Unit: mm (in.)Loosen the cylinder head bolts slightly then retighten them to the specified torques.
Adjusting valve clearance
Unit: N*m {kgf*m} (lbf-ft)(1) Inspecting Valve Clearances(a) Inspect each cylinder's valve clearances with the piston at the top-dead-center (TDC) position of its compression stroke. Follow the firing order, bringing the pistons to the TDC positions of their respective compression strokes by turning the crankshaft in the forward direction in increments of 180°.(2) Confirming Compression-Stroke TDC Position(a) Bring piston No. 1 to the TDC position of its compression stroke. To do this, align the TDC mark on the crankshaft pulley with the mark on the gear case.(b) To confirm the compression-stroke TDC position, turn the crankshaft by approximately 20° in the forward and reverse directions and check for rocker-arm movement. When there is no rocker-arm movement, the piston is at the compression-stroke TDC position.(c) If rocker-arm movement occurs, the piston is at the TDC position of its intake or exhaust stroke. Give the crankshaft one more 180° turn to bring the piston to the TDC position of its compression stroke.
Retightening sequence for cylinder head bolts (d) Start bringing the piston to the TDC position with cylinder No. 1 for inspection/adjustment of the valve clearance. Then, proceed to the other cylinders' pistons in accordance with the firing order. After cylinder No. 1, bring the piston in the next cylinder to its compression-stroke TDC position by turning the crankshaft in the forward direction (clockwise as seen from the timing gear case) by 180°.
Before starting the engine, place the timing gears in their original positions.
Timing marks(3) Adjusting Valve Clearances(a) Loosen the rocker arm nut, then adjust the clearance to the standard value using the adjusting screw and a thickness gauge (1).(b) Hold the adjusting screw in position while tightening the nut.
When adjusting the valve clearances following disassembly and reassembly, turn the crankshaft two or three times then check again that the clearances are within specification.
Adjusting valve clearance1.2 Bleeding Air From Fuel SystemAir should be bled first from the fuel filter and then from the injection pump, i.e., starting at the position closer to the fuel tank.(1) With the system with an electromagnetic-plunger-type fuel pump, turn the key to the ON position to force fuel to flow. Then, loosen the air vent screw (1), allow air in the filter to be expelled, and retighten the screw.(2) Loosen air vent screws (2) and (3) on the injection pump in that sequence to bleed air from the fuel pipe and injection pump.(3) When air-bleeding from screws (2) and (3) is complete, retighten each screw.(4) Air in the injection pipes and nozzles will be expelled automatically when the engine is cranked.
Bleeding air from fuel system1.3 Inspecting and Adjusting Injection Timing(1) Preparation for Inspection(a) Close the cock on the fuel filter.(b) Remove the No. 1 injection pipe.(c) Remove the No. 1 delivery valve holder, delivery valve, and spring. Then, refit only the delivery valve holder.(d) Connect the injection pipe on the pump side only to ensure that you can see when fuel stops flowing out.(e) Hold the speed control lever in the low-speed position.
Removing delivery valve and spring(2) Inspection(a) Open the cock on the fuel filter. If the system has an electromagnetic pump, turn the key to the ON position. Fuel will flow out of the injection pipe. Make ready a container to catch it. If the system has an electromagnetic pump, caution is required since fuel will emerge with great force.(b) Slowly turn the crankshaft clockwise. The injection timing is reached when fuel stops flowing out. When fuel has stopped flowing out, turn the crankshaft slightly in the reverse direction such that fuel flows out. Then, slowly turn the crankshaft clockwise again to more accurately verify the point at which stops flowing out.
Fuel flow
End of fuel flow(c) If the IT mark on the crankshaft pulley and the mark on the gear case are aligned when fuel stops flowing out, the injection timing is normal.
Timing marks(3) Adjustment(a) If the injection timing is out of specification, make adjustments by increasing or decreasing the thickness of the injection pump's mounting shim. A change of 0.1 mm in the shim thickness yields a change of approximately 1° in the injection timing.(b) Increasing the shim thickness retards the injection timing, and decreasing the shim thickness advances it. Shims are available in thicknesses of 0.2 mm (0.008 in.), 0.3 mm (0.012 in.), 0.4 mm (0.016 in.), and 0.8 mm (0.031 in.). The thicknesses are not indicated on the shims, so any shim should be measured with a vernier caliper before being used.
Before using any shim, apply sealant to both sides to prevent oil leakage.
(c) After making adjustments, check that the injection timing is correct.(d) Close the cock on the fuel filter, then fit the delivery valve spring and injection pipe in their original positions.

Adjusting injection timing1.4 Adjusting Idle Speed(1) Preparation for Adjustment(a) Warm up the engine until the coolant reaches a temperature of 60°C (140°F) or higher.(b) Make sure the valve clearances, injection timing, and injectors are normal.(2) Adjusting Low-Idle SpeedLoosen the lock nut on the idling set bolt, turn the bolt to achieve the specified low-idle speed (1,000 25 min-1), then tighten the lock nut to hold the bolt in that position.(3) Adjusting No-Load Maximum SpeedLoosen the lock nut on the high-speed set bolt, turn the bolt to achieve the specified no-load maximum speed (2870+30-10 min-1), then tighten the lock nut to hold the bolt in that position.
Adjusting idle speed1.5 Adjusting Fan Belt Tension(1) Press the fan belt with the specified force mid-way between the alternator pulley and crankshaft pulley, and observe the extent of deflection. (2) If the extent of deflection is out of specification, loosen the adjusting bolt and adjust the fan belt tension by moving the alternator. Retighten the adjusting bolt securely.
