Diesel engine unsealing In order to prevent the diesel engine from rusting, when the product leaves the factory, both inside and outside is sealed with oil. Therefore, after the new unit is installed and meets the installation requirements, it must be unsealed before it can start. Otherwise, it will cause the danger. So it should be taken seriously. The steps to remove the oil seal are as follows: 1) Heating the diesel above 45 ℃ to 56 ℃ for cleaning and removing the external anti-rust oil. 2) Heating water aover 90 ℃ , then continuously pouring water through the water jacket outlet, flowing out from the plug assy Irain (or water pump inlet) on the side of the cylinder body, continuously for 2--3 hours, and rolling the crankshaft  discontinuously to make the anti-proof oil of piston top, cylinder liner surface and elsewhere dissolves and flows out. 3) Clean the oil sump with clean diesel oil and replace it with new oil. Cooling and fuel system, ...

This post is mainly written to introduce how to adjust crosshead, injector and valves of Cummins NT diesel engines correctly. Pay attention to reading and you will learn more. Crosshead Adjustment Note: Crosshead adjustment should always be made before attempting to adjust the valves. 1. Loosen the locknut on the crosshead adjusting screw. Turn the adjusting screw out at least one turn. 2. Hold the crosshead down against its mating valve stem. Turn the adjusting screw back in until it touches the valve stem. Hold the adjusting screw in this position and tighten the locknut. 3. Tighten the adjusting screw locknut to 25 to 30 ft-lb [34 to 41 N*m] torque. Note: When ST-669 Torque Wrench Adapter is used, tighten the locknut to 22 to 26 ft-lb [30 to 35 N*m] torque. 4. Check the clearance between the crosshead and valve spring retainer 1 and 2. Fig. 2-19 with a wire gauge. Tighten must be a minimum of 0.025 inch [0.64 mm] clearance. Valve Adjustment The ...

Radiator is very important for a diesel generator set. It is used for heat dissipation. In most cases, it will affect the normal operation of the genset without a proper maintenance or incorrect use of radiator. 1. Usually, corrosion is the main cause for radiator failure. In the process of using, the air in the water will accelerate the corrosion process. Therefore, doing a regular maintenance for the pipe joint is quite necessary to avoid leaking. Meanwhile, do not forget to regularly add water to drain air from the top of the radiator. Attention: Radiators should not be partially injected with water, which will speed up corrosion. For non-working generating sets, water should be completely removed or fully filled. If possible, please use distilled water or natural soft water and add appropriate amount of antirust agent. 2. Coolant of the working radiator is usually very hot and with pressure, you are not allowed to tidy the radiator or dismantle the pipes before cool...

1. Each component of the gas generator set must be maintained in accordance with the method and time specified in the manual. No maintenance exceed the time limit or improper maintenance method will lead to the performance of the unit decline, and even cause serious accidents. 2. When carrying out  maintenance on the generator set , care should be taken to prevent the cotton yarn from being caught in the rotating parts, and the protective net is no exception. 3. Gas pipelines, valves, flanges, joints, etc., should be inspected regularly. There should be no gas leakage or damage. There should be no accumulation around the valve that interferes with the operation of the valve. The valve should be opened and closed regularly for maintenance. If the valve is unable to open or close, it should be repaired or replaced in time. 4. The hose on the gas pipeline should be replaced regularly. It is strictly prohibited to use expired and aging rubber hose. In particular,...
