TENSION ADJUSTMENT

Generator and air conditioner compressor beltAdjusting bolt on idler pulley

TENSION ADJUSTMENT SPECIFICATION

CAUTIONWhen belt is replace with a new one, adjust it to value for "New belt" to accommodate for insufficient adaptability with pulley grooves. When deflection or tension of belt being used exceeds "Used belt limit" adjust it to value for "Used belt". When checking belt deflection or tension immediately after installation, first adjust it to the specification value. Then, after turning the crankshaft two turns or more, readjust to the specified value to avoid variation in deflection between pulleys. When installing belt, make sure that it is correctly engaged with pulley groove. Keep oil and water away from belt. Do not twist or bend belt excessively.

  1. Remove engine undercover.
  2. Loosen idler pulley lock nut "A" and adjust by turning adjusting bolt "B". For specified belt tension, refer to «DRIVE BELTS»(ref-233644-S15739428032006052600000) .
  3. Tighten lock nut "A". Lock nut "A": 30.4 - 39.2 N.m (3.1 - 3.9 kg-m, 23-28 ft-lb)
  4. Tighten adjusting bolt "B". Adjusting bolt "B": 3.9 - 6.9 N.m (0.4 - 0.7 kg-m, 35-61 in-lb)

  1. Remove engine undercover.
  2. Loosen adjusting bolt "C".
  3. Loosen power steering oil pump bolt "D". NOTE: Bolt head "D" is at the engine rear side.
  4. Adjust by turning the adjusting bolt "E". For specified belt tension, refer to «DRIVE BELTS»(ref-233644-S15739428032006052600000) . NOTE: Adjusting bolt "E" is loosened with counterclockwise rotation.
  5. Tighten adjusting bolt "C". Adjusting bolt "C": 24.5 - 31.4 N.m (2.5 - 3.2 kg-m, 18 - 23 ft-lb)
  6. Tighten power steering oil pump bolt "D". Power steering oil pump bolt "D": 36.3 - 50.0 N.m (3.7 - 5.1 kg-m, 27 - 36 ft-lb)

WHEEL BALANCE ADJUSTMENT

Note. If a tire balance machine has an adhesion balance weight mode setting and drive-in weight mode setting, select and adjust in the drive-in weight mode suitable for the road wheels.

  1. Set the road wheel on the wheel balancer using the center hole as a guide. Start the tire balance machine.
  2. When the inner and outer unbalance values are shown on the wheel balancer indicator, multiply outer unbalance value by 1.6 to determine balance weight that should be used. Select the outer balance weight with a value closest to the calculated value, then install it at the designated outer position of, or at the designated angle position on the road wheel. Outer balance weight calculation: Indicated unbalance value x 1.6 = outer balance weight Calculation example: 23 g (0.81 oz) x 1.6 = 38.33 g (1.35 oz) = 40 g (1.41 oz) outer balance weight (closer to calculated balance weight value) NOTE: The selected balance weight value must be the closest balance weight available to the calculated balance weight value. Example: 37.4 = 35 g (1.23 oz) 37.5 = 40 g (1.41 oz) CAUTION: Do not install the inner balance weight before installing the outer balance weight. Before installing the balance weight, be sure to clean the mating surface of the road wheel. Install the balance weight in the position as shown. When installing the balance weight to the road wheels, set it into the grooved area on the inner wall of the road wheel as shown, so that the balance weight center is aligned with the wheel balancer indication position (angle). CAUTION: Always use genuine NISSAN adhesion balance weights. Balance weights are not reusable; always replace with new ones. Do not install more than three sheets of balance weight. If calculated balance weight value exceeds 50 g (1.76 oz), install two balance weight sheets in line with each other. CAUTION: Do not install one balance weight sheet on top of another.
  3. Start the wheel balancer.
  4. Install the drive-in balance weight on the inner side of the road wheel in the wheel balancer indication position (angle). CAUTION: Do not install more than two balance weights in one position (angle).
  5. Start the wheel balancer. Make sure that the inner and outer residual unbalance values are 10 g (0.35 oz) each or less. If either residual unbalance value exceeds 10 g (0.35 oz), repeat the installation procedures. Wheel balance (maximum allowable unbalance): WHEEL BALANCE REFERENCE CHART Maximum allowable unbalance Dynamic (at rim flange) 10 g (0.35 oz) (one side) Static 20 g (0.71 oz)

Scheme 7: Tire Rotation
Scheme 7: Tire Rotation
  1. After rotating the tires as shown, adjust the tire pressure to specification.
  2. Retighten the wheel nuts after the vehicle has been driven the first 1,000 km (600 miles). Also retighten the wheel nuts after a flat tire repair, or any type of service where the wheels have been removed and installed. Wheel nuts: 98 - 117 N.m (10 - 12 kg-m, 73 - 86 ft-lb)

Scheme 8: Checking Brake Fluid Level and Leaks
Scheme 8: Checking Brake Fluid Level and Leaks
  1. Check the brake fluid level in the reservoir tank. It should be between the "MAX" and "MIN" lines on the reservoir tank.
  2. If the brake fluid level is extremely low or below the "MIN" level, check the brake system for leaks.
  3. Release the parking brake lever and check that the brake warning lamp goes off. If not, check the brake system for leaks.
