

Check for signs of wear ring end surfaces of the front cover and oil pump (the contact with gears).

Measure the gap between the pump casing and the tops of the teeth of gears (Fig. 2.95).

Nominal backlash:

Pinion ...... 0,16-0,21 mm

Driven gear ..... 0,18-0,21 mm

The maximum gap:

Pinion 0.25mm .....

Driven gear ..... 0.25 mm

Measure end clearance (Fig. 2.96).

Nominal backlash:

Pinion ..... 0,08-0,14 mm

Driven gear ...... 0.06-0.12 mm

The maximum gap:

Pinion 0.25mm .....

Driven gear ..... 0.25 mm

Replacing bearing balance shaft

With a special tool remove the cylinder from the front bearing right balance shaft (Fig. 2.97).

With a special tool remove the cylinder from the rear bearing of the right balance shaft (Fig. 2.98).

With a special tool remove the cylinder from the rear bearing of the left balance shaft. Tool fix on the front end of the unit (Fig. 2.99).

Using a special tool, set the cylinder block of the left rear bearing balance shaft.

Rear left balance shaft bearing has no oil supply hole.

Using a special tool, set the cylinder block rear bearing right balance shaft (Fig. 2.100).

Align the holes in the bearing oil supply and the block (Fig. 2.101).

Using a special tool, set the crankcase front bearing right balance shaft (Fig. 2.102).

Assembly

Lubricate the gear oil pump engine oil. Install the pinion into the housing by aligning the timing marks (Fig. 2.104).

With the help of a mandrel (09214-32000) set in the cover of the crankshaft front oil seal (Fig. 2.105).

Install the crankshaft mandrel (09214-32100). Lubricate the mandrel motor oil (Fig. 2.106).

Establish a new lining of the front cover. Install the front cover. Hand tighten the bolts.

Tighten regulated torque (Fig. 2.107).

Tightening torque of the front cover bolts: 20-27 Nm.

Insert a screwdriver into the hole plug on the left side of the unit. Check the depth of call screwdriver. If necessary, change the position of the balance shaft. Tighten the new bolt shaft.

Install new O-ring plug the oil pump.

Using a special wrench, tighten the plug pump regulated torque.

The tightening torque of the oil pump plug: 20-27 Nm.

Coat the oil pan flange-groove bead of sealant as shown in Figure 2.108.

Install the upper and lower trays, tighten the bolts regulated torque.

Tightening torque bolts sump: 10-12 Nm.

Coat the threads of the gauge-switch of pressure of oil sealant. Deep-head screw 24 mm sensor.

Sealant: Three Bond 1104 or equivalent.

Tightening torque gauge-switch of pressure of oil: 8-12 Nm.
