(6) 148-7211 Bridge Nut Socket

6. Hold the adjustment screw with the 148-7211 Bridge Nut Socket (6) in order to tighten thelocknut to 30 4 N (22 3 lb). You may use a torque computer in order to determine thetorque wrench dial reading for the different extensions. Refer to the Special Instruction,SEHS7150, "Snap On Torque Computer" for additional information.

Valve Lash Adjustment

Note: The 147-5482 Valve Lash Gauge Group cannot be installed on engines with the earlier8N-8788 Fuel Manifold .

Note: The valve bridges MUST be adjusted before making the valve lash adjustments.

1. Ensure that the number 1 piston is at the top center position. Refer to the Systems Operation,Testing And Adjusting, "Finding Top Center Position For No. 1 Piston" for additionalinformation.

2. The number 1 piston should be at the top center position of the correct stroke. Makeadjustments to the valves in accordance with the chart in the Systems Operation, Testing AndAdjusting, "Crankshaft Positions For Fuel Injector Lash And Valve Lash Setting".

Note: Tap each rocker arm on the top of the adjustment screw before making any adjustments.Use a soft hammer. Make sure that the lifter roller is seated against the base circle of thecamshaft.

Note: When you are using the 145-5191 Gauge Support to adjust the 3516 Diesel Engine that isinstalled in a 789 Off-Highway Truck, the knurled knob must be removed on the tool. Theknurled knob must be removed when you are measuring the valve lash on cylinder 5 andcylinder 12. The knurled knob must be removed due to the location of the oil lines from theturbocharger.

4. Move the rocker assembly up and down several times. The oil film is removed in order to get a

true zero reading on the dial indicator. Use both the 147-2060 Wrench (3) and the 147-2059Torque Wrench (4). Attach the socket wrench and the torque wrench to the nut of the rockerarm. Apply upward pressure to the front of the rocker assembly. Set the dial indicator to zero.The weight of the torque wrench (4) allows the valve lash to be read. Do not apply any pressureon the torque wrench.

5. Loosen the locknut. The locknut is located on the adjustment screw of the push rod. Turn theadjustment screw until the valve lash is set to specifications. Tighten the nut on the adjustmentscrew to a torque of 70 15 Nm (52 11 lb ft ). The 147-2059 Torque Wrench is preset to thetorque that is required. Check the adjustment again.
