This Haynes repair and service manual, covers 1977-1984 Datsun 810 and Nissan Maxima Sedan and Station Wagon body styles with 2.3L engines coupled to a 4- or 5-speed manual or to an automatic transmission. Note: this manual does not cover diesel engines.

ENGINE | FINAL ASSEMBLY AND ADJUSTMENTS

1. Install the oil pump as described in Section 15.
2. Assemble the thermostat housing, thermo time switch, thermal transmitter and water temperature sensor.
3. Install the oil strainer to the oil pump intake tube (photo).
4. Locate a new gasket on the crankcase flange after applying gasket cement to both sides of it (photo).
5. Bolt on the oil pan, tightening the bolts evenly and in a diagonal sequence to the specified torque (photo).
6. Check the valve lash (clearance). To do this, turn the crankshaft until the number 1 piston is at TDC on it?s compression stroke. In this position the high points of the cam lobes will be furthest from the rocker arms. Check the clearances between the ends of the valve stems and the rocker arm tips by inserting the appropriate feeler blade; the blade should be a stiff sliding fit (photo).
7. To adjust the clearing, release the locknut and turn the pivot screw. The valve clearances cold are given in the Specifications.
8. As the firing order is 1-5-3-6-2-4, it will reduce the amount of crankshaft rotation required if the valve clearances are adjusted in accordance with the firing order. To obtain a better appreciation of the valve clearance it is recommended that the rocker arm springs are detached. Numbering from the front, the inlet valves are 2,3,5,8,10 and 11 and the exhaust valves 1, 4, 6, 7, 9 and 12.
9. When carrying out valve clearance adjustment with the engine in the car, the crankshaft can most easily be turned by engaging top gear, an jacking-up and turning a rear road wheel (manual transmission). On cars fitted with an automatic transmission a wrench will have to be applied to the crankshaft pulley bolt which makes the adjustment procedure somewhat more protracted. With either method the work will be facilitated if the sparkplugs are first removed.
10. Refit all the ancillary components by reversing the operations described in Section 9. Reference should be made to Chapter 5 for the method of centralizing the clutch driven plate, and to Section 15 for installation of the distributor.

REAR AXLE

AXLE SHAFT, BEARING AND OIL SEAL ? REMOVAL AND INSTALLATION (STATION WAGON)

1. Chock the front wheels, jack-up the rear of the vehicle and place on firmly based axle stands. Remove the rear wheel.
2. Refer to Chapter 9. Remove the brake drum, disconnect the pipe to the wheel cylinder and the parking brake linkage from the back plate.
3. Undo and remove the four nuts that secure the back plate to the axle casing. There are two holes in the axle shaft flange to allow for access.
4. The axle shaft assembly may now be withdrawn from the axle casing. If tight, it will be necessary to use a slide hammer or tire levers to ease the wheel bearing from the axle casing.
5. Remove the bearing collar by splitting with a chisel; a new one will be required on reassembly.
6. Should a new bearing be required this job should be left to the local Datsun garage. They are installed under a force of between 4 and 5 tons, and a press is necessary.
7. Reassembly and installation of the axle shaft assembly is the reverse sequence to removal. The following additional points should be noted:
1. Make sure the wheel bearing is well packed with grease.
2. Pack the lip of the oil seal with a little grease.
3. Top-up the rear axle oil lever.
4. Bleed the brake hydraulic system as described in Ch. 9.

PINION OIL SEAL | RENEWAL (STATION WAGON)

1. The procedure for installing a new pinion oil seal is basically similar to that described for the sedan model, which is described in Section4.
2. The pinion nut should be tightened to a torque of 94 lb./f (13.0 kg/f m), at which the bearing preload (force required to turn the pinion flange) should be 7.1 to 9.0 lb./f (3.2 to 4.1 kg/f). If this is not so, progressively tighten the pinion nut until the correct preload is obtained. If the torque applied to the pinion nut exceeds 130 lb./f (18.0 kg/f m), renew the pinion nut and repeat this process.
