VALVE GP-RELIEF 1090394 - Caterpillar

Adjust the speed on the calibration bench to the "LOAD STOP ADJ" rpm that is specified in the TMI. Adjust load stop adjustment screw (4) to the output dimension that is specified in the TMI.
Tighten the locknut for load stop adjustment screw (4) and check the output dimension again.
Increase the speed on the calibration bench by at least 100 rpm. Reduce the speed on the calibration bench back to the "LOAD STOP ADJ" rpm that is specified in the TMI. Check the output dimension again.
If the dimension is not within the "RECHECK TOL" that is specified in the TMI, repeat Step 9.
Adjust the speed on the calibration bench to the "FUNC CHECK #1" rpm that is specified in the TMI. The output dimension must be a maximum of 0.0 mm (0.00 inch).If the output dimension is more than 0.0 mm (0.00 inch), the bearing block assembly must be repositioned. Move the bearing block assembly toward the riser shaft approximately 0.5 mm (0.02 inch). Refer to the Disassembly and Assembly, "Governor (Type) - Disassemble" and Disassembly and Assembly, "Governor (Type) - Assemble" procedures in this manual. Return to Step 9 after installation.

Adjust the speed on the calibration bench to the "THROT STOP ADJ" rpm that is specified in the TMI. Adjust throttle stop adjustment screw (2) in order to obtain the output dimension for the "THROT STOP ADJ". Tighten the locknut for throttle stop adjustment screw (2) and check the output dimension again.If the output dimension for the "THROT STOP ADJ" cannot be obtained due to a low output dimension, it will be necessary to move the bearing block assembly away from the riser shaft approximately 0.5 mm (0.02 inch). This will increase the adjustments that are capable for the output dimension. Refer to the Disassembly and Assembly, "Governor (Type) - Disassemble" and Disassembly and Assembly, "Governor (Type) - Assemble" procedures in this manual. Return to Step 9 after installation of the bearing block assembly.Note: After adjustment, at least 2.0 mm (0.08 inch) of the throttle stop screw should extend past the housing surface. This will enable the high idle to be set with the governor on the engine.
Increase the speed on the calibration bench by a minimum of 100 rpm. Then reduce the speed back to the original "THROT STOP ADJ" rpm. Check the output dimension for the "THROT STOP ADJ".If the output dimension is not within the specification that is specified in the TMI, repeat Step 14.
Adjust the speed on the calibration bench to the "FUNC CHECK #2" rpm that is specified in the TMI. The output dimension must be within specifications. If the output dimension is not within specifications, repeat Steps 10 through 15.
Adjust the speed on the calibration bench to the "FUNC CHECK #3" rpm that is specified in the TMI. The output dimension must be within specifications. If the output dimension is not within specifications, inspect the torque cam for wear or damage. Make
