Genuine Common Rail Diesel Fuel Injection Pump VE6 /10F1900RND265 Engine Parts for TOYOTA HZJ75-HZJ79 1HZ

As the key “blood supply organ” of a diesel engine, the normal operation of a diesel fuel pump is directly related to the equipment's performance and life expectancy, and it is vital to follow the guidelines for proper use.

Fuel quality control is the cornerstone. Be sure to use clean, compliant diesel fuel, impurities and moisture is a big no-no. Tiny gravel will be like a hidden killer, scraping the pump precision plunger, valve seat, destroying the sealing; moisture in the low-temperature icing, easy to clog the oil pipe, high temperature can also trigger the impact of the explosion of the boiling pump body, so that the metal parts of the sudden cold and sudden heat fatigue cracks. Regular inspection and replacement of the fuel filter is indispensable, it is the first line of defense to block the intrusion of impurities, dirty and clogged in a timely manner, in order to ensure that the fuel is smooth and pure into the pump.

Installation links are carefully crafted. The location should be far away from high-temperature heat sources, such as the engine exhaust pipe near the hot area, will make the pump body uneven heat, oil viscosity, exacerbating the wear and tear of parts. Installation angle should be precise, strictly follow the instructions, deviation is easy to cause fuel precipitation accumulation, interference with the pumping efficiency, and even to the cavitation phenomenon, bubble rupture impact damage to the impeller and other components. The connecting pipeline must be sealed tight, small leaks not only waste of fuel, pollution of the environment, but also let the air to take advantage of the situation, destroying the vacuum in the pump, affecting the suction strength and pressure stability.

Routine maintenance at regular intervals. Before and after operation, visually check for leakage, pay attention to the temperature of the pump body whether it is abnormally hot, listen to the regularity of the running sound, abnormal noises may indicate bearing wear, loose parts. Regularly disassemble and clean key parts, such as plunger coupling, gently wipe with special cleaner to remove carbon and oil, to ensure smooth sliding and good sealing; replace the oil in the pump according to the mileage or working hours, and make sure there are no impurities mixed in the new oil before injecting it, and good lubrication is the secret to reduce friction and prolong the service life.

Keep the operation specification in mind. Before starting the equipment, the first manual pre-pumping several times, to exclude the pipeline air, to prevent the “air lock” obstruction of the initial flow of fuel; stop don't be in a hurry, it is advisable to idle for a few minutes, to help the pump and the engine to cool down evenly, to avoid sudden stopping heat stress damage; load increase or decrease should be slow, rapid acceleration and deceleration, overloading is easy to make the pump instantaneous pressure overload, internal structure Overburdened, strictly adhere to the power red line, so that the diesel fuel pump steady and durable service, drive equipment all the way.
