Valve Lash Setting
The valve lash setting is for a cold engine.Valve lash setting Inlet valve ... 0.2 mm (0.0078 inch) Exhaust valve ... 0.2 mm (0.0078 inch)Valve Lash Adjustment
If the valve lash requires adjustment several times in a short period of time, excessive wear exists in a different part of the engine. Repair the problem in order to prevent more damage to the engine.Not enough valve lash can be the cause of rapid wear of the camshaft and valve lifters. Not enough valve lash can indicate that the seats for the valves are worn.Valves become worn due to the following causes:
Incorrect operation of fuel injection nozzles
Excessive dirt and oil are present on the filters for the inlet air.
Incorrect fuel settings on the fuel injection pump.
The load capacity of the engine is frequently exceeded.Too much valve lash can cause broken valve stems, springs, and spring retainers. Too much valve lash can be an indication of the following problems:
Worn camshaft and valve lifters
Worn rocker arms
Bent pushrods
Broken socket on the upper end of a pushrod
Loose adjustment screw for the valve lashIf the camshaft and valve lifters show rapid wear, look for fuel in the lubrication oil or dirty lubrication oil as a possible cause.The valve lash is measured between the top of the valve stem and the rocker arm lever.Note: No. 1 cylinder is at the front of the engine.Remove the valve mechanism cover and perform the following procedures in order to adjust the valve lash:Note: When these procedures are performed, the front housing must be installed.

Accidental engine starting can cause injury or death to personnel.To prevent accidental engine starting, turn the ignition switch to the OFF position, place a do not operate tag at the ignition switch location and disconnect and tape the electrical connection to the stop solenoid that is located on the fuel injection pump.
Valve Lash Adjustment for Three Cylinder Engines
Rotate the crankshaft in a clockwise direction that is viewed from the front of the engine. When the inlet valve of the No. 1 cylinder has opened and the exhaust valve of the No. 1 cylinder has not completely closed measure the valve lash of the inlet valve of No. 2 cylinder and the exhaust valve of No. 3 cylinder. If necessary, make adjustment.
Loosen the valve adjustment screw locknut that is on adjustment screw (1) .
Place the appropriate feeler gauge (2) between the rocker arm and the valve. Turn adjustment screw (1) while the valve adjustment screw locknut is being held from turning. Adjust the valve lash until the correct specification is achieved.
After each adjustment, tighten the valve adjustment screw locknut while adjustment screw (1) is being held from turning.
Rotate the crankshaft in a clockwise direction that is viewed from the front of the engine. When the inlet valve of the No. 2 cylinder has opened and the exhaust valve of the No. 2 cylinder has not completely closed measure the valve lash of the inlet valve for No. 3 cylinder and the exhaust valve for No. 1 cylinder.If adjustment is necessary, refer to Steps 1.a, 1.b, and 1.c above.
Rotate the crankshaft in a clockwise direction that is viewed from the front of the engine. When the inlet valve of the No. 3 cylinder has opened and the exhaust valve of the No. 3 cylinder has not completely closed measure the valve lash of the inlet valve for No. 1 cylinder and the exhaust valve for No. 2 cylinder.If adjustment is necessary, refer to Steps 2, 1.b, and 1.c above.Valve Lash Adjustment for Four Cylinder Engines
Rotate the crankshaft in a clockwise direction that is viewed from the front of the engine. When the inlet valve of the No. 4 cylinder has opened and the exhaust valve of the No. 4 cylinder has not completely closed measure the valve lash of the inlet valve and the exhaust valve of the No. 1 cylinder. If necessary, make adjustment.
Loosen the valve adjustment screw locknut that is on adjustment screw (1) .
Place the appropriate feeler gauge (2) between the rocker arm and the valve. Turn adjustment screw (1) while the valve adjustment screw locknut is being held from turning. Adjust the valve lash until the correct specification is achieved.
After each adjustment, tighten the valve adjustment screw locknut while adjustment screw (1) is being held from turning.
