Engine Mechanical: Adjustments Nissan Rogue II

Tension Adjustment

Belt tension is not manually adjustable. It is automatically adjusted by the drive belt auto-tensioner.

Scheme 4

1. Remove wheel and tire (RH) using a power tool.
2. Remove engine under cover. Refer to " «FLOOR UNDER COVER: REMOVAL AND INSTALLATION»(ref-616717-S18651389222014051900000) "
3. Remove fender protector side cover. Refer to " «FENDER PROTECTOR: EXPLODED VIEW»(ref-616717-S39205674252014051900000) ".
4. Securely hold the hexagonal part (A) of drive belt auto-tensioner (1) using suitable tool, and move in the direction of arrow --> (loosening direction of tensioner).
5. Insert a rod approximately 6 mm (0.24 in) in diameter through the rear of the drive belt auto-tensioner into retaining boss (B) to lock drive belt auto-tensioner pulley. WARNING: Avoid placing hand in a location where pinching may occur if the holding tool accidentally comes off. NOTE: Leave drive belt auto-tensioner pulley arm locked until drive belt is installed again.
6. Loosen drive belt from drive belt auto-tensioner and then remove it from the other pulleys.
7. Installation of remaining components is in the reverse order of removal.

ADJUSTMENT

Note. Perform adjustment by selecting the valve lifter with the correct head thickness.

Scheme 6

1. Remove camshaft. Refer to " «EXPLODED VIEW»(ref-616715-S36134938302014051900000) ".
2. Remove the valve lifters at the locations that are outside the standard.
3. Measure the center thickness of the removed valve lifters with a suitable tool (A).
4. Use the equation below to calculate valve lifter thickness for replacement. Valve lifter thickness calculation. t = t1 + (C1 - C2) t = Thickness of replacement valve lifter. t1 = Thickness of removed valve lifter. C1 = Measured valve clearance. C2 = Standard valve clearance. Thickness of a new valve lifter (B) can be identified by stamp marks (A) on the reverse side (inside the cylinder). Stamp mark 324H indicates a thickness of 3.24 mm (0.1276 in) Available thickness of valve lifter: 26 sizes with a range of 3.00 to 3.50 mm (0.1181 to 0.1378 in), in steps of 0.02 mm (0.0008 in), when assembled at the factory.
5. Install the selected valve lifter.
6. Install camshaft. Refer to " «EXPLODED VIEW»(ref-616715-S36134938302014051900000) ".
7. Install timing chain and related parts. Refer to " «EXPLODED VIEW»(ref-616715-S06805958952014051900000) ".
8. Manually rotate crankshaft pulley a few rotations.
9. Check that valve clearances for cold engine are within specifications by referring to the specified values. Valve clearance Refer to " «CAMSHAFT»(ref-616715-S28504132322014051900000) ".
10. Install all removed parts in the reverse order of removal.
11. Warm up the engine, and check for unusual noise and vibration.

Scheme 8

1. Warm up the engine to full operating temperature.
2. Release the fuel pressure. Refer to " «WORK PROCEDURE»(ref-616720-S42626896142014051900000) ".
3. Remove the ignition coil and spark plug from each cylinder. Refer to " «REMOVAL AND INSTALLATION»(ref-616715-S41796736592014051900000) " and " «REMOVAL AND INSTALLATION»(ref-616715-S21266772742014051900000) ".
4. Connect engine tachometer (not required in use of CONSULT).
5. Disconnect the fuel injector harness connector to avoid any residual fuel injection during the measurement.
6. Install the compression tester with the adapter into the spark plug hole. Use compression tester whose end (a) (rubber portion) is smaller than 20 mm (0.79 in) in diameter. Otherwise, it may be caught by cylinder head during removal.
7. With the accelerator pedal fully depressed, turn the ignition switch to the "START" position to crank over the engine. When the gauge pointer stabilizes, read the compression pressure and engine RPM. Perform these steps to check each cylinder. Unit: kPa (kg/cm 2 , psi)/rpm Standard Minimum Difference limit between cylinders 1410 (14.4, 204.5)/250 1220 (12.4, 176.9)/250 100 (1.0, 14)/250 CAUTION: Always use a fully charged battery to obtain specified engine cranking speed. If the engine speed is out of specified RPM range, check the battery. Check engine speed again with a fully charged battery. If compression pressure is below minimum value, check valve clearances and parts associated with combustion chamber (valve, valve seat, piston, piston ring, cylinder bore, cylinder head, cylinder head gasket). After the checking, measure compression pressure again. If some cylinders have low compression pressure, pour small amount of engine oil into the spark plug hole of the cylinder to re-check it for compression. If the added engine oil improves the compression, the piston rings may be worn or damaged. Check the piston rings and replace if necessary. If the compression pressure remains at low level despite the addition of engine oil, the valves may be malfunctioning. Check the valves for damage. Replace the valve or valve seat accordingly. If two adjacent cylinders have respectively low compression pressure and their compression remains low even after the addition of engine oil, the head gasket is leaking. In such a case, replace the cylinder head gasket.
8. Install spark plug, ignition coil and harness connectors. Refer to " «REMOVAL AND INSTALLATION»(ref-616715-S21266772742014051900000) ".
