Revealing and elimination of the reasons of the increased noise of the engine

All engines should rustle. But at the same time any of shades of noise should not be allocated. More often noise is published with bearings and belts. Happens, that the pump of the hydraulic booster in a rudder, and in overwhelming majority of cases of rustles that in it there is not enough oil.To determine the reason of noise, it is necessary to remove and compare on one belt noise and .

First to remove belts of the hydraulic booster - to start and listen, then - a belt of the pump of the conditioner (it is not out of place for removing in general, not to tropics at us) and again to listen, and the order of removal of belts can be any, convenient for you. However, it is possible to taste from syringe serially to water all belts and if in noise that belt on which working surface water noise will disappear gets is guilty or will change. If all belts are removed, and the engine still rustles (with the removed belt of water cooling the engine of 1-2 minutes can work without consequences), that, means, bearings in rollers on which a gear belt gas distribution rustle. If it (bearings) to change greasing, noise, most likely, will stop. But happens, that greasing any more does not help, it is necessary to change the bearing.

From practice follows, that with the first bearings of the water pump, the generator, a bypass roller, a tension roller start to rustle. Then already others. But, certainly, this all depends on that, belts are how much strongly tense. The the belt is more strongly tense, the will more strongly rustle (and then the bearing something will collapse), that is resulted in rotation by this belt. When belts are removed, it is possible to twist fingers any roller (or a shaft if it is a question, for example, about the generator). Making it, closely listen. If at rotation you feel a rhythmical roar of rollers which are rolled inside of the bearing this bearing should change greasing immediately. If at rotation you will feel even one jamming or a roar of balls spasmodic - it is necessary to change the bearing because at it (it is visible on paths on which balls slide) the surface has already started to be painted and from it anywhere will not get to.

If at the bearing is any feel backlash (shake the platen which in it press on or an external holder concerning internal) also search new. In the old bearing it is possible to put in pawn new greasing and to do a bit of travelling it is a little, but only in the event that it costs somewhere in the generator or in the pump of the conditioner. If it is installed, for example, in a tension roller of a gear belt gas distribution on the diesel engine do not risk, estimate, in what to you repair when the bearing with backlash will collapse will manage or will jam.

Often happens, that start drivebelts (for example, the generator).
Do not rush to pull this belt at once. Perhaps, it that chock any the bearing or this belt has simply grown old: rubber on it tanned, here it and slip. To tighten a belt it is possible, but loading on the bearing (generator) that will not add to it longevity at once will increase.
