Engine Valve Lash - Inspect/Adjust SMCS - 1102-025

Be sure the engine cannot be started while this maintenance is being performed. To prevent possible injury, do not use the starting motor to turn the flywheel. Hot engine components can cause burns. Allow additional time for the engine to cool before measuring/adjusting engine valve lash clearance. The valve lash is measured between the top of the cap of the valve stem and the rocker arm. The valve lash is measured with a feeler gauge. Valve Lash Setting with Stopped Engine (Cold) Inlet ... 0.25 mm (0.010 inch) Exhaust ... 0.40 mm (0.016 inch)

Adjustment of the Height of the Valve Bridge

Then, turn the adjustment screw (4) in a clockwise direction. Slide the feeler gauge between the rocker arm and the valve bridge. Continue turning the adjustment screw until a slight drag is felt on the feeler gauge. Remove the feeler gauge. 10. Tighten the adjustment locknut (3) to a torque of 4 ± 1 N·m (35 ± 9 lb in). Do not allow the adjustment screw (4) to turn while you are tightening the adjustment locknut (2) . Recheck the valve lash after tightening the adjustment locknut (3) . Adjusting the valve lash several times in a short period indicates wear in a different part of the engine. Find the problem and make any necessary repairs in order to prevent more damage to the engine. Rapid wear of the camshaft and tappets can occur if insufficient valve lash is not corrected. Insufficient valve lash can also be an indication of faulty valve seats. The following items are reasons for faulty seats of the valves: faulty fuel injection nozzles, restrictions to the air inlet, dirty air filters, incorrect fuel setting and overloading the engine. Broken valve stems, broken pushrods, or broken spring retainers can be caused by insufficient valve lash that is not corrected. A fast increase in valve lash can be an indication of any of the following items: z

Worn camshaft and tappets

z

Worn rocker arms

z

Bent pushrods

z

Loose adjustment screws for valve lash

z

Broken socket on the upper end of pushrod

Fuel in the lubrication oil may be a possible cause of rapid wear of the camshaft and the tappets. Dirty lubrication oil may also be a possible cause of rapid wear of the camshaft and tappets.

NOTICE Before operation, the pump must be lubricated with clean engine oil and the pump must turn freely by hand or damage to parts can be the result.

Note: The minimum acceptable oil pressure at low idle is 98 kPa (14 psi). Heat the oil pump gear (3) to 180 to 220 °C (356 to 428 °F) and support the end of the drive gear shaft in order to install the oil pump gear. Press the oil pump gear until the oil pump gear is flush with the end of the shaft.

NOTICE Do not use a torch to heat the gear. A torch can unevenly heat the gear causing warpage. The hardness of the gear may also be changed with the use of a torch.

The backlash between the oil pump gear (3) and the idler gear (4) is the following. ... 0.100 to 0.190 mm (0.0039 to 0.0075 inch) Note: Replace the gears if the backlash exceeds 0.35 mm (0.014 inch).

Procedure to measure the bore of main bearing journal 1. Put the main bearing caps in position in the cylinder block. Apply clean engine oil on the main bearing bolts. Install the main bearing bolts and tighten the main bearing bolts to a torque of 137 ± 5 N·m (100 ± 4 lb ft). 2. Measure the main bearing bores with a dial indicator. Subtract the diameter of the crankshaft journal from the inside diameter of the main bearing in order to determine the bearing clearance on the main journal. Clearance between the crankshaft journal and the main bearing is 0.050 to 0.118 mm (0.0020 to 0.0047 inch). Note: Replace the bearings or refinish the crankshaft to the next undersize bearing if the main bearing clearance exceeds 0.20 mm (0.008 inch). Note: The allowable tolerance for main bearing journals that are out of round is 0.010 mm (0.0004 inch). The maximum repair limit is 0.030 mm (0.0012 inch). If the repair limit is exceeded, regrind the bearing journals to the specified dimension.

Procedure to measure the bore of main bearing journal 1. Put the main bearing caps in position in the cylinder block. Apply clean engine oil on the main bearing bolts. Install the main bearing bolts and tighten the main bearing bolts to a torque of 137 ± 5 N·m (100 ± 4 lb ft). 2. Measure the main bearing bores with a dial indicator. Subtract the diameter of the crankshaft journal from the inside diameter of the main bearing in order to determine the bearing clearance on the main journal. Clearance between the crankshaft journal and the main bearing is 0.050 to 0.118 mm (0.0020 to 0.0047 inch). Note: Replace the bearings or refinish the crankshaft to the next undersize bearing if the main bearing clearance exceeds 0.20 mm (0.008 inch). Note: The allowable tolerance for main bearing journals that are out of round is 0.010 mm (0.0004 inch). The maximum repair limit is 0.030 mm (0.0012 inch). If the repair limit is exceeded, regrind the bearing journals to the specified dimension.

Piston Height - Inspect SMCS - 1214-040 If the height of the piston above the cylinder block is not within the tolerance that is given in the Specifications Module, "Piston and Rings", the piston and the bearing for the piston pin must be replaced. If any of the following components are replaced or remachined, the piston height above the cylinder block must be measured: z

Crankshaft

z

Cylinder head

z

Connecting rod

z

Bearing for the piston pin

z

Piston

The correct piston height must be maintained in order to ensure that the engine conforms to the standards for emissions. Note: The top of the piston should not be machined. If the original piston is installed, be sure that the original piston is assembled to the correct connecting rod and installed in the original cylinder.

1U-5470

Engine Pressure Group

1

An oil pressure gauge that has a defect can indicate low oil pressure. The 1U-5470 Engine Pressure Group can be used to check engine oil pressure.

Illustration 1 1U-5470 Engine Pressure Group

g00296486

The 1U-5470 Engine Pressure Group has a gauge that measures the oil pressure in the engine. Refer to Special Instruction, SEHS8907 for more information on using the 1U-5470 Engine Pressure Group. The information is included in the tool group. 1. Ensure that the engine is filled to the correct oil level. 2. Connect the 1U-5470 Engine Pressure Group to the sender for the engine oil or the sensor for the engine oil. 3. Operate the engine. Allow the engine to obtain normal operating temperature. 4. Keep the oil temperature constant with the engine at the rated rpm. Read the pressure gauge. 5. Refer to Table 2 in order to determine if the engine oil pressure is in tolerance. Table 2 Oil Pressure (1) Oil Pressure at 1500 rpm Oil Pressure at Idle (2)

145 kPa (21 psi) 48 kPa (7 psi)

(1)

The oil temperature must be 60° to 70°C (140° to 158°F).

(2)

Idle rpm is 900 ± 20 rpm.

Find the cause of the problem and correct the problem if the results of the test do not fall within the pressure range in Table 2. Engine failure or a reduction in engine life can be the result if engine operation is continued with oil pressure outside this range. Note: A record of engine oil pressure at regular intervals can be used as an indication of possible problems of the engine. A record of engine oil pressure at regular intervals can also be used as an indication of possible damage to the engine. The engine should be inspected and the problem should be corrected if there is a sudden increase or a sudden decrease of 70 kPa (10 psi) in oil pressure.
