Why can't a person find the videos they want on Youtube? The thing is that a person cannot come up with something new and look for it. He was out of fantasy. He has already watched a lot of various channels, and he no longer wants to watch anything (from what he watched earlier), but what to do in this situation?
In order to find a Youtube video that suits your needs, it is imperative to keep searching. The harder your search is, the better your search result will be.
Remember that you only need to find a few channels (interesting), and you can watch them for a whole week or even a month. Therefore, in the absence of imagination and unwillingness to search, you can ask your friends and acquaintances what they are looking at on Youtube. Perhaps they will suggest original vloggers that they like. You, too, may like them, and you will become their subscriber!

DIY compressor repair from 416 m
I wash it with gasoline. Your compressor is pumping for a very long time, of course, you need to do an audit
How and what is the best way to flush the compressor before changing the oil? I bought a k31 (11kw motor and s416m piston). It pumps 190l to 9atm in 2:40. It's long, isn't it?

If the wear is with an obvious step, then a replacement cylinder is possible. But do not rush to be disappointed, perhaps it will be enough to put new rings.
But if the piston is no longer round in the skirt, then most likely they did not follow the oil, it may have coked up and evaporated (in consistency like young honey and black), as it was with me,
there is a lot to do. The main thing is to see if the connecting rods are blue (they turn blue from overheating), if they dangle in their places. So gradually determine what to replace and what will work.
For some reason, no one asks the state of the valve head. And this is the most responsible and often dying node.
Piston and connecting rods are not a problem at all in my opinion, everything is sharpened, and bought. In general, everything is bought for repair. This is a big plus!And for some reason they don't ask why my compressor is shaking like a dog? How to balance it?
What, everyone does not jump anywhere after the bulkhead?
I walked around the shop until the pulley was balanced.
In general, this compressor is shit for me, as is often the case in mass-produced Soviet technology. It was produced not in quality, but in quantity. The technique is not licked.
It is necessary to look for a screw alive, this is a technological unit.Post has been editedmetromaxi: 22 December 2016 - 03:35

Bushings 5 from the engine are pressed into the upper heads of the connecting rods ZIL-120 (detail 130-1004052).
Low pressure cylinder connecting rod is lighter.
Piston 1 low-pressure cylinder (Fig. 6), 108 mm in diameter, made of aluminum alloy from the ZIL-375 engine (part 375-1004015-Az).
Three compression rings 2 are installed on the piston: two upper (part 375-1004030) and a lower one (part 375-1004025); one combined oil scraper ring consisting of an axial expander 10 (part 375-1004039), a radial expander 11 (part 375-1004038) and two flat annular discs 12 (part 375-1004041).
The piston is connected to the connecting rod by a floating pin 3 (item 111-1004020), which is held against axial movements by two retaining rings 4 (item 120-1004022).
Piston 1 high pressure cylinder (fig. 7), diameter 52 mm, cast iron. The piston has three compression rings 2 from the compressor of the ZIL-120 car (part 120-3509164A) and one oil scraper.
Piston pin 3 floating type from axial movement is held by two plugs 4. The diameter of the pin is the same as the pin of the low pressure piston.
To ensure proper operation of the compressor, the piston-to-cylinder clearances must be set within the limits shown in table 5.
Compressor head parts are lubricated by splashing oil and oil mist.
To do this, on both connecting rods of the C415M compressor head and on the second and fourth (counting from the flywheel) the connecting rods of the C416M compressor head are installed sprinklers at an angle of 13 ° to the longitudinal axis of the connecting rod.
The sprinkler is a rod that fits snugly into the hole in the connecting rod cover.
In addition, in the large head of the connecting rods, two holes are drilled at an angle to each other and converging into one - these are pockets for collecting oil and supplying it to the connecting rod journals. A central hole is drilled on the upper insert, which should match the hole from the converging “pockets” on the connecting rod.
Breather 4 (Fig. 5), installed on the crankcase cover, serves to communicate the inside of the crankcase with the atmosphere.
To control the oil level in the crankcase, a dipstick 5 (Fig. 3 and 4), installed on one of the side covers, is used.
^ Valve block (Fig. 8) consists of two valve plates: upper (with a cooling rib) 1 and lower 2, connected through a gasket. The valve plates are made of gray cast iron. The valve block contains two suction and two discharge valves and forms a single valve system.
The suction valve of the low-pressure cylinder consists of a valve seat 6, two separators 5, which protect the valve plates from displacement in the horizontal plane, and a socket 4, which limits the deflection of the valve plates. Four valve

plates with a thickness of 0.22 mm overlap the grooves in the saddle and are working elements.The LP cylinder discharge valve consists of four 0.36 mm thick valve plates (which cover the holes in the valve plate), two separators and a rosette.
The suction and discharge valve of the high pressure cylinder has one valve plate each 0.36 mm thick, located in the guide seat. The valve is held in place against longitudinal movement by pins.
^ Air filter 3 (Fig. 3 and 4) is installed on the intake flange of the cylinder head.
The air entering the filter passes through a filter element made on the basis of ultra-thin fiberglass and is directed through a pipe into the suction cavity of the cylinder block cover.
The compressor is cooled by the air flow created by the blades of the flywheel fan. The direction of rotation must be such that the air flow is directed towards the compressor head.
The cooling system maintains the normal temperature of the compressor parts, oil and interstage air cooling.
The collector is also a compressed air pulsation damper.
^ Safety valve installed on the manifold is a signaling device in case of malfunctions in the valve system.
The valve is regulated to a pressure of 0.45 ± 0.03 MPa. When the above pressure rises, the spring, compressed, releases the ball, and the valve communicates the manifold with the atmosphere. When the pressure drops to normal, the ball under the action of the spring closes the hole in the body. The spring is adjusted with a nut and secured with a lock nut. The body, valve head and locknut are sealed.
Pneumatic unloader (fig. 9) is installed on the manifold. Serves to unload the compressor motor at start-up.
The pneumatic relief valve is adjusted so that the valve closes 15 seconds after starting. Adjustment is carried out with nut 7 and lock nut 6.
The receiver (Fig. 10) is a steel welded vessel with convex elliptical bottoms and four supports.
The following are installed on the receiver: control unit 1, which includes: pressure switch, safety valve; air control pressure gauge; check valve block 2, moisture trap 3, terminal box 4, dispensing valve 5.
Compressed air enters the receiver through the discharge pipeline through the check valve (Fig. 14). The non-return valve prevents the compressed air from the receiver back acting on the compressor head when it is stopped.
A moisture trap is used to drain condensate from the receiver (Fig. 11).
When the pressure in the receiver drops to atmospheric, that is, after the compressor is turned off and the residual pressure is released from the receiver, the glass valve 3, in the presence of condensate, floats up and opens the drain hole in the housing 1. After draining, the valve closes.
To maintain the pressure required for operation in the receiver within the set values and to automatically turn on and off the engine, a pressure switch is used (Fig. 12).

Principle pressure switch of a foreign company is based on a comparison of the forces arising from the pressure of compressed air transmitted by the membrane and the forces of elastic deformation of the spring. There is a switch on the relay for manual control of the compressor motor.^ Setting the pressure switch MDR 2/11
The MDR 2/11 relay is configured as follows:
In which direction to rotate the nuts, the adjacent arrows indicate; The + (plus) sign near the arrow indicates an increase in the operating pressure, - (minus) near the arrow indicates a decrease in the operating pressure.
Customization relay pressure MDR1 / 11
The MDR 1/11 relay is configured as follows:
In which direction to rotate the screw, the adjacent arrows indicate. The + (plus) sign near the arrow indicates an increase in the operating pressure, - (minus) near the arrow indicates a decrease in the operating pressure.
The number of revolutions to turn the nut or screw at the setting of the relay is determined directly at the compressor installation empirically, while the change in the pressure value is determined by the pressure gauge on the receiver.
Video (click to play). The pressure switch allows you to adjust the pressure from 0.4 MPa to 1.0 MPa with a difference from min 0.2 MPa to 0.3 MPa.
metromaxiForgot to say thank you for the tip on the earbuds. Thank you =) True, I found it next to the house, the guys are engaged in the restoration of old equipment, just from 51 gas there were salaries.

How was the LP cylinder wear determined?
No probe is worth a penny. Make the breather yourself, turn it for 15 minutes of work. Bushings and fingers change, fingers for 100 rubles, especially if on ND, from the Urals.
Worse with HP, where the piston does not know where.
This ridiculous "problem" is similar to the non-delivery of spare parts for a bike (reflectors and a family man).
The shaft must be watched, maybe just new liners. But even if it is renovated, this is not a problem either.
It is necessary to look at the cylinders, but if they are intact with the pistons, then they can do nothing. ))) Change the rings. Be careful not to mix up the rings when installing, the direction of the grooves.
Use a finger to start with the cylinder. Did you whisper? And how is it there?Post has been editedmetromaxi: 21 December 2016 - 16:27
